Vulgarity is the quality of being common, coarse, or unrefined. This judgement may refer to language, visual art, social classes, or social climbers. It may never be self-referential because, to be aware of vulgarity is to display a degree of sophistication which thereby elevates the subject above the vulgar. From the fifteenth to seventeenth centuries, “vulgar” simply described the common language or vernacular of a country.
