The word "rotation" traces back to the Latin rotatio, derived from rota ("wheel"). The core idea of circular movement persisted through Old French (rotacion) into Middle English, eventually solidifying as "rotation" in modern English. The suffix -ation systematically converts verbs (e.g., rotate) into nouns denoting processes, emphasizing the cyclical nature of the action.

The mechanic checked the wheel rotation for balance.
