Forms
īnferī m pl (genitive īnferōrum or īnferum); second declension[1] An inscription spells it eimferīs.[1]
Etymology
It is the masculine plural of īnferus (“lower, below”), used as a noun.[1][2] De Vaan traces ⟨īnferus⟩ to Proto-Italic *enþero- (“lower”) and Proto-Indo-European *n̥dʰero- (“lower”), cognate with Faliscan ifra (“beneath”), Sanskrit अधर (ádhara-, “lower”) and Gothic 𐌿𐌽𐌳𐌰𐍂 (undar, “under”), and perhaps with Gaulish anderon (“of the gods of the underworld”).[3] The ⟨f⟩ inside the word may be a dialect form, as the Faliscan word suggests, or may have arisen because ⟨in-⟩ was felt to be the preposition.[3]
Earliest recorded meaning
De Vaan dates ⟨īnferus⟩ from Plautus,[3] who calls on the “gods and goddesses above and below” in the Cistellaria.[2]
Semantic evolution
It is the inhabitants of the underworld, both the dead and the gods below, as Cicero's “to have gone to the gods above rather than to those below”.[1][2] By metonymy it is the land of the dead, the underworld itself, as Ennius' vast caves of the dead and Apuleius' bars of the underworld.[1]
Church Latin glosses it “those in the underworld, the dead”, and the singular īnferus as the underworld, hell or Sheol;[4] in medieval Latin the plural also means hell.[5]
