Word History

Etymology

Noun

Middle English harneys, herneys "equipment of a man-at-arms, body armor, fittings for a draft animal, apparel, baggage," borrowed from Anglo-French herneis, harneis (also continental Old French), probably borrowed from Old Norse *hernest "provisions for an armed force," from herr "host, army" + nest "provisions," going back to Germanic *nesta- (whence also Old English nest "food, provisions," Old High German -nest, in weganest "provisions for a journey"), derivative, with the noun and adjective suffix -to-, from the base of *nesan- "to save, be saved, return safely" — more at harry, nostalgia

Note: The Norse word was presumably assimilated to the French nominal and adjectival suffix -eis (going back to Latin -ēnsis; compare -ese entry 1), so that the compound was resegmented as harn-eis.

Verb

Middle English harneysen, harneyschen, hernessen "to equip with arms or armor, place accoutrements on a horse or ox, dress," borrowed from Anglo-French harneiser, herneiser, hernescher "to make ready, equip" (continental Old French harneschier, herneschier), derivative of harneis "equipment of a man-at-arms, baggage" — more at harness entry 1
