Miami-Illinois is a Native American language that belongs to the Algonquian language family. It was historically spoken by the Miami Tribe, primarily located in the regions of present-day Indiana and Ohio. The language is known for its complex verb forms and rich oral traditions. Today, Miami-Illinois is considered a critically endangered language, with few fluent speakers remaining. Efforts are being made by the Miami Tribe of Oklahoma and language revitalization programs to teach and preserve the language for future generations. These initiatives aim to reconnect younger members of the tribe with their cultural heritage.
