'battle-ready' originates from the combination of 'battle,' which comes from Old French 'bataille,' and 'ready,' from Old English 'ræde,' meaning 'prepared.'

'battle' changed from the Old French word 'bataille' and eventually became the modern English word 'battle.' 'Ready' evolved from the Old English word 'ræde.'

Initially, 'battle' meant 'a fight or combat,' and 'ready' meant 'prepared.' The combined term 'battle-ready' has retained its meaning of being prepared for combat.
