type of sausage, 1904, from German Bratwurst, from wurst + Brät "lean meat, finely chipped calf or swine meat," from Old High German brato (12c.), from Proto-Germanic *bred-on- "roast flesh" (source also of Old English bræd "meat, flesh;" compare brawn), from PIE root *bhreu- "to boil, bubble, effervesce, burn." German folk etymology derives Brät from braten "to roast, bake, broil, grill;" more likely both are from the same ancient source.
