Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Indo-European (*pos(ti))

Forms

posteritās f (genitive posteritātis); third declension[1] A manuscript of Servius spells it postteritās.[2]

Etymology

It is formed from posterus (“coming after”) with the suffix -tās.[3][2][1] De Vaan explains ⟨posterus⟩ as the old comparative of post (“after”), from Proto-Italic *post-ero- (“later”), and ⟨post⟩ from Proto-Indo-European *pos(ti) (“after”).[4] Cognate with Oscan pústreí (“later”) and Umbrian postra (“later”).[4] Servius explained it as ⟨postera aetās⟩, “the later age”, and Isidore of Seville also discusses it.[2]

Earliest recorded meaning

Köbler gives Cicero as its first author,[5] who asks Verres whether he should have considered one year and neglected the interest of the state for the future.[3]

Semantic evolution

It is future time, the time to come, as in the Verrines, and future generations, posterity, as Cicero's “not even the posterity of all ages will forget this” and his hope that the friendship of Scipio and Laelius will be known to posterity.[3][6] It is also descendants, offspring, as in the declamations ascribed to Quintilian, and posthumous fame, as Cicero's “no one of us faces dangers for the state without the hope of posterity”.[3][1]

Church Latin glosses it “progeny, future, offspring”,[7] and in medieval Latin it is descent and offspring.[8]
