chalice

From Middle English chalis, from Anglo-Norman, from Old French chalice, collateral form of calice, borrowed from Latin calix, calicem (“cup”), of uncertain etymology. In view of Umbrian skalçeta (“sacrifical vessel”), perhaps from a Proto-Italic *(s)kalik-, from Proto-Indo-European *(s)kel-. 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) or an unattested variant thereof, maybe with contamination from κάλυξ (kálux, “shell, calyx”), but it is also possible that all were borrowed from related substrate words. Possible doublet of calyx and kelch. Compare Sumerian 𒃲(GAL).
