Compare Polish, Latvian zupa, Yiddish זופּ (zup). Likely from the Polish, which is itself from German Suppe, from Old French souppe, sope. Itself from either Middle Low German (cf., e.g., sūpen “to drink; to eat with a spoon,” German saufen “to drink; to booze”) or from Late Latin suppa (“sopped bread”), from Proto-Germanic *supô. Ultimately from the same Proto-Indo-European stem (*seu-, *sū- “juice; moisture”) as the English verb suck.
