zumo m. (Noun) "juice (from plants)"
13th cent. Probably borrowed from Arabic zūm "juice," which was borrowed from Ancient Greek, although it seems that at the time zūm was used only in Arabic spoken Egypt and Syria, so zumo may have been taken directly from Ancient Greek. Either way, the ultimate source is Ancient Greek ζωμός (dzomós) "sauce," "soup." Of unknown origin.
