DOR-mer/ˈdɔrmər/

A roofed projection from a sloping roof, usually containing a window.

A small dormer projects from the steep roof above the porch.

A close three-quarter view of a pitched house roof with one clearly projecting gabled dormer: an upright window, short side walls, and its own small roof emerging from the main roof slope.
Etymology

The ‘sleeping room’ connection is architectural: these projecting windows were chiefly found in upper bedrooms. A name for the room thus came to name its roof window.
