'women's' originates from Old English, specifically the word 'wīfmannes,' where 'wīf' meant 'woman' and 'mann' meant 'person.'

'wīfmannes' transformed into the Middle English word 'wymmenes,' and eventually became the modern English word 'women's.'

Initially, it meant 'belonging to a woman,' and this meaning has largely remained the same in modern usage.
