Etymology

It is inherited from Middle English opportunite,[2][3] borrowed from Old French opportunite,[3][4] and directly borrowed from Latin opportūnitās (“fitness, convenience, favorable time”),[3][2] from opportūnus (“fit, convenient, favorable”),[3][4] the source of opportune, from the phrase ob portum veniens “coming toward a harbor”, said of the wind,[3] from ob “toward” and portus “harbor”, the source of port.[3]

Earliest recorded meaning

Fitness, aptitude: about 1374, a sense now obsolete;[5] a time or condition favorable for a purpose, “fit, convenient or seasonable time”, is from 1375,[5] the late 14th century.[3]

Semantic evolution

The quality of being opportune, timeliness, is from 1531,[5] and an advantageous site or position from 1555.[5] Johnson (1755) defined it as “fit place; time; convenience; suitableness of circumstances to any end”.[6] Equality of opportunity is from 1891.[5] Opportunity cost in economics is attested from 1911,[3][5] and the saying opportunity knocks but once from 1898.[3]
