Origin & History of “window”

A window is etymologically a ‘wind-eye’ – that is, an ‘eye’-like opening for admitting the air. The word was borrowed from Old Norse vindauga, a compound noun formed from vindr ‘wind’ and auga ‘eye’. Danish vindue is descended from the Old Norse form, which was also taken over by Irish as fuinneog.
