The "Southern Dialect" refers to a variety of English spoken in the southern United States. It is characterized by unique pronunciation, vocabulary, and grammar. Common features include the use of "y'all" as a plural form of "you" and the tendency to drop the final "g" in words ending with "-ing," making "going" sound like "goin'." This dialect is influenced by the region's history, including the African American experience and European settlers. Variations exist within the Southern Dialect, such as Appalachian English and Gullah, reflecting the diverse cultural backgrounds of the speakers.
