Etymology

Origin of accomplice

First recorded in 1475–85; a(c) of uncertain origin + late Middle English complice, from Middle French, from Medieval Latin complici- (stem of complex ) “partner”; complex

Explanation

An accomplice is a cooperator or participator, commonly in criminal acts. So you’re an accomplice to the gas station robbery if you distracted the store manager while your partner in crime raided the registers for cash. Coming from the Old French word complice, which means “a confederate,” an accomplice is an ally or partaker, sometimes in wrongdoing. Novelist Saul Bellow famously said that "when we ask for advice, we are usually looking for an accomplice.” What he means, in more direct terms, is that we run potential plans by others because we're looking for approval or someone to go along with us, not because we truly want their opinion.
