An Etymological Dictionary of the German Language/Quappe

by Friedrich Kluge

Quappe, f., ‘eel-pout, tadpole,’ ModHG. only, from LG. in which the OLG. word quappa occurs (comp. Du. kwab); the latter is primit. allied to OPruss. gabawo, ‘toad,’ OSlov. żaba (from the prim. form *gêba), ‘frog.’ The assumption that the word is borrowed from Lat. capito is less probable.
