Pronunciation

  • /opiˈnjon/, [o.piˈnjõn][1]

Forms

opinión f (plural opiniones)[1] The Calila e Dimna (1251, in a later copy) writes opiñón, and Old Spanish also has openion.[2][3]

Etymology

It is borrowed from Latin opīniō (“opinion, belief; reputation”).[4][5][6][1] The Latin noun is formed from opīnor (“to think, suppose, conjecture”) with the suffix -iō.[7][1] De Vaan rejects or doubts the proposed sources of the verb, among them a link with optō (“to choose”), since the step from “choose” to “believe” is weak.[8]

The same Latin word is Portuguese opinião, Catalan opinió, French opinion and Italian opinione.[1][9] Nascentes calls the Portuguese word semi-learned.[10]

Earliest recorded meaning

The first record in the CDH is in the Fuero de Zorita de los Canes (1218–c. 1250), where a widow is to live on the goods moderately segund opinion de buenos omnes “according to the judgement of good men”.[2] Corominas dates it about 1250, in Alfonso X's Setenario, which has a law on what an opinión is.[4][5][2]

Semantic evolution

Alfonso X's astrological works use the word for each of the views held by the authorities: the Judizios de las estrellas count cinco oppiniones.[2][11] Alonso de Palencia uses it often, and Nebrija records it as Castilian.[4] It was frequent in the Golden Age, when it also meant “fame, reputation” and, in Calderón, “honour”, perhaps first as a euphemism: in El alcalde de Zalamea Pedro Crespo asks Restaurad una opinión que habéis quitado “restore the honour you have taken away”.[4][12] Medieval Latin opinio already meant “repute, fame”.[13]

The Diccionario de Autoridades (1737) defined it as a judgement formed about something where there are reasons for the contrary, and as the fame or concept in which someone is held, with the phrases andar en opiniones and hacer opinión.[14] The noun is far more popular than the verb opinar, which Covarrubias left out; many country people say la piñón.[4] The phrase opinión pública is now its own sense.[6]
