Unit 3

THERM/THERMO

THERM/THERMO comes from the Greek word meaning “warm.” A thermometer measures the amount of warmth in a body, the air, or an oven. A thermostat makes sure the temperature stays at the same level. And it’s easy to see why the German manufacturers of a vacuum-insulated bottle back in 1904 gave it the name Thermos.

POLY

POLY comes from polys, the Greek word for “many.” A polytechnic institute offers instruction in many technical fields. Polygamy is marriage in which one has many spouses, or at least more than the legal limit of one. And polysyllabic words are words of many syllables—of which there are quite a few in this book.

  • polyp
    1).A sea invertebrate that has a mouth opening at one end surrounded by stinging tentacles.
    2).A growth projecting from a mucous membrane, as on the colon or vocal cords.

  • polyglot

    An instrument for recording changes in several bodily functions (such as blood pressure and rate of breathing) at the same time; lie detector.

    1).A small book for teaching children to read.
    2).A small introductory book on a subject.

  • primate
    Any member of the group of animals that includes human beings, apes, and monkeys.

  • primordial
    1).First created or developed.
    2).Existing in or from the very beginning.

HOM/HOMO

HOM/HOMO comes from homos, the Greek word for “same,” which in English words may also mean “similar.” A homograph is a word spelled like another word but different in meaning or pronunciation, and a homosexual is a person who favors others of the same sex. (This root has nothing to do with the Latin homo, meaning “person,” as in Homo sapiens, the French homme, and the Spanish hombre.)

  • homonym
    One of two or more words pronounced and/or spelled alike but different in meaning.

  • homogeneous
    1).Of the same or a similar kind.
    2).Of uniform structure or composition throughout.

  • homologous

  • homogenize
    1).To treat (milk) so that the fat is mixed throughout instead of floating on top.
    2).To change (something) so that its parts are the same or similar.

DIS

DIS comes from Latin, where it means “apart.” In English, its meanings have increased to include “opposite” or “not” (as in distaste, disagreeable), “deprive of” (disinfect), or “exclude or expel from” (disbar). The original meaning can still be seen in a word like dissipate, which means “to break up and scatter.”

  • dissuade
    To convince (someone) not to do something.

  • disorient
    To cause to be confused or lost.

  • discredit
    1).To cause (someone or something) to seem dishonest or untrue.
    2).To damage the reputation of (someone).

    To force out of a place, especially a place of rest, hiding, or defense.

Latin Borrowings

Unit 4

VOR

VOR comes from the Latin verb vorare, “to eat,” and the ending -ivorous shows up in words that refer to eaters of certain kinds of food. Frugivorous (for “fruit-eating”), granivorous (for “grain-eating”), and graminivorous (for “grass-eating”) aren’t too rare, but you won’t run across phytosuccivorous (“plant-sap-eating”) every day.

  • carnivorous
    Meat-eating or flesh-eating.

  • herbivorous
    Plant-eating.

  • insectivorous
    Feeding on insects.

  • voracious
    Having a huge appetite.

CARN

CARN comes from a Latin word meaning “flesh” or “meat.” Carnation originally meant “the color of flesh,” which was once the only color of the flower we call the carnation. In Christian countries, Lent is the period when the faithful traditionally give up something they love, often meat. The days leading up to Lent are known as the carnival season, from the Italian carnelevare, later shortened to carnevale, which meant “removal of meat”— though during carnival, of course, people indulge in just about everything, and the removal of meat only comes later.

  • carnage
    Great destruction of life (as in a battle); slaughter.

  • carnal
    Having to do with bodily pleasures.

  • incarnate
    Given bodily or actual form; especially, having human body.

  • reincarnation
    1).Rebirth in new bodies or forms of life.
    2).Someone who has been born again with a new body after death.

CRED comes from credere, the Latin verb meaning “to believe” or “to entrust.” We have a good credit rating when institutions trust in our ability to repay a loan, and we carry credentials so that others will believe that we are who we say we are.

  • credible
    1).Able to be believed; reasonable to trust or believe.
    2).Good enough to be effective.

  • credo
    1).A statement of the basic beliefs of a religious faith.
    2).A set of guiding principles or beliefs.

FID

FID comes from fides, the Latin word for “faith” or “trust.” Fidelity is another word for “faithfulness.” Confidence is having faith in someone or something. An infidel is someone who lacks a particular kind of religious faith. And the once-popular dog’s name Fido is Latin for “I trust.”

  • affidavit
    A sworn statement made in writing.

  • diffident
    Lacking confidence; timid, cautious.

  • fiduciary
    1).Having to do with a confidence or trust.
    2).Held in trust for another.

  • perfidy
    Faithlessness, disloyalty, or treachery.

CURR/CURS

CURR/CURS comes from currere, the Latin verb meaning “to run.” Although words based on this root don’t tend to suggest speed, the sense of movement remains. Current, for instance, refers to running water in a stream or river, or electrons running through a wire, and an excursion is a trip from one place to another.

  • concurrent
    Happening or operating at the same time.

  • cursory
    Hastily and often carelessly done.

  • discursive
    Passing from one topic to another.

  • precursor
    One that goes before and indicates the coming of another.

PED

PED comes from the Latin word for “foot.” A pedal is pushed by the foot; a pedicure is a treatment of the feet, toes, and toenails; and a pedestal is what a statue stands on—in a sense, its foot.

  • quadruped
    An animal having four feet.

  • pedigree
    The line of ancestors of a person or animal.

  • impediment
    Something that interferes with movement or progress.

  • pedestrian
    Commonplace, ordinary, or unimaginative.

FLECT

FLECT comes from flectere, the Latin verb meaning “to bend.” The root sometimes takes the form flex-. Things that are flexible can be bent, and when you flex a muscle, you’re usually bending a limb—which, as a trainer at the gym will tell you, requires the use of flexor muscles.

  • deflect
    To turn aside, especially from a straight or fixed course.

  • reflective
    1).Capable of reflecting light, images, or sound waves.
    2).Thoughtful.

  • genuflect
    To kneel on one knee and then rise as an act of respect.

  • inflection
    1).A change in the pitch, tone, or loudness of the voice.
    2).The change in form of a word showing its case, gender, number, person, tense, mood, voice, or comparison.

POST

POST comes from a Latin word meaning “after” or “behind.” A postscript (or PS) is a note that comes after an otherwise completed letter, usually as an afterthought. Postpartum refers to the period following childbirth, with any related events and complications. To postdate a check is to give it a date after the day it was written.

  • posterior

  • posthumous
    1).Published after the death of the author.
    2).Following or happening after one’s death.

    1).Occurring after death.
    2).Following the event.

VIS

VIS comes from a Latin verb meaning “see.” Vision is what enables us to see, visual images are visible to our eyes, and a visitor is someone who comes to see something.

And a vocabulary is a set of words for speaking.

PHON

PHON is a Greek root meaning “sound,” “voice,” or “speech.” It’s probably most familiar in the form of the English suffix -phone, in words that begin with a Greek or Latin root as well. Thus, the tele- in telephone means “far,” the micro- in microphone means “small,” the xylo- in xylophone means “wood,” and so on.

MOR/MORT comes from Latin words meaning “to die” and “death.” A mortuary is a place where dead bodies are kept until burial, and a postmortem examination is one conducted on a recently dead body. The Latin phrase “Memento mori” means “Remember that you must die”; so a memento mori is the name we give to a reminder of death; the skulls you can find carved on gravestones in old cemeteries are examples.

COSM

COSM comes from the Greek word for “order.” Since the Greeks believed the universe was an orderly place, words in this group usually relate to the universe. So cosmonaut was the word for a space traveler from the former Soviet Union. (The roots of our own word, astronaut, suggest “star traveler” instead.) Oddly enough, cosmetics comes from the same root, since putting things in order is similar to decorating something—such as your face.

Unit 10

PUT

PUT comes from the Latin verb putare, meaning “to think, consider, or believe.” So, for example, a reputation is what others think of you. But when the root shows up in such words as compute, dispute, and deputy, its meaning is harder to trace.

  • reputed
    Believed to be a certain way by popular opinion.

  • disrepute
    Loss or lack of good reputation; disgrace.

  • impute
    To attribute.

  • putative
    Generally supposed; assumed to exist.

LOG

LOG, from the Greek word logos, meaning “word,” “speech,” or “reason,” is found particularly in English words that end in -logy and -logue. The ending logy often means “the study of”; so, for instance, biology is the study of life, and anthropology is the study of humans. And -logue usually indicates a type of discussion; thus, dialogue is conversation between two people or groups, and an epilogue is an author’s last words on a subject. But exceptions aren’t hard to find.

  • physiology
    1).A branch of biology dealing with the processes and activities by which living things, tissues, and cells function.
    2).The life processes and activities of a living thing or any of its parts.

TERR

TERR comes from the Latin terra, “earth.” A territory is a large expanse of land. Terra firma is Latin for “firm ground” as opposed to the swaying seas. A terrace is a leveled area, often one created for farming on a sloping hill. And the French word for potato, pomme de terre, means literally “apple of the earth.”

  • parterre
    1).A decorative garden with paths between the beds of plants.
    2).The back area of the ground floor of a theater, often under the balcony.

  • subterranean

  • terrestrial
    1).Having to do with Earth or its inhabitants.
    2).Living or growing on land instead of in water or air.

MAR

MAR, from the Latin word mare, meaning “sea,” brings its salty tang to several English words. A submarine is an undersea ship. Marine means basically “relating to the sea,” so when the Continental Marines were established back in 1775, their job was to provide on-board security on naval ships; but they immediately began to be used on land as well, and the marines have continued to operate on both land and sea ever since.

  • marina
    A dock or harbor where pleasure boats can be moored securely, often with facilities offering supplies or repairs.

  • aquamarine
    1).A transparent blue or blue-green gem.

    2).An emotion of sympathetic pity.

  • apathetic
    1).Showing or feeling little or no emotion.
    2).Having no interest.

  • empathy
    The feeling of, or the ability to feel, the emotions and sensations of another.

  • telepathic
    Involving apparent communication from one mind to another without speech or signs.

PEN/PUN

  • penal
    Having to do with punishment or penalties, or institutions where punishment is given.

  • impunity
    Freedom from punishment, harm, or loss.

  • penance
    An act of self-punishment or religious devotion to show sorrow or regret for sin or wrongdoing.

  • punitive

MATR/MATER

MATR/MATER comes from the Greek and Latin words for “mother.” A matron is a mature woman with children. And matrimony is marriage itself, the traditional first step toward motherhood.

  • maternity
    The state of being a mother; motherhood.

  • matriarch
    A woman who controls a family, group, or government.

  • matrilineal

AQU

AQU comes from aqua, the Latin word for “water.” We keep pet fish in an aquarium at home or visit larger sea animals in a building with that name. Water sports such as swimming, canoeing, and sailing are sometimes called aquatics. In Scandinavia there’s a popular drink called aquavit, the name coming from the Latin aqua vitae, “water of life”—though instead of water it mostly consists of alcohol.

  • aquaculture
    The farming of plants and animals (such as kelp, fish, and shellfish) that live in the water.

  • aquanaut
    A scuba diver who lives and works both inside and outside an underwater shelter for an extended time.

Unit 11

CANT

CANT, from the Latin verb cantare, meaning “sing,” produces several words that come directly from Latin. But some others came to English by way of French, which added an h to the root, giving us such words as chant and chantey.

