词源

From Middle English *swarf, *swerf, from Old English ġeswearf, ġesweorf (“iron filings; rust”) and/or Old Norse svarf (“metallic dust”), both from Proto-Germanic *swarbą (“that which is rubbed off; shavings”), from Proto-Germanic *swerbaną (“to mop, wipe; to rub off”); see further at swerve. The word is cognate to Old English sweorfan (“to rub, scour; to file”).
