occasion

n. a particular time or instance of an event

The word "occasion" originates from Latin occasio (a falling, opportunity), derived from oc- (variant of ob-, meaning "toward") + cadere (to fall). The idea is of an event "falling toward" or presenting itself as an opportunity. Over time, it evolved in Old French as occasion before entering Middle English, retaining its core sense of a timely event or circumstance.
