Etymology Origin:
The word coincidental traces back to Latin roots. The prefix co- (variant of com-) signifies "together," while cidere (from cadere) means "to fall" or "to happen." Combined, they form coincidere, meaning "to fall together" or "to occur simultaneously." Over time, the term evolved in English to describe events that happen by chance or without planned connection, retaining its core idea of "falling together."
