25 Most Endangered Languages in the World
Every two weeks, a language dies. Not metaphorically — a living, breathing system of human thought, story, and identity vanishes forever, taking with it an irreplaceable lens through which people understood the world. With approximately 7,000 languages spoken on Earth today, linguists estimate that between 50% and 90% of them will disappear by the end of this century. That’s a linguistic catastrophe unfolding in slow motion.
This list of the 25 most endangered languages in the world brings together critically endangered tongues from every corner of the globe — languages with only a handful of speakers left, many of them elderly, and few or no children learning them at home. To build this list, we drew on the UNESCO Atlas of the World’s Languages in Danger, the Endangered Languages Project, and Ethnologue, prioritizing languages classified as Critically Endangered (UNESCO’s highest alarm level before extinction) and those with extremely low speaker counts. The result is a sobering snapshot of humanity’s linguistic heritage on the brink.
Understanding why these languages matter — and why they’re disappearing — is just as important as knowing which ones are at risk. Language isn’t just a communication tool. It encodes medicinal knowledge, ecological wisdom, spiritual traditions, and ways of perceiving time, color, and relationships that no other language captures. When it’s gone, that knowledge goes with it.
The 25 Most Endangered Languages in the World
1. Ainu — Japan
– Approx. Speakers: Fewer than 10 fluent native speakers
– Language Family: Ainu (language isolate)
– Status: Critically Endangered
Spoken on the northern Japanese island of Hokkaido, Ainu has no proven relationship to any other language family on Earth, making it a genuine linguistic isolate. Centuries of Japanese assimilation policies stripped the Ainu people of their land, culture, and language. Japan only officially recognized the Ainu as an indigenous people in 2019. Some revitalization efforts exist, including language classes and cultural festivals, but fluent native speakers can now be counted on two hands.
—
2. Ayapaneco (Zoque-Ayapaneco) — Mexico
– Approx. Speakers: Fewer than 10 fluent speakers
– Language Family: Totonacan
– Status: Critically Endangered
Ayapaneco was once widely spoken in the Tabasco region of Mexico. By 2011, the language had become globally famous for an unusual reason — its last two fluent speakers, Isidro Velazquez and Manuel Segovia, reportedly stopped talking to each other due to a personal feud. The story sparked international attention and, ironically, a revitalization effort. While more community members have since engaged with the language through classes, truly fluent speakers remain critically scarce.
—
3. Chamicuro — Peru
– Approx. Speakers: Fewer than 10
– Language Family: Arawakan
– Status: Critically Endangered
Deep in the Peruvian Amazon, the Chamicuro language clings to life among a handful of elders in the village of Chamicuro near Lake Rimachi. Its speakers have largely shifted to Spanish, and younger generations show little interest in reviving it. Chamicuro is notable for having an unusually rich vocabulary around dreams and supernatural concepts — knowledge that will disappear with the language itself.
—
4. Njerep — Cameroon
– Approx. Speakers: ~4
– Language Family: Bantoid (Niger-Congo)
– Status: Critically Endangered
Njerep is spoken in a small area of the Adamawa Plateau in Cameroon and is considered one of the most endangered languages on the African continent. With only around four known speakers — all elderly — and no active transmission to younger generations, linguists classify it as being on the very edge of extinction. There are currently no significant revitalization programs in place.
—
5. Ongota — Ethiopia
– Approx. Speakers: ~6–12
– Language Family: Afro-Asiatic (possibly a language isolate)
– Status: Critically Endangered
Also known as Birale, Ongota is spoken along the west bank of the Weito River in southwestern Ethiopia. Its linguistic classification has long puzzled researchers — it may be a language isolate or distantly related to Afro-Asiatic languages. All remaining speakers are elderly, and the community has largely shifted to Ts’amakko. Linguist Graziano Sava has worked to document the language before it disappears.
—
6. Liki — Indonesia
– Approx. Speakers: ~5
– Language Family: Austronesian
– Status: Critically Endangered
Spoken on small islands off the northern coast of Papua (West Papua Province, Indonesia), Liki faces extinction as its tiny speaker community ages and younger generations shift to Indonesian or Papuan Malay. Indonesia hosts more endangered languages than any other country on Earth — 425 by Ethnologue’s count — and Liki represents the extreme end of that crisis.