  • cantata
    A musical composition, particularly a religious work from the 17th or 18th century, for one or more voices accompanied by instruments.

  • incantation
    1).A use of spells or verbal charms spoken or sung as part of a ritual of magic.

  • descant
    An additional melody sung above the principal melody.

LINGU

LINGU comes from the Latin word that means both “tongue” and
“language,” and in English today tongue can still mean “language” (as in “her native tongue”). Our expression “slip of the tongue” is just a translation of the Latin phrase lapsus linguae. The root even shows up in a slangy-sounding word like lingo. And since lingu- changed to langu- in French, our word language is related as well.

  • linguistics
    The study of human speech.

  • multilingual
    Using or able to use several languages.

  • lingua
    franca A language used as a common or commercial language among peoples who speak different languages.

  • linguine

SPIR

SPIR comes from the Latin words meaning “breath” and “breathe.” When we inspire others—that is, give them inspiration—it’s as though we’re breathing new energy and imagination into them. When you expire, or die, you “breathe out” your soul in your last breath. A license, membership, credit card, or free offer may also expire, at a time indicated by its expiration date.

  • spirited
    Full of energy or courage; very lively or determined.

  • dispiriting
    Causing a loss of hope or enthusiasm.

  • turbid
    1).Thick or murky, especially with churned-up sediment.

2).Unclear, confused, muddled.

THE/THEO

THE/THEO comes from the Greek word meaning “god.” Theology, the study of religion, is practiced by theologians. Monotheism is the worship of a single god; Christianity, Islam, and Judaism are monotheistic religions, and all three worship the same god. Polytheistic religions such as those of ancient Greece and Rome, on the other hand, worship many gods.

ICON

ICON comes from the Greek eikon, which led to the Latin icon, both meaning “image.” Though the icon- root hasn’t produced many English words, the words that is does appear in tend to be interesting.

  • icon
    1).A religious image usually painted on a small wooden panel: idol.
    2).Emblem, symbol.

    1).Symbolic.

    Sophisticated and with polished manners.

  • exurban
    Relating to a region or settlement that lies outside a city and usually beyond its suburbs and often is inhabited chiefly by well-todo families.

DEM/DEMO

DEM/DEMO comes from the Greek word meaning “people.” “Government by the people” was invented by the ancient Greeks, so it’s appropriate that they were the first to come up with a word for it: demokratia, or democracy.

  • demographic
    Having to do with the study of human populations, especially their size, growth, density, and patterns of living.

  • endemic
    1).Found only in a given place or region.

  • accord
    1).To grant.
    2).To be in harmony; agree.

  • concord
    1).A state of agreement: harmony.

    To accuse or incriminate; to show evidence of someone’s involvement in a fault or crime.

GNI/GNO

GNI/GNO comes from a Greek and Latin verb meaning “to know,” and can be found at the root of know itself. Among other words built from this root, you may recognize (“know again”) some and be ignorant of (“not know”) others. But only an ignoramus would know absolutely none of them.

  • cognitive
    1).Having to do with the process of knowing, including awareness, judgment, and understanding.
    2).Based on factual knowledge that has been or can be gained by experience.

GRAPH

GRAPH comes from the Greek verb graphein, “to write.” Thus, a biography is a written account of someone’s life (see BIO), a discography is a written list of recordings on disc (records or CDs), and a filmography is a list of motion pictures. But lots of uses of -graph and -graphy don’t mean literally “writing” (as in autograph or paragraph), but instead something more like “recording,” as in photography, seismograph, or graph itself.

  • calligraphy
    The art of producing beautiful handwriting.

  • hagiography
    1).Biography of saints.
    2).Biography that idealizes or idolizes.

ART

ART comes from the Latin word for “skill.” This reminds us that, until a few centuries ago, almost no one made a strong distinction between skilled craftsmanship and what we would now call “art.” And the word art itself could also mean simply “cleverness.” The result is that this root appears in some words where we might not expect it.

  • artful
    1).Skillful.
    2).Wily, crafty, sly.

  • artifact
    A usually simple object made by human workmanship, such as a tool or ornament, that represents a culture or a stage in a culture’s development.

    1).Clever skill.
    2).A clever trick.

    1).The building of military defenses to protect a place against attack.
    2).A structure built to protect a place.

Unit 14

CRYPT

CRYPT comes from the Greek word for “hidden.” To encrypt a message is to encode it—that is, to hide its meaning in code language. When a scientific term begins with crypto-, it always means that there’s something hidden about it .

  • crypt
    1).A room completely or partly underground, especially under the main floor of a church.
    2).A room or area in a large aboveground tomb.

AB/ABS comes to us from Latin, and means “from,” “away,” or “off.” Abuse is the use of something in the wrong way. To abduct is to “lead away from” or kidnap. Aberrant behavior is behavior that “wanders away from” what is acceptable. But there are so many words that include these roots that it would be absurd to try to list them all here.

  • abscond
    To depart in secret and hide.

  • abstemious
    Restrained, especially in the consumption of food or alcohol.

  • abstraction
    The consideration of a thing or idea without associating it with a particular example.

  • abstruse
    Hard to understand; deep or complex.

PED-

PED- comes from the Greek word for “child.” The same root also has the meaning “foot” (see PED), but in English words it usually isn’t hard to tell the two apart.

  • pedagogy
    The art, science, or profession of teaching.

  • pedant
    1).A formal, unimaginative teacher.
    2).A person who shows off his or her learning.

TROP comes from the Greek tropos, meaning “turn” or “change.” The troposphere is the level of the atmosphere where most weather changes—or “turns in the weather”—occur. And the Tropics of Cancer and Capricorn are the lines of latitude where the sun is directly overhead when it reaches its northernmost and southernmost points, on about June 22 and December 22 every year—that is, the point where it seems to turn and go back the other way.

  • tropism

    Any of a genus of herbs or shrubs having small white or purple flowers.

  • psychotropic
    Acting on the mind.

NEO

NEO comes from the Greek neos, meaning “new.” Neo- has become a part of many English words. Some are easy to understand; for example, neo-Nazi. Some are less so; you might not immediately guess that neotropical means
“from the tropics of the New World,” or that a neophyte is a “newcomer.” When William Ramsay discovered four new gases, he named them all using Greek roots that at first glance might sound slightly mysterious: argon (“idle”), krypton (“hidden”), xenon (“strange”)—and neon (“new”).

  • neoclassic
    Relating to a revival or adaptation of the styles of ancient Greece and Roman, especially in music, art, or architecture.

  • neoconservative
    A conservative who favors strongly encouraging democracy and the U.S. national interest in world affairs, including through military means.

The long-running PBS show Nova keeps its large audience up to date on what’s new in the world of science. And when the British king sent Scottish settlers to a large island off Canada’s Atlantic coast in the 17th century, he named it Nova Scotia, or “New Scotland.”

  • novice

TEN

TEN, from the Latin verb tenere, basically means “hold” or “hold on to.” A tenant is the “holder” of an apartment, house, or land, but not necessarily the owner. A lieutenant governor may “hold the position” ( “serve in lieu”) of the governor when necessary.

TOP comes from topos, the Greek word for “place.” A topic is a subject rather than a place; to the Greeks, the original word meant more or less “about one place or subject (rather than another)”—which just goes to show that it’s not always easy to trace a word’s meaning from its roots.

  • topical
    1).Designed for local application to or treatment of a bodily part.

In the Bible, King Ahasuerus, angered by his queen’s disobedience, proclaims that “every man is to be master of his own house,” and in the Roman empire no one doubted that this was how it was meant to be. A domain is the area where a person has authority or is dominant—but we no longer think of a house as the domain of a single dominant member of a family.

Without the capital letter, catholic means simply “universal” or, when describing a person, “broad in one’s interests or tastes.”

  • holistic
    Relating to or concerned with wholes or with complete systems rather than with the analysis of, treatment of, or dissection into parts.

It’s less easy to see how we get temperature from this root; the word actually used to refer to the mixing of different basic elements in the body, and only slowly came to mean how hot or cold that body was.

    A brief, often-repeated statement that expresses a general truth or common observation.

  • verbatim

SIMIL/SIMUL

SIMIL/SIMUL come from the Latin adjective similis, meaning “like, resembling, similar,” and the verb simulare, “to make like.” Two similar things resemble each other. Two simultaneous activities proceed at the same time. And a facsimile, such as you might receive from your fax machine, looks exactly the same as the original.

ONYM

ONYM comes from the Greek onyma, meaning “name, word.” An anonymous donor or writer is one who isn’t named. A synonym is a word with the same meaning as another word (see SYN). And homonyms (see HOM/HOMO) are words that look and sound alike but aren’t actually related, such as well (“healthy”) and well (“a deep hole with water in it”).

  • antonym
    A word that means the opposite of some other word.

  • eponymous

FALL

FALL comes from the Latin verb fallere, “to deceive.” It’s actually at the root of the word false, which we rarely use today to mean “deceptive,” though that meaning does show up in older phrases: “Thou shalt not bear false witness against thy neighbor,” for instance, or “A false-hearted lover will send you to your grave.” Fallere is even at the root of fail and fault, though you might not guess it to look at them.

  • fallacy
    A wrong belief; a false or mistaken idea.

  • fallacious
    Containing a mistake; not true or accurate.

  • fallibility
    Capability of making mistakes or being wrong.

  • infallible
    1).Not capable of being wrong or making mistakes.

2).Certain to work properly or succeed.

SOLU

SOLU comes from the Latin verb solvere, “to loosen, free, release,” and the root therefore may take the form solv- as well. So to solve a problem means to find its solution, as if you were freeing up a logjam. And a solvent is a chemical that dissolves or “loosens up” oil or paint.

    1).Able to be dissolved in a liquid, especially water.
    2).Able to be solved or explained.

MUR, from the Latin noun murus, meaning “wall,” has produced a modest number of English words.

  • muralist
    A painter of wall paintings.

  • intramural
    Existing or occurring within the bounds of an institution, especially a school.

  • extramural
    Existing outside or beyond the walls or boundaries of an organized unit such as a school or hospital.

  • immure
    To enclose within, or as if within, walls; imprison.

POLIS/POLIT

POLIS/POLITcomes from the Greek word for “city.” The ancient Greek city-states, such as Athens, Thebes, and Sparta, operated much like separate nations, so all their politics was local, like all their public policy—and even all their police!

  • politic
    1).Cleverly tactful.
    2).Wise in promoting a plan or plan of action.

  • politicize
    To give a political tone or character to.

  • numerology
    The study of the occult significance of numbers.

  • alphanumeric
    Having or using both letters and numbers.

  • enumerate
    To specify one after another; list.

  • supernumerary

KILO

KILO is the French version of the Greek word chilioi, meaning “thousand.” France is also where the metric system originated, in the years following the French Revolution. So in English, kilo- shows up chiefly in metric-system units. Before the computer age, the most familiar kilo- words for Englishspeakers were probably kilowatt, meaning “1,000 watts,” and kilowatt-hour, meaning the amount of energy equal to one kilowatt over the course of an hour.

  • kilobyte
    A unit of computer information equal to 1,024 bytes.

  • kilometer
    A unit of length equal to 1,000 meters.

  • kilohertz
    A unit of frequency equal to 1,000 cycles per second.

  • kilogram
    A unit of weight equal to 1,000 grams.

