The Eskimo-Aleut language family consists of two main branches: Eskimo and Aleut. The Eskimo branch includes languages such as Inuit and Yupik, spoken by indigenous peoples in the Arctic regions of North America and Greenland. The Aleut branch is primarily spoken in the Aleutian Islands of Alaska. These languages are characterized by their complex morphology and rich vocabulary, particularly in terms of describing the environment and hunting practices. The Eskimo-Aleut languages are primarily spoken by small, indigenous communities, and efforts are ongoing to preserve and revitalize these languages in the face of modernization and language shift.
