Where this word comes from
Learned borrowing from Latin aeviternus (“eternal, perpetual”) + English -ity (suffix forming nouns, especially abstract nouns), probably modelled after eternity. Aeviternus is derived from aevum (“infinite time; eternity, timelessness; undefined long period of time, age, era; generation, lifespan, lifetime; temporal mode of existence between time and eternity”) (ultimately from Proto-Indo-European *h₂ey- (“age; eternity; life, vital force”)) + -rnus (suffix forming adjectives). Doublet of aevum and aye.
