Ultimate origin

Pronunciation

  • Classical: [ˈjuː.ɡɛ.rũː][1]
  • Ecclesiastical: [ˈjuː.d͡ʒe.rum][1]

Forms

iūgerum n (genitive iūgerī); irregular, variously declined, second declension, third declension[1] The genitive singular is usually iūgerī, with iūgeris in Mela; the plural has iūgerum, iūgeribus and also iūgerīs in Cato and Varro.[2][3] An inscription has iugra for iūgera.[2]

Etymology

De Vaan derives it from the PIE neuter s-stem Proto-Indo-European *(H)ieug-os- (“yoked animals, team”), from the root of iungō (“to yoke”): in Latin it came to mean the land a team of oxen could plough in a day.[4] Wiktionary gives Proto-Italic *jougos (“yoked team”) and explains the plural as keeping the old consonant stem.[1] The OLD compares iugum (“yoke”), Ancient Greek ζεῦγος (zeûgos, “team, yoke of beasts”) and Old High German jūhhart (“measure of land”).[2]

Earliest recorded meaning

De Vaan dates the plural iūgera from Cato and the singular from Varro;[4] Köbler gives Varro.[5]

Semantic evolution

It is a measure of land, 240 by 120 Roman feet, about two-thirds of an acre.[2][1] In the plural it is loosely a broad stretch of ground or of farmland, “acres”, as Statius' acres of the Circus, and Mela seems to use it as a measure of length, 240 feet.[2]

Church Latin glosses it “acre”.[6] In medieval Latin it was confused with iugum.[7]

Timeline

  • 234–149 BC – Cato uses the plural.[4][5]
  • 116–27 BC – Varro uses the singular.[4][5]
  • 43/44 AD – Mela of a length of 240 feet.[2][5]
  • c. 45–96 AD – Statius of the acres of the Circus.[2][5]
