(third-person singular simple present connives, present participle conniving, simple past and past participle connived)
Circa 1600, from French conniver, from Latin connīveō (“wink”), or directly from Latin, from com- (“together”) + base akin to nictō (“I wink”), from Proto-Indo-European *knei-gwh- (“to bend”). See also English nictate (“to wink”), from same Latin base.
Sense comes from extension of “to wink” into “to wink (at a crime), to be privy”.
