Pronunciation

  • Classical: [ĩːˈfɛr.nʊs][1]
  • Ecclesiastical: [iɱˈfɛr.nus][1]

Forms

īnfernus (feminine īnferna, neuter īnfernum); first/second-declension adjective[1]

Etymology

It is formed from the stem of īnferus (“lower”) with the suffix -nus, after supernus (“upper”).[2][1] De Vaan derives ⟨īnferus⟩ from Proto-Italic *enþero- (“lower”) and Proto-Indo-European *n̥dʰero- (“lower”), with ⟨f⟩ perhaps a dialect outcome.[3] Cognate with Sanskrit अधर (ádhara-, “lower”) and Gothic 𐌿𐌽𐌳𐌰𐍂 (undar, “under”).[3] The noun is the adjective used alone, with ⟨locus⟩ “place” understood.[4][1]

Earliest recorded meaning

De Vaan and Köbler date it from Pacuvius,[3][5] who sets the gods below against the gods of heaven.[2]

Semantic evolution

It is situated lower down, as Lucretius' lower and upper clouds, in astronomy more southerly, and underground, as Seneca's subterranean valley;[2][6] mare īnfernum is the Tyrrhenian Sea, in Lucan.[2][6] Above all it is of the underworld, infernal, as Livy's superī īnfernīque dī, deathlike, as Apuleius' “Stygian sleep”, and of the gods below.[2][6]

As a noun, masculine from Commodian on and neuter in the Old Latin Bible, īnfernus is the underworld and in Christian Latin hell;[4][1][7] Köbler dates the noun from Ambrose.[5] Church Latin also uses it for the grave and Sheol,[7] and medieval Latin for hell.[8] Through Italian inferno it gave English inferno in 1834.[9]

Timeline

  • 220–130 BC – Pacuvius of the gods below.[2][5]
  • 96–55 BC – Lucretius of the lower clouds.[2][5]
  • 59 BC–17 AD – Livy of the gods above and below.[6][5]
  • c. 340–397 AD – Ambrose uses the noun.[5]
  • 1834 – English inferno, through Italian.[9]
