Verbal Reasoning · Synonyms
The Verbal Reasoning section contains 40 questions in 20 minutes, about 30 seconds per question, the fastest pace on the ISEE. It measures vocabulary knowledge and the ability to reason with words through two question types: synonyms and sentence completion. Synonym questions usually come first, followed by sentence completions with one or two blanks.
Each synonym question presents a single word in capital letters followed by four answer choices. The task is to select the word whose meaning is most nearly the same as the capitalized word.

Understanding Word Relationships
Synonyms share a core meaning, but perfect synonyms are rare in English. Most pairs differ in intensity, formality, or connotation. "Happy" and "elated" both describe a positive emotional state, but "elated" suggests a stronger degree of happiness. When no choice matches exactly, choose the one closest to the word's primary meaning.
Focus on the primary definition. Many English words have several meanings, but synonym questions usually test the common definition rather than an obscure secondary sense. If none of the choices fits the common meaning, consider a second meaning of the word (for example, novel as an adjective means "new and original," not "a book").
Synonym Question Strategies
Define before looking
Form your own definition of the capitalized word before reading the choices. If you know the word means "to make smaller," look for that idea among the choices.
Use context from memory
Recall a sentence where you have seen the word. "The judge admonished the defendant" suggests that admonish relates to warning or scolding.
Eliminate clearly wrong answers
Cross out choices unrelated to the target word. With no penalty for wrong answers, eliminating even one choice improves the odds of a guess.
Watch for traps
Some wrong choices look or sound like the target word. Ingenious (clever) and ingenuous (naive) look alike but are nearly opposite; an antonym among the choices is often a trap.
Match the connotation
Words carry positive, negative, or neutral charges. Thrifty and stingy both describe careful spending, but thrifty is positive and stingy is negative.

Word Parts: Roots, Prefixes, and Suffixes
Strong vocabulary grows through steady practice over weeks, not last-minute memorization. Latin and Greek word parts form the foundation of thousands of English words, so learning them lets you decode an unfamiliar word by recognizing its components.

| aud | hear | audible audience auditorium , , |
| bene | good well , | benefit benevolent beneficial , , |

Prefixes
Prefixes attach to the beginning of a word and change its meaning. Recognizing a prefix often reveals a word's meaning even when the base word is unfamiliar.
| Type | Prefi xesandMeanings | Examples |
|---|---|---|
| Negative | un-; in-, im-, il -, ir-; dis-; non-; anti - (against); | unable impossible illegal irregular disconnect , , , , , |
| mis- (wrongly) | nonexistent antisocial mislead , , | |
| Quantity | mono-, uni - (one); bi -, du- (two); tri - (three); | monotone uniform bicycle duplicate trilogy quadrant , , , , , , |
| quad (four); multi poly- (many); semi - -, -, | polygon hemisphere , | |
| hemi (half) - | ||
| Directionandposition | pre- (before); post- (after); sub - (under); | preview postscript subterranean superior interact , , , , , |
| super- (above); inter- (between); trans- | transform | |
| (across) |
Suffixes
Suffixes attach to the end of a word and usually signal its part of speech, which helps on sentence completions where the blank must be a noun, verb, adjective, or adverb.
| PartofSpeech | Suffi xes | Examples | ||
|---|---|---|---|---|
| Noun | -tion , -sion , -ment , -ness , -ity , -ty , -er , -or , - | decision achievement darkness certainty actor , , , , , | ||
| ist -ance -ence , , | scientist confidence , | |||
| Adjective | -ful -less -ous -ious -able -ible -ive -al , , , , , , , | grateful endless curious visible creative musical , , , , , | ||
| Verb | -ize -ify -ate -en , , , | organize clarify evaluate strengthen , , , | ||
| Adverb | -ly -ward -wise , , | carefully backward clockwise , , | 1 |
Break an unfamiliar word into parts: in- (not) + cred (believe) + -ulous (inclined to) gives incredulous, "not inclined to believe," or skeptical. Word parts narrow the choices even when the full definition is uncertain.
