'overthrow' originates from Old English, specifically the word 'oferþrowian', where 'ofer-' meant 'over' and 'þrowian' meant 'to throw'.

'oferþrowian' transformed into the Middle English word 'overthrowen', and eventually became the modern English word 'overthrow'.

Initially, it meant 'to throw over or overturn', but over time it evolved into its current meaning of 'to remove from power'.
