An Etymological Dictionary of the German Language/Annotated/Graupe

Graupe, feminine, ‘peeled grain or barley,’ first occurs in early Modern High German; in the 15th century the compound îs-grûpe, ‘hailstone,’ is recorded. Allied to Swedish grœpe, grjupe, ‘shot,’ as well as Russian krupa, Old Slovenian krupa, ‘crumb,’ Servian krupa, ‘hail, sleet.’ Probably the cognates are native to Slavonic.
