Word Knowledge (WK) AFQT

Word Knowledge (WK) measures your vocabulary — how well you understand what words mean, both on their own and in a sentence. It is one of the four AFQT subtests that determine your enlistment eligibility.

  1. Vigilant most nearly means

    1. exhausted
    2. watchful
    3. cheerful
    4. stubborn

    Vigilant means keeping careful watch for possible danger or difficulties, so 'watchful' is the closest synonym. The other choices describe unrelated states.

  2. The mechanic gave a candid assessment of the car's problems. Candid most nearly means

    1. hesitant
    2. honest
    3. lengthy
    4. confusing

    Candid means truthful and straightforward, so 'honest' fits best. A candid assessment holds nothing back, unlike a hesitant or confusing one.

  3. Abundant most nearly means

    1. plentiful
    2. costly
    3. hidden
    4. fragile

    Abundant means existing in large quantities, which matches 'plentiful.' The other options describe price, concealment, or delicacy rather than quantity.

  4. After the long drought, the farmers felt a growing sense of dread. Dread most nearly means

    1. curiosity
    2. fear
    3. relief
    4. boredom

    Dread is a strong feeling of anxiety or fear about something that may happen, so 'fear' is correct. Relief and boredom are nearly opposite in tone.

  5. To conceal something most nearly means to

    1. hide it
    2. break it
    3. clean it
    4. measure it

    Conceal means to keep something out of sight or secret, which is the same as 'hide it.' The other verbs describe unrelated actions.

  6. Diligent most nearly means

    1. careless
    2. hardworking
    3. wealthy
    4. talkative

    Diligent describes someone who works steadily and with careful effort, matching 'hardworking.' It is the opposite of careless.

What it measures

Word Knowledge tests your vocabulary: how well you recognize the meaning of a word and choose the answer that most nearly matches it. It is a fast, straightforward subtest, but it carries real weight because it is one of the four AFQT subtests — Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Word Knowledge (WK), and Paragraph Comprehension (PC).

Your AFQT score is the percentile that decides whether you can enlist and helps set which jobs you qualify for. WK feeds it twice: it combines with PC to form your Verbal Expression (VE) score, and VE is counted at double weight in the AFQT formula. In other words, gains on Word Knowledge move your enlistment score more than gains on most other subtests, so it is one of the highest-leverage areas to study.

What's on it

Skills and question types you'll see

  • Synonyms: a single word is given, and you pick the answer that "most nearly means" the same thing.
  • Words in context: the word appears in a short sentence, and you choose its meaning as it is used there.
  • Everyday and academic vocabulary drawn from general reading, not military jargon.
  • Prefixes, suffixes, and root words that let you decode unfamiliar terms (for example, pre-, -able, bene-).
  • Shades of meaning: telling close-but-wrong answer choices from the best match.

How to study it

The best long-term strategy is simple: read widely and look up every word you don't know. News articles, nonfiction, and even quality fiction expose you to the kind of general vocabulary WK draws from. Keep a running list of unfamiliar words with short, plain-language definitions and review it often. Spaced repetition — reviewing a word today, in a few days, then a week later — locks words into memory far better than cramming.

Learn word parts. Most English words are built from roots, prefixes, and suffixes, so a handful of them unlocks hundreds of words. If you know bene- means "good," you can reason that benevolent and beneficial are positive. This is your best tool for words you have never seen.

On test day, use smart guessing. If a word stumps you, break it into parts, and use the sentence's tone (positive or negative) for context questions. Then eliminate the choices you know are wrong before guessing — there is no penalty for a wrong answer, so never leave a question blank. WK is timed and has many items, so keep a steady pace and don't stall on any single word.

Common mistakes to avoid: don't pick a word just because it looks or sounds like the question word (test writers include those look-alikes as traps). Don't overthink — WK wants the most nearly correct meaning, not a perfect one. And don't rely only on memorizing giant word lists; understanding word parts and reading in context sticks better and prepares you for words no list covered.
