Unit 12 · Words: Stems and Meaning

Look at the word transportation. It looks long, but it is built from three pieces. In the middle sits port, which comes from a Latin word meaning carry. In front is trans, meaning across. At the end is ation, which turns an action into a thing. Put the pieces together: the act of carrying something across. A bus, a train and a bike lane are all transportation.

The piece in the middle is the stem. Some teachers call it the root. A stem carries the main meaning of the word, but most stems from Greek and Latin cannot stand alone. Port is not an English word by itself in this sense; you do not port your books to school. It needs company. A prefix attaches to the front of a stem and changes its meaning. A suffix attaches to the end and often changes the word’s job, turning a verb into a noun or an adjective.

Try it with the stem dict, from a Latin word meaning say. Add the prefix pre, meaning before, and you get predict: to say before it happens. Add the suffix ion and you get prediction, the thing you said. Swap in the prefix contra, meaning against, and you get contradict: to say the opposite of what someone else said. Same stem, three different words, and you can read all three.

Here is the habit to build. When a long word stops you, do not guess from the first letter. Find the stem in the middle first. Ask what it means. Then look at the front and the back for a prefix and a suffix. Say the parts out loud. Most of the time the meaning will fall into place, just as it did for Marisol on her biology test.

English is a mix. Its everyday words, like house, bread, sun and run, mostly come from old Germanic roots. But when the Normans conquered England in 1066, French became the language of the court and the law for centuries. French grew out of Latin, so thousands of Latin words poured into English: justice, nation, port, credit. Later, scholars borrowed straight from Latin books.

Greek came in a different door. When scientists in the 1600s, 1700s and 1800s needed names for new things, they often built them from Greek parts. Telephone, photograph, biology, microscope and thermometer were all made this way, out of pieces that Greek speakers had used two thousand years earlier. That is why so many science and medical words feel Greek. They are.

You can often tell which family a stem belongs to. Latin stems tend to show up in law, government and everyday formal words: dict, port, cred, ject, rupt, spec, bene, mal. Greek stems crowd into science and technology: bio, geo, graph, log, chron, phon, tele, micro, poly, hydro, auto, anti. The two families also mix freely. Television is half Greek, tele, and half Latin, vision. Nobody stopped to check.

Why does the family matter to you? Because it tells you where to expect a stem. If you meet hydro in a chemistry text, you can guess it means water, since hydro is Greek and Greek stems fill science. If you meet a Latin stem like cred in a news story about banks, you can guess it has to do with believing or trusting. The family is a clue about the neighborhood the word lives in.

Start with bio, a Greek stem meaning life. Biology is the study of life. A biography is the written story of a person’s life. An autobiography is a life story you write yourself. Antibiotics are medicines that work against tiny living things that make you sick. A biome is a large region of living things, like a desert or a forest. Every time you see bio, look for life.

Next is geo, Greek for earth. Geology is the study of the earth, its rocks and its layers. Geography is writing or drawing about the earth, which is why maps belong to it. A geode is a rock with crystals inside. In math, geometry began as the measuring of earth, the tool ancient people used to lay out fields and mark borders after floods.

The third stem is graph, from a Greek word meaning write or draw. A photograph is drawn by light. An autograph is a name written by the person who owns it. A paragraph is a group of written lines. A graph in math is a drawing of numbers. Notice how graph appears in both geography and photograph. That is a word family: different words that share a stem and share part of their meaning.

Here is a word you may meet in an Illinois science class: biogeography. It looks like a mouthful. Take it apart. Bio, life. Geo, earth. Graph, writing. Biogeography is the study of where living things live on the earth, and why. If you can build the meaning, you can read the whole page.

The stem log comes from the Greek word logos, which meant word, reason or study. That is why so many school subjects end in ology: biology, geology, psychology, technology. The ending means the study of. A dialogue is words spoken between two people. A logo is a picture that stands in for a company’s name. A logical argument is one that follows reason step by step.

