Forms
efecto m (plural efectos)[1] Old Spanish wrote efeto, and Alonso de Palencia effetto;[2] efecto with ⟨c⟩ appears in 1570, and in the 18th century the Academy noted that the form without ⟨c⟩ had been usual in older texts.[3][2]
Etymology
It is a learned word, borrowed from Latin effectus (“execution, accomplishment; result”).[3][4][5][1] The Latin noun is derived from efficiō (“to bring about, produce”), formed ex- and faciō (“to make, do”).[4][6][1] Corominas lists it among the many learned words of the family of that verb, with afecto and defecto.[3]
The same Latin word gave Portuguese efeito, French effet and Italian effetto.[1][7] The French word is recorded from 1272, at first as Old French aifait.[8]
Earliest recorded meaning
The CDH's first hit in Spanish is a charter of 1293 revoking a sentence, with the phrase con efecto “effectively”; the earlier hits, from 1278, are Latin.[9] Corominas dates efeto to J. de Mena's Laberinto (1444), and the BDELC to 1438.[3][4] In the 14th century the word is common in the sense “result, outcome”, as in the effects that the stars produce (Crónica de 1344).[9]
Semantic evolution
The Diccionario de Autoridades defines the word as what follows from a cause and adds the senses “value, validity” (de ningún valor y efecto) and “end, purpose”.[2] The phrase en efecto in its modern sense “indeed” is already in Quevedo, while Cervantes and others used it to mean “in short, in fact”.[3] The 1884 Academy dictionary adds an article of trade, the spin given to a billiard ball, and in the plural movable goods.[10] Modern uses include commercial paper, the special effects of shows and set terms such as efecto invernadero “greenhouse effect” and efecto secundario “side effect”.[5]
