'authority' originates from Latin, specifically the word 'auctoritas,' where 'auctor' meant 'originator' or 'promoter.'

'auctoritas' transformed into the Old French word 'autorité,' and eventually became the modern English word 'authority' through Middle English.

Initially, it meant 'influence or command,' but over time it evolved into its current meaning of 'power or right to give orders.'
