English - Etymology
From Old Northern French galun, galon (“liquid measure”) (compare Old French jalon), from Late Latin galum, galus (“measure of wine”), from Vulgar Latin *galla (“vessel”), possibly from Gaulish, ultimately from Proto-Indo-European *kel-, *kol- (“goblet”). Cognate with Ancient Greek κύλιξ (kúliks, “cup”), Sanskrit कलश (kalaśa, “jar, pitcher; measure of liquid”). Related to Old French gille (“wine measure”) (from Medieval Latin gillo (“earthenware jar”)), Old French jale (“bowl”), Old French jaloie (“measure of capacity”).
