'armourer' originates from Old French, specifically the word 'armurier', where 'armure'/'arme' meant 'arms, armor'.

'armourer' changed from the Old French word 'armurier' and entered Middle English as 'armurer', eventually becoming the modern English 'armourer'.

Initially, it meant 'maker or repairer of armor', but over time its use broadened to include 'person responsible for weapons and equipment (especially in military contexts)'.
