Origen

mid 16th century: from Latin rotatio(n-), from the verb rotare (see rotate).

More
  • The Latin rota ‘wheel’ and the verb from it rotare ‘to turn’ is the source of rotation and related words. These include rotund (late 15th century) for something well rounded, and rotunda (early 17th century) for a round building or room. It is an alteration of Italian rotonda (camera) ‘round (chamber)’. Round (Middle English) comes from the same source via French. The worldwide charitable society of business people formed in 1905 known as Rotary International owes its name to the fact that its members hosted events in rotation.
