Inherited from Middle English rouble, rubel, robel, robeil, from Anglo-Norman robel (“bits of broken stone”). Presumably related to rubbish, originally of same meaning (waste material, bits of stone, rubble). Ultimately presumably from Old Norse rubba (“to huddle, crowd together, heap up", possibly also "to rub, scrape”), from Proto-Germanic rubbōną (“to rub, scrape”), related to Proto-Germanic reufaną (“to tear”), raubōną (“to rob, steal, plunder”), perhaps via Old French robe (English rob (“steal”)) in sense of “plunder, destroy”; see also Middle English, Middle French -el.
Typically functions as a collective noun for the mass of debris; rarely used in the plural.