Chron, spelled chron, means time. A chronological list is in time order, first to last. A chronic illness is one that lasts a long time. A chronicle is a record of events in the order they happened. Synchronized swimmers move at the same time. If you see chron in a history book, think about time, because that is what the word is measuring.

Phon, spelled phon, means sound. A telephone carries sound far away. A microphone makes a small sound big. A symphony is sounds put together. Phonics, which you may remember from early grades, is the study of the sounds letters make. A homophone is a word that sounds the same as another word, like their and there.

Watch how the stems combine. Chronology is chron plus logy, the study of time order. Phonology is the study of sounds in language. Your history teacher and your science teacher may never mention Greek, but they hand you Greek words every week. Now you can hand the meanings back.

The Latin stem spec means look or see. You already know inspect, to look closely into something. A spectator looks at a game. Spectacles are glasses you look through. A spectacular sunset is one worth looking at. To respect someone is, in the oldest sense, to look back at them with care. When you suspect something, you look at it with doubt. The stem sometimes changes its spelling to spect or spic, as in conspicuous, easy to see.

The Latin stem port means carry. A porter carries luggage. To transport is to carry across. To import is to carry goods into a country, and to export is to carry them out. A portable speaker is one you can carry. Even a report carries information back to someone. The seaport where ships carry goods in and out shares the same stem.

Chicago has a lot of port words. It sits on Lake Michigan and grew rich because goods were carried in and out by water and rail. O’Hare is an airport. Trucks on the highways are part of transportation. The city itself was a port long before it had skyscrapers.

Try two hard words. Introspection: intro means inside, spec means look, tion makes it a thing. Introspection is looking inside yourself at your own thoughts. Deportation: de means away, port means carry, ation makes it a thing. Deportation is being carried away out of a country. Two words you might never have studied, and you can read both.

The stem rupt means break. A pipe ruptures when it breaks open. An interruption breaks into a conversation. A volcano erupts when it breaks out. A corrupt official is one whose honesty has been broken. A bankrupt business is one whose money has run out, from an old Italian custom of breaking a money changer’s bench when he failed. All of these words share the picture of something breaking.

The stem ject means throw. To reject a plan is to throw it back. To eject a disc is to throw it out. To inject medicine is to throw it in, with a needle. A projectile is something thrown forward. Even the word object, in its oldest sense, was a thing thrown in your way. When you see ject, picture an arm throwing.

The stem dict means say. A dictionary is a book of things said, or words. To dictate is to say words aloud for someone to write down. A verdict is a truth said by a jury at the end of a trial. A dictator is a ruler whose word is law. A prediction says what will happen before it does.

Notice how the same prefixes keep coming back. Inter, meaning between, gives you interrupt and interject. Pre, meaning before, gives you predict and prevent. E or ex, meaning out, gives you erupt, eject and exit. Once you know a dozen prefixes and a dozen stems, you can mix and match them into far more words than you memorized.

The Latin stem cred means believe. A credible story is one you can believe. An incredible story is one you cannot believe, though today people also use it to mean amazing. Your credit at a store is the trust that you will pay later. A creed is a statement of beliefs. When a witness is discredited, people stop believing her. The stem asks one question: can this be trusted?

The stem bene means good or well. A benefit is a good result. A benefactor is someone who does good for others, often by giving money. A benediction is a good saying, a blessing. If a doctor says a growth is benign, that is the good news: it is harmless. Bene is the stem you want to hear.

The stem mal means bad. Malnutrition is bad nourishment, not enough food. A malfunction is when a machine works badly. Malice is the wish to do harm. Malware is software written to do bad things to your computer. A malignant growth is the dangerous kind. Bene and mal are opposites, and doctors, lawyers and computer technicians use both every day.

