different between window vs curtainwall

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 Superseded Middle English fenestre, fenester (“window”) borrowed from Old French fenestre (“window”)
