What WK measures

Vocabulary breadth and the ability to determine word meaning from context. Feeds into the Verbal Expression (VE) composite.

What appears on the test

  • Direct Synonym"X most nearly means ___"
  • Context Clue"In this sentence, X means ___"
  • Antonym EliminationEliminate opposites to find the synonym
  • Root/Prefix/SuffixUse word parts to determine meaning
Worked example

Use the sentence to confirm meaning

The policy was ambiguous, or unclear, to most readers.

ambiguousor unclear
ambiguous = unclear
A nearby restatement can define an unfamiliar word directly. Substitute the meaning back into the sentence before choosing an answer.

What to study for WK

Word Knowledge rewards vocabulary, but it also rewards method. Break unfamiliar words into roots and affixes, test each choice in context, and eliminate choices whose tone or degree does not match.

01

Roots, prefixes, and suffixes

Use meaningful word parts to estimate an unfamiliar word before looking at the choices.

View key facts
  • Prefixes often change direction, degree, number, or negation.
  • Roots carry the core meaning; suffixes often indicate part of speech.
  • A word can contain more than one useful clue, such as a prefix plus a Latin root.
02

Direct synonyms

Choose the option closest in meaning and degree, not merely a word from the same broad category.

View key facts
  • Replace the tested word with each choice and listen for the closest meaning.
  • Watch intensity: “annoyed” is not as strong as “furious.”
  • Eliminate antonyms and unrelated choices before deciding between close options.
03

Meaning from context

Use contrast, examples, definitions, and cause-effect clues in the sentence.

View key facts
  • Words such as “but,” “although,” and “unlike” signal contrast.
  • A comma or dash may introduce a definition or example.
  • The surrounding sentence can reveal whether the word is positive, negative, or neutral.
04

Connotation and precision

Match emotional tone and exact usage when two choices have similar dictionary meanings.

View key facts
  • Connotation is the feeling associated with a word beyond its literal definition.
  • Choose the same part of speech as the tested word when possible.
  • A precise synonym should work in the sentence without changing its meaning.
05

Vocabulary retention

Learn words through retrieval and repeated encounters rather than one-time rereading.

View key facts
  • Write your own sentence and a simple synonym for each new word.
  • Review missed words on expanding intervals.
  • Group related roots and word families to multiply what one flashcard teaches.

  3. Use the sentence tone to eliminate choices with the wrong connotation.
  4. Keep a missed-word deck and review by active recall.
  5. Practice at the CAT pace: roughly 36 seconds per scored question.
