Etymology 1

From Middle English jumpen (to walk quickly, run, jump), probably of Middle Low German or North Germanic origin, ultimately from Proto-Germanic *gempaną, *gembaną (to hop, skip, jump), from Proto-Indo-European *gʷʰemb- (to spring, hop, jump). The OED instead suggests an imitative origin. Related to jumble.
