window
Window is an old Norse “wind-eye,” a practical image for an opening that lets air and light into a room.
Window comes from Old Norse vindauga, literally “wind-eye.” English adopted the compound instead of the older native word eagthyrel, and the Norse image became the everyday name for an opening in a wall.

A detail worth knowing
The word is a small piece of Viking vocabulary that still feels completely ordinary in modern English.
What the evidence supports
Old Norse vindauga combines vindr, wind, with auga, eye. English borrowed it around the beginning of the Middle English period. Early windows could be unglazed openings for air and light, so the compound was concrete rather than poetic decoration.
What the old meaning left behind
The opening became framed and glazed, then metaphorical. Computer windows, launch windows, and windows of opportunity all preserve the core idea of a bounded opening through which something becomes visible or possible.
