Global Languages Face Extinction by 2100, Including European and Jewish Tongues

Estimates suggest that between 40% and 50% of the world's approximately 7,000 languages are at risk of disappearing, with some projections indicating up to 90% could vanish by the year 2100. This loss extends beyond words, encompassing unique ways of thinking, knowledge, culture, and identity. The phenomenon affects not only remote communities but also established European nations and Jewish societies.

In Switzerland, Romansh, one of the four national languages, is spoken by about 40,000 native speakers and 60,000 regular users, less than 1% of the population. Despite official status and significant annual government funding, it is classified as "vulnerable to endangered." Factors contributing to its decline include youth migration to German-speaking areas, linguistic fragmentation into five distinct dialects, and the cultural and economic pressure from larger languages.

Ireland faces a similar challenge with the Irish language. While nearly 2 million people claim to know it, only about 72,000 use it daily outside the education system, with just 20,000 in official Irish-speaking regions. Centuries of British rule and the continued dominance of English in economy and popular culture have marginalized Irish. Despite official recognition, bilingual signage, and mandatory schooling, the language is not being passed down to younger generations, risking its symbolic status.

Ladino, the Judeo-Spanish language that emerged in medieval Iberia, is also critically endangered. Once spoken by hundreds of thousands across the Ottoman Empire and beyond, its speakers are now estimated between 50,000 and 130,000, mostly elderly individuals living in Israel. The Holocaust significantly impacted its speaker base. While efforts exist to preserve it, Ladino primarily survives in songs, proverbs, and family memories, with few young speakers acquiring it as a mother tongue.

In France, Breton, a Celtic language spoken in Brittany, is nearly extinct. Once spoken by hundreds of thousands, systematic suppression by the French Republic in the 20th century, which viewed regional languages as a threat to national unity, led to parents ceasing to teach it to their children. Today, an estimated 200,000 speakers remain, the vast majority over 60. Despite bilingual schools and preservation efforts, the language continues to decline, though it was notably featured in France's 2022 Eurovision song.

Hawaiian, a Polynesian language, was once spoken by most island inhabitants. After Hawaii's annexation by the U.S., its use in schools was banned, nearly causing its extinction. By the 1980s, fewer than 50 children spoke it, and adult speakers numbered only a few thousand. A revival effort since then has led to Hawaiian-language immersion kindergartens and official recognition, with an estimated 18,000 to 27,000 speakers today, including learners. However, native speakers remain few, and UNESCO still classifies it as endangered, though it serves as a fragile example of language revitalization.
