Start practice test →1. ABATE most nearly means:
- A.encourage
- B.subside✓ Answer
- C.purchase
- D.confess
Abate is a verb meaning to lessen in intensity or amount, as when a storm or a fever abates; 'subside' is the closest verb synonym because it also names a decrease in force over time. 'Encourage' moves in the opposite direction, and 'purchase' and 'confess' are unrelated actions. Note that all four options are verbs, matching the target's part of speech — on the ASVAB the key must always match the part of speech of the tested word.

2. CANDID most nearly means:
- A.cautious
- B.sweet
- C.frank✓ Answer
- D.wealthy
Candid is an adjective describing speech or a person that is open and straightforward, saying what is truly thought; 'frank' carries exactly that sense of unguarded honesty. 'Cautious' describes guarded speech, which is nearly the reverse of candid, and 'sweet' and 'wealthy' describe unrelated qualities. Recognizing that the key must be an adjective eliminates any noun option immediately.

3. The mechanic gave a CONCISE explanation of the repair. CONCISE most nearly means:
- A.loud
- B.confusing
- C.costly
- D.brief✓ Answer
Concise means expressing much in few words, so 'brief' is the closest match; the word describes length and economy of expression, not clarity, cost, or volume. 'Confusing' is a tempting tone-flipped distractor because a short explanation can be unclear, but conciseness says nothing about being hard to follow. The Latin root cis/cid ('to cut') is the decoding clue: a concise explanation has been cut down.

4. DETER most nearly means:
- A.discourage✓ Answer
- B.detect
- C.delay
- D.decide
Deter is a verb meaning to prevent or discourage someone from acting, usually through fear of a consequence, as a locked gate deters trespassers; 'discourage' captures that meaning precisely. 'Delay' only postpones an action rather than preventing it, and 'decide' and 'detect' are look-alike words built on different roots (de- plus cide/tect) that share only the prefix. The prefix de- ('away, down') plus terrere ('to frighten') is the decoding path.

5. Living on a student budget forced her to be FRUGAL. FRUGAL most nearly means:
- A.hungry
- B.thrifty✓ Answer
- C.cheerful
- D.organized
Frugal is an adjective meaning careful and sparing with money or resources, so 'thrifty' is the closest synonym. The context clue is 'student budget', which points to limited money rather than mood, appetite, or tidiness. 'Organized' is the trickiest distractor because frugal people often plan carefully, but planning is a side effect, not the meaning — on the ASVAB the key must be the closest meaning, not merely a related trait.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge in-context item style; Merriam-Webster, 'frugal' (characterized by or reflecting economy in the use of resources)Report a problem with this question
6. HINDER most nearly means:
- A.announce
- B.obstruct✓ Answer
- C.borrow
- D.assist
Hinder is a verb meaning to make progress difficult or hold something back, as heavy snow hinders traffic; 'obstruct' names the same interference with forward movement. 'Assist' is the reverse and is included because the ASVAB rewards checking connotation — a helping word cannot be the key for a blocking word. 'Borrow' and 'announce' share no meaning with the target.

7. The judge was LENIENT with the first-time offender. LENIENT most nearly means:
- A.puzzled
- B.prompt
- C.strict
- D.merciful✓ Answer
Lenient is an adjective meaning not harsh in judgment or punishment, so 'merciful' is the closest synonym. The context clue 'first-time offender' signals reduced severity, which is exactly the situation the word describes. 'Strict' is the tone-flipped trap: it fits the same topic of judging but carries the opposite charge, and the ASVAB never asks for opposites as an item type.

8. NOVICE most nearly means:
- A.supervisor
- B.expert
- C.beginner✓ Answer
- D.volunteer
Novice is a noun naming a person new to an activity, and all four options are nouns naming people, so the decision rests on meaning alone: 'beginner' is the exact match. The Latin root nov- ('new') is the decoding clue, the same root found in novel and renovate. 'Expert' is the reverse, and 'supervisor' and 'volunteer' describe roles that say nothing about experience level.

9. The instructions were so OBSCURE that no one could follow them. OBSCURE most nearly means:
- A.official
- B.unclear✓ Answer
- C.lengthy
- D.expensive
Obscure has several senses — little known, dim, or hard to understand — and the context decides which one is tested here. Because the sentence says no one could follow the instructions, the sense is 'hard to understand', making 'unclear' the key. 'Lengthy' is a plausible reason instructions might fail but is not what the word means; this is the classic multiple-meaning trap the ASVAB uses in-context items to test.

10. TEDIOUS most nearly means:
- A.delicate
- B.boring✓ Answer
- C.dangerous
- D.temporary
Tedious is an adjective describing something long and dull enough to be wearying, such as copying numbers by hand; 'boring' is the closest synonym. 'Delicate' is a near-miss distractor because tedious work is often painstaking, but painstaking describes required care while tedious describes the tiresome dullness. 'Temporary' merely looks similar at the start of the word and shares no root with tedious.

