- early 15c., probably from clere "clear," in a sense "light, lighted" (see clear (adj.)), and story (n.2), though this sense of that word is not otherwise found so early. Originally the upper part of the nave, transepts, and choir of a large church; so called because pierced with windows. Related: Clerestorial.
