brake: There are two distinct words brake in English. By far the older is that meaning ‘overgrown area, thicket’ [OE]. Its source is uncertain, but it has been speculated that it is ultimately related to break, its original meaning perhaps having been something like ‘broken wood’. Brake ‘decelerating mechanism’ [15] meant ‘bridle’ for stopping a horse’s progress, and may have been borrowed from Middle Dutch braeke, a word which was used for a wide variety of crushing implements but also apparently for a ring put through the nose of a draught ox. There may well be some ultimate connection with break here too. => break[brake etymology, brake origin, 英语词源]
