Arched window and Palladian window are not interchangeable terms.
A Palladian window is defined by its triple structure, with the two side units usually smaller than the center one. The center is often taller, and arched, but it doesn’t have to be.
So all arched windows are not Palladian, and all Palladian windows are not arched.
Cap it: The term Palladian comes from Andrea Palladio, a 16th-century Italian architect, so it gets a capital p. (No cap on window.)
