Cognate with Scots windae and windock, Faroese vindeyga, Norwegian Bokmål vindu, Norwegian Nynorsk vindauge, Danish vindue, archaic Swedish vindöga, Elfdalian windog. Displaced native Old English ēagþȳrel (literally “eye hole”) (the rare direct descendant is eyethurl (“window, pupil, etc.”)). The “windows” among early Germanic peoples were just unglazed holes (eyes) in the wall or roof that permitted wind to pass through .
