ASVAB Word Knowledge: practice, strategy and a free drill

Word Knowledge (WK) asks you to pick the word closest in meaning to another, alone or in a sentence: 15 questions in 9 minutes on the CAT and 35 in 11 minutes on paper, the fastest pace of the four AFQT subtests at about 19 seconds a question. With Paragraph Comprehension it makes Verbal Expression (VE), which counts double in the AFQT.

What does ASVAB Word Knowledge test?

The official description is the best synonym and word meaning in context. Some questions give a word on its own ("ABUNDANT most nearly means"); others put it in a sentence and ask what it means there. Either way you are matching meanings, not definitions word for word.

It is the quickest of the four AFQT subtests on the paper ASVAB: 35 questions in 11 minutes leaves about 19 seconds each, so there is no time to puzzle over a word. You either know it, can take it apart, or guess and move on. The CAT is gentler at about 36 seconds a question.

WK is half of Verbal Expression (VE), which counts twice in the AFQT, so it carries as much weight as Arithmetic Reasoning. VE also sits inside the Army GT, CL, CO, OF, SC and ST line scores, most Navy rating sums, the Air Force General and Administrative composites, and the Marine Corps GT and CL.

See which jobs ask for which scores, branch by branch: Army jobs, Navy jobs, Air Force jobs, Marine Corps jobs.

Which word roots help most on ASVAB Word Knowledge?

Roots and prefixes let you take apart a word you have never seen. These fifteen cover a large share of test-style vocabulary.

Common roots and prefixes, with an example (our list)
Part	Meaning	Example
bene-	good, well	benefit, benevolent
mal-	bad	malfunction, malicious
in-, im-, un-	not	inaudible, impartial
pre-	before	precede, predict
re-	again, back	revise, retract
sub-	under	submerge, subordinate
trans-	across	transmit, transfer
aud	hear	audible, auditorium
dict	say	contradict, dictate
spec, spect	look	inspect, spectator
port	carry	portable, transport
cred	believe	credible, incredulous
vor	eat	voracious, herbivore
-ous, -ive	full of, tending to	tenacious, decisive
-ible, -able	can be	audible, durable

Roots narrow the options rather than prove the answer. Inaudible is "not" + "hear" + "can be", which rules out loud, clear and unclear at once.

What do ASVAB Word Knowledge questions look like?

Like these 6, which we wrote in the style of the official description: the first two are worked open, the rest hide the answer until you try. None is a real ASVAB question.

ASVAB-style question 1 · Synonym
TENACIOUS most nearly means
1. Apersistent
2. Bcareless
3. Cgentle
4. Dnervous
Worked answer
A: persistent. Tenacious means holding on firmly and not giving up, which is persistent.
1. Think of a phrase you have heard: a tenacious defender, a tenacious grip.
2. Both mean holding on and not letting go.
3. Persistent is the only option with that meaning.
The trap: Nervous, because tenacious sounds like "tense". Sound is a poor guide; use a phrase you know.
ASVAB-style question 2 · Synonym
His reply was TERSE.
1. Abrief
2. Bangry
3. Cconfused
4. Dpolite
Worked answer
A: brief. Terse means using few words: brief.
1. Terse describes length: a terse reply is a short one.
2. Angry and polite describe tone; confused describes clarity.
3. Brief matches length.
The trap: Angry. Terse replies can come across as rude, so the mood option is tempting, but the word itself is about length.
ASVAB-style question 3 · Synonym
MITIGATE most nearly means
1. Alessen
2. Bworsen
3. Cexplain
4. Ddelay
Show the worked answer
A: lessen. To mitigate is to make something less severe.
1. Recall a use: "steps to mitigate the risk", "mitigating circumstances".
2. Both reduce how bad something is.
3. Lessen fits; worsen is the opposite.
The trap: Worsen. When you half-know a word, the opposite meaning is often the option that feels familiar. Check the direction.
ASVAB-style question 4 · Synonym
There was AMPLE time to finish the job.
1. Aplentiful
2. Blittle
3. Cwasted
4. Dexact
Show the worked answer
A: plentiful. Ample means more than enough: plentiful.
1. Replace the word with each option and read the sentence.
2. "Plentiful time to finish" keeps the meaning; "little time" reverses it.
3. Wasted and exact change the sense.
The trap: Exact, from reading "ample" as "a sample" or "precise". Plug each option into the sentence.
ASVAB-style question 5 · Word in context
The pilot remained COMPOSED during the emergency landing.
1. Acalm
2. Bwritten
3. Calert
4. Dsilent
Show the worked answer
A: calm. Composed describing a person means calm and in control.
1. Composed has two meanings: put together (a composed song) and calm.
2. A pilot during an emergency is a person, so the "calm" meaning fits.
3. Alert and silent describe other things; calm is the match.
The trap: Written. It is a real meaning of composed, but not of a person in an emergency. Context questions test the second meaning on purpose.
ASVAB-style question 6 · Word parts
INAUDIBLE most nearly means
1. Aimpossible to hear
2. Btoo loud
3. Cunclear in meaning
4. Dnot allowed
Show the worked answer
A: impossible to hear. In- (not) + aud (hear) + -ible (can be): cannot be heard.
1. Split the word: in + aud + ible.
2. "Not" + "hear" + "can be" gives "cannot be heard".
3. Only the first option says that.
The trap: Unclear in meaning, which describes something you can hear but cannot understand. Inaudible is about hearing at all.

