whip: [13] Whip was originally a verb, meaning ‘move quickly’. It was probably borrowed from Middle Low German or Middle Dutch wippen ‘vacillate, swing’, which in turn went back to the prehistoric Germanic base *wip- ‘move quickly’ (source also of English wipe). And *wip- itself was descended from Indo-European *wib-, from which English gets vibrate. Wafer, weave, web, etc come from variants of the same base. The application of whip to a ‘flexible implement for lashing’ is first recorded in the 14th century. => vibrate, weave, wipe
