gait n.

c. 1300, gate "a going or walking, departure, journey," earlier "way, road, path" (c. 1200), from a Scandinavian source (compare Old Norse gata "way, road, path"), from Proto-Germanic *gatwon "a going" (source also of Old High German gazza "street," German Gasse "a way, road," Gothic gatwo), perhaps from PIE *ghe- "to release, let go." Meaning "manner of walking, carriage of the body while walking" is from mid-15c. Modern spelling developed before 1750, originally in Scottish. Related: Gaited.
