'armiger' originates from Medieval Latin, specifically the word 'armiger', where 'arma' meant 'arms' and 'gerere' meant 'to bear'.

'armiger' changed from the Medieval Latin word 'armiger' and passed into Middle English (via Anglo-Norman), eventually becoming the modern English word 'armiger'.

Initially, it meant 'bearer of arms' (one who carries weapons), but over time it evolved into its current meaning of 'a person entitled to bear a coat of arms' (a heraldic title).
