'window' originates from Old Norse, specifically the word 'vindauga', where 'vindr' meant 'wind' and 'auga' meant 'eye'.

'vindauga' transformed into the Middle English word 'windowe', and eventually became the modern English word 'window'.

Initially, it meant 'wind eye', referring to an opening for wind, but over time it evolved into its current meaning of 'an opening in a wall or roof for light and air'.
