Indigenous languages are disappearing for various reasons, including the mass extinction of entire speaker communities by
natural disaster or genocide, aging communities in which 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. Additionally, there are over 500 different Indigenous groups in the Americas, yet at least 20 percent of them are estimated to have lost their mother tongue. It was found that among the languages used in 1950, over 75% of them are now extinct or moribund in the United States, Canada, and Australia. Meanwhile, less than 10% of languages in sub-Saharan Africa have gone extinct or are moribund. Small languages have been quantified to have less than 35,000 speakers, and nearly all languages with 35,000 or more speakers have been found to be all growing at around the same rates.
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. That 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
US 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. Reasons for these declines can be attributed to the spread of diseases, such as the measles and smallpox epidemics, forced displacement of inhabitants by settlers, and social, political, and economic isolation and exclusion. Some researchers blame the extinction of language in Australia on a decline in "biolinguistic diversity", a term which identifies a parallel between an area's biodiversity and an area's linguistic diversity. This phenomenon compares the extinction of wildlife upon the introduction of a dangerous predator or extreme change in habitat to the death of Indigenous language upon cultural, social, and environmental changes and forced assimilation. Other tribes of Native Americans were also forced into government schools and reservations. They were also treated badly if they did not become "civilized", which meant they were to go to Christian churches and speak English. They were forced to give up their tribal religious beliefs and languages. Now, 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, they also bid farewell to the
Eyak language as Marie was the last fluent speaker of the language."Overall, there are many different reasons that can lead to the death of languages. The death of all speakers of an Indigenous language can cause languages to become entirely extinct. Much of these deaths occurred during times of colonization, resulting in genocide, war, famine, and the spread of disease. Additionally, the concept of "biolinguistic diversity" is a prevalent phenomenon in academic discussions surrounding linguistic extinction. This concept argues that there are clear similarities between the wildlife extinction due to dangerous environmental alterations and the linguistic extinction due to colonialism, and the forced erasure and replacement of Indigenous language and culture. Finally, restrictive language policies contribute to the death of Indigenous languages, and is a common practice in various regions across the world. Bilingual education and the use of non-dominant languages in educational settings have historically been outlawed in many areas globally, such as Australia, the United States, Serbia, and East Africa. Although some repressive policies have been reversed in more recent years, the impacts of the established restrictive language policies had already taken their toll. == Education and preservation ==
