Pronunciation

  • IPA (Classical): [ɪm.mɔrˈtaː.lɪs][1]

Forms

immortālis (neuter immortāle, adverb immortāliter); third-declension two-termination adjective[1] Also spelled inmortālis.[2]

Etymology

It is from in- “not” and mortālis “mortal”, from mors “death”.[2][1][3] The Thesaurus compares Ancient Greek ἄμβροτος (ámbrotos, “immortal”) and Sanskrit अमृत (amṛ́ta-, “immortal”).[4] De Vaan traces ⟨morior⟩ “to die” to Proto-Indo-European *mr̥-yé- (“to die”).[5]

Earliest recorded meaning

The OLD's earliest citations are from Plautus.[2] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It meant not subject to death, immortal, as in Plautus and Cicero; imperishable, everlasting, as in Cicero; and of the gods, divine, as in Virgil.[2][7]

In Ecclesiastical and Medieval Latin it was used of God and Christ, of pagan gods and of stars.[8][9] English immortal is recorded in the late 14th century.[3] It survives in Italian immortale and French immortel.[1]
