köken: Vulgar Latin *barilus or *barillus, perhaps via Old French baril, as a direct inheritance would yield *barilo. Stated by Vocabolario etimologico della lingua italiana to be of Celtic origin, however a more likely origin is Proto-West Germanic *baril, from Proto-Germanic *barilaz, cf. the etymology for Old French baril.
aile: barilaio, barilotto, bariletto, imbarilare, raschiare il fondo del barile, scaricabarile, scaricabarili
köken: From earlier fuste (“type of wine barrel”), from Middle Dutch fuust (“barrel”), borrowed from Old French fust (“wine barrel, piece of wood”), from Latin fusta, fustum (“block of wood, barrel”), from earlier fustis (“cludgel”). Cognate with English fust.
köken: From Proto-Indo-European *kewp- (“a hollow”), perhaps of substrate origin. Cognate with Old English hȳf (modern English hive), Sanskrit कूप (kūpa, “well, hollow, vat”), Ancient Greek κύπελλον (kúpellon, “beaker, goblet”).
aile: cuppa, cūpula
