Complicit is a relatively recent addition to English vocabulary, arriving in the mid-1800s. It is a back-formation from complicity “association or participation in a wrongful act,” which came straight from a French word of the same meaning, complicité, in the 1600s. The oldest English word in this family is the now-obsolete complice (pronounced /COMP-liss/)—defined as “an associate or accomplice especially in crime”—which dates back to the 1400s, when it came from French. These words ultimately derive from the Latin verb meaning “to fold together,” complicare, formed by combining com- (meaning “with,” “together,” or “jointly”) and the verb plicare, meaning “to fold.”
This literal meaning evolved into a figurative one. The definition of complicit, describes individuals who are “folded together” metaphorically. Complicity and the its cousins accomplice, complicitous, and complice are all part of this gang. This word is adopted from French to English.. Also, the Latin verb meaning “to fold together,” complicare, formed by combining com- (meaning “with,” “together,” or “jointly”) and the verb plicare, meaning “to fold.”
