Origin: 1595–1605; (< French conniver) < Latin co(n)nīvēre to close the eyes in sleep, turn a blind eye, equivalent to con-con- + -nīvēre, akin to nictāre to blink (compare nictitate)
c.1600, from L. connivere, also conivere "to wink," from com- "together" + base akin to nictare "to wink," from PIE base *knei-gwh- "to bend." Hence, "to wink at (a crime), be secretly privy."
