'prosecutor' originates from Latin, specifically the word 'prosecutor', where 'pro-' meant 'forward' and 'sequi' meant 'to follow'.

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

Initially, it meant 'one who follows up or pursues', but over time it evolved into its current meaning of 'a legal representative who brings charges against someone in a court of law'.
