An Etymological Dictionary of the German Language/Annotated/Jauche

by Friedrich Kluge

Jauche, feminine, ‘filthy liquid, first occurs in early Modern High German, introduced into High German from a Middle German and Low German variant, jûche. It is based on a Slavonic word for ‘broth, soup,’ which deteriorated in sense when borrowed; e.g. Polish jucha, ‘broth’ (cognate with Latin jûs, Sanscrit yûšan, ‘broth’).
