'armipotent' originates from Latin, specifically the word 'armipotens', where 'arma' meant 'arms' and 'potens' meant 'powerful'.

'armipotent' changed from the Medieval/Latin word 'armipotens' and entered English use via late Latin/medieval scholarly usage as the adjective 'armipotent'.

Initially, it meant 'having strength in the arms (physically) or being powerful in war', and over time it has retained the sense of 'possessing physical or military power; mighty'.
