Why this word is great
TERGIVERSATOR — [Noun] One who evades straightforward action or speech, especially by repeatedly changing allegiance or position. From Latin tergiversator ("avoider, one who turns his back"), from tergiversatus, past participle of tergiversari ("to turn one's back, to evade"), from tergum ("back") + versari ("to turn oneself"). Unlike an equivocator, who shrouds intent in ambiguous words, or a turncoat, who commits a single, decisive betrayal, the tergiversator is defined by a restless, evasive shuffle, a career of strategic retreats. It is the politician whose platform dissolves with each new poll, the friend whose loyalties pivot on a whispered grievance, the bureaucrat whose signature migrates from form to form, never alighting. We watch, not for a fall, but for the perpetual sidestep—the art of surviving by ensuring one is never quite where the blow lands.
