What was the language of the Indians in the Appalachian platue?

The Appalachian Plateau is home to various Native American tribes, each with its own distinct language. Tribes such as the Cherokee and Shawnee primarily spoke languages from the Iroquoian and Algonquian language families, respectively. The Cherokee language, still spoken today, uses a unique syllabary developed by Sequoyah in the early 19th century. Other tribes in the region may have spoken different dialects or languages influenced by their cultural interactions.