MICRO

MICRO, from the Greek mikros, meaning “small,” is a popular English prefix. A microscope lets the eye see microscopic objects, and libraries store the pages of old newspapers on microfilm at 1/400th of their original size. And we continue to attach micro- to lots of familiar words; most of us could figure out the meaning of microbus and microquake without ever having heard them before. Scientists often use micro- to mean “millionth”; thus, a microsecond is a millionth of a second, and a micrometer is a millionth of a meter.

  • microbe
    An organism (such as a bacterium) of microscopic or less than microscopic size.

  • microbiologist
    A scientist who studies extremely small forms of life, such as bacteria and viruses.

  • microbrew
    A beer made by a brewery that makes beer in small amounts.

  • multidisciplinary
    Involving two or more subject areas.

  • multifarious
    Having or occurring in great variety; diverse.

  • multilateral
    Involving more than two nations or parties.

PAR

PAR, from the Latin, means “equal.” Our English word par means an amount taken as an average or a standard, and especially the standard score for each hole on a golf course—which is why the phrase “par for the course” means “about as well as expected.” We compare things to see if they’re equal; similar things can be called comparable—that is, “equal with.” And “on a par with” means “comparable to.”

  • parity
    The state of being equal.

  • disparity
    A noticeable and often unfair difference between people or things.

  • nonpareil
    Someone or something of unequaled excellence.

  • subpar
    Below a usual or normal level.

PHOB

PHOB comes from the Greek noun phobos, “fear,” and it shows up clearly in our noun phobia, meaning “unusual fear of a specific thing.” Phobias vary greatly in seriousness and also in frequency. Most of us have experienced claustrophobia at some time, but few truly suffer from fear of the number 13, a condition known as triskaidekaphobia.

  • acrophobic
    Fearful of heights.

  • agoraphobia
    A fear of being in embarrassing or inescapable situations, especially in open or public places.

  • xenophobe
    One who has a fear or hatred of strangers or foreigners.

  • arachnophobia
    Having a fear or dislike of spiders.

HEM/HEMO

HEM/HEMO comes from the Greek word for “blood” and is found at the beginning of many medical terms. By dropping the h-, the same word produced the suffix -emia, which likewise shows up in lots of “blood” words, including anemia, leukemia and hyperglycemia.

  • hemorrhage
    1).A large loss of blood from a blood vessel.
    2).A rapid and uncontrollable loss or outflow.

  • hematology
    The study of blood and blood-forming organs.

  • hemophilia
    A bleeding disorder caused by the blood’s inability to coagulate.

  • hemoglobin
    The element in blood that transports oxygen from the lungs to the body’s tissues and transports carbon dioxide from the tissues back to the lungs.

ITIS

ITIS, a suffix found in both Greek and Latin, means “disease” or “inflammation.” In appendicitis your appendix is swollen and painful, and in tonsillitis the same is true of your tonsils. With laryngitis, your throat and larynx may become so sore that it’s difficult to talk. Some of us enjoy making up our own -itis words; high-school teachers, for example, long ago noticed that many of their seniors tended to lose all interest in schoolwork and start skipping classes, and labeled the condition senioritis.

  • bursitis
    Inflammation of a lubricating sac (bursa), especially of the shoulder or elbow.

  • hepatitis
    Inflammation of the liver.

  • bronchitis
    Inflammation of the bronchial tubes.

  • tendinitis
    A painful condition in which a tendon in the arm or leg becomes inflamed.

Unit 27

NANO

NANO comes from the Greek nanos, meaning “dwarf.” For a prefix meaning “small,” English got by for centuries with the Greek micro-, and later minicame to be used widely as well. But only recently, as a result of advances in scientific knowledge and technology, has there been a need for a prefix meaning “extremely small”—a need that’s been filled by nano-, which today is being attached to all kinds of words, sometimes not very seriously (nanoskirt, nano-brained, etc.).

  • nanotechnology
    The science of manipulating materials on an atomic or molecular scale, especially to build microscopic devices such as robots.

  • nanosecond
    One billionth of a second.

  • nanostructure
    An arrangement, structure, or part of something of molecular dimensions.

  • nanoparticle
    A tiny particle whose size is measured in billionths of a meter.

SUPER

SUPER, a Latin prefix meaning “over, higher, more than,” has become one of the most familiar prefixes in English, one of those prefixes that we use to create new words all the time: supermodel, superpowerful, superjock, supersize, supersweet—the list goes on and on. This all seems to have started in 1903 when the playwright G. B. Shaw translated the German word

  • superfluous
    Beyond what is needed; extra.

  • insuperable
    Incapable of being solved or overcome.

  • supersede
    To take the place of; to replace with something newer or more useful.

  • superlative
    Supreme, excellent.

DE

DE in Latin means “down, away.” So a descent is a downward slope or climb, and a decline is a downward slide (of health, income, etc.). To devalue something is to take value away from it. And you might describe a depressed friend as “down.”

  • debase
    To lower the value or reputation of someone or something.

  • defamation
    The harming of someone’s reputation by libel or slander.

  • degenerative
    Causing the body or part of the body to become weaker or less able to function as time passes.

  • dejection
    Sadness, depression, or lowness of spirits.

NUL/NULL

NUL/NULL comes from the Latin word nullus, “none,” which is itself a combination of ne- (“not”) and ullus (“any”). Have you ever noticed how many of our negative words start with n-

  • null
    1).Having no legal power; invalid.
    2).Having no elements.

  • nullity
    1).Nothingness.
    2).A mere nothing.

  • nullify
    1).To cancel legally.

    An agreement to stop fighting a war; a truce.

  • armory
    A place where weapons are made or stored.

  • disarming
    Tending to remove any feelings of unfriendliness or distrust.

    A rapid or sudden increase or rise.

    A usually violent attempt to take control of a government; a rebellion or uprising.

  • counterinsurgent
    A person taking military or political action against guerrillas or revolutionaries.

  • resurgent
    Rising again into life, activity, or prominence.

STRAT

STRAT comes from the Latin word stratum, meaning “spread” or “bed.” Strata, a form of the same word, came to be used by the Romans to mean “paved road”—that is, street.

  • stratum
    1).A layer of a substance, especially one of a series of layers.
    2).A level of society made up of people of the same rank or position.

  • stratification
    The process or state of being formed, deposited, or arranged in layers.

  • substrate
    1).An underlying layer.
    2).The base on which an organism lives.

  • stratocumulus
    A low-lying cloud formation appearing as extensive and often dark horizontal layers, with tops rounded into large balls or rolls.

LATER

LATER comes from the Latin adjective lateralis, meaning “side.” The noun for “side” in Latin was latus, and the same word served as an adjective meaning “wide.” The relationship between the two isn’t hard to spot, since something wide extends far out to its sides. So lines of latitude extend eastwest around the earth, in the dimension we tend to think of as its width (unlike lines of longitude, which extend north-south, in the dimension that, for some reason, we decided to think of as its “length”).

  • lateral
    Of or relating to the side.

  • bilateral
    Involving two groups or countries.

  • collateral
    1).Associated but of secondary importance.
    2).Related but not in a direct or close way.

  • equilateral
    Having all sides or faces equal.

TOM

TOM comes from the Greek root meaning “cut.” Thus, the Latin word anatomia, from which we get anatomy, means “dissection”—that is cutting or separating the parts of an organism for detailed examination. In a lobotomy, the nerves linking a brain lobe to the rest of the brain are removed; even though lobotomies have hardly been performed in the last 50 years, the idea can still fill us with horror.

  • appendectomy
    Surgical removal of the human appendix.

  • gastrectomy
    Surgical removal of all or part of the stomach.

  • tonsillectomy
    Surgical removal of the tonsils.

  • mastectomy
    Surgical removal of all or part of the breast.

IATR

IATR, from the Greek iatros, “healer, physician,” usually hides in the middle of words, where it isn’t immediately noticed. A pediatrician treats children (see PED-). A psychiatrist is a physician who treats mental problems. (A psychologist, by contrast, doesn’t have a medical degree and thus can’t prescribe drugs.) And a physiatrist is a doctor who practices “physical medicine and rehabilitation,” which may involve such things as testing various physical abilities, relieving pain through electric heat or massage, or training patients to exercise or to use an artificial limb.

  • iatrogenic
    Caused accidentally by medical treatment.

  • bariatric
    Relating to or specializing in the treatment of obesity.

  • geriatric
    Of or relating to old people.

  • podiatrist
    A doctor who treats injuries and diseases of the foot.

Unit 28

MEDI

MEDI comes from the Latin medius, meaning “middle.” Our word medium refers to something in a middle position. The medieval period of European history, also known as the Middle Ages, is the period between Greek and Roman antiquity and the “modern age.” But why people around 1620 began to use the term “Middle Ages,” because they regarded themselves as modern, is an interesting question.

  • median
    In the middle; especially, having a value that is in the middle of a series of values arranged from smallest to largest.

  • mediate
    1).To work with opposing sides in an argument or dispute in order to get an agreement.
    2).To achieve a settlement or agreement by working with the opposing sides.

  • intermediary
    A person who works with opposing sides in a dispute in order to bring about an agreement.

  • mediocrity
    The quality of being not very good.

OID

OID comes from the Greek word for “appearance” or “form.” Since aster in ancient Greek meant “star,” the small bodies orbiting between Mars and Jupiter that looked like stars through primitive telescopes were called asteroids. A factoid is a little bit of information that looks like a fact, whether it is or not. And some people these days will attach -oid to just about anything; you can probably figure out the meaning of nutsoid, nerdoid, and freakazoid without much help.

  • rhomboid
    In geometry, a shape with four sides where only the opposite sides and angles are equal.

  • deltoid
    A large muscle of the shoulder.

  • humanoid
    Looking or acting like a human.

SCOP

SCOP, which usually appears in a suffix, comes from the Greek skopein, meaning “to look at.” In English we have the simple noun scope, along with some other words it sometimes stands for: telescope, microscope, periscope, and so on. And have you ever used a stereoscope, a device your greatgrandparents probably enjoyed, which lets you look through a viewer at two slightly different photographs of the same thing, one with each eye, to enjoy the illusion that you’re seeing it in three dimensions

  • endoscope
    A lighted tubular medical instrument for viewing the interior or a hollow organ or body part that typically has one or more channels to permit passage of surgical instruments.

  • arthroscopic
    Relating to a fiber-optic instrument that is inserted through an incision near a joint to examine the joint’s interior.

  • laparoscopy
    Examination of the interior of the abdomen using a fiber-optic instrument inserted through a cut in the abdomen’s wall.

  • oscilloscope
    An instrument that shows visual images of changing electrical current on a screen.

TRANS

TRANS comes from Latin to indicate movement “through, across, or beyond” something. Translation carries a writer’s meaning from one language to another. A television signal is sent or transmitted through the air (or a cable) to your set. When making your way through a city on public transportation, you may have to transfer from one bus or subway to another.

  • transient
    1).Not lasting long; short-lived.
    2).Passing through a place and staying only briefly.

  • transfiguration
    A change in form or appearance; a glorifying spiritual change.

  • transponder
    A radio or radar set that emits a radio signal after receiving such a signal.

  • transcendent
    1).Exceeding or rising above usual limits;

    2).Beyond comprehension; beyond ordinary experience or material existence.

PRO is an important prefix, with a couple of quite different broad meanings. In this section, we’ll look at words in which pro- has the basic meaning “for” or “favoring.” Everyone knows words like pro-democracy and pro-American, but other pro- words may not be quite so self-explanatory.

