International Mother Language Day is observed annually on February 21, celebrating linguistic and cultural diversity worldwide. Organized by UNESCO, the day highlights the importance of preserving the over 7,000 languages spoken globally, many of which are at risk of extinction. The observance began as a tribute to the Bengali Language Movement, which sought official recognition for the Bengali language in Bangladesh. Activities typically include educational efforts to promote language learning and raise awareness about the plight of small linguistic communities. Each year features a specific theme aimed at enhancing these educational initiatives. The day serves as a reminder of the significance of linguistic heritage and the need to protect it for future generations.
