Forms

perfectiō f (genitive perfectiōnis); third declension[1]

Etymology

It is from perficiō “to complete, perfect” with the suffix -tiō; ⟨perficiō⟩ is from per- and faciō “to make”.[2][1][3] De Vaan traces ⟨faciō⟩ to Proto-Indo-European *dʰeh₁- (“to put”).[4]

Earliest recorded meaning

Köbler's earliest source is Cicero, whom he dates 81–43 BC, and the OLD's first citations are from Cicero.[5][2]

Semantic evolution

It was the bringing of a work to completion, completion, as in Cicero; and the bringing to perfection, the perfected state, perfection, as in Cicero's optimī perfectiō atque absolūtiō.[2][6]

In Ecclesiastical and Medieval Latin it was perfection, the perfect state.[7][8] British Medieval Latin used it for the completion of a process or an artefact.[9] English perfection (early 13th century) came through Old French perfection.[3]
