Pronunciation

  • /opoɾˈtuno/, [o.poɾˈt̪u.no][1]

Forms

oportuno (feminine oportuna, masculine plural oportunos, feminine plural oportunas)[1]

Etymology

It is borrowed from Latin opportūnus (“well placed; convenient, opportune”), a learned word that Corominas first records in Juan de Mena, about 1440.[2][3][4][1] He explains the Latin adjective as properly a sailors' term for the wind that carries a ship into harbour.[2][3] The OLD analyses it as probably ob- (“towards”) with portus (“harbour”) and a suffix -ūnus, notes that Festus already called it a nautical word, and compares importūnus.[5] Gómez de Silva gives the same analysis, with the implied original sense “(wind) blowing towards the harbour”.[6]

Spanish puerto continues the same Latin noun.[2][7] The Latin adjective was also borrowed as Portuguese oportuno, Catalan oportú, French opportun and Italian opportuno.[1][8][9][10]

Earliest recorded meaning

The Old Spanish Textual Archive has the word first in a manuscript of Juan Fernández de Heredia's Crónica de los conqueridores (1376–1396).[11] Corominas's first record is Juan de Mena, about 1440, in the sense “coming at the right time, fitting”.[2][3] Nebrija's dictionary glosses it cosa con sazón “a thing in its season”.[12][2]

Semantic evolution

Autoridades defined it as something done or happening at the right time, when it was convenient, and quoted a sea “less opportune for navigation” and the silent fields as an instrument mui oportúno, y acomodado para la contemplación “very fitting and suited to contemplation”.[13] Domínguez added the use for a person who always has a witty or apt remark at hand,[14] and the Academy now gives “quick and witty in conversation” as its second sense.[4] Moliner notes that in future and conditional sentences it expresses advisability or need.[15]

The noun oportunidad is recorded from 1438, in the Corbacho.[2][3] Corominas remarks that in Latin America it is overused at the expense of ocasión, perhaps under English influence.[2] The word reached the Americas early: a Mexico City text of 1583 praises the captain's eloquente y oportuna habla “eloquent and timely speech”.[16]
