An Etymological Dictionary of the German Language/Jauche

by Friedrich Kluge

Jauche, f., ‘filthy liquid, first occurs in early ModHG., introduced into HG. from a MidG. and LG. variant, jûche. It is based on a Slav. word for ‘broth, soup,’ which deteriorated in sense when borrowed; e.g. Pol. jucha, ‘broth’ (cognate with Lat. jûs, Sans. yûšan, ‘broth’).