Try a word from the news: malpractice. Mal means bad, practice means the work a professional does. Malpractice is when a doctor or lawyer does the job badly enough to cause harm. Now try benevolent. Bene means good, and vol comes from a Latin word for wishing. A benevolent person wishes others well. You just read two college-level words.

Some stems almost always sit at the front of a word, so people call them prefixes. The prefix anti means against. An antibiotic works against living germs. Antifreeze works against freezing. An antonym is a word against another word, its opposite. The Antarctic is the region opposite the Arctic. Do not confuse anti with ante, which means before, as in anteroom, the room before the main room.

The prefix auto means self. An automobile moves by itself, without a horse. An autograph is written by the person’s own self. An autobiography is a life story written by the self. Automatic doors open by themselves. In social studies, autonomy is self-rule, the right of a people to govern themselves.

The prefix tele means far or distant. A telephone carries sound far. A telescope lets you look far. A television carries pictures far. Telecommuting is working far from the office. When the word telegraph was invented in the 1800s, it meant exactly what its pieces said: writing sent far, over a wire.

These three prefixes love to join other stems from this chapter. Anti plus bio plus tic gives antibiotic. Auto plus graph gives autograph. Tele plus phon gives telephone. Tele plus scope, from a Greek word for looking, gives telescope. When you meet a new word starting with anti, auto or tele, cut the prefix off first and see what stem is left.

The Greek stem micro means small. A microscope lets you look at small things. A microphone makes small sounds loud. A microwave oven uses short waves. Microbes are tiny living things. In economics, microeconomics studies small units like one family or one store. Its opposite is macro, meaning large.

The stem poly means many. A polygon is a shape with many angles and sides. Polyester is a fabric made from many linked chemical units. A polyglot is a person who speaks many languages. Polytheism is belief in many gods, and monotheism, with mono meaning one, is belief in one. In math class you may meet polynomials, expressions with many terms.

The stem hydro means water. Hydrogen is the element that, when burned, makes water. A hydrant gives water to firefighters. Hydroelectric power comes from moving water, like the dams on the Mississippi River. A hydroplane skims across water. To hydrate your body is to give it water. Dehydration, with de meaning away, is losing water.

Look at a word from a biology textbook: microorganism. Micro, small. Organism, a living thing. A microorganism is a living thing too small to see. Now a word from chemistry: hydrophobic. Hydro, water. Phobic, fearing or avoiding. A hydrophobic surface pushes water away, like a waxed car hood. Each time, the parts told you the meaning before the teacher did.

Take the stem photo, from a Greek word meaning light. In art class, a photograph is a picture drawn by light. In biology, photosynthesis is how plants use light to put together, syn and thesis, their food. In physics, a photon is a particle of light. In technology, a photocopy is made by light bouncing off a page. One stem, four classes, one family of words.

Now take graph again. In English you write a paragraph. In math you plot a graph. In social studies you read about geography and demographics, which is writing about people, from demos, the Greek word for the people. Democracy, rule by the people, shares that stem. A student who learns demos in history can read demographics in a health class without stopping.

Families also cross into everyday life. The stem cycl means circle or wheel. A bicycle has two wheels. A cyclone is a circling storm. To recycle is to send something around again. An encyclopedia was named as a circle of learning. The water cycle in science goes around and around. Every new cycl word joins a family you already know.

Here is the payoff. Vocabulary in school is not thousands of separate words to memorize. It is a few hundred stems, prefixes and suffixes that recombine. Learn photo once and you get photograph, photosynthesis, photon, photocopy and telephoto. That is why this chapter teaches stems and not lists. A stem is a word you learn once and use in every class.

Marisol’s method works in every class, and it has four steps. First, find a stem you know. Second, cut off any prefix at the front and any suffix at the end, and say what each one adds. Third, build a rough meaning from the pieces. Fourth, and this is the step people skip, check that meaning against the sentence. If it fits, keep going. If it does not, the word may have drifted from its roots, and you need another clue.