—
7. Paakantyi (Baagandji) — Australia
– Approx. Speakers: ~8
– Language Family: Pama-Nyungan
– Status: Critically Endangered
The Paakantyi people traditionally lived along the Darling River in New South Wales, Australia. Decades of forced displacement, the stolen generations policies, and cultural suppression devastated the language. Australia has 214 endangered languages according to Ethnologue, and Paakantyi is among the most imperiled. Community-led recording projects have helped document vocabulary and stories, offering a foundation for future revitalization.
—
8. Eyak — United States (Alaska)
– Approx. Speakers: 0 native fluent speakers; revitalization efforts ongoing
– Language Family: Na-Dene
– Status: Extinct as a first language / Revitalization underway
When Marie Smith Jones passed away in January 2008, she took with her the last native fluency in Eyak, a language once spoken along the Gulf of Alaska. However, her story didn’t end there. The Eyak Language Project, co-founded with linguist Michael Krauss, documented the language extensively. The Eyak Preservation Council now trains new speakers, making this one of the most moving examples of community-driven revival.
—
9. Siletz Dee-ni — United States (Oregon)
– Approx. Speakers: 1–2
– Language Family: Athabaskan-Eyak-Tlingit (Na-Dene)
– Status: Critically Endangered
The Confederated Tribes of Siletz Indians in coastal Oregon once spoke a unique language now called Siletz Dee-ni. By the 2010s, a single elder was documented as the last fluent speaker. The tribe has since launched intensive language apprenticeship programs, pairing the last speakers with younger tribal members in a race against time to preserve what remains.
—
10. Wintu — United States (California)
– Approx. Speakers: Fewer than 5 fluent speakers
– Language Family: Wintuan
– Status: Critically Endangered
Wintu was historically spoken across the upper Sacramento Valley and Trinity Mountains of Northern California. European colonization, disease, and forced assimilation decimated the Wintu people. The language has an extraordinary grammatical feature — it uses directional suffixes based on cardinal directions rather than the speaker’s perspective, reflecting a deeply different spatial worldview. Revitalization programs exist through local tribal organizations, but fluency remains extremely rare.
—
11. Resígaro — Peru/Colombia
– Approx. Speakers: Likely extinct as a native language
– Language Family: Arawakan
– Status: Possibly Extinct
In 2016, the murder of Rosa Andrade Nole — believed to be one of the last two Resígaro speakers — sent shockwaves through the linguistic community. Her brother Pablo was the only other known speaker. Resígaro, spoken along the Putumayo River region, may now be functionally extinct as a native tongue, though documentation efforts captured some of its structure and vocabulary.
—
12. Kaixana — Brazil
– Approx. Speakers: 1 (possibly none remaining)
– Language Family: Unclassified
– Status: Critically Endangered / Possibly Extinct
Once spoken along the Japurá River in the Brazilian Amazon, Kaixana was reduced to a single known speaker — Raimundo Avelino — as of the mid-2010s. Brazil is home to over 110 endangered languages, many of them Amazonian, where deforestation and the displacement of indigenous communities accelerate language death alongside environmental destruction.
—
13. Nganasan — Russia (Siberia)
– Approx. Speakers: ~125 (2010 census), declining
– Language Family: Uralic (Samoyedic)
– Status: Severely to Critically Endangered
The Nganasan are one of the northernmost indigenous peoples on Earth, living on the Taymyr Peninsula in Siberia. While 2010 census data recorded around 125 speakers, most were elderly, and active use of the language in daily life has severely declined. Soviet-era boarding schools that prohibited indigenous languages did lasting damage, and Russian has become the dominant language even within Nganasan communities.
—
14. Oroqen — China
– Approx. Speakers: ~200, mostly elderly
– Language Family: Tungusic (Altaic)
– Status: Critically Endangered
The Oroqen people, traditionally nomadic hunter-gatherers in the forests of northeastern China (Inner Mongolia and Heilongjiang Province), speak a Tungusic language rich with vocabulary for forest ecology, animal behavior, and shamanic ritual. Government sedentarization policies in the mid-20th century disrupted traditional life, and Mandarin has replaced Oroqen in nearly all daily contexts. The language has no traditional writing system, making oral transmission critical and its decline especially devastating.
