Word History

Etymology

Middle English, borrowed from Anglo-French & Latin; Anglo-French opportun, borrowed from Latin opportūnus "favoring one's needs, serviceable, convenient," probably originally, "blowing in the direction of a harbor (of a wind)," from ob- ob- + portu-, stem of portus "harbor, port entry 1" + -nus, adjective suffix (vowel length perhaps after the ablative portū)

Note: The name of a god of harbors, Portūnus, appears to be a secondary formation by analogy with Neptūnus "Neptune."

First Known Use

15th century, in the meaning defined at sense 1

opportunely adverb

Etymology

Middle English opportune "opportune, suitable, fit," from early French opportun (same meaning), from Latin opportunus "fit, suitable, convenient," from ob- "toward" and portus "harbor"

Word Origin

The Latin adjective opportunus was used to mean "fit, suitable, or convenient." It was formed from the prefix ob-, meaning "toward," and portus, meaning "harbor." The original meaning was probably "blowing in the direction of a harbor (of a wind)," and hence "favoring one's needs, convenient." The French took the word as opportun with the same basic meaning, and the word came into English as opportune in the 15th century. Nowadays it is often applied to a suitable or favorable time for something, or to something that occurs or is done at just the right time.
