'sophisticate' originates from Latin, specifically the word 'sophisticatus,' where 'sophisticare' meant 'to tamper with' or 'to adulterate.'

'sophisticatus' transformed into the Old French word 'sophistiquer,' and eventually became the modern English word 'sophisticate' through Middle English.

Initially, it meant 'to adulterate or falsify,' but over time it evolved into its current meaning of 'to make more complex or refined.'
