Etymology

"Rev" is a clipped form of "revolution," specifically referring to the rotational movement of an engine. The term emerged in early 20th-century automotive slang, where "rev up" meant to increase engine speed (revolutions per minute, or RPM). The abbreviation retains the core idea of circular motion but simplifies it for colloquial use.