—
15. Pazeh — Taiwan
– Approx. Speakers: No native speakers; ~100 semi-speakers in revitalization program
– Language Family: Austronesian (Formosan)
– Status: Extinct / Under revitalization
Pazeh, spoken by the indigenous Pazeh people of central Taiwan, lost its last fully native speaker, Pan Jin-yu, in 2010. However, her death galvanized a remarkable community response. Pan herself spent her final years teaching the language, and her work inspired an ongoing revitalization movement that has produced learning materials, recordings, and a new generation of semi-speakers — proof that even “extinct” languages can be brought back.
—
16. Kallawaya — Bolivia
– Approx. Speakers: ~100
– Language Family: Mixed (Quechuan base with unique lexicon)
– Status: Critically Endangered
Kallawaya is unlike almost any other language on this list. It’s a secret ritual and medicinal language used exclusively by the Kallawaya healer-priests of the Bolivian Andes, traditionally passed from father to son. It encodes thousands of years of pharmaceutical and botanical knowledge. Because it was intentionally kept secret, it was never widely spoken, but its loss would erase an extraordinary body of indigenous medical wisdom.
—
17. Northern Sami — Norway, Sweden, Finland
– Approx. Speakers: ~20,000 (but several Sami languages are critically endangered)
– Language Family: Uralic
– Status: Vulnerable to Critically Endangered (varies by dialect)
The Sami languages form a family across northern Scandinavia and the Kola Peninsula. While Northern Sami has around 20,000 speakers, several sister languages are in dire straits. Ter Sami has just 2 known speakers, Ume Sami has fewer than 20, and Pite Sami is effectively extinct in Sweden. Aggressive assimilation policies known as “Norwegianization” and “Swedification” suppressed these languages for generations, and revitalization efforts vary widely in reach.
—
18. Yup’ik (Naukan) — Russia
– Approx. Speakers: ~100
– Language Family: Eskimo-Aleut
– Status: Critically Endangered
Naukan Yup’ik is distinct from the better-documented Central Alaskan Yup’ik and was traditionally spoken by the Naukan people of the Chukchi Peninsula in Russia’s Far East. The 1958 forced relocation of the Naukan community by Soviet authorities shattered the language’s geographic and social base. Today, roughly 100 speakers remain, almost all elderly, scattered across different settlements without daily contact with each other.
—
19. Ts’ixa — Botswana
– Approx. Speakers: ~200
– Language Family: Kx’a (Khoisan)
– Status: Critically Endangered
Ts’ixa is spoken by a small community in the Okavango Delta of northern Botswana. It belongs to the Khoisan language group — famous for its complex click consonants — and represents unique phonological and grammatical features found nowhere else. Economic pressure, migration to urban centers, and the social dominance of Tswana and Setswana are driving the Ts’ixa community toward language abandonment.
—
20. Yagán (Yaghan) — Chile/Argentina
– Approx. Speakers: 1
– Language Family: Language isolate
– Status: Critically Endangered (effectively moribund)
Yagán was spoken by the indigenous people of Tierra del Fuego, the southernmost archipelago on Earth. Cristina Calderón, known as “the last Yaghan,” is a cultural icon in Chile and the sole remaining fully fluent speaker, born in 1928. Her granddaughter has been learning the language, and documentation projects are underway — but Yagán, an isolated language with no known relatives, hangs by a single thread.
—
21. Aramaic (Eastern Neo-Aramaic dialects) — Iraq, Syria, Turkey
– Approx. Speakers: ~200,000 total Neo-Aramaic speakers, but individual dialects have far fewer
– Language Family: Semitic (Afro-Asiatic)
– Status: Varies; several dialects Critically Endangered
The language of Jesus Christ is not extinct — but it’s dying. Several varieties of Eastern Neo-Aramaic, spoken by Christian and Jewish communities in the Middle East, are now critically endangered. The Jewish Northeastern Neo-Aramaic dialect spoken in Iraqi Kurdistan has fewer than 100 speakers. Wars, genocide, and the mass emigration of Assyrian and Chaldean Christians from Iraq and Syria have devastated communities that kept these dialects alive for millennia.
—
22. Guugu Yimithirr — Australia
– Approx. Speakers: ~200–300 (estimated)
– Language Family: Pama-Nyungan
– Status: Severely to Critically Endangered
Guugu Yimithirr, spoken in Far North Queensland, holds a famous place in linguistic history — it’s the origin of the word “kangaroo,” recorded by Joseph Banks during Captain Cook’s 1770 voyage. More remarkably, it uses absolute cardinal directions (north, south, east, west) for all spatial reference, even for body orientation. This shapes how its speakers think about space in measurably different ways. Despite its cultural significance, the language has very few active speakers today.
