## AI Etymology
Coincidental comes from coincidence + -al, from Medieval Latin coincidere 'to fall together', from co- 'together' + incidere 'to fall upon', from cadere 'to fall'. The historical trail runs through coincidere in Latin and cadere in Latin. Morphologically, coincidental is transparent: it draws on coincidence + -al, from Medieval Latin coincidere 'to fall together', from co- 'together' + incidere 'to fall upon', from cadere 'to fall'. Used as an adjective, coincidental now means "happening by chance rather than by design", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in derived forms such as coincidentally and related forms such as coincide, coincidence, and coincident. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
