An Etymological Dictionary of the German Language/Bücking

by Friedrich Kluge

Bücking, m., ‘bloater’ (also Bückling, based on Bückling, ‘bow,’ from biegen), from the equiv. MidHG. and MidLG. bückinc; comp. Du. bokking, which is probably a deriv. of Bock, Du. bok, ‘hircus’; in fact, the fish is also called boxhorn (bockshorn) in MidDu.
