duvet

Origin

From French duvet, from Middle French duvet, from Old French duvet (“down, the feathers of young birds”), alteration of dumet, dumect, which in turn derives from dum, dun (“down, feathers”), from Old Norse dúnn (“down, down feather”), from Proto-Germanic *dūnaz (“down”), from Proto-Indo-European *dʰewh₂- (“to smoke, fume, raise dust”). Cognate with Icelandic dúnn (“down”), Danish dun (“down”), German Daune (“down”), Dutch dons (“down”). More at down.