  • proactive
    Acting in anticipation of future problems, needs, or changes.

  • pro
    bono Being, involved in, or doing professional work, and especially legal work, donated for the public good.

  • proponent
    One who argues in favor of something: advocate.

  • pro
    forma Done or existing as something that is required but that has little true meaning or importance.

  • protrude
    To jut out from the surrounding surface or context.

  • prophylaxis
    Measures designed to preserve health and prevent the spread of disease.

  • promulgate
    1).To proclaim or make public.
    2).To put (a law) into effect.

  • prologue
    1).An introduction to a literary work.
    2).An introductory event or development.

RE

RE is a prefix which, like pro- (see PRO), has more than one meaning. In this section, we’ll focus on the meaning “again.” We use re- words with this meaning every day—redo, reheat, recheck, reread, resell, repaint, etc.—and we feel free to make up new ones as needed. But in plenty of other re- words, the meaning isn’t so obvious.

  • remorse
    A deep regret arising from a sense of guilt for past wrongs.

  • reiterate
    To state or do over again or repeatedly.

  • rejuvenate
    To make young or youthful again; to give new vigor to.

  • reconcile
    1).To make agree.
    2).To make friendly again.

RE-

RE-, in its other main sense, means “back” or backward." Since doing something again means going back to it, the two senses are actually related; still, the meaning of re- in most words is pretty clearly one or the other. So a rebound comes back at you; to recall means to “call back” a memory; and to react is to “act back” at someone else’s action.

  • reciprocal
    1).Done, given, or felt equally by both sides.
    2).Related to each other in such a way that one completes the other or is the equal of the other.

  • rebut
    1).To oppose by argument.
    2).To prove to be wrong.

  • revoke
    To officially cancel the power or effect of something (such as a law, order, or privilege).

  • regress
    To return to an earlier and usually worse or less developed condition or state.

DERM

DERM comes from the Greek derma, meaning “skin.” For medical advice on a skin problem such as acne, we may go to a dermatologist, or skin specialist. When we get a shot, it’s usually with a hypodermic, a needle that goes “under the skin” (see HYP/HYPO). A pachyderm is a “thick-skinned” animal, which most of us just call an elephant.

  • dermal
    Relating to the skin and especially to the dermis.

  • epidermis
    The outer layer of the skin.

  • taxidermist
    One who prepares, stuffs, and mounts the skins of dead animals.

  • dermatitis
    Inflammation of the skin.

ENDO

ENDO comes from the Greek endon, meaning “within.” In English it appears almost always in scientific terms, especially in biology. A nonscientific endoword is endogamy, meaning marriage within a specific group as required by custom or law—one of the many customs that can be seen everywhere from the most remote tribes to the highest society in wealthy countries.

  • endocrine
    1).A hormone.
    2).Any of several glands (such as the thyroid) that pour their secretions directly into the blood or lymph.

  • endogenous
    Developing or originating within a cell, organ, body, or system.

  • endorphin
    Any of a group of proteins in the brain that are able to relieve pain.

Unit 29

NECRO

NECRO comes from the Greek nekros, meaning “dead body,” so it’s not surprising that it shows up in some unappetizing places. A necrophagous insect, for instance, is one that feeds on dead bodies; when homicide investigators discover a corpse, they may use the insect evidence to figure out when the person died.

  • necrosis
    Death of living tissue, usually within a limited area.

  • necromancer
    One who conjures the spirits of the dead in order to magically reveal the future or influence the course of events.

  • necropolis
    A cemetery, especially a large, elaborate cemetery of an ancient city.

  • necropsy
    An autopsy, especially one performed on an animal.

PALEO

PALEO comes from the Greek palaios, meaning “ancient”—that is, “older than old.” The prefix sometimes gets attached to very recognizable words; paleobiology, for instance, deals with the biology of fossil organisms, paleogeography is the study of geography in earlier geological eras, and paleoecology is the study of the relationship of plants and animals to their environment in those eras.

  • Paleolithic Of or relating to the earliest period of the Stone Age, characterized by rough or chipped stone implements.

  • paleography
    1).The study of ancient writings and inscriptions.
    2).Ancient writings.

  • paleontology
    A science dealing with the life of past geological periods as known from fossil remains.

  • Paleozoic The era of geological history, ending about 248 million years ago, in which vertebrates and land plants first appeared.

CIRCU/CIRCUM

CIRCU/CIRCUM comes from the Latin circus, meaning “circle.” So a circus is traditionally held under a round tent. A circuit can be a tour around an area or territory, or the complete path of an electric current. To circumnavigate means “to navigate around”—often around the world.

  • circuitous
    1).Having a circular or winding course.
    2).Not forthright or direct in action.

2).The outer boundary or surface of a shape or object.

  • circumspect
    Careful to consider all circumstances and possible consequences; cautious.

  • circumvent
    1).To make a circuit around.
    2).To manage to get around, especially by clever means.

MINI/MINU

MINI/MINU come from Latin words meaning “small” and “least.” So the minimum is the least, and a minute amount is almost nothing. And mini- is all too familiar as a prefix that we’ve been applying to all kinds of things since the 1950s: minivan, miniskirt, mini-mart, minipark, and the rest.

  • minimalism
    A style or technique (as in music, literature, or design) that is characterized by extreme spareness and simplicity.

  • minuscule
    Very small.

  • minutiae
    Very small or minor details.

  • diminutive
    1).Indicating small size.
    2).Very small.

INTER

INTER comes straight from Latin. In English it has various meanings; all of them can be expressed broadly as “between,” but they’re still quite distinct: “moving between” (intercity), “communicating between” (intercom), “coming between” (intercept), and so on. No wonder so many English words begin with inter-.

  • intercede
    1).To act as a go-between between unfriendly parties.
    2).To beg or plead in behalf of another.

  • interstice
    A little space between two things; chink, crevice.

  • interdict
    1).To prohibit or forbid.
    2).To destroy, damage, or cut off (as an enemy line of supply) by firepower to stop or hamper an enemy.

  • interpolate
    To put something between other things or parts, especially to put words into a piece of writing or a conversation.

SUR

SUR is actually a shortening of the Latin prefix super-, meaning “over, above” (see SUPER), and has the same meaning. A surface is the face above or on the outside of something. A surplus is something above and beyond what is needed. And to survey a landscape is to look out over it.

  • surmount
    To rise above; overcome.

  • surcharge
    An additional tax or charge.

  • surfeit
    A supply that is more than enough; excess.

  • surreal
    Very strange or unusual; having the quality of a dream.

CO

CO is a Latin prefix that generally means “with, together,” and we see it daily in such words as costar, cofounder, co-owner, and coworker. But many other co- words aren’t quite so easy to understand when you first encounter them.

  • coalesce
    To come together to form one group or mass.

  • cogeneration
    The production of electricity using waste heat (as in steam) from an industrial process, or the use of steam from electric power generation as a source of heat.

SYN

SYN is a Greek and Latin prefix meaning “together” or “at the same time.” So “in sync” (short for “in synchronization”) means “together in time.” And a synonym is a word that can be considered together with another word since it has the same meaning.

  • syntax
    The way in which words are put together to form phrases, clauses, or sentences.

  • synthesize
    To make something by combining different things.

  • synergy
    The increased effectiveness that results when two or more people or businesses work together.

  • syndrome
    A group of signs and symptoms that occur together and characterize a particular abnormality or condition.

Words from Mythology and History

  • Adonis
    A very handsome young man.

  • amazon
    A tall, strong, often masculine woman.

  • chimera
    An often grotesque creature of the imagination.

  • cornucopia
    1).A container shaped like a hollow horn full of fruits, vegetables, and ears of grain.
    2).An abundance of something desirable.

  • Elysium
    A place or condition of ideal happiness; paradise.

  • epicure
    A person with cultivated taste, especially for food and drink; a gourmet.

  • exodus
    A situation in which many people leave a place at the same time.

  • gorgon
    An ugly, repulsive, or terrifying woman.

Unit 30

TOXI

TOXI comes from the Greek and Latin words for “poison,” something the Greeks and Romans knew a good deal about. Socrates died by taking a solution of poison hemlock, a flowering plant much like wild carrot that now also grows in the U.S. Rome’s enemy Mithridates, king of Pontus, was obsessed with poisons, experimented with them on prisoners, and tried to make himself immune to them by eating tiny amounts of them daily. Nero’s mother Agrippina poisoned several of her son’s rivals to power—and probably did the same to her own husband, the emperor Claudius.

  • toxin
    A substance produced by a living organism (such as bacteria) that is highly poisonous to other organisms.

  • toxicity
    The state of being poisonous; the degree to which something is poisonous.

  • toxicology
    A science that deals with poisons and their effect.

  • neurotoxin
    A poisonous protein that acts on the nervous system.

TEN/TENU

TEN/TENU comes from the Latin tenuis, meaning “thin.” So to extend something is to stretch it, and lots of things get thin when they’re stretched. The ten- root is even seen in pretend, which once meant to stretch something out above or in front; that something came to be a claim that you were something that you actually weren’t.

  • tenuous
    Having little substance or strength; flimsy, weak.

  • attenuated
    Thinned or weakened.

  • extenuating
    Partially excusing or justifying.

  • distended
    Stretched or bulging out in all directions; swelled.

TECHNI/TECHNO

TECHNI/TECHNO comes from the Greek techne, meaning “art, craft, skill,” and shows up in dozens of English words. Some, such as technical, technology, and technique, have long been familiar. Others, such as technothriller, were only coined in the current computer age, which has also seen the new cut-down terms techno (for techno-pop, the electronic dance music) and tech (for technician or technology).

  • technocrat
    A scientist or technical expert with power in politics or industry.

  • technophobe
    One who fears or dislikes advanced technology or complex devices and especially computers.

  • technophile
    One who loves technology.

  • pyrotechnic
    Of or relating to fireworks.

LONG

LONG comes from Latin longus, which, as you might guess, means “long.” The English word long shows up in many compound terms such as longsuffering (“patiently enduring lasting offense or hardship”) and long-winded (“boringly long in speaking or writing”), but the long- root also sometimes shows up less obviously. To prolong something is to lengthen it, for example, and a chaise longue (not lounge!) is “a long reclining chair.”

  • longitude
    Distance measured by degrees or time east or west from the prime meridian.

  • elongate
    1).To extend the length of; stretch.
    2).To grow in length.

  • longueur
    A dull and boring portion, as of a book.

  • oblong
    Longer in one direction than in the other.

IDIO

IDIO comes from the Greek idios, meaning “one’s own” or “private.” In Latin this root led to the word idiota, meaning “ignorant person”—that is, a person who doesn’t take in knowledge from outside himself. And that led to a familiar English word that gets used too often, usually to describe people who aren’t ignorant at all.

  • idiom
    An expression that cannot be understood from the meanings of its separate words but must be learned as a whole.

  • idiomatic
    In a manner conforming to the particular forms of a language.

  • idiosyncrasy
    An individual peculiarity of a person’s behavior or thinking.

  • idiopathic
    Arising spontaneously or from an obscure or unknown cause.

AER/AERO

AER/AERO comes from the Greek word for “air.” The aerospace industry manufactures vehicles that travel through the atmosphere and beyond into space. Aerodynamic designs move through the air with maximum speed. And aerophobia is the technical name for what we usually just call fear of flying.

