Word Knowledge

The word knowledge portion of the AFOQT measures verbal comprehension by testing your ability to understand written language. You are given 5 minutes to answer 25 questions. For each question you are to choose the answer that means the same as the capitalized word, e.g.:

TACIT

(A) silent

(B) sour

(C) ornament

(D) talkative

(E) pleasing

Rather than spending your time memorizing hundreds or thousands (perhaps tens of thousands) of words that may appear in this section of the test, familiarizing yourself with English prefixes, roots, and suffixes makes better use of your time – and ensures you’ll be prepared come test day!

Ohh, and the answer to the question is: (A), silent.
