gallon

gallon: [13] English acquired gallon from Old Northern French galon. This was a descendant of medieval Latin gallēta, a word for a ‘jug’ which was also used as a unit of measurement for wine. It may have been of Celtic origin. An early modern English dialect form of gallon was gawn, which added to tree produced gantry [16], originally a ‘wooden stand for barrels’.
