Inherited from Middle English rubben, of unknown origin; possibly ultimately from Proto-Germanic rubbōną, related to reufaną (“to tear”). Cognate with Saterland Frisian rubje (“to rub, scrape”), German Low German rubben (“to rub”), Low German rubblig (“rough, uneven”), Dutch robben, rubben (“to rub smooth; scrape; scrub”), Danish rubbe (“to rub, scrub”), Icelandic and Norwegian rubba (“to scrape”). More at reave. Compare typologically Latin fricō < friō < Proto-Indo-European *bʰreyH- (whence also Russian брить (britʹ, “to shave”)).
