Everything the adaptive question bank can teach and test in Usage & Diction, from foundations through advanced practice. Work through it in order, or start practicing and let the questions find your level.
Read the whole sentence and say the missing idea in your own words, such as "a place" or "to draw out". Only then look at the choices. Reading the options first lets a familiar spelling pull you toward it, while a meaning you have already named sorts the options for you.
Many questions add a short gloss such as "(a wooden beam)" or "(tone of a voice)". That gloss settles which word of a sound-alike set is wanted: timber for the beam, timbre for the tone. Find the word that carries the meaning, then check that the option spells it exactly.
Most sets mix one or two real words with invented spellings. Crossing out the non-words leaves a real choice of two or three. The trap runs both ways: a correctly spelled wrong word is still wrong, and the right word may appear twice, once spelled correctly and once with a letter off.
Ask whether the gap wants a noun, a verb, an adjective or an adverb. "She will ___ the plan" needs a verb; "a ___ plan" needs an adjective. Many confusable pairs split exactly along that line, so naming the slot often removes half the options before meaning comes into it.
Put a plain gloss in place of each candidate and read the sentence aloud. For "The picnic called for ___ shoes", try "(informal) shoes" and "(having to do with cause) shoes": only the first makes sense, so the word is casual, not causal. If no gloss fits, recheck the slot you named.
B. Words that sound alike
Homophones such as breach and breech, or maize and maze, cannot be told apart by ear, so the spelling is the whole signal. A breach is a gap; a breech is a lower part. Maize is corn, and a maze is a puzzle of paths. Learn each spelling together with its meaning.
Pick the letter the two spellings do not share and hang the meaning on it. A carat weighs a gem, and caret, with its "e", is the editor’s mark for something left out. Making up the hook forces you to look at the one letter that differs, which is exactly where the two words get swapped.
Sets like rows, rose and roes hide three jobs: lines or oars at work, a flower or a past tense, and fish eggs. Test each against the slot: "The heron ___ from the marsh" needs a past-tense verb, so rose. Eliminating by meaning is faster than staring at three similar spellings.
Some sound-alikes pair a past-tense verb with a noun or adjective: tacked and tact, chased and chaste. In "She ___ the notice to the board" the slot needs an action in the past, so tacked. If the slot needs a thing or a quality instead, the shorter spelling is the one.
Interment and internment differ by a single "n". Interment is burial; internment is confinement, as in a camp or a jail. Pairs like these are misheard rather than misspelled, so pronounce each option carefully and match the sound you hear to the meaning.
Cloth is the fabric and clothe is what you do with it, as in "to clothe a thought in plain words". The same split runs through several "th" pairs. When a slot needs an action after "to" or a helping verb, reach for the form with the final "e"; when it needs a thing, take the shorter one.
A prophecy is the thing foretold; to prophesy is the act. A device is a contrivance, while devise is a verb. Name the slot first, then pick the matching letter. US usage has exceptions: practice serves as both noun and verb, so the rule is a guide, not a law.
Choosing the right word is half the job when the other options include a near-miss spelling of it. Accommodate has two "c"s and two "m"s, and a version with one of either is wrong. Check doubled letters, silent letters and endings like "-ance" against "-ence" before you commit.
C. Words that look alike
Spacious has to do with space; specious means plausible on the surface. The two differ by a single vowel. A lath is a thin strip of wood, and a lathe is a machine that shapes wood as it spins. Eyes skim familiar shapes, so slow down on pairs that look alike and say each one aloud.
An emigrant leaves a country; an immigrant arrives in one. The same traveler is both, depending on which country you stand in. A family leaving Portugal for Brazil emigrates from Portugal and immigrates to Brazil. Ask which side of the border the sentence is standing on.
Traditional usage splits this pair. Healthful describes what promotes health, such as a climate or a meal; healthy describes the condition of a living thing, such as a child or a plant. "A healthful soup kept the patient healthy" keeps the distinction. Ask whether the word names a cause or a condition.
A doorbell that rings every few minutes makes a continual noise; the hum of a refrigerator that never stops is continuous. Picture the timeline: separate marks with gaps between them, or one unbroken line. Both words mean "going on", so the gap is the whole difference.
To teach is to give knowledge and to learn is to receive it. Bring moves something toward the speaker and take moves it away, while carry says only that it is borne, in no set direction. "The guide ___ us the trail names" wants the giver, so taught. Draw an arrow from the person acting to the one receiving.
