Pronunciation

Forms

æcer m (genitive singular æcres, nominative plural æcras)[1]

Etymology

It is inherited from Proto-West Germanic *akr, from Proto-Germanic *akraz (“field”).[1][2] The Proto-Germanic noun is found in all the old Germanic languages: Gothic 𐌰𐌺𐍂𐍃 (akrs), Old Norse akr, Old Frisian ekker, Old Saxon akkar and Old High German ackar.[2][3][4]

Outside Germanic it matches Latin ager (“field”), Ancient Greek ἀγρός (agrós, “field”) and Sanskrit अज्र (ájra, “plain, field”), which point to Proto-Indo-European *h₂éǵros (“field”).[1][3] Kroonen analyses it as *h₂eǵ-ro-, and Orel and Köbler take it as a derivative of the verbal root Proto-Indo-European *h₂eǵ- (“to drive”), the field being first the land over which cattle were driven.[2][3][4]

Earliest recorded meaning

The earliest dated record is in the English bounds of a charter of 869 in which King Burgred of Mercia and Queen Æthelswith grant land to Wulflaf: æt peadan beorge seondon sex æcras innlondes ægþer ge medlondes ge eyrð londes “at ⟨peadan beorge⟩ there are six acres of inland, both of meadow and of ploughland”.[5][6] The single sheet is dated to the ninth century, although the British Museum facsimiles thought it possibly of the tenth.[5] In the Pastoral Care of 890×897 the word is “field”, in Isaiah's woe on those who spannað ðone æcer to ðæm oðrum oð ðæs landes mearce “join one field to the next as far as the land's boundary”.[7][6]

Semantic evolution

Bosworth and Toller set out two senses: a field, land that is sown, glossing Latin “ager” and “seges”, and a fixed measure of land, the area a team of oxen could plough in a day, rendering “jugerum”.[8] Toller's Supplement adds the crop raised on the land, as in Gregory's Dialogues, and estimates the acre as four rods broad and forty long.[9] In the laws it is opposed to the house, then a strip of sown land, and elsewhere a unit of area.[10] The charters count land in acres, as in twelf æceras mǣde “twelve acres of meadow”.[9]

The word lived on as Middle English aker, first recorded in the early fourteenth century, now acre.[11][12]
