[Middle English, from Old Norse vindauga : vindr, air, wind; see wē- in Indo-European roots + auga, eye; see okw- in Indo-European roots.]
Word History: The source of our word window is a vivid metaphor. Window comes to us from the Scandinavian invaders and settlers of England in the early Middle Ages. Although we have no record of the exact word they gave us, it was related to Old Norse vindauga, "window," a compound made up of vindr, "wind," and auga, "eye," reflecting the fact that at one time windows contained no glass. The metaphor "wind eye" is of a type beloved by Norse and Old English poets and is called a kenning; other examples include oar-steed for "ship" and whale-road for "sea." Recently we have restored to the 800-year-old word window a touch of its poetic heritage, using it figuratively in such phrases as launch window, weather window, and window of opportunity or vulnerability.

Word Origin & History

chaff 
O.E. ceaf, from P.Gmc. *kaf-, *kef-. Chaffinch (Fringilla cælebs) is O.E. ceaffinc.

window 
c.1225, lit. "wind eye," from O.N. vindauga, from vindr "wind" (see wind (n.)) + auga "eye." Replaced O.E. eagþyrl, lit. "eye-hole," and eagduru, lit. "eye-door." Originally an unglazed hole in a roof, most Gmc. languages adopted a version of L. fenestra to describe the glass version, and Eng. used fenester as a parallel word till mid-16c. Window dressing is first recorded 1790; fig. sense is from 1898. Window seat is attested from 1778. Window-shopping is recorded from 1922. Window of opportunity (1979) is from earlier fig. use in U.S. space program, e.g. launch window (1965).

Bible Dictionary

Window

properly only an opening in a house for the admission of light and air, covered with lattice-work, which might be opened or closed (2 Kings 1:2; Acts 20:9). The spies in Jericho and Paul at Damascus were let down from the windows of houses abutting on the town wall (Josh. 2:15; 2 Cor. 11:33). The clouds are metaphorically called the "windows of heaven" (Gen. 7:11; Mal. 3:10). The word thus rendered in Isa. 54:12 ought rather to be rendered "battlements" (LXX., "bulwarks;" R.V., "pinnacles"), or as Gesenius renders it, "notched battlements, i.e., suns or rays of the sun"= having a radiated appearance like the sun.
