In North America, and worldwide, Indigenous languages are disappearing at an alarming rate. There are, however, models of success for language revitalization in immersion language programs, usually found in tribal colleges and universities. Whether the language learners are tribal college students greeting one another in their native language, kindergarteners seated in a semi-circle around an elder, or people laughing and sharing a meal together, the joy of language learning segues into something serious. The language programs at tribal colleges and within Native communities across North America represent a way for young people to connect more deeply with the past--to understand and speak the words their ancestors uttered, call the features on their homelands by ancient names, and sing traditional prayers with confidence--and to stitch together the threads of a vibrant future for their tribes.
