Windows

The term comes from the Latin ventus (wind), referring to the ventilation capacity it provides. Formerly the window was also called fenestra or also called "finistra", identically to how it is called in Latin and Greek. This would be the direct mode of etymological derivation.

The Romans were the first to use glass for windows, a technology that was probably first produced in Roman Egypt, in Alexandria around AD 100. C. Paper windows were inexpensive and widely used in ancient China, Korea, and Japan. In England, glass became common in windows of ordinary houses only at the beginning of the 17th century, while windows made of panes of flattened animal horns were used as early as the 14th century. In the 19th-century American West, roaming tribes began to use oiled paper windows. Modern-style floor-to-ceiling windows were only possible after the industrial plate glass manufacturing processes were fully perfected.
