A regional dialect or collection of dialects of American English spoken throughout the Southern United States, though increasingly in more rural areas and primarily by White Southerners. The dialect is commonly known in the United States simply as Southern, while formal, much more recent terms within American linguistics include Southern White Vernacular English and Rural White Southern English.
