The History of the Word

The word gallon, referring to the English unit of measurement that contains four quarts, originated in the late thirteenth century. It is derived from the Old Northern French word galon, which corresponds to the Old French word jalon, a liquid measure that is roughly equivalent to the modern gallon. The Old French word was derived from the Medieval Latin word jale or the Latin diminutive form galleta, which means “bucket, pail, or measure of wine.” It is a word of unknown origin past Latin, but may also have derived from the Gaulish word galla, which means “vessel.”
