Pronunciation

  • Classical: [ˈseː.kʊ.boː][1]
  • Ecclesiastical: [ˈsɛː.ku.bo][1]

Forms

sēcubō (present infinitive sēcubāre, perfect active sēcubuī, supine sēcubitum); first conjugation, no passive[1]

Etymology

It is from Latin sē- (“apart”) + cubō (“to lie down”).[2][1] De Vaan explains the prefix as the old ablative ⟨sēd⟩, which as a preposition meant “without, away”.[3] The verb cubō goes back to Proto-Italic *kubā̆je/o- (“be lying”); de Vaan finds a PIE origin of its root uncertain, since it has a /b/ and is found only in Italic and Celtic.[3] Cognate with Faliscan cupat (“lies down”) and Middle Welsh kyscu (“to sleep”).[3]

Earliest recorded meaning

Its first use is in Catullus,[4][5][6] who speaks of sleeping away from someone's breasts, a tuis secubare papillis.[6]

Semantic evolution

It means to sleep apart from one's spouse or lover, or to sleep alone,[2][4] and Lewis and Short note that Cicero never uses it.[4] It is said of a man in Catullus, Livy, Quintilian and Suetonius, and of a woman in Tibullus, whose chaste bed is puro secubuisse toro, and in Ovid.[4][6] Propertius and Apuleius use it more generally of living alone or in seclusion,[5] and Lewis and Short quote miles depositis annosus secubat armis, “the aged soldier lives apart, his arms laid down”.[4] In Apuleius it is also said of someone who reclines apart from the other guests at a dinner.[2][6] In Ecclesiastical Latin it means to live alone.[7]
