What does window mean?
A window is principally an opening in a building or vehicle that admits light and provides a view, usually through glass. The word also names a framed area on a computer or other display, where text, images, controls, or other information appear. In contemporary usage, a window can instead mean a limited period during which an activity, appointment, purchase, or opportunity is available, as in “a booking window” or “a window of opportunity.” These meanings share an idea of a defined space or period through which access, visibility, or action is possible. The word is common in formal and informal contexts alike, with specialized meanings in computing, transport, retail, scheduling, and finance. As a verb, it can mean to provide something with a window or to display content in a separate window. Its unusual history gives the ordinary word an appealing literal origin: it comes from a compound meaning “wind-eye,” an opening designed to let in air and light.
An opening in a wall, building, vehicle, or other structure, usually fitted with glass or another transparent material; also a framed display area on a screen or a limited period during which something is available.

Etymology of window
The English word derives from Old Norse vindauga, literally “wind-eye,” formed from vindr, “wind,” and auga, “eye.” The compound referred to an opening in a wall that admitted air and light, and it was borrowed into English with that physical sense. Related forms occur in other Germanic languages, including Danish vindue, Norwegian vindu, Swedish fönster, and German Fenster.
