Appalachian English
Appalachian English is the variety of American English native to the central and southern Appalachian region of the Eastern United States. Typically, Appalachian English is classified under the larger family of Southern American English, of whose sound system it shows the most advanced features. The Atlas of North American English identifies the "Inland South" dialect region, in which the Southern dialect vowel shift is the most evolved, as centering around the Appalachian cities of Knoxville and Chattanooga, Tennessee; Birmingham, Alabama; and Asheville, North Carolina. The Appalachian dialect is rhotic and characterized by distinct phonology, morphology, syntax, and lexicon. It is mostly oral but can also be written and appears in some known literary works.