Try it on a social studies word: chronological. Chron, time. Logical, having to do with order or reason. Rough meaning: in time order. Check: the sentence says to put the events of the Revolution in chronological order. The meaning fits. Now try a science word: geothermal. Geo, earth. Thermal, from a Greek word for heat. Rough meaning: earth heat. Check: the passage describes power plants that use heat from deep underground. It fits.

Sometimes the check fails, and that matters. The word manufacture has manu, hand, and fact, make. The rough meaning is made by hand. But a sentence about a factory that manufactures cars with robots does not fit that meaning. The word has changed over centuries to mean made in a factory, by hand or not. The stems gave you a start; the sentence corrected it. Do both.

You can practice this in the Word Foundry and the class stem units on this site, which are practice rooms for taking words apart and putting them together. Do a few each week. The goal is not to know Greek. The goal is to sit down for a test, meet a word you never studied, and feel curious instead of stuck.

Look at three words: thin, slender, scrawny. Open a dictionary and all three point at the same fact, a body without much fat on it. That shared dictionary meaning is the denotation. But nobody would be pleased to be called scrawny. Slender sounds graceful. Thin sounds neutral. Scrawny sounds weak and underfed. The feeling that comes with each word is its connotation.

Connotations can be positive, negative or neutral. A house is neutral. A home is warm. A shack is poor and falling apart. A mansion is rich. When a writer chooses one of these words, she is choosing a feeling for the reader, not just a building. Newspapers know this. A headline that says officials gathered feels calm. One that says officials huddled feels secretive.

Connotations come from how people have used a word over time. Cheap and inexpensive both mean low in price. But cheap has been used so often for badly made things that it now carries a sneer. Inexpensive stays polite. Stubborn and determined both mean unwilling to give up. One is a complaint, and the other is praise. Same behavior, different feelings.

Why does this matter to you? Because readers respond to connotation whether or not they notice it. If you write that a character stared, she seems intense. If you write that she gazed, she seems dreamy. If you write that she glared, she seems angry. You did not add a single adjective. You picked a verb with the right feeling on its back.

Read two sentences about the same event. The crowd trickled into the old gym and settled onto the worn bleachers. The crowd crammed into the dingy gym and slumped onto the rickety bleachers. Same gym, same crowd, same night. The first sentence sounds fond and calm. The second sounds annoyed and a little disgusted. The difference is the writer’s tone, the attitude that comes through the words.

Tone is not stated. It is built. Worn is gentle and even affectionate, the way a favorite jacket is worn. Dingy is dirty and depressing. Settled is peaceful. Slumped is tired and unhappy. Each word choice tips the sentence a little further toward one attitude. By the end, the reader knows exactly how the writer feels about that gym, though the writer never said so.

Writers control tone by choosing between words with the same denotation. A politician can be described as firm or as rigid. A meal can be simple or bland. A friend can be careful or timid. Readers, and especially test makers, will ask you to identify tone: admiring, mocking, sad, playful, angry, respectful. To answer, find the loaded words and ask what feeling they share.

Here is a quick test for your own writing. Underline the nouns, verbs and adjectives in a paragraph. Next to each, write plus, minus or zero for its connotation. If you wanted a warm paragraph and half your words are minus, you have found the problem. Tone is a total. Every word you pick either adds to it or fights it.

A thesaurus is a book or a tool that lists synonyms, words with similar meanings. Type in walk and it offers stroll, march, trudge, saunter, stomp, wander and pace. That is useful when you have written walked six times in one paragraph. It is dangerous when you grab a word without knowing what it carries. A soldier marches. A tired hiker trudges. Nobody saunters into a burning building.

The classic mistake is trading a plain word for a fancy one to sound smart. A student writes, The dog was happy, checks the thesaurus, and produces, The canine was jubilant. Jubilant means wildly joyful, celebrating a victory. A dog wagging its tail is not jubilant. The fancy word is wrong, and it makes the sentence sound like a costume. Precise beats impressive.

