Languages are more than words—they carry history, identity, and knowledge. Yet today, millions of children are not taught in their mother tongue. For 25 years, International Mother Language Day has promoted linguistic diversity and the right to multilingual education. But challenges remain: 40% of learners worldwide are not taught in the language they speak and understand fluently. In some low- and middle-income countries, this figure rises to 90%. Only 351 languages are used as languages of instruction in education, although 7,000 languages are in use today. To address this, UNESCO is launching new global guidance on multilingual education, offering solutions for inclusive learning. Ministries of Education and key stakeholders are urged to integrate mother-tongue instruction, teacher training, and multilingual learning materials into policies. Let’s make education accessible in all languages and preserve them for future generations. Discover more: https://on.unesco.org/3wu2QD2
