from The Century Dictionary and Cyclopedia
- n. An outer upper light in a perpendicular window, next to the springing of the arch: probably a corruption of angle-light, as these lights are triangular in shape, and are, moreover, in one sense, at the angles of the window. See cut under batement-light.
