The word "coup" originates from Old French colp (modern French coup), meaning "a blow" or "a strike," derived from Latin colaphus (a blow with the fist). Over time, it evolved metaphorically to denote a sudden, decisive action—particularly in politics (e.g., coup d'état). The term retains its core sense of a swift, impactful act across contexts.
