116–27 BC, Varro
Ultimate origin
Proto-Indo-European (*pos(ti))

Forms

posteāquam (not comparable)[1] It is also written separately, posteā quam.[2][3]

Etymology

It is formed from posteā (“afterwards”) and quam (“than, as”).[2][1][4] ⟨posteā⟩ is post (“after”) with ea, and de Vaan derives ⟨post⟩ from Proto-Italic *posti (“behind, after”) and Proto-Indo-European *pos(ti) (“after”), cognate with Oscan púst (“after”) and Umbrian post (“after”).[5]

Earliest recorded meaning

Köbler gives Varro as its first author;[4] the Capitoline Fasti record that Quintus Petillius was killed after his colleague had been elected.[2]

Semantic evolution

It is a conjunction of time, after, with the perfect indicative and also the pluperfect.[2] It is also from the time that, ever since, as Cicero's “since I was freed from the great worry of canvassing, I have thought of nothing but the trial”.[2] The TLL notes that some authors, such as Vitruvius and Celsus, use only the joined form.[3]

Church Latin glosses it “after”.[6]