How do you get a better ASVAB Word Knowledge score?

Before you look at the options, say what the word means to you. Then pick the closest option. It stops similar-looking words pulling you off course. The rest of our method is below.

Our method, in order of how much it usually helps

Answer in your own words first
Before you look at the options, say what the word means to you. Then pick the closest option. It stops similar-looking words pulling you off course.
Use a phrase you know
Many words you cannot define on their own you know in a phrase: "a tenacious grip", "mitigating circumstances". Recall the phrase and the meaning follows.
Plug the option into the sentence
When the word is in a sentence, read the sentence again with each option in its place. The right one keeps the meaning; the others change it.
Take the word apart
Prefix, root, suffix. The table above narrows most unknown words to one or two options.
Keep moving: about 19 seconds on paper
Word Knowledge rewards speed. If you do not know the word after one pass, guess the option that best fits any part you do recognise, and move on.
Learn words in sentences, not lists
Fifteen new words a day with one sentence each beats a hundred definitions read once. You remember words you have used.

What are the most common ASVAB Word Knowledge mistakes?

Sound-alikes: tenacious is not tense, ample is not a sample, prosaic is not prose. If you are matching by sound, slow down.

The traps we see most often, and the fix

Sound-alikes
Tenacious is not tense, ample is not a sample, prosaic is not prose. If you are matching by sound, slow down.
Tone instead of meaning
Terse, curt and blunt sound rude but are about length or directness. Pick the option that matches the meaning, not the mood.
The opposite
Test writers often include the antonym. If you half-know a word, check you have not picked its opposite.
The wrong meaning of a word with two
Composed, sound, novel, grave. When a word is in a sentence, the sentence tells you which meaning is being tested.
Overthinking easy words
Some questions are easy on purpose. If the obvious answer fits, take it and save the time.

How should you study for ASVAB Word Knowledge in a week?

Start with the free drill to find your weak spots, spend five days on them, then retake the drill. Twenty to forty minutes a day is enough to see a change.

A 7-day Word Knowledge plan (ours)
Day	What to do
Day 1	Take the free drill below. List every word you missed or guessed.
Day 2	Learn the fifteen roots above with two example words each. Then 15 new words, one sentence each.
Day 3	15 new words. Review days 1 and 2. Practise the plug-in method on 20 context questions.
Day 4	15 new words. Read a news article and underline five words you could not define; look them up.
Day 5	A timed set at the paper pace (19 seconds a question). Note any you could have taken apart.
Day 6	15 new words. Quiz yourself on every word from the week, in sentences.
Day 7	Retake the drill. Keep the 15-a-day habit until test day: it compounds.

Then put it together: the how to pass the ASVAB guide plans all four AFQT subjects, the free ASVAB-style practice test gives an estimated AFQT, and what is a good ASVAB score shows what each branch asks for. The other subtest guides: Arithmetic Reasoning, Paragraph Comprehension, Mathematics Knowledge.

What kind of words are on ASVAB Word Knowledge?

Everyday and moderately advanced vocabulary of the kind found in newspapers and textbooks, asked as synonyms or as meaning in a sentence. There are no spelling or grammar questions.

Is there a list of ASVAB Word Knowledge words?

Does Word Knowledge count more than other subtests?

Should I guess on Word Knowledge?

On paper, always: wrong answers cost nothing and blanks count as wrong. On the CAT, answer every question you reach in the time, but do not click through unanswered ones at the end, because the CAT scores those as random guesses.
