'aristocrat' originates from Greek, specifically the word 'aristokratēs,' where 'aristos' meant 'best' and 'kratos' meant 'power.'

'aristokratēs' transformed into the French word 'aristocrate,' and eventually became the modern English word 'aristocrat' through Middle English.

Initially, it meant 'rule by the best,' but over time it evolved into its current meaning of 'a member of the nobility.'
