'conspirator' originates from Latin, specifically the word 'conspirator', where 'con-' meant 'together' and 'spirare' meant 'to breathe'.

'conspirator' changed from the Old French word 'conspirateur' and eventually became the modern English word 'conspirator'.

Initially, it meant 'one who breathes together', but over time it evolved into its current meaning of 'a person involved in a conspiracy'.
