First attested in 1890. Borrowed from German Wurst (“sausage, wurst”), from Middle High German wurst, from Old High German wurst, from Proto-West Germanic *wursti (“something turned or twisted”), from Proto-Indo-European *wert-, *werd- (“to turn”).
Akin to Old Saxon worst (“wurst”), Old English weorþan (“to turn, become”). Doublet of wors. Unrelated to worsted (“type of yarn”). More at worth (“to be, become, betide”).
