The Appalachian dialect is a variation of English.

The distinctive linguistic legacy of the area is reflected in Appalachian English, often known as the Appalachian dialect. Its origins lie in the English dialects that the first settlers brought with them, especially those of German, English, and Scots-Irish ancestry. This dialect differs from Standard American English due to its unique vocabulary, pronunciation, and grammatical characteristics. In addition to incorporating aspects of African American Vernacular English, the Appalachian dialect has been influenced by the historical and cultural events of the area. The region's cultural identity and legacy are influenced by its significant linguistic diversity.
