An Etymological Dictionary of the German Language/Annotated/Wurst
Wurst, feminine, ‘sausage, pudding, roll, pad,’ from the equivalent Middle High German and Old High German wurst (Middle German and Dutch worst), feminine. This specifically German word is rightly regarded as a derivative of the Aryan root wert, ‘to turn, wind’ (see werden and Wirtel); hence Wurst (base wrtti, wrtsti), literally ‘turning.’
