aevitas

Doublet of aetās, which also derives from Proto-Italic *aiwotāts. De Vaan suggests that this term may have restored the initial aevi- on the basis of aevum. Sihler, however, merely considers it to be the intermediary stage between aetās and Proto-Italic *aiwotāts. By surface analysis, aevum +‎ -tās.
