The story of Eternity
Aevum meant a lifetime or an age, and aeternus is 'lasting for an age' contracted — so eternity began as a long span rather than an endless one. The Greek aion behind 'aeon' is the same word. Eternity entered American given-name use recently and appears in the registers in current use.
Meaning
endless time
From the Latin aeternitas, from aeternus, contracted from aeviternus — from aevum, 'age' or 'lifetime'. The same root gives the Greek aion and, through Germanic, the English 'ever' and 'aye'. The etymology is documented.
