Siouan languages
Siouan languages can be grouped into the Western Siouan languages and Catawban languages. The Western Siouan languages can be divided into Missouri River languages (such as Crow and Hidatsa), Mandan, Mississippi River languages (such as Dakotan, Chiwere-Winnebago, and Dhegihan languages), and Ohio Valley Siouan branches. The Catawban languages consist only of Catawban and Woccon.
Southern Sierra Miwok
Southern Sierra Miwok (also known as Meewoc, Mewoc, Me-Wuk, Miwoc, Miwokan, Mokélumne, Moquelumnan, San Raphael, Talatui, Talutui, and Yosemite) is an Utian language spoken by the Native American people called the Southern Sierra Miwok of Northern California. Southern Sierra Miwok is a member of the Miwok language family along with Lake Miwok, Coast Miwok (extinct), Saclan (extinct), Plains Miwok (extinct), Northern Sierra Miwok and Central Sierra Miwok. The Miwok languages are a part of the larger Penutian language stock. The original territory of the Southern Sierra Miwok people is similar to modern day Mariposa County, California. The Southern Sierra Miwok language is nearly extinct with only a few speakers existing today. However, as of 2012, an active revitalization program is underway.
