Wyandot (also Wyandotte, Wendat, 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 Quebec, Canada. Linguists have traditionally considered Wyandot as a dialect or modern form of Wendat, even though the two are no longer mutually intelligible.

The Delaware languages, also known as the Lenape languages (Delaware: Lënapei èlixsuwakàn), are Munsee and Unami, two closely related languages of the Eastern Algonquian subgroup of the Algonquian language family. Munsee and Unami were spoken aboriginally by the Lenape people in the vicinity of the modern New York City area in the United States, including western Long Island, Manhattan Island, Staten Island, as well as adjacent areas on the mainland: southeastern New York State, eastern Pennsylvania, New Jersey, Connecticut, Maryland, and Delaware.

Cherokee or Tsalagi (Cherokee: ᏣᎳᎩ ᎦᏬᏂᎯᏍᏗ, Tsalagi Gawonihisdi, ) is an endangered-to-moribund Iroquoian language and the native language of the Cherokee people. Ethnologue states that there were 1,520 Cherokee speakers out of 376,000 Cherokees in 2018, while a tally by the three Cherokee tribes in 2019 recorded about 2,100 speakers. The number of speakers is in decline. The Tahlequah Daily Press reported in 2019 that most speakers are elderly, about eight fluent speakers die each month, and that only five people under the age of 50 are fluent. The dialect of Cherokee in Oklahoma is "definitely endangered", and the one in North Carolina is "severely endangered" according to UNESCO. The Lower dialect, formerly spoken on the South Carolina–Georgia border, has been extinct since about 1900. The dire situation regarding the future of the two remaining dialects prompted the Tri-Council of Cherokee tribes to declare a state of emergency in June 2019, with a call to enhance revitalization efforts.