  • aerial
    1).Performed in the air.
    2).Performed using an airplane.

  • aerate
    To supply with air or oxygen.

  • aerobic
    1).Living or occurring only in the presence of oxygen.
    2).Involving or increasing oxygen consumption.

  • anaerobic
    1).Living or occurring in the absence of oxygen.
    2).Relating to activity in which the body works temporarily with inadequate oxygen.

CAD

CAD comes from the Latin verb cadere, “to fall.” Thus, a cascade is usually a waterfall, but sometimes a flood of something else that seems to pour on top of you: a cascade of new problems, a cascade of honors, and so on.

  • cadaver
    A dead body, especially one that is to be dissected; a corpse.

  • decadent
    Marked by decay or decline, especially in morals.

  • cadence

  • tribute

    2).Something that proves the good quality or effectiveness of something.

  • tributary
    A stream flowing into a larger stream or a lake.

  • attribute
    1).To explain by indicating a cause.
    2).To regard as likely to be a quality of a person or thing.

  • retribution

HOM/HOMO comes from homos, the Greek word for “same,” which in English words may also mean “similar.” A homograph is a word spelled like another word but different in meaning or pronunciation, and a homosexual is a person who favors others of the same sex. (This root has nothing to do with the Latin homo, meaning “person,” as in Homo sapiens, the French homme, and the Spanish hombre.)

The original meaning can still be seen in a word like dissipate, which means “to break up and scatter.”

  • dissuade
    To convince (someone) not to do something.

The days leading up to Lent are known as the carnival season, from the Italian carnelevare, later shortened to carnevale, which meant “removal of meat”— though during carnival, of course, people indulge in just about everything, and the removal of meat only comes later.

CURR/CURS comes from currere, the Latin verb meaning “to run.” Although words based on this root don’t tend to suggest speed, the sense of movement remains.

The same verb actually gives us another root, vid-, as in Julius Caesar’s famous statement about his military exploits, “Veni, vidi, vici” (“I came, I saw, I conquered”), and such common English words as video.

    1).A distant view.
    2).An extensive mental view, as over a stretch of time.

    To have a mental picture of; visualize.

SPECT

SPECT comes from the Latin verb specere, meaning “to look at,” and produces several familiar English words. Spectacles can be glasses that you look through; but a spectacle can also be a remarkable sight—in Roman times, perhaps a spectacular chariot race or a spectacularly bloody battle between gladiators and wild beasts, mounted for the pleasure of its spectators.

  • aspect
    1).A part of something.
    2).A certain way in which something appears or may be regarded.

VOC

VOC comes from the Latin words meaning “voice” and “speak.” So a vocal ensemble is a singing group. A vocation was originally a “calling” from God to do religious work as a priest, monk, or nun, though today most people use the word just to mean a career. And a vocabulary is a set of words for speaking.

  • equivocate
    1).To use ambiguous language, especially in order to deceive.
    2).To avoid giving a direct answer.

  • irrevocable
    Impossible to call back or retract.

PHON

PHON is a Greek root meaning “sound,” “voice,” or “speech.” It’s probably most familiar in the form of the English suffix -phone, in words that begin with a Greek or Latin root as well. Thus, the tele- in telephone means “far,” the micro- in microphone means “small,” the xylo- in xylophone means “wood,” and so on.

  • phonics
    A method of teaching beginners to read and pronounce words by learning the characteristic sounds of letters, letter groups, and especially syllables.

PERI, in both Latin and Greek, means “around.” A period is often a span of time that keeps coming around regularly, day after day or year after year. With a periscope, you can see around corners. Peristalsis is the process that moves food around the intestines; without it, digestion would grind to a halt.

  • perimeter

  • sensor
    A device that detects a physical quantity (such as a movement or a beam of light) and responds by transmitting a signal.

    Cleverly deceptive reasoning or argument.

  • sophisticated
    1).Having a thorough knowledge of the ways of society.

PORT comes from the Latin verb portare, meaning “to carry.” Thus, something portable can be carried around. A porter carries your luggage, whether through a train station or high into the Himalayas. When we transport something, we have it carried from one place to another. And goods for export are carried away to another country.

Something extravagant, such as an extravaganza, goes way beyond the normal. And extra is naturally a word itself, a shortening of extraordinary, “beyond the ordinary.”

  • extradite

LUC

LUC comes from the Latin noun lux, “light,” and the verb lucere, “to shine or glitter.” In ancient Rome, Lucifer, meaning “Light-bearer,” was the name given to the morning star, but the name was eventually transferred by Christians to Satan. This tradition, which dates back to the period before Christ, said that Lucifer had once been among the angels but had wanted to be the great light in the sky, and for his pride had been cast out of heaven and thus became the opponent of everything good.

MOR/MORT comes from Latin words meaning “to die” and “death.” A mortuary is a place where dead bodies are kept until burial, and a postmortem examination is one conducted on a recently dead body. The Latin phrase “Memento mori” means “Remember that you must die”; so a memento mori is the name we give to a reminder of death; the skulls you can find carved on gravestones in old cemeteries are examples.

  • mortality

  • therefore
    certain to die.

COSM

COSM comes from the Greek word for “order.” Since the Greeks believed the universe was an orderly place, words in this group usually relate to the universe. So cosmonaut was the word for a space traveler from the former Soviet Union. (The roots of our own word, astronaut, suggest “star traveler” instead.) Oddly enough, cosmetics comes from the same root, since putting things in order is similar to decorating something—such as your face.

  • cosmos

    2).A place where things join: junction.

Unit 10

PUT

PUT comes from the Latin verb putare, meaning “to think, consider, or believe.” So, for example, a reputation is what others think of you. But when the root shows up in such words as compute, dispute, and deputy, its meaning is harder to trace.

  • reputed
    Believed to be a certain way by popular opinion.

  • disrepute
    Loss or lack of good reputation; disgrace.

  • impute
    To attribute.

LOG

LOG, from the Greek word logos, meaning “word,” “speech,” or “reason,” is found particularly in English words that end in -logy and -logue. The ending logy often means “the study of”; so, for instance, biology is the study of life, and anthropology is the study of humans. And -logue usually indicates a type of discussion; thus, dialogue is conversation between two people or groups, and an epilogue is an author’s last words on a subject. But exceptions aren’t hard to find.

MAR

MAR, from the Latin word mare, meaning “sea,” brings its salty tang to several English words. A submarine is an undersea ship. Marine means basically “relating to the sea,” so when the Continental Marines were established back in 1775, their job was to provide on-board security on naval ships; but they immediately began to be used on land as well, and the marines have continued to operate on both land and sea ever since.

  • marina
    A dock or harbor where pleasure boats can be moored securely, often with facilities offering supplies or repairs.

  • apathetic

In Scandinavia there’s a popular drink called aquavit, the name coming from the Latin aqua vitae, “water of life”—though instead of water it mostly consists of alcohol.

LINGU

LINGU comes from the Latin word that means both “tongue” and
“language,” and in English today tongue can still mean “language” (as in “her native tongue”). Our expression “slip of the tongue” is just a translation of the Latin phrase lapsus linguae. The root even shows up in a slangy-sounding word like lingo. And since lingu- changed to langu- in French, our word language is related as well.

  • lingua
    franca A language used as a common or commercial language among peoples who speak different languages.

Unit 12

UMBR

UMBR comes from the Latin umbra, meaning “shadow.” Thus, the familiar umbrella, with its ending meaning “little,” casts a “little shadow” to keep off the sun or the rain.

    2).A color that is greenish brown to dark reddish brown.

    A feeling of resentment at some slight or insult, often one that is imagined rather than real.

VEST

VEST comes from the Latin verb vestire, “to clothe” or “to dress,” and the noun vestis, “clothing” or “garment.” Vest is the shortest English word we have from this root, and is the name of a rather small piece of clothing.

THE/THEO

THE/THEO comes from the Greek word meaning “god.” Theology, the study of religion, is practiced by theologians. Monotheism is the worship of a single god; Christianity, Islam, and Judaism are monotheistic religions, and all three worship the same god. Polytheistic religions such as those of ancient Greece and Rome, on the other hand, worship many gods.

  • apotheosis
    1).Transformation into a god.
    2).The perfect example.

  • atheistic

  • theocracy
    1).Government by officials who are regarded as divinely inspired.
    2).A state governed by a theocracy.

ICON

ICON comes from the Greek eikon, which led to the Latin icon, both meaning “image.” Though the icon- root hasn’t produced many English words, the words that is does appear in tend to be interesting.

  • icon
    1).A religious image usually painted on a small wooden panel: idol.
    2).Emblem, symbol.

  • iconic
    1).Symbolic.
    2).Relating to a greatly admired and successful person or thing.

  • urbane
    Sophisticated and with polished manners.

  • exurban
    Relating to a region or settlement that lies outside a city and usually beyond its suburbs and often is inhabited chiefly by well-todo families.

  • subculture
    A group whose beliefs and behaviors are different from the main groups within a culture or society.

DEM/DEMO

DEM/DEMO comes from the Greek word meaning “people.” “Government by the people” was invented by the ancient Greeks, so it’s appropriate that they were the first to come up with a word for it: demokratia, or democracy.

  • demographic
    Having to do with the study of human populations, especially their size, growth, density, and patterns of living.

  • endemic
    1).Found only in a given place or region.

  • accord
    1).To grant.
    2).To be in harmony; agree.

  • concord
    1).A state of agreement: harmony.
    2).A formal agreement.

    To clear from accusations of fault or guilt.

  • inculpate
    To accuse or incriminate; to show evidence of someone’s involvement in a fault or crime.

    2).Clarity of speech.

GNI/GNO

GNI/GNO comes from a Greek and Latin verb meaning “to know,” and can be found at the root of know itself. Among other words built from this root, you may recognize (“know again”) some and be ignorant of (“not know”) others. But only an ignoramus would know absolutely none of them.

  • cognitive
    1).Having to do with the process of knowing, including awareness, judgment, and understanding.
    2).Based on factual knowledge that has been or can be gained by experience.

GRAPH

GRAPH comes from the Greek verb graphein, “to write.” Thus, a biography is a written account of someone’s life (see BIO), a discography is a written list of recordings on disc (records or CDs), and a filmography is a list of motion pictures. But lots of uses of -graph and -graphy don’t mean literally “writing” (as in autograph or paragraph), but instead something more like “recording,” as in photography, seismograph, or graph itself.

  • calligraphy
    The art of producing beautiful handwriting.

  • hagiography
    1).Biography of saints.
    2).Biography that idealizes or idolizes.

  • lithograph
    A picture made by printing from a flat surface (such as a smooth stone) prepared so that the ink will only stick to the design that will be printed.

ART

ART comes from the Latin word for “skill.” This reminds us that, until a few centuries ago, almost no one made a strong distinction between skilled craftsmanship and what we would now call “art.” And the word art itself could also mean simply “cleverness.” The result is that this root appears in some words where we might not expect it.

  • artful
    1).Skillful.
    2).Wily, crafty, sly.

  • artifact
    A usually simple object made by human workmanship, such as a tool or ornament, that represents a culture or a stage in a culture’s development.

  • artifice
    1).Clever skill.
    2).A clever trick.

    A skilled worker or craftsperson.

    To strengthen.

  • fortification
    1).The building of military defenses to protect a place against attack.
    2).A structure built to protect a place.

