Pronunciation

  • Classical: [ĩː.fɛrˈnaː.lɪs][1]
  • Ecclesiastical: [iɱ.ferˈnaː.lis][1]

Forms

īnfernālis (neuter īnfernāle); third-declension two-termination adjective[1]

Etymology

It is from Latin īnfernus (“lower; of the underworld”) + -ālis.[2][3][4][5] The TLL compares adjectives such as ⟨aeternālis⟩ beside ⟨aeternus⟩.[2] Wiktionary takes it instead from the neuter plural noun īnferna (“the underworld, hell”).[1]

Earliest recorded meaning

Its first datable author is Prudentius, who calls Pluto the Iuppiter īnfernālis in his poem against Symmachus.[2][6][3][7] The epitome of Festus has diī īnfernālēs, the gods below, as opposed to those above,[2] and curse tablets address a power “who holds the infernal parts”.[2]

Semantic evolution

Christian writers made it the adjective of hell: Augustine speaks of infernal angels, sermons among his works and those of Caesarius of Arles of infernal flames, and Gregory of Tours of infernal death and torments.[2] From this it came to mean dire or damnable, as in “infernal works”.[2]

Medieval Latin kept the sense “of hell”, and the neuter plural īnfernālia meant hell itself.[8][9] Bede speaks of a man to be handed over to infernal torments.[10] It was also used of what is dark and gloomy, as a prison, of what brings ruin, as a wolf's open jaws in Alcuin, and of what is damnable, as flattery.[9] English infernal came from it through Old French in the late 14th century.[5]
