An Etymological Dictionary of the German Language/Annotated/Kotze
Kotze, feminine, ‘coarse cloth,’ from Middle High German kotze, masculine, ‘coarse, shaggy woollen stuff, cover or garment made of it,’ Old High German chozzo, masculine, chozza, feminine; compare Old Saxon cot (tt) ‘woollen cloak, coat’; a specifically German word, wanting in Gothic, Scandinavian, and English. The Romance words mentioned under Kot (1) — French cotte, ‘petticoat,’ Italian cotta — seem to have been borrowed from German, since in Old High German other words belong to the same class, Old High German umbîchuzzi, ‘upper garment,’ umbichuzzen, verb, ‘amicire.’ On the assumption that Kotze is a genuine Teutonic word, some have connected it with Greek βεῦδος (from the root gud), ‘woman's dress.’ Middle English cote, English coat are certainly of Romance origin, Old French cote, Middle Latin cotta. Compare Kutte.
