Pronunciation

  • IPA (Classical): [ˈliː.bɛ.riː][1]
  • IPA (Ecclesiastical): [ˈliː.be.ri][1]

Forms

līberī m pl (genitive līberōrum); second declension[1] Inscriptions have nominative and dative leibereis.[2] The genitive is usually līberum, but līberōrum is used from Ennius and Plautus on, and the singular is rare.[2]

Etymology

It is the plural of līber “free”, used as a noun.[2][3][1] The OLD notes that the development of the sense “children” is variously explained.[2] De Vaan follows Benveniste, who explains it from legal language, in which the legitimate children of a free couple were called “the free ones”.[3] ⟨līber⟩ goes back to Proto-Italic *leuþero-, from Proto-Indo-European *h₁leudʰ-ero-, originally “belonging to the people”, as in Ancient Greek ἐλεύθερος (eleútheros, “free”).[3] The dative plural Venetic louderobos (“for the children”) shows the same sense.[3]

Earliest recorded meaning

De Vaan dates the sense “children” from Plautus, and Ennius has the genitive līberōrum.[3][2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant sons and daughters, children, always in relation to their parents rather than by age, as in Cicero's līberōs prōcreāre “to beget children”.[2][5] In law it included grandchildren and further descendants, as in Gaius and Ulpian, and Pliny the Younger and Suetonius mention the iūs trium līberōrum “right of three children”.[2]

In British Medieval Latin it meant sons and daughters, children, and in the singular a son, child.[6]
