Rhymes with DORMER


noun    (Concise Encyclopedia)

Window set vertically in a structure that projects from a sloping roof. It often illuminates a bedroom. In the late Gothic and early Renaissance periods, elaborate masonry dormers were designed. Dormers were used along with the mansard roof to defy a Parisian law limiting buildings to six stories; the seventh story was called a garret (or attic) and was made habitable by the dormer. See also gable.
