The two languages are,Arutani Sape

Caddo languageW

Individual dialects are Chemehuevi, which is in danger of extinction, Southern Paiute, and Ute.

Comanche languageW
Comanche language

Comanche is a Uto-Aztecan language spoken by the Comanche people, who split from the Shoshone people soon after the Comanche had acquired horses around 1705.

The language is spoken by the Coushatta people, most of whom live in Allen Parish north of the town of Elton, Louisiana, though a smaller number share a reservation near Livingston, Texas, with the Alabama people. In 1991, linguist Geoffrey Kimball estimated the number of speakers of the language at around 400 people, of whom approximately 350 live in Louisiana. The exact number of current speakers is unclear, but Coushatta Tribe officials claim that most tribe members over 20 speak Koasati. In 2007, the Coushatta Tribe of Louisiana, in collaboration with McNeese State University and the College of William and Mary, began the Koasati (Coushatta) Language Project as a part of broader language revitalization efforts with National Science Foundation grant money under the Documenting Endangered Languages program.

Malecite-Passamaquoddy languageW
Malecite-Passamaquoddy language

Malecite–Passamaquoddy is an endangered Algonquian language spoken by the Maliseet and Passamaquoddy peoples along both sides of the border between Maine in the United States and New Brunswick, Canada. The language consists of two major dialects: Malecite, which is mainly spoken in the Saint John River Valley in New Brunswick; and Passamaquoddy, spoken mostly in the St. Croix River Valley of eastern Maine. However, the two dialects differ only slightly, mainly in accent. The indigenous people widely spoke Malecite-Passamaquoddy in these areas until around the post-World War II era when changes in the education system and increased marriage outside of the speech community caused a large decrease in the number of children who learned or regularly used the language. As a result, in both Canada and the U.S. today, there are only 600 speakers of both dialects, and most speakers are older adults. Although the majority of younger people cannot speak the language, there is growing interest in teaching the language in community classes and in some schools.

Massachusett languageW

Nez Perce languageW
Nez Perce language

Nez Perce, also spelled Nez Percé or called Nimipuutímt, is a Sahaptian language related to the several dialects of Sahaptin. Nez Perce comes from the French phrase nez percé, "pierced nose"; however, Nez Perce, who call themselves Nimiipuu, meaning "the people", did not pierce their noses. This misnomer may have occurred as a result of confusion on the part of the French, as it was surrounding tribes who did so.

The immersion school has since closed its doors and the language program now operates through the Cultural Resource Department for the Washoe Tribe. The language is still very much endangered; however, there has been a renaissance in the language revitalization movement as many of the students who attended the original immersion school have become teachers.

The last fluent heritage speaker, Doris Lamar-McLemore, died in 2016, although in 2007 there were three first-language speakers alive.
