The word acre
comes from the early English word acer
. This word simply meant "a ploughed field." When the word "acre" was first used for an amount of land, it meant the amount of land that a pair of oxen could plough in one day. A three-acre field might differ in size from region to region. Later a law was passed in England that made an acre a standard unit of area.
