'coincidence' originates from Medieval Latin, specifically the word 'coincidentia,' where 'co-' meant 'together' and 'incidere' meant 'to fall upon.'

'coincidentia' transformed into the French word 'coïncidence,' and eventually became the modern English word 'coincidence' through Middle English.

Initially, it meant 'the act of falling together,' but over time it evolved into its current meaning of 'a remarkable concurrence of events.'
