 The respective languages of all of these modern day branches, bands and tribes, except one, are all closely related variants called Muscogee, Mvskoke and Hitchiti-Mikasuki, all of which belong to the Eastern Muskogean branch of the Muscogean language family.All of these languages are, for the most part, mutually intelligible.The Yuchi people today are part of the Muscogee (Creek) Nation but their Yuchi language is a linguistic isolate, unrelated to any other language.
