Pronunciation

  • IPA (Classical): [liːˈbɛr.tʊs][1]
  • IPA (Ecclesiastical): [liˈbɛr.tus][1]

Forms

lībertus m (genitive lībertī, feminine līberta); second declension[1]

Etymology

It is from līber “free” with the suffix -tus.[2][1] Wiktionary traces it to Proto-Italic ⟨*louðertos⟩, as in Faliscan ⟨loferta⟩ “freedwoman”, from PIE ⟨*h₁lewdʰ-er-tos⟩.[1] Isidore explains it as ⟨quasi līberātus⟩ “as if freed”.[3]

Earliest recorded meaning

Köbler's first source is the Law of the Twelve Tables, about 450 BC.[4]

Semantic evolution

It meant a freedman, with reference to the master who freed him, his patron.[2] Döderlein explains that lībertus is the freedman in relation to his former master, opposed to servus, while lībertīnus refers to his rank, opposed to cīvis and ingenuus.[5] Isidore adds that the sons of freedmen were called lībertīnī by the ancients.[3]

It was borrowed into Italian liberto.[1]

Timeline

  • c. 450 BC – The Twelve Tables use it.[4]
  • 81–43 BC – Cicero uses it of a freedman made heir.[5][4]
