'convince' originates from Latin, specifically the word 'convincere,' where 'con-' meant 'together' and 'vincere' meant 'to conquer.'

'convincere' transformed into the Old French word 'convaincre,' and eventually became the modern English word 'convince' through Middle English.

Initially, it meant 'to conquer or overcome,' but over time it evolved into its current meaning of 'to persuade or assure someone of something.'
