An Etymological Dictionary of the German Language/Kumpf
Appearance
Kumpf, m., ‘basin, bowl,’ from MidHG. kumpf, m., ‘vessel’; comp. LG. kump. A MidLat. cumpus as the source of the G. word does not exist; MidLat. cumba, cumbus, have too no such meaning as Kumpf, hence they cannot be adduced to explain the dial. ModHG. Kumme, ‘deep bowl.’ Kumme and Kumpf are more probably genuine Teut. words, and allied to AS. cumb and the equiv. E. coomb.
