Etymology From the term jump (“short coat”) + -er, originally in sailors' jargon, ultimately of uncertain origin. Jump is possibly from Scottish English jupe (“man's loose jacket or tunic”), from Middle English juype, gype, joupe, from Old French jupe, juppe, from Arabic جُبَّة (jubba); see also jibba. Cognate with Middle Low German jōpe, gōpe (“waistcoat, jacket”), German Joppe (“jacket”). Alternatively, perhaps derived from jump.
