Pronunciation

  • IPA (Classical): [nɔkˈtʊr.nʊs][1]
  • IPA (Ecclesiastical): [nokˈtur.nus][1]

Forms

nocturnus (feminine nocturna, neuter nocturnum); first/second-declension adjective[1]

Etymology

It is formed from Latin nox (“night”) + -urnus, on the model of diurnus (“daily”).[2][1][3][4] De Vaan cites Pinault's view that it, like noctū (“by night”), rests on an old locative ⟨*nokʷt-eu⟩.[4] nox goes back to Proto-Italic *nok(w)-t- and Proto-Indo-European *nókʷts (“night”).[4][1]

Earliest recorded meaning

De Vaan dates it from Naevius,[4] who calls robbers nocturnōs … praemiātōrēs, “night-time bounty hunters”.[2] Köbler also records it in Plautus.[5]

Semantic evolution

Nocturnus is “of the night” (Cicero: hōrīs nocturnīs), “used at night” (Horace: a night-garment), and of events “happening at night” (Cicero: nocturnal sacrifices).[2][3][1] The triumvirī nocturnī were magistrates who watched over the safety of Rome by night.[2] Of persons and animals it is “active by night”, so fūr nocturnus, “a burglar”, and of the owl nocturna strīx (Horace); as a noun Nocturnus is the god of night in Plautus.[2] Poets use it adverbially, “by night” (Virgil: he steered the ship on the waters at night).[2]

In medieval Latin nocturnī and nocturna are the night office, a service held at night.[6] English nocturne comes from it through French in 1851.[7]
