Pronunciation

  • IPA (Classical): [ɔp.pɔrˈtuː.nɪ.taːs][1]
  • IPA (Ecclesiastical): [op.porˈtuː.ni.tas][1]

Forms

opportūnitās f (genitive opportūnitātis); third declension[1]

Etymology

It is from Latin opportunus (“fit, convenient”) + -tās.[2][1][3] Etymonline derives opportūnus from the phrase ob portum veniēns (“coming toward a port”), said of the wind, from ob and portus “harbour”.[4] A variant spelling is oportūnitās.[2][5]

Earliest recorded meaning

Plautus, in the Epidicus, says “I see you both come at the best moment”.[2] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It was the quality of serving one's needs, advantage, convenience, and especially a favourable position, as of a province or of places for camps in Caesar.[2][5] It was also a favouring circumstance, and Cicero says friendship has so many advantages he can hardly tell them.[2] It meant the right timing of an event, then an opportunity or chance, as in Sallust, and the ability to seize chances, as in Caesar.[2] Döderlein distinguishes occāsiō, a chance to undertake something in general, from opportūnitās, a chance with special convenience.[7]

In medieval Latin it kept the sense of convenience or suitability.[8] English opportunity is recorded in the late 14th century as a fit time.[4]

Timeline

  • c. 250–184 BC – Plautus uses it of good timing.[2][6]
  • 81–43 BC – Cicero speaks of the advantages of friendship.[2][6]
  • 86–34 BC – Sallust uses it of opportunities.[2][6]
  • late 14th century – English opportunity is recorded.[4]
