ager

Etymology and origin of the Latin word ager

Pronunciation

  • IPA (Classical): [ˈa.ɡɛr][1]
  • IPA (Ecclesiastical): [ˈaː.d͡ʒer][1]

Forms

ager m (genitive agrī); second declension[1]

Etymology

It is inherited from Proto-Italic *agro- (“field”), inherited from Proto-Indo-European *h₂éǵros (“uncultivated field, pasture”), a derivative of *h₂eǵ- (“to drive, lead”), the root of agō.[2][1] Varro already derived the word from agere.[3][4]

Cognate with Umbrian ager (“field”), Sanskrit अज्र (ájra-, “plain”), Ancient Greek ἀγρός (agrós, “field”), Gothic 𐌰𐌺𐍂𐍃 (akrs) and Old English æcer, the source of English acre.[2][1]

Earliest recorded meaning

It is found from Plautus onwards.[2][5] In the Amphitruo Plautus uses it of the territory of the Teleboans, which the Argives promise to leave.[6]

Semantic evolution

From the start it meant both a territory, as in ager Romanus or ager Tusculanus, and a privately owned piece of land, an estate or farm.[6][4] Land as property gave the legal terms ager publicus and ager privatus, and land as farmed gave agri cultura “agriculture”.[6] It also meant soil of a particular quality, and the countryside as opposed to the town.[6] In inscriptions in agrum meant “in depth”, as of the measurements of a tomb plot.[6]

In medieval Latin it was also a land measure and, in parts of France, a subdivision of a county.[7] Its Romance descendants, such as Romanian agru and Italian agro, continue the senses “field” and “countryside”.[8]

  • 234–149 BC – Cato speaks of the loss of a man's land.[6][5]
  • 116–27 BC – Varro names five kinds of ager recognised by the augurs.[6][5]
  • 81–43 BC – Cicero writes of the cultivation of fields.[9][5]
  • Middle Ages – It is a land measure and a district of a county.[7]
