Etymology: The triforium is the arched gallery running above the nave arcade in a church, usually sitting between the arches below and the clerestory windows above. Its name comes from Medieval Latin "triforium", built from "tria" (three) and "for" (opening), with the Latin "-ium" ending. The three openings are the arches that make up the gallery's pattern, so the name describes the architecture itself rather than a person or a legend. The name is a plain descriptive compound, so there is no story behind a coiner or a famous first use. Its meaning stayed fixed to one architectural feature, which makes it a good example of a term built directly from what the eye can see.
