Lakota language

The Lakota language (Lakȟótiyapi [laˈkˣɔtɪjapɪ]), also referred to as Lakhota, Teton or Teton Sioux, is a Siouan language spoken by the Lakota people of the Sioux tribes. Lakota is mutually intelligible with the two dialects of the Dakota language, especially Western Dakota, and is one of the three major varieties of the Sioux language.

Speakers of the Lakota language make up one of the largest Native American language speech communities in the United States, with approximately 2,000 speakers, who live mostly in the northern plains states of North Dakota and South Dakota. Many communities have immersion programs for both children and adults.

Like many indigenous languages, the Lakota language did not have a written form traditionally. However, efforts to develop a written form of Lakota began, primarily through the work of Christian missionaries and linguists, in the late 19th and early 20th centuries. The orthography has since evolved to reflect contemporary needs and usage.

One significant figure in the development of a written form of Lakota was Ella Cara Deloria, also called Aŋpétu Wašté Wiŋ (Beautiful Day Woman), a Yankton Dakota ethnologist, linguist, and novelist who worked extensively with the Dakota and Lakota peoples, documenting their languages and cultures. She collaborated with linguists such as Franz Boas and Edward Sapir to create written materials for Lakota, including dictionaries and grammars.

Another key figure was Albert White Hat Sr., who taught at and later became the chair of the Lakota language program at his alma mater, Sinte Gleska University at Mission, South Dakota, one of the first tribal-based universities in the US. His work focused on the Sicangu dialect using an orthography developed by Lakota in 1982 and which today is slowly supplanting older systems provided by linguists and missionaries.

The Lakota people's creation stories say that language originated from the creation of the tribe. Other creation stories say language was invented by Iktomi.

A wholly Lakota newspaper named the Anpao Kin ("Daybreak") circulated from 1878 by the Protestant Episcopal Church in Niobrara Mission, Nebraska until its move to Mission, South Dakota in 1908 continuing until its closure in 1937. The print alongside its Dakota counterpart Iapi Oaye ("The Word Carrier") played an important role in documenting the enlistment and affairs including obituaries of Native Sioux soldiers into the army as America became involved in World War I.

Lakota has five oral vowels, /i e a o u/, and three nasal vowels, /ĩ ã ũ/ (phonetically [ɪ̃ ə̃ ʊ̃]). Lakota /e/ and /o/ are said to be more open than the corresponding cardinal vowels, perhaps closer to [ɛ] and [ɔ]. Orthographically, the nasal vowels are written with a following ⟨ƞ⟩, ⟨ŋ⟩, or ⟨n⟩; historically, these were written with ogoneks underneath, ⟨į ą ų⟩. No syllables end with consonantal /n/.
