crush: [14] The emergence of crush is something of a mystery. English borrowed it from Old French croissir, but it is not clear where Old French got it from. Some consider it to be of Romance origin, postulating a hypothetical Vulgar Latin *cruscīre to account for it, but others suggest that Old French may have borrowed it from Germanic, pointing to the similarity of Middle Low German krossen ‘crush’.
