'oppressor' originates from Latin, specifically the word 'oppressor,' where 'opprimere' meant 'to press against or crush.'

'oppressor' changed from the Old French word 'opresseur' and eventually became the modern English word 'oppressor'.

Initially, it meant 'one who presses against or crushes,' but over time it evolved into its current meaning of 'one who exercises harsh control or authority over others.'
