'impersonator' originates from the Latin word 'personare,' where 'per-' meant 'through' and 'sonare' meant 'to sound.'

'personare' transformed into the French word 'personner,' and eventually became the modern English word 'impersonate,' leading to 'impersonator.'

Initially, it meant 'to sound through,' but over time it evolved into its current meaning of 'to pretend to be someone else.'
