The dialects collectively known as Southern American English stretch across the south-eastern and south-central United States, but exclude the southernmost areas of Florida and the extreme western and south-western parts of Texas as well as the Rio Grande Valley (Laredo to Brownsville). This linguistic region includes Alabama, Georgia, Tennessee, Mississippi, North Carolina, South Carolina, Louisiana, and Arkansas, as well as most of Texas, Virginia, Kentucky, Oklahoma, West Virginia, and northern and central Florida. Southern American English dialects can also be found in extreme southern parts of Missouri, Maryland, Delaware, and Illinois.