—
23. Yuchi (Euchee) — United States (Oklahoma)
– Approx. Speakers: ~5
– Language Family: Language isolate
– Status: Critically Endangered
The Yuchi people of Oklahoma speak a language isolate — completely unrelated to any other known language — that is now on the edge of oblivion. At the turn of the 21st century, only about five elders spoke the language fluently. The Yuchi Language Project has worked intensively to create learning materials, recordings, and teaching programs, but bringing a language back from five speakers requires extraordinary community effort and resources.
—
24. Livonian — Latvia
– Approx. Speakers: ~30 semi-speakers; no fully fluent native speakers
– Language Family: Uralic (Finnic)
– Status: Critically Endangered / Functionally Extinct
Livonian, once spoken by fishing communities along the northern coast of Latvia (the “Livonian Coast”), was declared extinct as a daily spoken language when its last fluent native speaker, Grizelda Kristiņa, died in 2013. However, the Livonian people have refused to let their language disappear permanently. The Livonian Cultural Center actively teaches the language, and several dozen semi-speakers can now converse in it — a fragile but genuine revival.
—
25. Jarawa — India (Andaman Islands)
– Approx. Speakers: ~380
– Language Family: Andamanese (language isolate)
– Status: Vulnerable, but highly at risk
The Jarawa of the South Andaman Islands are one of the last uncontacted or recently contacted tribes in South Asia. Their language — an isolate with no known relatives — remained almost completely undocumented until the tribe began limited contact with the outside world in the late 1990s. While speaker numbers are relatively higher than others on this list, the Jarawa face extreme vulnerability: disease, tourism pressure, and potential cultural assimilation could devastate their community and language within a generation.
Why Are Languages Disappearing?
Globalization and Dominant Languages
Economic opportunity drives language shift faster than almost any other force. When a dominant language — English, Mandarin, Spanish, or Russian — controls access to employment, education, and government services, parents often choose to raise children in that language instead of their heritage tongue. This isn’t a failure of love for their culture; it’s a rational response to systemic pressure.
Assimilation Policies and Intergenerational Breaks
Historically, governments around the world — from Australia’s boarding school system to the Soviet Union’s sedentarization campaigns to the United States’ Indian residential schools — actively suppressed indigenous languages through punishment, forced relocation, and cultural shaming. Even one generation of broken transmission can be enough to push a language into critical endangerment.
Lack of Official Recognition
Languages without official status rarely appear in schools, courts, or media. Without institutional support, speakers have few opportunities to use their language publicly, and it retreats into private, domestic spaces — and then disappears even there.
Migration, Displacement, and Natural Disasters
When communities scatter — through war, economic migration, or natural disasters — the geographic concentration that keeps a language alive dissolves. Speakers separated from each other switch to shared lingua francas, and community languages fade rapidly.
The Impact of Language Loss: More Than Just Words
Language death isn’t just a cultural loss — it’s a cognitive and scientific one. Each language encodes unique ways of categorizing reality: Guugu Yimithirr’s absolute spatial reference system, Wintu’s directional grammar, Kallawaya’s medicinal lexicon. When these disappear, humanity loses cognitive tools that took thousands of years to develop.
Indigenous languages also encode irreplaceable ecological knowledge. Many hold detailed vocabulary for local plant species, animal behavior, weather patterns, and land management — information that’s directly relevant to biodiversity conservation and climate adaptation. Linguists and ethnobotanists have repeatedly found that endangered language communities possess environmental knowledge not recorded anywhere else.
There’s also a profound human rights dimension. The forced suppression of language is an act of cultural violence. When communities lose their languages, they often lose cohesion, identity, and intergenerational bonds — factors directly linked to community health, mental well-being, and cultural continuity.
Efforts to Save Endangered Languages
Language Revitalization Programs
The most successful revivals — Welsh, Hebrew, and increasingly Hawaiian — share a common feature: immersion education. Bringing endangered languages into schools, particularly through immersion programs where subjects are taught entirely in the target language, has proven the most effective method for creating new fluent speakers. Hawaiian went from roughly 1,000 native speakers in the 1980s to a thriving community of tens of thousands who can speak the language today, largely thanks to the Pūnana Leo immersion school movement.
