means A unit of liquid volume equal to four quarts, though the US gallon (about 3.79 liters) is noticeably smaller than the British imperial gallon (about 4.55 liters).
from From Old North French 'galon,' a variant of Old French 'jalon,' meaning a liquid measure, likely tied to a Latin or Late Latin root for a bowl or vessel. The word crossed the Channel with the Normans and settled into English medieval trade — and when the British later standardized the imperial gallon while the young United States kept an older measure, the single word ended up describing two different volumes, one on each shore of the Atlantic.
