rotary = rot<turn> + ary<adjective suffix>
- rot (from Latin rota, meaning "wheel" or "turn")
- ary (Latin-derived suffix forming adjectives, indicating "related to")
Etymology Origin:
The word "rotary" traces back to the Latin rota (wheel), reflecting its core idea of circular motion. The suffix -ary was added in Late Latin (rotarius) to denote "pertaining to wheels." Over time, it evolved in English to describe anything involving rotation, from mechanical devices (e.g., rotary engines) to abstract concepts like rotary motion. The logic is straightforward: rot (turn) + ary (related to) = "related to turning."