Even Manx Gaelic, declared extinct when its last native speaker died in 1974, has since been revived through immersion education on the Isle of Man. Today, roughly 2,000 people speak it — a modern resurrection of a dead language.
Master-Apprentice Programs
For languages with only a handful of elderly speakers, immersion schools aren’t feasible. The master-apprentice model pairs a fluent elder with a younger community member for hundreds of hours of one-on-one immersive interaction — cooking, fishing, crafting, storytelling — conducted entirely in the endangered language. This approach has been used successfully with several California Native American languages.
Digital Archiving and Documentation
Organizations like the Endangered Languages Project (endangeredlanguages.com), ELDP (Endangered Languages Documentation Programme), and Ethnologue work to record, transcribe, and archive endangered languages before they disappear entirely. Even if a language can’t be revived to daily use, documentation preserves its structure, vocabulary, and recordings for descendants and researchers.
Community-Led Initiatives
The most durable language revitalization happens when communities themselves lead the effort. The Yuchi Language Project, the Eyak Preservation Council, and Taiwan’s Pazeh revival all share this characteristic. External linguists can support, document, and advise, but a language only truly lives when its own community chooses to speak it.
How You Can Help
You don’t have to be a linguist to make a difference for endangered languages. Here’s where to start:
– Explore the Endangered Languages Project at endangeredlanguages.com — you can contribute recordings, translations, or simply learn which languages are at risk in your region.
– Support indigenous communities financially and politically — land rights, cultural autonomy, and economic stability are prerequisites for linguistic survival.
– Advocate for multilingual education policies in your country, including support for minority and indigenous languages in schools.
– Learn about endangered languages in your area — awareness is the first step toward preservation.
– Share this content — platforms like List25 and similar educational outlets play a real role in raising public awareness about issues that academic journals alone can’t reach.
Frequently Asked Questions
How many languages are currently endangered?
The Endangered Languages Project estimates that roughly 3,000 of the world’s approximately 7,000 languages are endangered to some degree. UNESCO’s Atlas of the World’s Languages in Danger lists around 2,500 languages at various stages of endangerment.
What makes a language “critically endangered” according to UNESCO?
UNESCO’s highest pre-extinction category — Critically Endangered — describes languages where the youngest speakers are grandparents and older, the language is not used in daily life, and intergenerational transmission has completely ceased. These languages are typically spoken by fewer than a few dozen elders.
Has any language ever been successfully revived from extinction?
Yes. Hebrew is the most dramatic example — revived from a liturgical language with no native speakers to the official language of Israel with millions of native speakers. Manx Gaelic was declared extinct in 1974 and now has approximately 2,000 speakers. Hawaiian has grown from near-extinction to tens of thousands of speakers through immersion education.
Which country has the most endangered languages?
Indonesia leads with approximately 425 endangered languages, followed by Papua New Guinea (312), Australia (214), and India (197), according to Ethnologue data.
Why do people stop speaking their native languages?
The most common reasons are economic pressure (dominant languages offer better job prospects), historical suppression through government assimilation policies, lack of institutional support (schools, media, courts operate in other languages), and geographic displacement that breaks up speech communities.
Can technology help save endangered languages?
Absolutely. Digital audio and video recording, online dictionaries, language learning apps, social media communities, and AI-assisted transcription are all being deployed for language documentation and revitalization. Technology can’t replace community will, but it dramatically extends the reach and durability of revitalization efforts.
The Languages We Cannot Afford to Lose
The 25 languages profiled here represent the extreme edge of a crisis playing out across every continent. From Yagán at the tip of South America to Liki in the Pacific Islands, from Ongota in the Ethiopian highlands to Yuchi in Oklahoma, each of these languages carries a worldview, a history, and a way of being human that exists nowhere else.
The rate of loss is staggering — one language every two weeks — but so is the human capacity for revival. Hawaiian was nearly gone. Manx was legally dead. Pazeh has no native speakers yet still breathes. The story of endangered languages is not just one of loss; it’s also one of stubborn, beautiful resistance.
Every language that disappears narrows the sum of human knowledge. Every language that survives — or comes back — expands it. That’s a fight worth joining.
