Forms
opinar (first-person singular present opino, first-person singular preterite opiné, past participle opinado)[1]
Etymology
It is borrowed from Latin opīnor (“to think, believe, suppose”), a deponent verb.[2][3][1][4] Early Latin also had an active opīnō, in Plautus and Ennius, and the Academy's 1884 edition gives that active infinitive as the source.[5][6] Corominas treats the verb under opinión.[3]
The Latin verb is formed on an adjective seen in inopīnus (“unexpected”), whose origin is unclear.[1] It is traditionally connected with optō (“to choose, wish”) and Proto-Indo-European *op- (“to choose”), as Gómez de Silva does, but Schrijver finds the link between “choose” and “believe” weak.[7][1][8] Vine points out that a Praenestine inscription spells it opeinor, with a diphthong that makes the analysis harder.[7][1]
The same learned verb is Portuguese opinar, Catalan opinar, French opiner and Italian opinare.[1] In Portuguese it is recorded from the 17th century.[9]
Earliest recorded meaning
The earliest CDH hit is the participle in Juan Fernández de Heredia's translation of Eutropius (1377–1399): espauorido por sobtosa et no opinada sobreuienta, “terrified by a sudden and unexpected attack”.[10] Enrique de Villena's Arte cisoria (1423) uses the gerund opinando, “supposing”.[10] Corominas dates the verb to 1495, Nebrija's Vocabulario, and DICCA-XV to 1417.[3][4]
Semantic evolution
Nebrija's Latin dictionary of 1492 glosses opinor as “to think with opinion”, and his Spanish–Latin Vocabulario has opinar for it.[4] In the 15th century Hernando del Pulgar also used it for “to deem”: Muchos de los que opinamos de noble sangre veemos pobres, “many of those whom we deem of noble blood we see poor”.[10] The Diccionario de Autoridades made it intransitive, “to reason or judge with probability about a matter”.[11] A Guatemalan text of 1716 has the passive fue generalmente opinado que …, “it was generally thought that …”.[12] The DLE now gives transitive and intransitive senses, to hold and to express an opinion.[2] Moliner notes that a speaker gives an opinion with this very verb in the first person: opino que ….[13]
