- tergiversation (n.)
- turning dishonestly from a straightforward action or statement; shifting, shuffling, equivocation, 1560s, from Latin tergiversationem (nominative tergiversatio) "a shifting, evasion, declining, refusing," from past participle stem of tergiversari "turn one's back on, evade," from tergum "the back" (of unknown origin) + versare "to spin, turn" (see versus).
