calix.

In view of Umbrian skalçeta (“sacrifical vessel”), perhaps from a Proto-Italic *(s)kalik-, from a Proto-Indo-European *(s)kel- (“a kind of vessel”), and compared with Ancient Greek σκάλλιον (skállion, “small cup”), σκαλίς (skalís, “shovel”). Pokorny considered a parallel formation in Sanskrit कलश (kaláśa-, “(water-)jar, tub, pot, dish”), for Proto-Indo-European *kel-eḱ-, but De Vaan finds this unlikely. Alternatively, borrowed from Ancient Greek κύλιξ (kúlix, “drinking cup”) or an unattested variant thereof, maybe with contamination from κάλυξ (kálux, “shell, hull”), but it is also possible that all were borrowed from related substrate words.
