Where does dud come from?

From Middle English dudde (“cloak, mantle, kind of cloth; ragged clothing or cloth”), from Old English *dudda (attested only as personal name Dudda, part of modern English Dudley), akin to Old Norse dúði (“swaddling clothes”), Low German dudel. Possibly borrowed from the Old Norse word and related to dýja (“to shake, tremble”).
