An Etymological Dictionary of the German Language/Bottich
Bottich, m, ‘tub, vat,’ from the equiv. MidHG. botech, boteche, m, OHG. botahha, f.; it is probably related to the cognates of Bütte; comp. further AS. bodig, E. body, OHG. budeming, perhaps also ModHG. Boden?. Considering the deriv. of ModHG. Bischof from episcopus, we may assume that Bottich is allied to Lat.-Gr. apotheca; comp. Ital. bottega (Fr. boutique).
