Complicit and Its Accomplices

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, “helping to commit a crime or do wrong,” describes individuals who are “folded together” metaphorically. Complicity and the its cousins accomplice, complicitous, and complice are all part of this gang.

Complicare, in a second of its Latin senses, “to twist together,” is the root of another English word, complicate, which originally meant “to unite intimately by intertwining.” In this case, the idea of things “twisted together” makes sense as an image of something composed of many elements, that is, something complicated. The -pli- of these words is from plicare (“to fold”), which is also the root of ply, the verb meaning “to twist together” or the noun meaning “one of several layers.”

Other words that derive from plicare are also illuminated by their etymologies: explicit “revealed without ambiguity” ultimately comes from Latin explicare, meaning “to unfold,” while implicit, meaning “implied,” descends from a Latin verb whose roots literally mean “to fold in.”

Etymology

back-formation from complicity, probably after explicit, implicit

Note: Strictly speaking, the derivation of complicit from complicity is not a back-formation, unless -y is taken as the suffix -y entry 2, which seems unlikely. The derivation presumably depends on the acceptability of complicit beside the established words explicit and implicit. A regularly formed adjective derivative of complicity is complicitous.