Some words look like a familiar word and mean something else. A perquisite is a privilege that comes with a job; a prerequisite is a requirement you must meet first. A quick glance matches the shape you know best. When two options share most of their letters, confirm each meaning first.
D. Pairs that grammar decides
It’s means it is or it has, who’s means who is or who has, and you’re means you are. Read the sentence with the long form: "The orchard lost it is oldest tree" is nonsense, so the word wanted is its. The test is mechanical and settles a contraction pair in a few seconds.
Nouns show ownership with an apostrophe, as in "the lighthouse’s lamp", which is why "it’s" looks right to many writers. Personal pronouns have their own possessive forms: its, hers, ours, yours, theirs, whose. It’s and who’s are contractions, and her’s or our’s are simply errors. Indefinite pronouns differ: one’s and another’s do take the apostrophe.
Ask whether something is being placed or lifted. You lay a towel on the sand, but you lie on it. You set a vase down, but the cat sits. You raise a flag, but the moon rises. If you can answer "lay what?" or "raise what?", choose the transitive verb.
The two verbs run lie, lay, lain and lay, laid, laid. So "Yesterday the dog lay by the stove" is correct, and "the dog laid by the stove" is not, because laying needs an object. The overlap in "lay" causes the confusion; work out the verb first, then its tense.
Fewer lanterns, fewer volunteers; less oil, less patience. If you can put a number in front of the noun, as in "three lanterns", the count words apply. A sum treated as one amount, such as ten dollars or two miles, is measured in bulk, so it takes less: "less than ten dollars".
A secret shared between two cousins stays between them; profits split among five partners are shared among them. That is the traditional rule. Between still serves more than two when each party is named and set against the others, as in a race between three runners. Count the parties, then ask whether they act as one group.
"The cabin is farther up the ridge" is a distance you could walk. "We need to look further into the costs" is a degree, with no road involved. Ask whether a map could show the gap; if it could, choose farther.
"The coach praised Rosa and I" sounds formal, but cover "Rosa and": "the coach praised I" is plainly wrong, so the answer is me. A pronoun after a preposition or a verb takes the object form, as in "a gift for Rosa and me". The test works for he and him, she and her, they and them.
Turn the clause into a statement: "___ did you invite?" becomes "you invited him", so whom. "___ invited you?" becomes "he invited you", so who. Whom is the object form, and it follows a preposition too: "to whom", "for whom".
In careful writing, like comes before a noun or pronoun and as before a clause with its own verb. "She sings like a lark" compares two things; "she sings as her mother did" compares actions, so as is the word. Like used to open a clause, as in "do like I do", has been faulted for well over a century and stays out of formal writing.
Than belongs after a comparing word: "taller than the fence", "rather walk than drive". Prefer carries its own comparison and takes to: "She prefers hiking to cycling", not "prefers hiking than cycling". When a sentence already has a comparing verb, look for to rather than than.
E. One word or two
Test with a split: if you can say "all of us are ready" or move "all" away from "ready", you want the two words. "The volunteers were all ready by six" means each was prepared. "The volunteers had already left" points to time, and "all" cannot be pulled out of it.
"The bridge was closed altogether" means entirely. "The geese flew south all together" means in one group. Try replacing the word with "completely": if the sentence still works, write it as one word; if "as a group" fits instead, write two.
Because awhile already contains the idea of "for", it does not follow a preposition. "The rain eased awhile" works, and so does "it eased for a while", but "for awhile" says "for" twice. After for, in, after or once, write the two words.
"Anyone can enter the race" means any person. "Any one of the four keys opens the shed" picks a single key. If you can add "of them" after the word, you want the two-word form. The same test separates everyone from every one.
"She walks the dog every day" can become "each day", so two words. "Rain boots are everyday wear here" means ordinary wear, and the word sits before a noun. The same pattern separates an adjective before a noun from an adverb phrase after a verb.
"The heron waded into the reeds" is movement. "The heron stood in the reeds" is position. "He handed his badge in to the clerk" keeps in with handed, so the words stay apart. Ask whether in belongs to the verb before you join it to "to".
Careful usage writes all right as two words, and US federal style lists only that form. A one-word spelling turns up in casual writing, but questions about standard usage expect the two words. If a sentence is formal and the options include both forms, choose all right.
F. The precise word
Words for spending carefully are a good example. Economy is wise management, frugality is sparing to a noticeable degree, and parsimony is saving for its own sake. All can describe the same household, yet each says something different. Ask what the sentence adds beyond the shared idea.