  • forte
    Something that a person does particularly well; one’s strong point.

  • fortitude
    Mental strength that allows one to face danger, pain, or hardship with courage.

    To cut out, especially surgically.

Unit 14

CRYPT

CRYPT comes from the Greek word for “hidden.” To encrypt a message is to encode it—that is, to hide its meaning in code language. When a scientific term begins with crypto-, it always means that there’s something hidden about it .

  • crypt
    1).A room completely or partly underground, especially under the main floor of a church.
    2).A room or area in a large aboveground tomb.

AB/ABS

AB/ABS comes to us from Latin, and means “from,” “away,” or “off.” Abuse is the use of something in the wrong way. To abduct is to “lead away from” or kidnap. Aberrant behavior is behavior that “wanders away from” what is acceptable. But there are so many words that include these roots that it would be absurd to try to list them all here.

  • abscond
    To depart in secret and hide.

  • abstemious
    Restrained, especially in the consumption of food or alcohol.

  • abstraction
    The consideration of a thing or idea without associating it with a particular example.

  • abstruse
    Hard to understand; deep or complex.

PED-

PED- comes from the Greek word for “child.” The same root also has the meaning “foot” (see PED), but in English words it usually isn’t hard to tell the two apart.

  • pedagogy
    The art, science, or profession of teaching.

  • pedant
    1).A formal, unimaginative teacher.
    2).A person who shows off his or her learning.

TROP comes from the Greek tropos, meaning “turn” or “change.” The troposphere is the level of the atmosphere where most weather changes—or “turns in the weather”—occur. And the Tropics of Cancer and Capricorn are the lines of latitude where the sun is directly overhead when it reaches its northernmost and southernmost points, on about June 22 and December 22 every year—that is, the point where it seems to turn and go back the other way.

  • heliotrope
    Any of a genus of herbs or shrubs having small white or purple flowers.

  • psychotropic
    Acting on the mind.

NEO

NEO comes from the Greek neos, meaning “new.” Neo- has become a part of many English words. Some are easy to understand; for example, neo-Nazi. Some are less so; you might not immediately guess that neotropical means
“from the tropics of the New World,” or that a neophyte is a “newcomer.” When William Ramsay discovered four new gases, he named them all using Greek roots that at first glance might sound slightly mysterious: argon (“idle”), krypton (“hidden”), xenon (“strange”)—and neon (“new”).

  • neoclassic
    Relating to a revival or adaptation of the styles of ancient Greece and Roman, especially in music, art, or architecture.

  • neoconservative
    A conservative who favors strongly encouraging democracy and the U.S. national interest in world affairs, including through military means.

The long-running PBS show Nova keeps its large audience up to date on what’s new in the world of science. And when the British king sent Scottish settlers to a large island off Canada’s Atlantic coast in the 17th century, he named it Nova Scotia, or “New Scotland.”

TEN

TEN, from the Latin verb tenere, basically means “hold” or “hold on to.” A tenant is the “holder” of an apartment, house, or land, but not necessarily the owner. A lieutenant governor may “hold the position” ( “serve in lieu”) of the governor when necessary.

  • tenure
    1).The amount of time that a person holds a job, office, or title.

Unit 15

TERM/TERMIN

TERM/TERMIN comes from the Latin verb terminare, “to limit, bound, or set limits to,” and the noun terminus, “limit or boundary.” In English, those boundaries or limits tend to be final. A term goes on for a given amount of time and then ends, and to terminate a sentence or a meeting or a ballgame means to end it.

  • terminal
    1).Forming or relating to an end or limit.
    2).Fatal.

    Not precisely determined; vague.

  • geothermal
    Of, relating to, or using the natural heat produced inside the Earth.

SPHER comes from the Greek word for “ball.” A ball is itself a sphere, as is the ball that we call Earth. So is the atmosphere, and so are several other invisible “spheres” that encircle the Earth.

  • spherical
    Relating to a sphere; shaped like a sphere or one of its segments.

  • stratosphere
    1).The part of the earth’s atmosphere that extends from about seven to about 30 miles above the surface.

  • amorphous
    Without a definite shape or form; shapeless.

  • anthropomorphic

DOC/DOCT

DOC/DOCT comes from the Latin docere, which means “to teach.” So, for instance, a doctor was originally a highly educated person capable of instructing others in a field—which usually wasn’t medicine.

    1).Something that is taught.
    2).An official principle, opinion, or belief.

  • docent

  • tutorial
    1).A class for one student or a small group of students.

DI/DUP, Greek and Latin prefixes meaning “two,” show up in both technical and nontechnical terms, with dup- sometimes shortened to du-. So a duel is a battle between two people. A duet is music for a duo, or pair of musicians. A duplicate is an exact copy, or twin. And if you have dual citizenship, you belong to two countries at once.

Unit 16

TOP

TOP comes from topos, the Greek word for “place.” A topic is a subject rather than a place; to the Greeks, the original word meant more or less “about one place or subject (rather than another)”—which just goes to show that it’s not always easy to trace a word’s meaning from its roots.

  • topical
    1).Designed for local application to or treatment of a bodily part.
    2).Referring to the topics of the day.

  • ectopic
    Occurring or originating in an abnormal place.

  • utopian

CENTR/CENTER

CENTR/CENTER comes from the Greek kentron and the Latin centrum, meaning “sharp point” or “center point of a circle.” A centrifuge is a spinning machine that throws things outward from the center; the apparent force that pushes them outward is called centrifugal force.

  • eccentric
    1).Not following an established or usual style or conduct.
    2).Straying from a circular path; off-center.

  • epicenter
    1).The location on the earth’s surface directly above the focus of an earthquake.

  • ethnocentric
    Marked by or based on the attitude that one’s own group is superior to others.

DOM

DOM comes from the Latin domus, “house,” and dominus, “master,” and the two are indeed related. In the Bible, King Ahasuerus, angered by his queen’s disobedience, proclaims that “every man is to be master of his own house,” and in the Roman empire no one doubted that this was how it was meant to be. A domain is the area where a person has authority or is dominant—but we no longer think of a house as the domain of a single dominant member of a family.

  • dominion
    1).An area over which one rules; domain.
    2).Supreme authority.

  • predominant
    Greater in importance, strength, influence, or authority.

    Tending to control the behavior of others in a bossy manner.

  • domination
    1).Supremacy or power over another.

OMNI

OMNI comes from the Latin word omnis, meaning “all.” So in English words, omni- can mean “in all ways,” “in all places,” or “without limits.” An omnidirectional antenna, for example, is one that receives or sends radio waves equally well in all directions. And Omni by itself has been used repeatedly as a brand name for things as different as a hotel chain and a science magazine.

  • omnivore
    An animal that eats both plants and other animals.

  • omnipotent
    Having complete or unlimited power; allpowerful.

  • omnibus
    Of or including many things.

  • omniscient
    Knowing everything; having unlimited understanding or knowledge.

HOL/HOLO

HOL/HOLO, meaning “whole,” comes from the Greek word holos, with the same meaning. The root can be found in catholic. When capitalized, Catholic refers to the worldwide Christian church based in Rome, which was once the “whole”—that is, the only—Christian church.

    1).Able to be dissolved in a liquid, especially water.
    2).Able to be solved or explained.

  • absolution
    The act of forgiving someone for their sins.

  • dissolution
    The act or process of breaking down or apart into basic components, as through disruption or decay.

  • resolute
    Marked by firm determination.

HYDR

HYDR flows from the Greek word for “water.” The “water” root can be found in the lovely flower called the hydrangea: its seed capsules resemble ancient Greek water vessels.

  • hydraulic
    1).Relating to water; operated, moved, or brought about by means of water.
    2).Operated by the resistance or pressure of liquid forced through a small opening or tube.

  • dehydrate
    1).To remove water from.
    2).To deprive of energy and zest.

  • hydroelectric
    Having to do with the production of electricity by waterpower.

  • hydroponics
    The growing of plants in nutrient solutions, with or without supporting substances such as sand or gravel.

Unit 26

MUR

MUR, from the Latin noun murus, meaning “wall,” has produced a modest number of English words.

  • muralist
    A painter of wall paintings.

  • intramural
    Existing or occurring within the bounds of an institution, especially a school.

  • extramural
    Existing outside or beyond the walls or boundaries of an organized unit such as a school or hospital.

  • immure
    To enclose within, or as if within, walls; imprison.

POLIS/POLIT

POLIS/POLITcomes from the Greek word for “city.” The ancient Greek city-states, such as Athens, Thebes, and Sparta, operated much like separate nations, so all their politics was local, like all their public policy—and even all their police!

  • politic
    1).Cleverly tactful.
    2).Wise in promoting a plan or plan of action.

  • politicize
    To give a political tone or character to.

  • acropolis
    The high, fortified part of a city, especially an ancient Greek city.

  • megalopolis
    1).A very large city.
    2).A thickly populated area that includes one or more cities with the surrounding suburbs.

NUMER

NUMER comes from the Latin words meaning “number” and “to count.” A numeral is the symbol that represents a number. Numerous means “many,” and innumerable means “countless.” Numerical superiority is superiority in numbers, and your numerical standing in a class is a ranking expressed as a number.

  • numerology
    The study of the occult significance of numbers.

  • alphanumeric
    Having or using both letters and numbers.

  • enumerate
    To specify one after another; list.

  • supernumerary
    Exceeding the usual number.

KILO

KILO is the French version of the Greek word chilioi, meaning “thousand.” France is also where the metric system originated, in the years following the French Revolution. So in English, kilo- shows up chiefly in metric-system units. Before the computer age, the most familiar kilo- words for Englishspeakers were probably kilowatt, meaning “1,000 watts,” and kilowatt-hour, meaning the amount of energy equal to one kilowatt over the course of an hour.

  • kilobyte
    A unit of computer information equal to 1,024 bytes.

  • kilometer
    A unit of length equal to 1,000 meters.

  • kilohertz
    A unit of frequency equal to 1,000 cycles per second.

  • kilogram
    A unit of weight equal to 1,000 grams.

MICRO

MICRO, from the Greek mikros, meaning “small,” is a popular English prefix. A microscope lets the eye see microscopic objects, and libraries store the pages of old newspapers on microfilm at 1/400th of their original size. And we continue to attach micro- to lots of familiar words; most of us could figure out the meaning of microbus and microquake without ever having heard them before. Scientists often use micro- to mean “millionth”; thus, a microsecond is a millionth of a second, and a micrometer is a millionth of a meter.

  • microbe
    An organism (such as a bacterium) of microscopic or less than microscopic size.

  • microbiologist
    A scientist who studies extremely small forms of life, such as bacteria and viruses.

  • microbrew
    A beer made by a brewery that makes beer in small amounts.

  • microclimate
    The essentially uniform local climate of a small site or habitat.

  • multicellular
    Consisting of many cells.

  • multidisciplinary
    Involving two or more subject areas.

  • multifarious
    Having or occurring in great variety; diverse.

  • multilateral
    Involving more than two nations or parties.

PAR

PAR, from the Latin, means “equal.” Our English word par means an amount taken as an average or a standard, and especially the standard score for each hole on a golf course—which is why the phrase “par for the course” means “about as well as expected.” We compare things to see if they’re equal; similar things can be called comparable—that is, “equal with.” And “on a par with” means “comparable to.”

  • parity
    The state of being equal.

  • disparity
    A noticeable and often unfair difference between people or things.

