coincident

Etymology

The adjective is borrowed from French coïncident, from Medieval Latin coincidentem, an accusative singular form of Latin coincidēns (“coinciding”), the present active participle of coincidō (“to coincide”), from co- (variant of con- (prefix denoting a being or bringing together of several objects)) + incidō (“to fall into any condition”) (ultimately from Proto-Indo-European *ḱh₂d- (“to fall”)). The noun is derived from the adjective.
