Pronunciation
- /peɾˌfeɡtaˈmente/, [peɾˌfeɣ̞.t̪aˈmẽn̪.t̪e][1]
Etymology
It is formed from Spanish perfecto + -mente.[1][2][3] The adjective is from Latin perfectus, the past participle of perficiō (“to complete, perfect”), itself from faciō (“to do, make”); it is recorded since Berceo, often in the spelling ⟨perfeto⟩ to the 17th century.[4][5][6]
Earliest recorded meaning
The CDH's first hit is in the Calila e Dimna (1251, in a copy of the late 14th or early 15th century): el que se trabajara de demandar el saber perfetamente “he who strives to seek knowledge perfectly”.[7] The first hit without a later copy is in the Spanish version of the Council of Coyanza (before 1300), where the Trinity is signified perfetamientre by the host, the wine and the water.[7]
Semantic evolution
Nebrija's Latin–Spanish dictionary of 1492 already glosses Latin exacte with perfecta mente, written as two words.[6] The Diccionario de Autoridades defines the adverb as “completely, without fault, with perfection, polish or care”, and the Academy kept that definition through the 19th century.[8][9] Domínguez (1846) notes that it is often used as an interjection meaning “very well, just as one could wish”.[10] The Academy's 2001 edition records this answer of assent as a sense of its own.[11]
Today the adverb also serves as an intensifier, “fully, very”, before adjectives and verbs (sabe perfectamente “he knows full well”).[12][13] Ramos y Duarte recorded the use before malo or falso (“completely bad, completely false”) in Tamaulipas.[14]
