Forms

perpetuitās f (genitive perpetuitātis); third declension[1] The spelling perpetuetas appears on a coin of 378–383, and coins abbreviate the word.[2]

Etymology

It is from Latin perpetuus (“continuous, permanent”) + -tās.[3][1][2] De Vaan lists perpetuus, like perpes (“continuous”), among the words formed from petō (“to make for, seek”).[4]

Earliest recorded meaning

Köbler records it first in Cicero,[5] who speaks of the uninterrupted continuance of someone's goodwill and of an unbroken run of words in a speech.[3][6]

Semantic evolution

It is the quality of being unbroken: in space, an unbroken stretch, as in Vitruvius' opācae perpetuitātēs of tracts of land;[3][6] in time, uninterrupted duration;[3] and in speech, its connected flow.[3][6] Cicero says that philosophers should be judged by their consistency, not by single sayings, and uses ad perpetuitātem, “for ever”.[6] In medieval charters it stands for the lasting force of a grant, and in the Church for a benefice held for life; philosophical writers used it of the soul's perpetuity.[7] Ecclesiastical Latin also used it for eternity.[8] English has perpetuity from the late 14th century, from Old French perpetuité and directly from Latin.[9]
