Endangered Languages: Why They Disappear and How They Are Saved

There are about 7,000 languages in the world, and many of them are spoken by only a few hundred or a few thousand people. UNESCO estimates that around 40% of all languages are endangered, and linguists warn that half of them could disappear by the end of this century.

Indigenous peoples make up only about 6% of the world’s population, yet they speak more than 4,000 of its languages. When one of these languages stops being passed on to children, a unique way of seeing the world can be lost forever.

Key Takeaways

• Around 40% of the world’s roughly 7,000 languages are considered endangered
• Linguists estimate that half could disappear by 2100
• Indigenous peoples speak more than 4,000 languages
• Hawaiian and Māori show that revitalization is possible
• Documentation, schools and technology all play a role

Understanding Language Extinction

Defining Language Extinction

A language is considered endangered when children are no longer learning it at home. It becomes extinct, or “dormant”, when no fluent speakers remain. With it go stories, songs, place names and knowledge about plants, animals and the land.

The Global Language Landscape

• There are about 7,000 languages worldwide
• Around 40% are endangered, according to UNESCO and Ethnologue
• A large share of languages have fewer than 10,000 speakers
• A handful of major languages are spoken by most of the world’s population

Historical Context of Language Loss

Colonization, forced assimilation, boarding school policies and the pressure to use national or global languages have all contributed to language loss. UNESCO has recorded that around 230 languages became extinct between 1950 and 2010.

“Language is the road map of a culture. It tells you where its people come from and where they are going.” – Rita Mae Brown

The Digital Divide

Only a small fraction of the world’s languages are well supported online, in software and in AI tools. Languages without a digital presence face an extra barrier for young speakers who spend much of their lives online.

Impact of Language Extinction on Indigenous Cultures

Language is central to cultural identity. When a language disappears, communities can lose:

• Unique cultural perspectives
• Traditional ecological knowledge
• Oral histories, songs and stories
• Spiritual and ceremonial practices tied to the language

Loss of Traditional Knowledge

Many indigenous languages contain detailed knowledge about local ecosystems. Studies have shown that much of the world’s remaining biodiversity lies in territories managed by Indigenous peoples, and some words and concepts for plants and animals exist only in their languages.

Examples of Endangered Languages

Around the world, many languages now have only a few elderly speakers, especially in the Americas, Australia and parts of Asia. Linguists are racing to record them before they fall silent.

Language Documentation Projects

Linguists record native speakers, create archives, and produce dictionaries and grammars so that future generations can learn the language even if fluent speakers are gone.

Community-Led Revitalization

Indigenous communities are leading many of the most successful efforts. “Language nest” programs, where young children are cared for entirely in the language, began with Māori kōhanga reo in New Zealand in the 1980s and inspired similar programs in Hawaii.

In the 1980s, fewer than 50 Hawaiian children spoke Hawaiian as a first language. Thanks to immersion preschools and schools, around 18,000 people now report speaking Hawaiian at home.

The Role of Technology

• Smartphone apps for language learning
• Online courses and video lessons
• Digital archives and recordings
• Social media content created by young speakers

Indigenous Languages to Watch in North America

Even relatively large indigenous languages face pressure:

• Navajo: one of the most widely spoken Native American languages, with roughly 170,000 speakers, but fewer young speakers each generation
• Cree: spoken across Canada in several dialects, with tens of thousands of speakers
• Dakota and Lakota (Sioux): a few thousand fluent speakers, with active school and app-based revitalization programs

Many smaller languages in the United States and Canada have only a handful of fluent elders left.

Success Stories

Hebrew, revived as an everyday spoken language in the late 19th and 20th centuries, is the best-known example of a language returning to daily use. Hawaiian, Māori and Welsh show that strong community and school programs can reverse decline.

How Individuals Can Support Language Preservation

Groups like Wikitongues and the Endangered Languages Project help document languages and share recordings. Individuals can support them by donating, sharing content, learning a few words of a local indigenous language or supporting community language programs.
