'executor' originates from Latin, specifically the word 'executor', where 'ex-' meant 'out' and 'sequi' meant 'to follow'.

'executor' changed from the Old French word 'executour' and eventually became the modern English word 'executor'.

Initially, it meant 'one who follows through with a task', but over time it evolved into its current meaning of 'a person appointed to carry out the terms of a will'.