  • nonpareil
    Someone or something of unequaled excellence.

  • subpar
    Below a usual or normal level.

PHOB

PHOB comes from the Greek noun phobos, “fear,” and it shows up clearly in our noun phobia, meaning “unusual fear of a specific thing.” Phobias vary greatly in seriousness and also in frequency. Most of us have experienced claustrophobia at some time, but few truly suffer from fear of the number 13, a condition known as triskaidekaphobia.

  • acrophobic
    Fearful of heights.

  • agoraphobia
    A fear of being in embarrassing or inescapable situations, especially in open or public places.

  • xenophobe
    One who has a fear or hatred of strangers or foreigners.

  • arachnophobia
    Having a fear or dislike of spiders.

HEM/HEMO

HEM/HEMO comes from the Greek word for “blood” and is found at the beginning of many medical terms. By dropping the h-, the same word produced the suffix -emia, which likewise shows up in lots of “blood” words, including anemia, leukemia and hyperglycemia.

  • hemorrhage
    1).A large loss of blood from a blood vessel.
    2).A rapid and uncontrollable loss or outflow.

  • hematology
    The study of blood and blood-forming organs.

  • hemophilia
    A bleeding disorder caused by the blood’s inability to coagulate.

  • hemoglobin
    The element in blood that transports oxygen from the lungs to the body’s tissues and transports carbon dioxide from the tissues back to the lungs.

ITIS

ITIS, a suffix found in both Greek and Latin, means “disease” or “inflammation.” In appendicitis your appendix is swollen and painful, and in tonsillitis the same is true of your tonsils. With laryngitis, your throat and larynx may become so sore that it’s difficult to talk. Some of us enjoy making up our own -itis words; high-school teachers, for example, long ago noticed that many of their seniors tended to lose all interest in schoolwork and start skipping classes, and labeled the condition senioritis.

  • bursitis
    Inflammation of a lubricating sac (bursa), especially of the shoulder or elbow.

  • hepatitis
    Inflammation of the liver.

  • bronchitis
    Inflammation of the bronchial tubes.

  • tendinitis
    A painful condition in which a tendon in the arm or leg becomes inflamed.

Unit 27

NANO

NANO comes from the Greek nanos, meaning “dwarf.” For a prefix meaning “small,” English got by for centuries with the Greek micro-, and later minicame to be used widely as well. But only recently, as a result of advances in scientific knowledge and technology, has there been a need for a prefix meaning “extremely small”—a need that’s been filled by nano-, which today is being attached to all kinds of words, sometimes not very seriously (nanoskirt, nano-brained, etc.).

  • nanotechnology
    The science of manipulating materials on an atomic or molecular scale, especially to build microscopic devices such as robots.

  • nanosecond
    One billionth of a second.

  • nanostructure
    An arrangement, structure, or part of something of molecular dimensions.

  • nanoparticle
    A tiny particle whose size is measured in billionths of a meter.

SUPER

SUPER, a Latin prefix meaning “over, higher, more than,” has become one of the most familiar prefixes in English, one of those prefixes that we use to create new words all the time: supermodel, superpowerful, superjock, supersize, supersweet—the list goes on and on. This all seems to have started in 1903 when the playwright G. B. Shaw translated the German word

  • superfluous
    Beyond what is needed; extra.

  • insuperable
    Incapable of being solved or overcome.

  • supersede
    To take the place of; to replace with something newer or more useful.

  • superlative
    Supreme, excellent.

DE

DE in Latin means “down, away.” So a descent is a downward slope or climb, and a decline is a downward slide (of health, income, etc.). To devalue something is to take value away from it. And you might describe a depressed friend as “down.”

  • debase
    To lower the value or reputation of someone or something.

  • defamation
    The harming of someone’s reputation by libel or slander.

  • degenerative
    Causing the body or part of the body to become weaker or less able to function as time passes.

  • dejection
    Sadness, depression, or lowness of spirits.

NUL/NULL

NUL/NULL comes from the Latin word nullus, “none,” which is itself a combination of ne- (“not”) and ullus (“any”). Have you ever noticed how many of our negative words start with n-

  • null
    1).Having no legal power; invalid.
    2).Having no elements.

  • nullity
    1).Nothingness.
    2).A mere nothing.

  • nullify
    1).To cancel legally.
    2).To cause something to lose its value or to have no effect.

  • annulment
    An official statement that something is no longer valid.

  • armada
    A large group of warships or boats.

  • armistice
    An agreement to stop fighting a war; a truce.

  • armory
    A place where weapons are made or stored.

  • disarming
    Tending to remove any feelings of unfriendliness or distrust.

  • upsurge
    A rapid or sudden increase or rise.

  • insurgency
    A usually violent attempt to take control of a government; a rebellion or uprising.

  • counterinsurgent
    A person taking military or political action against guerrillas or revolutionaries.

  • resurgent
    Rising again into life, activity, or prominence.

STRAT

STRAT comes from the Latin word stratum, meaning “spread” or “bed.” Strata, a form of the same word, came to be used by the Romans to mean “paved road”—that is, street.

  • stratum
    1).A layer of a substance, especially one of a series of layers.
    2).A level of society made up of people of the same rank or position.

  • stratification
    The process or state of being formed, deposited, or arranged in layers.

  • substrate
    1).An underlying layer.
    2).The base on which an organism lives.

  • stratocumulus
    A low-lying cloud formation appearing as extensive and often dark horizontal layers, with tops rounded into large balls or rolls.

LATER

LATER comes from the Latin adjective lateralis, meaning “side.” The noun for “side” in Latin was latus, and the same word served as an adjective meaning “wide.” The relationship between the two isn’t hard to spot, since something wide extends far out to its sides. So lines of latitude extend eastwest around the earth, in the dimension we tend to think of as its width (unlike lines of longitude, which extend north-south, in the dimension that, for some reason, we decided to think of as its “length”).

  • lateral
    Of or relating to the side.

  • bilateral
    Involving two groups or countries.

  • collateral
    1).Associated but of secondary importance.
    2).Related but not in a direct or close way.

  • equilateral
    Having all sides or faces equal.

TOM

TOM comes from the Greek root meaning “cut.” Thus, the Latin word anatomia, from which we get anatomy, means “dissection”—that is cutting or separating the parts of an organism for detailed examination. In a lobotomy, the nerves linking a brain lobe to the rest of the brain are removed; even though lobotomies have hardly been performed in the last 50 years, the idea can still fill us with horror.

  • appendectomy
    Surgical removal of the human appendix.

  • gastrectomy
    Surgical removal of all or part of the stomach.

  • tonsillectomy
    Surgical removal of the tonsils.

  • mastectomy
    Surgical removal of all or part of the breast.

IATR

IATR, from the Greek iatros, “healer, physician,” usually hides in the middle of words, where it isn’t immediately noticed. A pediatrician treats children (see PED-). A psychiatrist is a physician who treats mental problems. (A psychologist, by contrast, doesn’t have a medical degree and thus can’t prescribe drugs.) And a physiatrist is a doctor who practices “physical medicine and rehabilitation,” which may involve such things as testing various physical abilities, relieving pain through electric heat or massage, or training patients to exercise or to use an artificial limb.

  • iatrogenic
    Caused accidentally by medical treatment.

  • bariatric
    Relating to or specializing in the treatment of obesity.

  • geriatric
    Of or relating to old people.

  • podiatrist
    A doctor who treats injuries and diseases of the foot.

Unit 28

MEDI

MEDI comes from the Latin medius, meaning “middle.” Our word medium refers to something in a middle position. The medieval period of European history, also known as the Middle Ages, is the period between Greek and Roman antiquity and the “modern age.” But why people around 1620 began to use the term “Middle Ages,” because they regarded themselves as modern, is an interesting question.

  • median
    In the middle; especially, having a value that is in the middle of a series of values arranged from smallest to largest.

  • mediate
    1).To work with opposing sides in an argument or dispute in order to get an agreement.
    2).To achieve a settlement or agreement by working with the opposing sides.

  • intermediary
    A person who works with opposing sides in a dispute in order to bring about an agreement.

  • mediocrity
    The quality of being not very good.

OID

OID comes from the Greek word for “appearance” or “form.” Since aster in ancient Greek meant “star,” the small bodies orbiting between Mars and Jupiter that looked like stars through primitive telescopes were called asteroids. A factoid is a little bit of information that looks like a fact, whether it is or not. And some people these days will attach -oid to just about anything; you can probably figure out the meaning of nutsoid, nerdoid, and freakazoid without much help.

  • rhomboid
    In geometry, a shape with four sides where only the opposite sides and angles are equal.

  • deltoid
    A large muscle of the shoulder.

  • humanoid
    Looking or acting like a human.

SCOP

SCOP, which usually appears in a suffix, comes from the Greek skopein, meaning “to look at.” In English we have the simple noun scope, along with some other words it sometimes stands for: telescope, microscope, periscope, and so on. And have you ever used a stereoscope, a device your greatgrandparents probably enjoyed, which lets you look through a viewer at two slightly different photographs of the same thing, one with each eye, to enjoy the illusion that you’re seeing it in three dimensions

  • endoscope
    A lighted tubular medical instrument for viewing the interior or a hollow organ or body part that typically has one or more channels to permit passage of surgical instruments.

  • arthroscopic
    Relating to a fiber-optic instrument that is inserted through an incision near a joint to examine the joint’s interior.

  • laparoscopy
    Examination of the interior of the abdomen using a fiber-optic instrument inserted through a cut in the abdomen’s wall.

  • oscilloscope
    An instrument that shows visual images of changing electrical current on a screen.

TRANS

TRANS comes from Latin to indicate movement “through, across, or beyond” something. Translation carries a writer’s meaning from one language to another. A television signal is sent or transmitted through the air (or a cable) to your set. When making your way through a city on public transportation, you may have to transfer from one bus or subway to another.

  • transient
    1).Not lasting long; short-lived.
    2).Passing through a place and staying only briefly.

  • transfiguration
    A change in form or appearance; a glorifying spiritual change.

  • transponder
    A radio or radar set that emits a radio signal after receiving such a signal.

  • transcendent
    1).Exceeding or rising above usual limits;
    supreme.
    2).Beyond comprehension; beyond ordinary experience or material existence.

PRO

PRO is an important prefix, with a couple of quite different broad meanings. In this section, we’ll look at words in which pro- has the basic meaning “for” or “favoring.” Everyone knows words like pro-democracy and pro-American, but other pro- words may not be quite so self-explanatory.

  • proactive
    Acting in anticipation of future problems, needs, or changes.

  • pro
    bono Being, involved in, or doing professional work, and especially legal work, donated for the public good.

  • proponent
    One who argues in favor of something: advocate.

  • pro
    forma Done or existing as something that is required but that has little true meaning or importance.

  • protrude
    To jut out from the surrounding surface or context.

  • prophylaxis
    Measures designed to preserve health and prevent the spread of disease.

  • promulgate
    1).To proclaim or make public.
    2).To put (a law) into effect.

  • prologue
    1).An introduction to a literary work.
    2).An introductory event or development.

RE

RE is a prefix which, like pro- (see PRO), has more than one meaning. In this section, we’ll focus on the meaning “again.” We use re- words with this meaning every day—redo, reheat, recheck, reread, resell, repaint, etc.—and we feel free to make up new ones as needed. But in plenty of other re- words, the meaning isn’t so obvious.

