Anglo-Norman *robel (“bits of broken stone”). Presumably related to rubbish, originally of same meaning (bits of stone). Ultimately presumably from Proto-Germanic *raub- (“to break”), perhaps via Old French robe (English rob (“steal”)) in sense of “plunder, destroy”; see also Middle English, Middle French -el.
