An indigenous language or autochthonous language, is a language that is native to a region and spoken by indigenous people. This language is from a linguistically distinct community that originated in the area. Indigenous languages are not necessarily national languages (but they can be; cf. Aymara, which is an official language of Bolivia) and national languages are not necessarily indigenous to the country.
Many indigenous peoples worldwide have stopped passing on their ancestral languages to the next generation and have instead adopted the majority language as part of their acculturation into the majority culture. Furthermore, many indigenous languages have been subject to linguicide (language killing). Recognizing their vulnerability, the United Nations proclaimed 2019 the International Year of Indigenous Languages, "to draw attention to the critical loss of indigenous languages and the urgent need to preserve, revitalize and promote indigenous languages."
Some indigenous languages are disappearing for various reasons, including the mass extinction of entire speaker communities by natural disaster or genocide, aging communities where the language is not passed on, and oppressive language planning policies that actively seek to eradicate languages. In North America, since 1600, at least 52 Native American languages have disappeared. Globally, there may be more than 7,000 languages that exist in the world today, though many of them have not been recorded because they belong to tribes in rural areas of the world or are not easily accessible. It is estimated that 6,809 "living" languages exist in the world today, with 90% having fewer than 100,000 speakers. This means that roughly 6,100 languages are facing a risk of eventual extinction. Some languages are very close to disappearing.
Forty six languages are known to have just one native speaker while 357 languages have fewer than 50 speakers. Rare languages are more likely to show evidence of decline than more common ones.
Oklahoma provides the backdrop for an example of language loss in the developed world. It boasts the highest density of indigenous languages in the United States. This includes languages originally spoken in the region, as well as those of Native American tribes from other areas that were forcibly relocated onto reservations there. The U.S. government drove the Yuchi from Tennessee to Oklahoma in the early 19th century. Until the early 20th century, most Yuchi tribe members spoke the language fluently. Then, government boarding schools severely punished American Indian students who were overheard speaking their own language. To avoid beatings and other punishments, Yuchi, and other Indian children abandoned their native languages in favor of English.
In 2005, only five elderly members of the Yuchi tribe were fluent in the language. These remaining speakers spoke Yuchi fluently before they went to school and have maintained the language despite strong pressure to abandon it.
This situation was not limited to Oklahoma. In the Northwest Pacific plateau there are no speakers left of the indigenous tribal languages from that area, all the way to British Columbia.
Oregon's Siletz reservation, established in 1855, was home to the endangered language Siletz Dee-ni. The reservation held members of 27 different Indian bands speaking many languages. In order to communicate, people adopted Chinook Jargon, a pidgin or hybrid language. Between the use of Chinook Jargon and the increased presence of English, the number of speakers of indigenous languages dwindled.
Other tribes of Native Americans were also forced into government schools and reservations. They were also treated badly if they did not become "civilized". This meant they were to go to Christian churches and speak English. They were forced to give up their tribal religious beliefs and languages. Now, these Native Americans are trying to regain some of their lost heritage. They gather at "Pow-wow" to share culture, stories, remedies, dances, music, rhythms, recipes and heritage with anyone who wants to learn them.
In January 2008, in Anchorage, Alaska, friends and relatives gathered to bid their last farewell to 89 year old Marie Smith Jones, a beloved matriarch of her community. "As they bid her farewell to her, they also bid farewell to the Eyak language as Marie was the last fluent speaker of the language."
In the Isle of Man, following the decline in the use of Manx during the 19th century, Yn Cheshaght Ghailckagh (The Manx Language Society) was founded in 1899. By the middle of the 20th century only a few elderly native speakers remained (the last of them, Ned Maddrell, died on 27 December 1974), but by then a scholarly revival had begun to spread and many people had learned Manx as a second language. The revival of Manx has been aided by the recording work done in the 20th century by researchers.
Hundreds of indigenous languages around the world are taught by traditional means, including vocabulary, grammar, readings and recordings.
The term "treasure language" was proposed by the Rama people of Nicaragua as an alternative to Heritage language, Indigenous language and "ethnic language", names that are considered pejorative in the local context. The term is now also used in the context of public storytelling events.
The term "treasure language" references the desire of speakers to sustain the use of their mother tongue into the future:
[The] notion of treasure fit the idea of something that had been buried and almost lost, but was being rediscovered and now shown and shared. And the word treasure also evoked the notion of something belonging exclusively to the Rama people, who now attributed it real value and had become eager and proud of being able to show it to others.
Accordingly, the term may be considered to be distinct from Endangered language for which objective criteria are available, or Heritage language which describes an end-state for a language where individuals are more fluent in a dominant language.
