1 Long, narrow, vertical aperture with splayed jambs set in a parapet (sometimes in the merlon of a battlement) or wall for the discharge of arrows, etc., also called arrow-loop, loop-window, or loophole, occasionally with a shorter horizontal aperture across it forming a cruciform opening. The terminations of the apertures (little more than slits in the wall) were often widened into circular holes, and occasionally the point at which the slits crossed was enlarged to a circular opening as well. See gun-loop.
