The Arapaho language is a member of the Algonquian language family, primarily spoken by the Arapaho people in the United States. It is traditionally used in regions of Wyoming and Colorado, where the Arapaho tribes reside. The language has two main dialects: Northern Arapaho and Southern Arapaho. Arapaho is an endangered language, with efforts underway to revitalize it among younger generations. Language programs and classes are being implemented to teach Arapaho to children, ensuring the preservation of their cultural heritage and identity.
