Here's a breakdown:
* Old English: The word "window" originates from the Old English word "windūga," which literally means "wind-eye" or "eye of wind." This reflects the fact that early windows were often small, unglazed openings that allowed air to circulate.
* Proto-Germanic: The Old English word "windūga" itself comes from the Proto-Germanic word "*windaugo," which is a combination of "*windaz" (wind) and "*augo" (eye).
* Evolution: Over time, the word evolved from "windūga" to "window" as the design of windows changed and the concept of "wind-eye" became less relevant.
So, while we don't know who first used the word "windūga," we know that its origins lie in the ancient Germanic languages and reflect a fundamental understanding of the function of a window.
