Cherokee or Tsalagi (Tsalagi Gawonihisdi, dʒalaˈɡî ɡawónihisˈdî) 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 Cherokee in 2018, while a tally by the three Cherokee tribes in 2019 recorded ~2,100 speakers. The number of speakers is in decline. About eight fluent speakers die each month, and only a handful of people under the age of 40 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.
Around 200 speakers of the Eastern (also referred to as the Middle or Kituwah) dialect remain in North Carolina, and language preservation efforts include the New Kituwah Academy, a bilingual immersion school. The largest remaining group of Cherokee speakers is centered around Tahlequah, Oklahoma, where the Western (Overhill or Otali) dialect predominates. The Cherokee Immersion School (Tsalagi Tsunadeloquasdi) in Tahlequah serves children in federally recognized tribes from pre-school up to grade 6.
Cherokee, a polysynthetic language, is also the only member of the Southern Iroquoian family, and it uses a unique syllabary writing system. As a polysynthetic language, Cherokee differs dramatically from Indo-European languages such as English, French, Spanish, or Portuguese, and as such can be difficult for adult learners to acquire. A single Cherokee word can convey ideas that would require multiple English words to express, from the context of the assertion and connotations about the speaker to the idea's action and its object.
