“ DORMER (from Lat. dormire, to sleep) , in architecture, a window rising out of the roof and lighting the room in it: sometimes, however, pierced in a small gable built flush with the wall below, or corbelled out, as frequently in Scotland. In Germany, where the roofs are very lofty, there are three or four rows of dormers, one above the other, but it does not follow that the space in the roof is necessarily subdivided by floors. ”
