Pronunciation

  • IPA (Ecclesiastical): [ˈliː.bet][1]

Forms

libet (present infinitive libēre, perfect active libuit or libitus est, supine libitum); second conjugation, impersonal, optionally semi-deponent, no future active participle, no gerund[1]

Etymology

It is inherited from Proto-Italic *luf-ē- (“to desire”), inherited from Proto-Indo-European *lubʰ-éh₁- (“to please”), from the root Proto-Indo-European *lewbʰ- (“to love, desire”).[2][1] The older form lubet shows the original /u/, which was unrounded between a velar /l/ and /b/.[2][3] Cognate with Oscan loufir (“or”), Sanskrit लुभ्यति (lubhyati, “desires”), Old Church Slavonic любъ (ljubŭ, “dear”), Gothic 𐌻𐌹𐌿𐍆𐍃 (liufs, “dear”) and English love.[2][4][1] De Vaan compares the sense of Oscan “or” and Latin -libet (“any”) with Old Church Slavonic любо (ljubo, “or”), from “one wants”.[2]

Earliest recorded meaning

De Vaan dates it from Plautus, whose Jupiter changes his shape whenever he likes.[2][4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It was impersonal: it pleases, one feels like, with a dative of the person, libet mihi “I want”, alone, with an infinitive, or with a neuter pronoun, dīc quod libet “say what you please”.[4][6] In the phrase quī libet it meant “any you please”, and it fused into indefinite pronouns such as quīlibet and uterlibet.[4][2] Its perfect was libuit or libitum est.[4][7] From the same verb come libēns “willing”, and libīdō “desire, lust”, whose suffix was influenced by cupīdō.[2]

English libido was borrowed from libīdō in 1892.[8]

Timeline

  • c. 250–184 BC – Plautus uses it.[4][5]
  • 234–149 BC – Cato uses it with an infinitive.[4][5]
