  • IPA (Ecclesiastical): [ˈɛː.vum][1]

Forms

aevum n (genitive aevī); second declension[1]

Etymology

It is inherited from Proto-Italic *aiwom (“period, age”), from Proto-Indo-European *h₂eyu- (“long time, lifetime”).[1][2] The TLL thinks it was first the neuter of an adjective.[3] Cognate with Sanskrit आयुस् (āyus, “life”), Ancient Greek αἰών (aiṓn, “age”), Gothic 𐌰𐌹𐍅𐍃 (aiws, “time, age”) and German ewig (“eternal”).[4][5] The old spelling was ⟨aevom⟩, and Plautus and Lucretius treat it as masculine.[4][5]

Earliest recorded meaning

Köbler gives Ennius first.[2] Köbler dates Ennius 204–169 BC.[2] Plautus has it, as a masculine, in a prayer to Jupiter “through whom we live our life”.[4]

Semantic evolution

It meant time as an endless continuous duration, the whole of past or future time, in aevum or per aevum was “for ever”.[4][5] From this it was time as the cause of change and decay, a very long period, an age, a generation or century, and the lifetime of a person.[4] It also meant life and existence, undying fame, vigour, one's age in years, and old age.[4]

In Christian and medieval Latin it was this present world and eternity,[6] and medieval philosophy used it for aeviternity, the mean between time and eternity.[1] It survives in Italian evo and Spanish evo.[1]

  • c. 250–184 BC – Plautus uses it as a masculine, of life.[4][2]
