Pronunciation
- /impeɾˈfeɡto/, [ĩm.peɾˈfeɣ̞.t̪o][1]
Forms
imperfecto (feminine imperfecta, masculine plural imperfectos, feminine plural imperfectas)[1]
Etymology
It is borrowed from Latin imperfectus (“unfinished, incomplete”), a learned word.[2][3][1] The Latin adjective is formed in- (“not”) and perfectus (“finished, perfect”), the past participle of perficiō (“to complete”).[4][3][5] By surface analysis the Spanish word is perfecto with the negative prefix in-.[1]
The same Latin word is Portuguese imperfeito, Catalan imperfecte, French imparfait and Italian imperfetto.[6][7][8][5] Spanish also wrote it ⟨imperfeto⟩, as it wrote ⟨perfeto⟩, in the 16th and 17th centuries, the spelling Cervantes used.[3][9][10]
Earliest recorded meaning
Corominas dates the word to 1490, in Alfonso de Palencia's dictionary, with a second record in Fray Luis de Granada in 1580.[3][11] The Old Spanish Textual Archive has it in a 15th-century manuscript of Martín Pérez's Diccionario eclesiástico, which it files under 1401.[12]
Semantic evolution
Both senses of the Latin adjective, “not perfect” and “begun but not finished”, are in the Diccionario de Autoridades, which quotes Fray Luis de Granada on the imperfect goods of this life and Cervantes on a work left unfinished (quedasse imperfecta la obra); it also has the grammatical term, for a tense that is not exactly present, past or future but close to one of them.[13] A Mexican grammar of 1571 already speaks of the pretérito imperfecto.[10] Salvá defined that tense in 1846 as one whose past action coexisted with another, and Domínguez listed imperfecto as a noun for it.[14][15] In 1917 Alemany added botanical and musical uses: an unfertilised seed, a chord lacking some of its notes.[16] In Cuba the word is used colloquially of a rude or tiresome person.[17]
