Colville-Okanagan, is a Salish language which arose among the indigenous peoples of the southern Interior Plateau region based primarily in the Okanagan River Basin and the Columbia River Basin in pre-colonial times in Canada and the United States. Following British, American, and Canadian colonization during the 1800s and the subsequent repression of all Salishan languages, the use of Colville-Okanagan declined drastically.
Colville-Okanagan is highly endangered and is rarely learned as either a first or second language. There are about 150 deeply fluent speakers of Colville-Okanagan Salish, the majority of whom live in British Columbia. The language is currently moribund and has no deeply fluent speakers younger than 50 years of age. Colville-Okanagan is the second most spoken Salish language after Shuswap.
History and description 
Historically, Colville-Okanagan originated from a language which was spoken in the Columbia River Basin and is now termed Proto Southern Interior Salish. As a result of the initial expansion of Colville-Okanagan prior to European contact, the language developed three separate dialects: Colville, Okanagan, and Lakes. There is a low degree of dialectic divergence in terms of vocabulary and grammar. Variation is primarily confined to pronunciation.
The vast majority of Colville-Okanagan words are from Proto-Salish or Proto-Interior Salish. A number of Colville-Okanagan words are shared with or borrowed from the neighboring Salish, Sahaptian, and Kutenai languages. More recent word borrowings are from English and French. Colville-Okanagan was an exclusively oral form of communication until the late 19th century when priests and linguists began transcribing the language for word lists, dictionaries, grammars, and translations. Colville-Okanagan is currently written in Latin script using the American Phonetic Alphabet.
In Colville-Okanagan the language itself is known as nsəlxcin or nsyilxcn. Speakers of nsəlxcin occupied the northern portion of the Columbia Basin from the Methow River in the west, to Kootenay Lake in the east, and north along the Columbia River and the Arrow Lakes. In Colville-Okanagan all nsyilxcn speaking bands are grouped under the ethnic label syilx. Colville-Okanagan is the heritage language of the Lower Similkameen Indian Band, the Upper Similkameen Indian Band, the Westbank First Nation, the Osoyoos Indian Band, the Penticton Indian Band, the Okanagan Indian Band, the Upper Nicola Indian Band, and the Colville, Sanpoil, Okanogan, Lakes, Nespelem and Methow bands of the Confederated Tribes of the Colville Reservation.
In 2012, the CBC featured a report on a family which is teaching its children Nsyilxcen in the home.
Four non-profit organizations which support Colville-Okanagan language acquisition and revitalization are the Paul Creek Language Association in Keremeos BC, the En'owkin Centre in Penticton BC, the Waterfalls Immersion School in Omak WA, as well as the Salish School of Spokane in Spokane WA.
