Pronunciation

  • Classical: [ˈkʊ.bɪ.toː][1]
  • Ecclesiastical: [ˈkuː.bi.to][1]

Forms

cubitō (present infinitive cubitāre, perfect active cubitāvī, supine cubitātum); first conjugation[1]

Etymology

It is from Latin cubō (“to lie down”) + -itō, a frequentative.[2][3] De Vaan lists it from Plautus on among the words of the family of -cumbō, and reconstructs the base as Proto-Italic *kubā̆je/o- (“to be lying”).[4] Because of the /b/ and because the root is found only in Italic and Celtic, its Indo-European origin is uncertain.[4]

Cognate with Faliscan cupat and Paelignian incubat, both “lies”, and with Middle Welsh kyscu (“to sleep”).[4]

Earliest recorded meaning

De Vaan finds it from Plautus on.[4] In the Curculio a character remarks anus hīc solet cubitāre, “an old woman usually sleeps here”.[3][5]

Semantic evolution

It means to lie down or recline habitually, especially to sleep.[2][3] With cum it was used of sleeping with someone, in the sexual sense, in Plautus and later in Quintilian.[2][3] Cicero uses it of a boy who slept with his older sister.[5] Columella says it of peacocks that roost on the ground, and Tacitus of reclining at someone's feet.[3][5] In Ammianus it is said of soldiers encamped before a wall.[5]
