Antonyms & Opposites

How the test phrases an opposite question

Most Word Knowledge questions ask for a synonym ("most nearly means"). A smaller set asks for the opposite. The wording is the only signal, and it is easy to miss when you are moving fast:

• "WORD is most nearly OPPOSITE in meaning to:"
• "Which word is most nearly the opposite of WORD?"
• "WORD most nearly means the opposite of:"

The dangerous part is that opposite questions usually draw from the same kind of answer pool a synonym question would. One choice is a clean synonym of the stem word. That synonym is the trap. Your job is to flip it.

The single best habit: before you read the choices, say the stem word's meaning in your own head, then say its opposite. Hunt for that opposite. If you skip this step and read the choices first, the synonym jumps out and feels right.

Part of speech has to match

The correct opposite is always the same part of speech as the stem word. If the prompt word is an adjective, the answer is an adjective. If it is a verb, the answer is a verb.

• ABSENT (adjective) opposite is PRESENT (adjective), not ATTEND (verb)
• ACCELERATE (verb) opposite is DECELERATE or SLOW (verb), not SLOWNESS (noun)
• VICTORY (noun) opposite is DEFEAT (noun), not LOSE (verb)

Test writers sometimes plant a right-meaning word in the wrong part of speech to catch you. Checking the form first eliminates it quickly.

Match the degree, not just the direction

Opposite is about direction and strength. Two words can point the right way but miss the intensity.

• ENORMOUS means very large. Its true opposite is TINY, not just SMALL.
• ADORE means to love deeply. Its true opposite is DETEST or LOATHE, not merely DISLIKE.
• FRIGID means extremely cold. Its true opposite is SCORCHING or SWELTERING, more than just WARM.

When two choices both move in the opposite direction, pick the one whose intensity mirrors the stem word.

Near-opposite vs. unrelated distractors

Wrong answers on an opposite question come in three flavors. Knowing the pattern speeds up elimination:

1. The synonym trap. Closest in meaning to the stem word, and therefore the exact wrong answer. Spot it and rule it out first.
2. The near-opposite or "merely different" word. Points away from the stem word but is not its true opposite. The opposite of CONSTRUCT is DEMOLISH, not REPAIR; repair is different from constructing, but it is not the opposite.
3. The unrelated word. No real connection at all. Easiest to drop.

Eliminate the unrelated words, then decide between the true opposite and the near-opposite. The true opposite is the one you could swap into "the opposite of X is ___" and have it sound exactly right.

Use prefixes to find the opposite

Several prefixes exist specifically to reverse a word's meaning. If you spot the base word inside an answer choice with one of these prefixes attached, that choice is often the opposite:

• a- (without, not): typical / atypical, symmetrical / asymmetrical
• un- (not, reverse of): biased / unbiased, lock / unlock, able / unable
• dis- (apart, opposite of): agree / disagree, approve / disapprove, honest / dishonest
• in-, im-, il-, ir- (not): visible / invisible, possible / impossible, legal / illegal, regular / irregular
• non- (not): sense / nonsense, conformist / nonconformist
• anti- (against, opposite): clockwise / anticlockwise, social / antisocial

Two cautions. First, not every word starting with these letters uses the prefix that way: "invaluable" means extremely valuable, not "not valuable," and "inflammable" means easy to burn. Second, the prefix tells you the relationship, but you still confirm by meaning. Use the prefix as a fast clue, then check that the choice truly reverses the stem word.

Strategy for opposite questions

1. Read the stem carefully and confirm it is asking for the opposite, not the synonym
2. Define the stem word in your own words, then state its opposite before looking at choices
3. Note the part of speech, the answer must match it
4. Spot and discard the synonym trap
5. Drop unrelated words
6. Choose between the true opposite and the near-opposite by checking direction and degree
