window
Sign in to saveA window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed, or covered in some other transparent or translucent material, a sash set in a frame in the opening. The sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.

A window is an opening in a wall, door, roof, or vehicle that lets light in and may allow sound and air to pass through, typically covered with glass or another transparent material held in a frame.
