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]