11. A good sentry stays VIGILANT through the entire watch. VIGILANT most nearly means:
- A.silent
- B.watchful✓ Answer
- C.obedient
- D.energetic
Vigilant is an adjective meaning alertly watching for possible danger, so 'watchful' is the closest match. Every distractor names a trait a sentry might also have, which is why the key must be chosen on meaning rather than on topic fit — a common ASVAB miss. The Latin root vigil ('awake, alert'), also seen in vigil and invigilate, confirms the sense.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge in-context item style; Merriam-Webster, 'vigilant' (alertly watchful especially to avoid danger)Report a problem with this question
12. AMPLE most nearly means:
- A.plentiful✓ Answer
- B.polite
- C.sudden
- D.scarce
Ample is an adjective meaning more than enough in quantity or size, as in ample storage space; 'plentiful' matches that sense of generous supply. 'Scarce' is its reverse and is a deliberate check on connotation, since a positive-charge word cannot be answered by a negative-charge one. 'Sudden' and 'polite' describe timing and manner rather than quantity.

13. She set a BRISK pace on the morning march. BRISK most nearly means:
- A.clumsy
- B.quiet
- C.quick✓ Answer
- D.steady
Brisk means quick and energetic, so applied to a pace it identifies speed; 'quick' is therefore the closest synonym. 'Steady' is the strongest distractor because a march can be both brisk and steady, but steady describes evenness rather than speed, and the ASVAB asks for the closest meaning rather than a compatible one. Note that 'brisk' can also describe cold air as bracing, and the word 'pace' is the context clue that selects the speed sense.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge in-context item style; Merriam-Webster, 'brisk' (keenly alert, lively; marked by speed)Report a problem with this question
14. CORDIAL most nearly means:
- A.curious
- B.truthful
- C.friendly✓ Answer
- D.formal
Cordial is an adjective describing a warm and sincerely welcoming manner, so 'friendly' is the closest synonym. 'Formal' is the most seductive distractor because cordial greetings often occur in formal settings, but formality refers to observing convention, which can be cold; the ASVAB frequently pairs a right-topic wrong-charge option like this. The Latin root cord ('heart'), the same root as in accord, points to warmth of feeling.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge synonym item style; Merriam-Webster, 'cordial' (warmly and genially affable)Report a problem with this question
15. DILIGENT most nearly means:
- A.hardworking✓ Answer
- B.agreeable
- C.talented
- D.impatient
Diligent is an adjective describing steady, careful effort in work or study, so 'hardworking' is the closest synonym. 'Talented' is the near-miss distractor: it also praises a worker, but it names natural ability rather than sustained effort, and diligence is precisely about effort a person supplies. Choosing between two flattering options by asking which one names effort versus ability is the elimination move the ASVAB rewards.

16. The engineer said the plan was FEASIBLE with the current budget. FEASIBLE most nearly means:
- A.profitable
- B.workable✓ Answer
- C.required
- D.temporary
Feasible means capable of being done or carried out, so 'workable' is the closest synonym. The context clue 'with the current budget' frames the question as whether the plan can be accomplished under a constraint, which is exactly what feasibility asks. 'Profitable' is a money-flavored distractor pulled in by the word budget, but a feasible plan may still lose money — feasibility concerns possibility, not payoff.

17. MEAGER most nearly means:
- A.average
- B.bitter
- C.scanty✓ Answer
- D.generous
Meager is an adjective meaning deficient in quantity or quality, as in a meager portion of food; 'scanty' names that same insufficiency. 'Average' is the near-miss trap because both suggest 'not a lot', but average means ordinary or middling while meager means clearly too little, and the ASVAB requires the closest match rather than the roughly compatible one. 'Generous' carries the opposite charge and 'bitter' describes taste.

18. It was PRUDENT to check the weather before sailing. PRUDENT most nearly means:
- A.required
- B.sensible✓ Answer
- C.unusual
- D.fearful
Prudent is an adjective describing careful good judgment about the future, so 'sensible' is the closest synonym. The context clue 'before sailing' shows the action is a wise precaution taken in advance, which is the heart of prudence. 'Fearful' is the connotation trap: prudence is calm foresight, not anxiety, and a positive-charge word cannot be answered by a negative-charge one.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge in-context item style; Merriam-Webster, 'prudent' (marked by wisdom or judiciousness; shrewd in the management of practical affairs)Report a problem with this question
19. TRANQUIL most nearly means:
- A.empty
- B.chilly
- C.distant
- D.peaceful✓ Answer
Tranquil is an adjective meaning free from disturbance or agitation, as a tranquil lake at dawn; 'peaceful' is the closest synonym. 'Empty' and 'distant' are scene-setting distractors that often appear in the same descriptions but name absence and remoteness rather than calm, and 'chilly' names temperature. Options that merely fit the same picture as the target word are the most common wrong choice on Word Knowledge.

20. The sergeant's STERN warning ended the argument. STERN most nearly means:
- A.rear
- B.written
- C.sudden
- D.severe✓ Answer
Stern has two unrelated common senses: as a noun it is the rear of a ship, and as an adjective it means harsh or strict. Because it modifies the noun 'warning' here, the tested sense must be the adjective, so 'severe' is the key and 'rear' is the wrong part of speech as well as the wrong sense. Checking the grammatical slot the word occupies is the fastest way to defuse a multiple-meaning item.
Source: officialasvab.com ASVAB Fact Sheet (Apr 2025), Word Knowledge in-context item style ('correct meaning of a word presented in context'); Merriam-Webster, 'stern' adj. (expressive of severe displeasure; hard, severe) vs. 'stern' n. (the rear end of a boat)Report a problem with this question
