'magistrate' originates from Latin, specifically the word 'magistratus,' where 'magister' meant 'master' or 'chief.'

'magistratus' transformed into the Old French word 'magistrat,' and eventually became the modern English word 'magistrate' through Middle English.

Initially, it meant 'a master or chief,' but over time it evolved into its current meaning of 'an official entrusted with the administration of the laws.'
