Pronunciation

  • Classical: [lɪ.biː.dɪˈnoː.sʊs][1]
  • Ecclesiastical: [li.bi.diˈnɔː.s̬us][1]

Forms

libīdinōsus (feminine libīdinōsa, neuter libīdinōsum, comparative libīdinōsior, superlative libīdinōsissimus, adverb libīdinōsē); first/second-declension adjective[1] The older spelling lubīdinōsus is also found.[2][3]

Etymology

It is from Latin libīdō (“desire, lust”) + -ōsus.[2][1][4] The noun is made from libet (“it pleases”), which de Vaan traces to Proto-Italic *luf-ē- (“to desire”) and Proto-Indo-European *lubʰ-eh₁- (“to please”).[5] Cognate with Oscan loufir (“or”), Gothic 𐌻𐌹𐌿𐍆𐍃 (liufs, “dear”) and Old High German liob (“dear, sweet”).[5] Varro derived libīdō from ⟨lubendo⟩, and Isidore explains the libidinous man as one who does what he pleases.[4]

Earliest recorded meaning

Köbler dates it from Cicero,[6] who calls Verres a self-willed and cruel tyrant.[2]

Semantic evolution

It means self-willed, arbitrary or capricious, as in Cicero and Nepos, and of prices extravagant, as in Columella.[2] More often it is lustful, licentious or libidinous, as Cicero's “a most shameful, most lustful and most worthless man”, and of actions and writings wanton.[2][3] Wiktionary also gives passionate and yearning for something.[1] English libidinous (mid-15th century) came through Old French or directly from Latin.[7]
