IPA: //prɪˌvɛrɪˈkeɪʃən//
KK: /prɪˌvɛrɪˈkeɪʃən/
The act of avoiding the truth or being deliberately unclear in order to mislead or deceive.
His prevarication during the interview made it clear that he was hiding something.
Prevarication is formed from "pre-" (meaning before) and "varicare" (meaning to straddle or to evade). The word describes the act of evading the truth or straddling between two positions, often in a deceptive manner.
Think of someone who is 'straddling' ('varicare') between two truths, 'before' ('pre-') making a statement — that's why prevarication means to avoid telling the truth.
