I have a practice test for the 2016 AFOQT exam. One section is "Word Knowledge" wherein you're given a word in all caps, then you select the word with the most similar meaning from 4 choices.
I purchased a practice guide where one of the practice questions is as follows:
INSINUATE A. infiltrate B. introduce C. proclaim D. abbreviate
I didn't see a good answer, but I put "C". Their answer key has the answer as "A".
There is no published Erratum, so I want to make sure that defensiveness of my answer is not clouding my judgement.
The definition I have for "insinuate" is:
: to say (something, especially something bad or insulting) in an indirect way
The definition I have for "infiltrate" is:
: to cause (someone) to secretly enter or join a group, organization, etc.
