Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

1. aeternō, adv., v. aeternus fin. 3.

2. aeterno, āre, v. a. [aeternus], to perpetuate, to immortalize (rare, perh. extant only in the two foll. exs.): litteris ac laudibus aeternare, Varr. ap. Non. 75, 20: virtutes in aevum, * Hor. C. 4, 14, 5.

aeternus, a, um, adj. [contr. from aeviternus, Varr. L. L. 6, § 11 Müll., from aevum, with the termination -ternus as in sempiternus, hesternus], without beginning or end, eternal (sempiternus denotes what is perpetual, what exists as long as time endures, and keeps even pace with it; aeternus, the eternal, that which is raised above all time, and can be measured only by œons (αἰῶνες, indefinite periods); for Tempus est pars quaedam aeternitatis, Cic. Inv. 1, 27, 39. Thus the sublime thought, without beginning and end, is more vividly suggested by aeternus than by sempiternus, since the former has more direct reference to the long duration of the eternal, which has neither beginning nor end. Sempiternus is rather a mathematical, aeternus a metaphysical, designation of eternity, Doed. Syn. I. p. 3).
