different between window vs shadow

English

Etymology

From Middle English windowe, windohe, windoge, from Old Norse vindauga (“window”, literally “wind-eye", "wind-aperture", "wind-hole”), i.e. ("air-hole"), equivalent to wind +? eye. Cognate with Scots wyndo, wyndok, winnock (“window”), Faroese vindeyga (“window”), Norwegian Nynorsk vindauga, Norwegian Bokmål vindu (“window”), Danish vindue (“window”), Swedish vindöga (“window”), Elfdalian windog and older German Windauge. The “windows” among early Germanic peoples were just unglazed holes (eyes) in the wall or roof that permitted wind to pass through (Can this⁽⁺⁾ etymology be sourced?). Superseded Middle English fenestre, fenester (“window”) borrowed from Old French fenestre (“window”)

Usage notes

• A person (or object) is said to "cast", "have", or "throw" a shadow if that shadow is caused by the person (either literally, by eclipsing a light source, or figuratively). The shadow may then be described as the shadow "cast" or "thrown" by the person, or as the shadow "of" the person, or simply as the person's shadow.
