PREVARICATOR — [Noun] One who speaks or acts in an evasive or misleading way to avoid the truth. From Latin praevaricator ("a collusive accuser, one who betrays a cause"), from praevaricari ("to walk crookedly, to collude"), from prae- ("before") + varicare ("to straddle"). Unlike a liar, who plants a blunt falsehood, or an equivocator, who hides in verbal fog, the prevaricator is an architect of obfuscation, laying down a maze of digressions and half-admissions. He is the politician answering a direct question with a rehearsed anecdote, the bureaucrat citing a procedural nuance to obscure a failure, the witness whose memory becomes conveniently selective—a performer whose art is the strategic sidestep, leaving the truth intact yet forever a ghost in the widening space between what was said and what was meant.
