Word History

Etymology

Middle English aker, acre, going back to Old English æcer, going back to Germanic *akraz (whence also, with k geminate in West Germanic, Old Saxon akkar "field," Old High German ackar, Old Norse akr "arable land," Gothic akrs "field"), going back to Indo-European *h2eǵros, whence also Latin ager, "piece of land, field," Greek agrós, Sanskrit ájrah

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." The semantic plausibility of such a derivation has recently been questioned, however.
