innocence

A Roman could say innocens about someone who wasn’t causing trouble — not plotting, not injuring, not staining the room with moral mud. That’s the neat trick here: Latin in- means “not,” while nocere means “to hurt,” so the word is literally built out of a refusal to wound. The same family gives us innocuous, noxious, and the rarer nocent, so you can hear the old harm-vocabulary still rattling around inside the modern word. By the 12th century Old French had inocence, and Middle English took it over in the 1300s, where it could mean purity, chastity, or simply the lack of legal guilt. In other words, innocence is not a blank slate so much as a shield: the ancient promise that nothing in you has drawn blood.