  • remorse
    A deep regret arising from a sense of guilt for past wrongs.

  • reiterate
    To state or do over again or repeatedly.

  • rejuvenate
    To make young or youthful again; to give new vigor to.

  • reconcile
    1).To make agree.
    2).To make friendly again.

RE-

RE-, in its other main sense, means “back” or backward." Since doing something again means going back to it, the two senses are actually related; still, the meaning of re- in most words is pretty clearly one or the other. So a rebound comes back at you; to recall means to “call back” a memory; and to react is to “act back” at someone else’s action.

  • reciprocal
    1).Done, given, or felt equally by both sides.
    2).Related to each other in such a way that one completes the other or is the equal of the other.

  • rebut
    1).To oppose by argument.
    2).To prove to be wrong.

  • revoke
    To officially cancel the power or effect of something (such as a law, order, or privilege).

  • regress
    To return to an earlier and usually worse or less developed condition or state.

DERM

DERM comes from the Greek derma, meaning “skin.” For medical advice on a skin problem such as acne, we may go to a dermatologist, or skin specialist. When we get a shot, it’s usually with a hypodermic, a needle that goes “under the skin” (see HYP/HYPO). A pachyderm is a “thick-skinned” animal, which most of us just call an elephant.

  • dermal
    Relating to the skin and especially to the dermis.

  • epidermis
    The outer layer of the skin.

  • taxidermist
    One who prepares, stuffs, and mounts the skins of dead animals.

  • dermatitis
    Inflammation of the skin.

ENDO

ENDO comes from the Greek endon, meaning “within.” In English it appears almost always in scientific terms, especially in biology. A nonscientific endoword is endogamy, meaning marriage within a specific group as required by custom or law—one of the many customs that can be seen everywhere from the most remote tribes to the highest society in wealthy countries.

  • endocrine
    1).A hormone.
    2).Any of several glands (such as the thyroid) that pour their secretions directly into the blood or lymph.

  • endogenous
    Developing or originating within a cell, organ, body, or system.

  • endorphin
    Any of a group of proteins in the brain that are able to relieve pain.

Unit 29

NECRO

NECRO comes from the Greek nekros, meaning “dead body,” so it’s not surprising that it shows up in some unappetizing places. A necrophagous insect, for instance, is one that feeds on dead bodies; when homicide investigators discover a corpse, they may use the insect evidence to figure out when the person died.

  • necrosis
    Death of living tissue, usually within a limited area.

  • necromancer
    One who conjures the spirits of the dead in order to magically reveal the future or influence the course of events.

  • necropolis
    A cemetery, especially a large, elaborate cemetery of an ancient city.

  • necropsy
    An autopsy, especially one performed on an animal.

PALEO

PALEO comes from the Greek palaios, meaning “ancient”—that is, “older than old.” The prefix sometimes gets attached to very recognizable words; paleobiology, for instance, deals with the biology of fossil organisms, paleogeography is the study of geography in earlier geological eras, and paleoecology is the study of the relationship of plants and animals to their environment in those eras.

  • Paleolithic Of or relating to the earliest period of the Stone Age, characterized by rough or chipped stone implements.

  • paleography
    1).The study of ancient writings and inscriptions.
    2).Ancient writings.

  • paleontology
    A science dealing with the life of past geological periods as known from fossil remains.

  • Paleozoic The era of geological history, ending about 248 million years ago, in which vertebrates and land plants first appeared.

CIRCU/CIRCUM

CIRCU/CIRCUM comes from the Latin circus, meaning “circle.” So a circus is traditionally held under a round tent. A circuit can be a tour around an area or territory, or the complete path of an electric current. To circumnavigate means “to navigate around”—often around the world.

  • circuitous
    1).Having a circular or winding course.
    2).Not forthright or direct in action.

2).The outer boundary or surface of a shape or object.

  • circumspect
    Careful to consider all circumstances and possible consequences; cautious.

  • circumvent
    1).To make a circuit around.
    2).To manage to get around, especially by clever means.

MINI/MINU

MINI/MINU come from Latin words meaning “small” and “least.” So the minimum is the least, and a minute amount is almost nothing. And mini- is all too familiar as a prefix that we’ve been applying to all kinds of things since the 1950s: minivan, miniskirt, mini-mart, minipark, and the rest.

  • minimalism
    A style or technique (as in music, literature, or design) that is characterized by extreme spareness and simplicity.

  • minuscule
    Very small.

  • minutiae
    Very small or minor details.

  • diminutive
    1).Indicating small size.
    2).Very small.

INTER

INTER comes straight from Latin. In English it has various meanings; all of them can be expressed broadly as “between,” but they’re still quite distinct: “moving between” (intercity), “communicating between” (intercom), “coming between” (intercept), and so on. No wonder so many English words begin with inter-.

  • intercede
    1).To act as a go-between between unfriendly parties.
    2).To beg or plead in behalf of another.

  • interstice
    A little space between two things; chink, crevice.

  • interdict
    1).To prohibit or forbid.
    2).To destroy, damage, or cut off (as an enemy line of supply) by firepower to stop or hamper an enemy.

  • interpolate
    To put something between other things or parts, especially to put words into a piece of writing or a conversation.

SUR

SUR is actually a shortening of the Latin prefix super-, meaning “over, above” (see SUPER), and has the same meaning. A surface is the face above or on the outside of something. A surplus is something above and beyond what is needed. And to survey a landscape is to look out over it.

  • surmount
    To rise above; overcome.

  • surcharge
    An additional tax or charge.

  • surfeit
    A supply that is more than enough; excess.

  • surreal
    Very strange or unusual; having the quality of a dream.

CO

CO is a Latin prefix that generally means “with, together,” and we see it daily in such words as costar, cofounder, co-owner, and coworker. But many other co- words aren’t quite so easy to understand when you first encounter them.

  • coalesce
    To come together to form one group or mass.

  • cogeneration
    The production of electricity using waste heat (as in steam) from an industrial process, or the use of steam from electric power generation as a source of heat.

SYN

SYN is a Greek and Latin prefix meaning “together” or “at the same time.” So “in sync” (short for “in synchronization”) means “together in time.” And a synonym is a word that can be considered together with another word since it has the same meaning.

  • syntax
    The way in which words are put together to form phrases, clauses, or sentences.

  • synthesize
    To make something by combining different things.

  • synergy
    The increased effectiveness that results when two or more people or businesses work together.

  • syndrome
    A group of signs and symptoms that occur together and characterize a particular abnormality or condition.

Words from Mythology and History

  • Adonis
    A very handsome young man.

  • amazon
    A tall, strong, often masculine woman.

  • chimera
    An often grotesque creature of the imagination.

  • cornucopia
    1).A container shaped like a hollow horn full of fruits, vegetables, and ears of grain.
    2).An abundance of something desirable.

  • Elysium
    A place or condition of ideal happiness; paradise.

  • epicure
    A person with cultivated taste, especially for food and drink; a gourmet.

  • exodus
    A situation in which many people leave a place at the same time.

  • gorgon
    An ugly, repulsive, or terrifying woman.

Unit 30

TOXI

TOXI comes from the Greek and Latin words for “poison,” something the Greeks and Romans knew a good deal about. Socrates died by taking a solution of poison hemlock, a flowering plant much like wild carrot that now also grows in the U.S. Rome’s enemy Mithridates, king of Pontus, was obsessed with poisons, experimented with them on prisoners, and tried to make himself immune to them by eating tiny amounts of them daily. Nero’s mother Agrippina poisoned several of her son’s rivals to power—and probably did the same to her own husband, the emperor Claudius.

  • toxin
    A substance produced by a living organism (such as bacteria) that is highly poisonous to other organisms.

  • toxicity
    The state of being poisonous; the degree to which something is poisonous.

  • toxicology
    A science that deals with poisons and their effect.

  • neurotoxin
    A poisonous protein that acts on the nervous system.

TEN/TENU

TEN/TENU comes from the Latin tenuis, meaning “thin.” So to extend something is to stretch it, and lots of things get thin when they’re stretched. The ten- root is even seen in pretend, which once meant to stretch something out above or in front; that something came to be a claim that you were something that you actually weren’t.

  • tenuous
    Having little substance or strength; flimsy, weak.

  • attenuated
    Thinned or weakened.

  • extenuating
    Partially excusing or justifying.

  • distended
    Stretched or bulging out in all directions; swelled.

TECHNI/TECHNO

TECHNI/TECHNO comes from the Greek techne, meaning “art, craft, skill,” and shows up in dozens of English words. Some, such as technical, technology, and technique, have long been familiar. Others, such as technothriller, were only coined in the current computer age, which has also seen the new cut-down terms techno (for techno-pop, the electronic dance music) and tech (for technician or technology).

  • technocrat
    A scientist or technical expert with power in politics or industry.

  • technophobe
    One who fears or dislikes advanced technology or complex devices and especially computers.

  • technophile
    One who loves technology.

  • pyrotechnic

LONG

LONG comes from Latin longus, which, as you might guess, means “long.” The English word long shows up in many compound terms such as longsuffering (“patiently enduring lasting offense or hardship”) and long-winded (“boringly long in speaking or writing”), but the long- root also sometimes shows up less obviously. To prolong something is to lengthen it, for example, and a chaise longue (not lounge!) is “a long reclining chair.”

  • longitude
    Distance measured by degrees or time east or west from the prime meridian.

  • elongate
    1).To extend the length of; stretch.
    2).To grow in length.

  • longueur
    A dull and boring portion, as of a book.

  • oblong
    Longer in one direction than in the other.

IDIO

IDIO comes from the Greek idios, meaning “one’s own” or “private.” In Latin this root led to the word idiota, meaning “ignorant person”—that is, a person who doesn’t take in knowledge from outside himself. And that led to a familiar English word that gets used too often, usually to describe people who aren’t ignorant at all.

  • idiom
    An expression that cannot be understood from the meanings of its separate words but must be learned as a whole.

  • idiomatic
    In a manner conforming to the particular forms of a language.

  • idiosyncrasy
    An individual peculiarity of a person’s behavior or thinking.

  • idiopathic
    Arising spontaneously or from an obscure or unknown cause.

AER/AERO

AER/AERO comes from the Greek word for “air.” The aerospace industry manufactures vehicles that travel through the atmosphere and beyond into space. Aerodynamic designs move through the air with maximum speed. And aerophobia is the technical name for what we usually just call fear of flying.

  • aerial
    1).Performed in the air.
    2).Performed using an airplane.

  • aerate
    To supply with air or oxygen.

  • aerobic
    1).Living or occurring only in the presence of oxygen.
    2).Involving or increasing oxygen consumption.

  • anaerobic
    1).Living or occurring in the absence of oxygen.
    2).Relating to activity in which the body works temporarily with inadequate oxygen.

CAD

CAD comes from the Latin verb cadere, “to fall.” Thus, a cascade is usually a waterfall, but sometimes a flood of something else that seems to pour on top of you: a cascade of new problems, a cascade of honors, and so on.

  • cadaver
    A dead body, especially one that is to be dissected; a corpse.

  • decadent
    Marked by decay or decline, especially in morals.

  • cadence
    1).The close of a musical phrase, especially one that moves to a harmonic point of rest.

    2).Something that proves the good quality or effectiveness of something.

  • tributary
    A stream flowing into a larger stream or a lake.

    1).To explain by indicating a cause.
    2).To regard as likely to be a quality of a person or thing.
