Pronunciation

  • Classical: [nɔk.tʊrˈnaː.lɪs][1]
  • Ecclesiastical: [nok.turˈnaː.lis][1]

Forms

nocturnālis (neuter nocturnāle); third-declension two-termination adjective[1]

Etymology

It is formed from Latin nocturnus + -ālis,[1] the base being nocturnus (“of the night”), from nox (“night”).[2][3]

Earliest recorded meaning

It is post-classical:[4] the first author to use it is Sidonius Apollinaris, of a hood worn at night (cucullus nocturnalis).[4][2]

Semantic evolution

Alcimus Avitus uses it of a dwelling at night.[4][5] In Church Latin it meant “of the night”, above all of the night office (nocturnale officium).[6][7] As a noun, masculine nocturnalis or neuter nocturnāle named the liturgical book for the night services, and the plural nocturnālēs or nocturnālia meant night shoes.[7][2] British sources also use it for things that happen or appear at night.[8]

English took it over in the late 15th century, through French or directly, as nocturnal.[3]
