The Uto-Aztecan languages are a Native American language family. The Uto-Aztecan languages are found from the Great Basin of the western United States (Oregon, Idaho, Utah, California, Nevada, Arizona), through Mexico south to El Salvador. Utah is named after the indigenous Uto-Aztecan Ute people. Classic Nahuatl, the language of the Aztecs, and its modern descendants are part of the Uto-Aztecan family.
