coincide (v.)

1705, "be identical in substance or nature," but from 1640s as a verb in English in Latin form, "occupy the same space, agree in position," from Medieval Latin coincidere (used in astrology), literally "to fall upon together," from Latin com "with, together" (see com-) + incidere "to fall upon" (from in- "upon" + combining form of cadere "to fall," from PIE root *kad- "to fall"). From 1809 as "occur at the same time." Related: Coincided; coinciding.
