Word Origin and History for harnessing



"to put a harness on a draught animal," c.1300, from Old French harneschier, from harnois (see harness (n.)); figurative sense is from 1690s. Related: Harnessed; harnessing.



c.1300, "personal fighting equipment, body armor," also "armor or trappings of a war-horse," from Old French harnois "arms, equipment; harness; male genitalia; tackle; household equipment," of uncertain origin, perhaps from Old Norse *hernest "provisions for an army," from herr "army" (see harry) + nest "provisions" (see nostalgia). Non-military sense of "fittings for a beast of burden" is from early 14c. German Harnisch "harness, armor" is the French word, borrowed into Middle High German. The Celtic words also are believed to be from French, as are Spanish arnes, Portuguese arnez, Italian arnese. Prive harness (late 14c.) was a Middle English term for "sex organs."
