ASVAB Word Knowledge practice
Word Knowledge (WK) asks you to pick the meaning of a word in context or the best synonym, and it counts toward the AFQT. The 12 questions below include six taken from the AptiStep app’s vocabulary bank.
Last updated · Published by Certloom Learning · Written by Certloom Learning for AptiStep. Not real ASVAB questions and not an official word list.
What does ASVAB Word Knowledge test?
The official description: “Ability to select the correct meaning of words presented in context and to identify the best synonym for a given word” (Official ASVAB: What to Expect (checked 2026-11-12)). Both skills reward reading the whole sentence before choosing.
How is Word Knowledge tested on the CAT-ASVAB and on paper?
On the computer version the official table lists 15 scored questions and up to 15 unscored tryout questions, with a time limit of 9 minutes without tryout questions or 18 minutes with them. On paper it has 35 questions in 11 minutes. Source: Official ASVAB: What to Expect (checked 2026-11-12).
On the computer version Word Knowledge has 15 scored questions in 9 minutes, so you have well under a minute per word. Knowing the word on sight is faster than working it out.

In “The instructions were concise, giving every necessary detail in only three sentences,” concise most nearly means:
- brief and clear
- difficult to follow
- repeated often
- incomplete
Show answer and explanation
Answer: A. brief and clear
“Every necessary detail” rules out incomplete. “Only three sentences” points to brief. Concise means expressing what is needed in few words.
In “The path was obstructed by a fallen branch,” obstructed most nearly means:
- measured
- blocked
- repaired
- widened
Show answer and explanation
Answer: B. blocked
A fallen branch prevents movement along the path, so blocked fits. Substitute it into the sentence: “The path was blocked by a fallen branch.”
In “Fresh water was scarce during the long dry period.” the word scarce most nearly means:
- expensive
- polluted
- warm
- limited
Show answer and explanation
Answer: D. limited
Scarce means not available in sufficient quantity. Substituting “limited” keeps the sentence meaning; the other choices change it.
In “The meticulous clerk checked every entry twice.” the word meticulous most nearly means:
- curious
- confident
- thorough
- speedy
Show answer and explanation
Answer: C. thorough
Meticulous means very careful about small details. Substituting “thorough” keeps the sentence meaning; the other choices change it.
In “He was reluctant to discard a tool that might be repaired.” the word reluctant most nearly means:
- required
- hesitant
- unable
- eager
Show answer and explanation
Answer: B. hesitant
Reluctant means not willing or eager to do something. Substituting “hesitant” keeps the sentence meaning; the other choices change it.
In “Please verify the total before sending the invoice.” the word verify most nearly means:
- confirm
- estimate
- change
- calculate roughly
Show answer and explanation
Answer: A. confirm
Verify means check that something is true or correct. Substituting “confirm” keeps the sentence meaning; the other choices change it.
In “The concise notice gave the date and location in two sentences.” the word concise most nearly means:
- vague and lengthy
- loud and urgent
- formal and old
- brief and clear
Show answer and explanation
Answer: D. brief and clear
Concise means expressed clearly with few unnecessary words. Substituting “brief and clear” keeps the sentence meaning; the other choices change it.
In “Closing the door helped diminish the noise.” the word diminish most nearly means:
- produce
- repeat
- reduce
- measure
Show answer and explanation
Answer: C. reduce
Diminish means make or become smaller. Substituting “reduce” keeps the sentence meaning; the other choices change it.
“Water was scarce, so each person received only a small amount.” What does scarce mean here?
Show answer and explanation
Answer: In short supply
Small allocations point to limited availability. “Scarce” describes how little is available, not the water’s temperature or quality. Substitute “in short supply” to check the meaning.
“Her method was meticulous: she checked each measurement twice.” What does meticulous mean?
Show answer and explanation
Answer: Very careful and precise
Repeatedly checking measurements gives evidence of attention to detail. It does not imply that the work was quick or improvised.
“The temporary walkway will be removed when the permanent bridge opens.” What does temporary mean?
Show answer and explanation
Answer: Intended to last for a limited time
The planned removal contrasts with the permanent bridge. The word describes duration; it does not itself tell you whether the walkway is safe or well built.
“After finding the error, Luis revised the report before sending it.” What does revised mean?
Show answer and explanation
Answer: Changed to correct or improve it
The identified error provides the reason for changing the report. “Revised” does not mean merely reread, discarded or sent unchanged.
How should I study ASVAB vocabulary?
Learn a word with a plain definition and a sentence, then test it by substitution: put your chosen meaning in place of the word and see whether the sentence still makes sense. Lists alone fail when a word has several meanings. See the context lesson.
Frequently asked questions
Is there a required ASVAB vocabulary list?
The official ASVAB site does not publish one. Any list, including the app’s, is a study aid.
What if I do not know the word?
Use the sentence for clues, eliminate choices that clash with it, and answer. See the strategy notes on the official preparation page.