Use the thesaurus in three steps. First, know what you mean exactly: not just walked, but walked slowly and sadly. Second, look at the list and pick a candidate that fits that exact meaning: trudged. Third, read the whole sentence with the new word out loud. If it sounds like something a real person would say, keep it. If it sounds like a costume, go back to the list or keep the plain word.

One more check: look up your new word in a dictionary, not just the thesaurus. The thesaurus tells you that words are neighbors. The dictionary tells you exactly how they differ. Together they let you choose the word with the right denotation and the right connotation for the sentence you are writing.

Her voice was like gravel in a blender. You have never heard that voice, but you know it now: rough, loud, grinding. That sentence is a simile, a comparison between two unlike things using the word like or as. The voice is one thing. Gravel in a blender is another. Putting them side by side makes the voice instantly real.

Not every sentence with like is a simile. My brother is like my cousin compares two similar things, so it is just a plain comparison. A simile needs two things that do not belong together: a voice and gravel, a runner and a deer, a mind and a steel trap. The distance between them is where the surprise lives. The closer they are, the less the simile does.

A simile also needs a point. When you write as busy as a bee, ask what quality you are borrowing from the bee. Busyness. When Robert Burns wrote that his love was like a red, red rose that had newly sprung in June, he borrowed the rose’s freshness and beauty. The comparison tells you which quality to notice. That is called the ground of the comparison.

Worn-out similes have lost their surprise: as cold as ice, as quiet as a mouse, as strong as an ox. They are so familiar that readers skip them. When you write your own, hunt for a comparison that is true and that nobody has used. The cafeteria line moved like a checkout on a holiday. The new teacher’s handwriting looked like fallen fence posts. Fresh similes make readers see.

The classroom was a zoo. No like, no as. The sentence does not say the room was like a zoo; it says the room was a zoo. That is a metaphor, a comparison that states one thing is another. Because it drops the like, a metaphor is bolder than a simile. It asks the reader to hold two pictures in one place: a classroom and a zoo, a heart and a stone, a city and a jungle.

Metaphors can hide in verbs and adjectives too, not just in is sentences. Prices soared. A voice cut through the noise. She drowned in homework. Nobody flew, nothing was sliced, no one got wet. Each verb quietly compares one thing to another. Prices are treated like a bird, a voice like a knife, homework like water. Once you notice these hidden metaphors, you find them everywhere, even in science and math class.

Shakespeare’s Jaques begins a famous speech with a metaphor: All the world’s a stage, and all the men and women merely players. The world is not a stage. But once you accept the comparison, the rest follows. People enter, play their parts and exit. An extended metaphor like this one keeps building on the same comparison for a whole passage.

When you read a metaphor, ask two questions. What two things are being compared? And what quality moves from one to the other? In Time is money, time is compared to money, and the quality that moves is value: time can be spent, saved or wasted. Answer those two questions and you have interpreted the metaphor.

The wind moaned around the corner of the house. The old truck coughed, groaned and finally refused to start. Wind cannot moan and a truck cannot refuse. Those sentences use personification, giving human actions or feelings to something that is not a person. The technique is old and everywhere: the sun smiles, the flowers dance, the alarm clock screams, the city never sleeps.

Personification works because people understand people. If a writer says the fog came in on little cat feet, as Carl Sandburg did in his 1916 poem about Chicago fog, you feel how quietly it arrives and how it seems to sit and watch before it moves on. Sandburg gives the fog a cat’s body. Emily Dickinson goes further in a poem that begins, Because I could not stop for Death, He kindly stopped for me. Death becomes a polite driver with a carriage.

Personification is a kind of metaphor. It compares a thing to a person and carries over one human quality: patience, anger, kindness, stubbornness. A good one picks the quality carefully. The refrigerator hummed a lazy tune tells you the kitchen is calm. The refrigerator growled tells you something is wrong with it, or with the mood in the room.

