What is a bow window?

A bow window is defined as a semicircular bay window that typically consists of a series of windows that are joined together to form a curved shape, projecting outwards from the wall of a building. This design allows for more natural light to enter the space and provides a wider view of the outdoors compared to traditional flat windows. Bow windows add aesthetic appeal and can enhance the architectural character of a home while also allowing for additional seating space or flower arrangements inside. The curvature of the bow window differentiates it from a standard bay window, which usually has a more angular shape.

The other choices do not accurately represent the characteristics of a bow window: a flat window lacks the curvature, a window that opens like a door describes a different type of window entirely, and a window located on the roof refers to a skylight, which is not related to the concept of bow windows.
