'perpetrator' originates from Latin, specifically the word 'perpetrator,' where 'per-' meant 'through' and 'patrare' meant 'to perform.'

'perpetrator' changed from the Latin word 'perpetrator' and eventually became the modern English word 'perpetrator.'

Initially, it meant 'to perform or execute,' but over time it evolved into its current meaning of 'a person who carries out a harmful act.'
