A window that has a large fixed pane with two operational windows on the sides is best described as?

A window featuring a large fixed pane flanked by two operational windows on the sides is best described as a Chicago Window. This architectural style is characterized by the fixed center pane, which provides uninterrupted views and maximum light, combined with the two smaller operational windows that can be opened for ventilation.

The Chicago Window is emblematic of a specific urban architectural style, often seen in buildings from the late 19th and early 20th centuries, particularly in the Chicago area. Its design is functional and aesthetically appealing, allowing for light to flood into the space while providing flexibility for airflow, which is essential in urban environments.

In contrast, a Bay Window typically consists of a protruding structure from the main wall, often comprising three or more panels that create a nook, which is not the case here. A Double-Hung Window refers specifically to a window with two vertically sliding sashes, allowing for either or both to open, which differs significantly from the fixed and operable design of the Chicago Window. The Sliding Window features panes that move horizontally to open, which also does not align with the description provided.