When you write, use personification to give a mood to a place or a thing. Do not pile it up. One moaning wind sets a scene. Five moaning, sobbing, shrieking, whispering, sighing winds in one paragraph turn a scene into a joke. Choose one human action, make it exact, and move on.

I have told you a million times. My backpack weighs a ton. I could eat a horse. Nobody has said anything a million times, backpacks weigh a few pounds and no one eats a horse. These are hyperbole, exaggeration on purpose. The speaker does not expect to be believed. The exaggeration measures a feeling: frustration, weariness, hunger. The bigger the stretch, the bigger the feeling.

Hyperbole is a favorite of tall tales. American folklore has Paul Bunyan, a lumberjack so huge his footprints filled with water and became lakes, and Pecos Bill, who rode a tornado. Nobody believes it, and that is the fun. Comedians use hyperbole constantly. So do sports announcers: the fastest player who ever lived, a catch nobody else on Earth could make.

The danger with hyperbole is that it can hide behind a fact. An ad that says everybody is switching to this phone is hyperbole dressed as news. A friend who says you never listen is exaggerating in the middle of a real argument. When you read, ask whether a big claim is measured or stretched. When you write an argument essay, avoid it; readers who catch one stretch stop trusting your numbers.

In stories and poems, though, hyperbole is a tool. It shows how a character feels from the inside. A boy who says the walk to the principal’s office took a hundred years is telling you about dread, not distance. The exaggeration is the truth about the feeling, delivered by a lie about the fact.

A coach says the new quarterback is the team’s Achilles’ heel. A reporter calls a proposal a Trojan horse. A teacher warns that a plan will open Pandora’s box. None of these people are talking about ancient Greece. They are using an allusion, a quick reference to a story the listener is expected to know, so that the whole story’s meaning arrives in two or three words.

Each of those allusions carries a story. Achilles was a Greek hero who could not be wounded anywhere except his heel, so an Achilles’ heel is a single weak spot. The Trojan horse was a gift that hid enemy soldiers, so a Trojan horse is something harmful disguised as something good. Pandora opened a box and released troubles into the world, so opening Pandora’s box means starting problems you cannot stop.

Allusions come from everywhere people share stories: myths, the Bible, history, fairy tales, famous books, movies and songs. Calling someone a Scrooge alludes to Dickens. Saying a place is no Garden of Eden alludes to the Bible. Calling a bad decision a Titanic alludes to the 1912 shipwreck. If you do not know the story, the allusion goes past you. That is a reason to read widely.

When you meet a name or phrase that seems to come from nowhere, treat it as a possible allusion. Ask: is this a story I half know? Look it up. Then ask what quality the writer is borrowing. An allusion works exactly like a metaphor, except that the second half of the comparison is a story you have to supply yourself.

It is raining cats and dogs. He let the cat out of the bag. She hit the books. Each one is an idiom, a phrase whose meaning is not the sum of their words. No animals fall from the sky. Hitting a book does not help you study. An idiom has to be learned whole, the way you learn a single word. Every language has thousands, and they are one of the hardest parts of learning a new language.

Idioms are a special problem for readers who are learning English, and an unfair one, because the words are all easy. Break a leg means good luck. Piece of cake means easy. Under the weather means sick. Cost an arm and a leg means expensive. If you take these literally, the sentence turns strange. If you know them, they are as clear as any word. When a sentence with simple words makes no sense, suspect an idiom and look it up.

Idioms differ from metaphors in one way. A fresh metaphor is invented by a writer and asks you to picture two things. An idiom was a metaphor once, maybe centuries ago, but the picture has faded. When someone says she spilled the beans, nobody sees beans. The phrase now just means told the secret. Idioms are metaphors that have gone to sleep.

In your own writing, idioms make dialogue sound natural, because real people use them all the time. In formal writing, they can sound sloppy, and a reader from another country may not understand them. A science report should say the results were unexpected, not the results came out of left field. Know which room you are writing in.

