Forms

perfeito (feminine perfeita, masculine plural perfeitos, feminine plural perfeitas)[1] Houaiss records perfeito, perfecto and perffeyta in the 14th century and perfeta in the 15th;[2][3] Cunha has perffeito in the 14th.[2][3]

Etymology

It is inherited from Latin perfectus (“finished, complete”), the past participle of perficiō (“to finish, accomplish”).[2][3][1] The Latin /kt/ became /jt/, as in feito, so García de Diego counts the Portuguese and Galician word among the popular outcomes of the Latin one, while Spanish perfecto is a learned borrowing in Spanish.[4][5] The 14th-century spelling Old Galician-Portuguese perfecto shows the Latin form beside the popular one.[2] Morais and Vieira still treat the word as the irregular past participle of perfazer.[6][7] Nascentes observes that the sense improved: from “made to the end, finished” to “without a fault”.[8]

The same Latin word is Italian perfetto, French parfait, and Occitan perfièch.[9][1]

The Latin verb is formed from per-, a completive prefix, and faciō (“to do, make”).[10]

Semantic evolution

Cardoso in 1569 renders the word by Latin exactus and absolutus, and Bluteau defines it as having all the qualities that nature or art require.[11][12] Morais in 1789 lists “finished”, “well finished”, “having all the parts nature gives to its kind”, “without moral fault” and the grammatical tense that denotes a finished action.[6] The intensifying use with a noun of blame (um perfeito parvo) is recorded by the original Caldas Aulete.[13] The DLP also records perfeito! as an exclamation of approval.[14]

Timeline

  • 1755 – Folqman gives não há gosto perfeito “there is no pleasure without alloy”.[15]
  • 1789 – Morais lists the grammatical sense of the tense of a finished action.[6]