Economy and thrift describe good management, while miserliness and parsimony criticize. If the sentence says the habit "let the family buy a farm", it approves; if it says the habit "left the cupboard bare for guests", it disapproves. Match the word's charge to the sentence's tone.
Provoke and exasperate differ in force: to provoke is to call anger up, and to exasperate is to heighten anger already roused. One late bus might provoke a commuter; a third might exasperate her. Look for words in the sentence that signal how strong the feeling or quality is, then pick the matching step.
In "a ___ guide, who never wasted a word", the clause after the comma is a definition. Choose the option meaning sparing with words. Watch for the antonym planted among the options: it matches the topic, talking, but the opposite end of it.
Must says the reader has to act, must not forbids, may allows a choice and should advises. Shall is ambiguous: it can signal an obligation or only a prediction. Formal usage also asks permission with may and keeps can for ability: "May I leave early?" asks leave, while "Can I lift this?" asks whether you are able.
G. Idioms and set phrases
Idioms are learned as whole units, and their wording often preserves an older image or word. A learner who hears one aloud may write a sound-alike that seems to make sense. Picture the original image behind the phrase; if your version paints a different picture, check it.
Many nouns go with one verb by habit: you commit a crime and run a risk, and swapping the verb sounds wrong even when the meaning is clear. Weak verbs such as make, take, give and have often pair with a noun that hides the real action: "conduct an analysis" is just "analyze". Learn common pairings as units.
In careful usage one thing is different from another, following the verb differ from, and averse takes to. Two people differ with each other over an opinion but differ from each other in height. When a question tests a preposition, recall the word it follows, not the noun after it, and learn the two as a pair.
In speech "could have" shrinks to "could've", which sounds like "could of". The verb phrase needs have: "We should have taken the ferry". Expand any contraction you hear back to its full form before you write it, and "of" disappears.
Some phrases say the opposite of their intent when taken literally. "To enjoy poor health" has been criticized because nobody enjoys being ill. If a phrase is meant to show that someone cares nothing at all, the literal words should leave no room for caring.
Redundancy uses more words than the thought needs: "returned back again", "equally as well", "final completion". An abbreviation can hide one, since the "D" in "LCD" already stands for display. Spell the short form out; if a word appears twice, drop the copy.
H. Senses that shifted
Many words have a loose everyday use and a strict one that careful usage still keeps. Transpire strictly means to become known, as a secret leaks out; careful writers have long objected to it as a plain synonym for happen. Read the cue word: it asks which sense careful writers defend, not which one is commonest.
In careful usage a thing either has a parallel or it does not, so "very unique" is faulty: very implies degree. The same logic applies to perfect and complete, though good writers have long used "more perfect" anyway. When an option adds a degree to an absolute word, treat it as suspect.
The word comes from a Latin verb meaning to make heavy. A fever or a debt can be aggravated; a person is irritated or exasperated. "Damp weather aggravated his sore knee" is strict usage, while "the noise aggravated him" uses the looser sense.
Hang has two past forms with separate jobs. Hanged belongs only to the gallows; hung covers everything else: "The banners were hung from the balcony" and "the lamp hung low". Check what is hanging before you choose the form.
Ironic speech praises when it means to criticize, as in calling a downpour "lovely weather". Mere misfortune has no such reversal, so it does not fit. In an ironic situation, look for the same turn: a result that reverses what the setup led everyone to count on.
I. Plurals and spelling conventions
The common patterns are "-us" to "-i" (locus, loci), "-is" to "-es" (axis, axes), "-um" to "-a" (stratum, strata) and "-on" to "-a". Learn the pattern, then check the singular: a question about one thing needs the singular ending, not the familiar plural.
Antenna takes antennas in general use and antennae in zoology; index takes indexes, with indices in scientific work. Because both forms are standard, an option claiming that one of them is the only correct plural is suspect. When a question names a field, give that field’s form.
Because these plurals are far commoner than datum, criterion and phenomenon, writers slip into "a strange phenomena" or "this criteria". If the sentence is about one item, use the singular form. Data is sometimes treated as a collective singular, but criteria and phenomena are not.
US federal style writes practice and license. British writers have traditionally kept "licence" for the noun and "practise" for the verb, so a British-usage question may expect the noun and verb spelled differently. When a question names British usage, switch convention; otherwise answer in US spelling.
