History and Etymology for acre

Note: This Indo-European noun is traditionally linked to the verbal base *h2eǵ- "drive (cattle, etc.)" (see agent, on the assumption that *h2eǵ-ros originally meant "pasture," "fallow land," onto which the cattle were driven, and later developed other senses, as "cultivated field."
