## Definition

a small window or room that is built into the sloping roof of a house. It lets more light and air into a room that is under the roof.

For teachers: a window or small room projecting from the sloping roof of a building. It typically has a vertical face and a sloping roof that continues the line of the main roof.

## Examples

- The attic has a small dormer that looks out over the garden.
- To make the attic more livable, the architect added a dormer window to provide natural light and a better view.
- The Victorian house features several ornate dormers that break the monotony of the steeply pitched roofline, allowing for additional living space and improved ventilation in the upper floors.
