- start (v.)
- Old English *steortian, *stiertan, Kentish variants of styrtan "to leap up" (related to starian "to stare"), from Proto-Germanic *stert- (source also of Old Frisian stirta "to fall, tumble," Middle Dutch sterten, Dutch storten "to rush, fall," Old High German sturzen, German stürzen "to hurl, throw, plunge"), of uncertain origin. According to Watkins, the notion is "move briskly, move swiftly," and it is from PIE root *ster- (1) "stiff."
From "move or spring suddenly," sense evolved by late 14c. to "awaken suddenly, flinch or recoil in alarm," and by 1660s to "cause to begin acting or operating." Meaning "begin to move, leave, depart" (without implication of suddenness) is from 1821. The connection probably is from sporting senses ("to force an animal from its lair," late 14c.). Transitive sense of "set in motion or action" is from 1670s; specifically as "to set (machinery) in action" from 1841.
