Etymology

It is Middle English occasioun, borrowed from Old French ocasion (“cause, reason, opportunity”) or directly from Latin occāsiō (“opportunity, fit time”),[2][3][4] in Late Latin “cause”,[2][4] from occāsus, the past participle of occidere (“to fall down, go down, set”),[2][3] from ob- (“down, away”) and cadere (“to fall”),[2][3][5] from Proto-Indo-European *kad- (“to fall”).[2] The idea is a falling together, or juncture, of circumstances.[2][6] It is related to cadence and accident.[3][7]

Earliest recorded meaning

A favourable juncture or opportunity, and a reason or cause: 1382, in the Wycliffe Bible.[6][3]

Semantic evolution

A pretext or excuse is from 1388 and obsolete.[6] The time at which something happens is from the 1560s, 1568 in Barnhart,[2][3] and a juncture calling for action, a particular case, from the 16th century.[4] Opportunity personified as a woman bald behind, as in take occasion by the forelock, is from about 1592.[6] The verb, to cause, is from the mid-15th century, about 1445 in Barnhart.[2][3] Occasional first meant “casual” in the 16th century,[4] and happening now and then later.[3]
