Definition of rotational

The word "rotational" has its roots in Latin. The Latin word "rotare" means "to rotate" or "to turn", and it's related to the word "rotundus", which means "round" or "curved". From Latin, the word "rotare" was borrowed into Middle English as "rotaten", which meant "to turn or move in a circle". The adjectival form "rotational" emerged in the 16th century, initially used to describe something that rotates or turns around a central point. Over time, the meaning of "rotational" expanded to include the concept of periodic or cyclical movement, such as the rotation of a planet around its axis or the rotation of an object around a fixed point. Today, "rotational" is used in various fields, including physics, engineering, and biology, to describe the movement or motion of objects, systems, or organisms that involve rotation or cyclical activity.
