Huron-Wyandot

Wyandot (Waⁿdátcode: wya is deprecated , also Wendat, Wyandotte, Quendat or Huron) is the Iroquoian language traditionally spoken by the people known as Wyandot or Wyandotte, descended from the Tionontati. It is considered a sister to the Wendat language, spoken by descendants of the Huron-Wendat Confederacy. It was last spoken, before its revival, by members located primarily in Oklahoma, United States, and Ontario, Canada. Linguists have traditionally considered Wyandot as a dialect or modern form of Wendat, even though the two are no longer mutually intelligible.

Wyandot essentially died out as a spoken language with the death of the last native speaker in 1972, though there are now attempts at revitalization:

The Wyandotte Nation is offering Wyandot language classes in the Wyandotte Public Schools grades K–4, at the Wyandotte Nation's preschool "Turtle-Tots" program in Oklahoma and has created online language lessons for self-study.
