What does the term casement refer to in architecture?

The term "casement" in architecture specifically refers to a type of window that is hinged on one side and opens outward or inward like a door. This design allows for greater ventilation and can offer unobstructed views, making it a popular choice in both historical and contemporary architecture.

Casement windows are versatile and can be used in various sizes and configurations, often characterized by their aesthetic appeal and functionality. Their ability to open fully allows for better airflow in a room, which is a significant advantage over traditional sliding windows or fixed windows.

The other options represent different architectural elements that do not accurately describe a casement. Decorative arches, door arrangements, and styles of wall paneling all pertain to different aspects of architecture but do not capture the specific nature of what a casement window is.