A teacher explaining the heart says it is like a pump in a house’s plumbing: a muscle that pushes fluid through pipes to every room. That is an analogy, a comparison that explains how something unfamiliar works by matching it to something you already understand. Analogies are longer and more practical than similes. Their job is not surprise but understanding.

On tests, analogies often appear in a compressed form: puppy is to dog as kitten is to cat. The two pairs share a relationship. A puppy is a young dog; a kitten is a young cat. To solve one, find the relationship in the first pair and state it in a sentence. Then check that the same sentence works for the second pair. Hot is to cold as up is to down: both pairs are opposites.

Common relationships include part to whole, such as petal is to flower; worker to tool, such as carpenter is to hammer; cause to effect, such as rain is to flood; word to synonym or antonym; and category to member, such as fruit is to apple. Write the relationship as a sentence and the puzzle usually opens. If two answer choices both seem to fit, make your sentence more exact.

Analogies also drive good explanations in science and history. An atom is like a tiny solar system. A cell membrane is like a security guard at a door. The colonies under Britain were like teenagers with a strict parent. Each analogy is imperfect, and part of thinking well is knowing where it breaks down. Electrons do not orbit like planets. But as a first step, a good analogy carries a reader most of the way.

A poem uses figures of speech to make a reader feel something exact in a small space. Emily Dickinson begins a poem, Hope is the thing with feathers, that perches in the soul. Hope has no feathers. But once hope is a bird, the poem can say it sings without words and never stops. To interpret the figure, ask: what is compared to what, and why that thing? A bird is small, alive, light and hard to catch. So is hope.

Ads use the same tools for a different reason: to make you want something. A car ad says the new model is a beast. A phone is your window to the world. A cereal gives you a mountain of energy. Beast is a metaphor for power. Window is a metaphor for access. Mountain is hyperbole. The ad borrows a feeling from the image and pins it on the product. The poem wants you to see. The ad wants you to buy.

Both depend on context. The word beast in a car ad means powerful. The word beast in a story about a barn means a farm animal. The same word in a sentence about a rude person means cruel. You cannot interpret a figure by itself; you read the sentences around it and ask which meaning fits. Test questions on figurative language almost always give you a passage for this reason.

Here is a habit for both poems and ads. When a sentence cannot be literally true, stop. Name the figure: simile, metaphor, personification, hyperbole, allusion or idiom. Say what two things are compared. Say what quality moves across. Then ask what the writer wants from you. A poet wants you to see and feel. An advertiser wants your money. Knowing the difference is part of reading.

Read this sentence: The weather was bad and the game was really fun anyway. Now read this one: Sleet needled our faces, and we played the whole second half laughing. The first is vague. Bad and fun and really tell the reader almost nothing. The second is precise. Sleet is exact. Needled is a metaphor that makes the sting real. Laughing shows the fun instead of announcing it.

Precision starts with nouns and verbs. Do not write a bird flew when you mean a hawk circled. Do not write she went when you mean she stomped, drifted or sprinted. Replace very tired with exhausted, very big with enormous, very small with tiny. A specific noun or verb usually does more than a plain one plus an adverb. Then check your connotations. Does each word carry the feeling you want?

Add figures of speech the way a cook adds salt: where they sharpen the taste, and not everywhere. One fresh simile in a paragraph makes a reader see. Three make the reader tired. Cut clichés, the worn-out figures like as cold as ice and busy as a bee. Cut hyperbole from anything that needs to be believed. Keep an idiom in dialogue if a real person would say it, and cut it from a formal report.

Revise with a list of questions. Is each noun the most specific one? Is each verb doing real work? Does every connotation match my tone? Is every figure fresh, and does it carry the right quality? Would a reader who does not know me understand every idiom? If the answer is yes all the way down, your sentence is doing what you meant it to do. That is what precise language means.
