International Mother Language Day | Междунаро́дный день родно́го языка́

International Mother Language Day worldwide annual observance held on 21 February to promote awareness of linguistic and cultural diversity and multilingualism. First announced by UNESCO on 17 November 1999, it was formally recognized by the United Nations General Assembly in its resolution establishing 2008 as the International Year of Languages.

Междунаро́дный день родно́го языка́

учреждён решением 30-й сессии Генеральной конференции ЮНЕСКО в ноябре 1999 года и отмечается 21 февраля с 2000 года с целью защиты языкового и культурного многообразия. ЮНЕСКО намерена создать систему превентивного мониторинга, призванную отслеживать состояние языков, находящихся под угрозой исчезновения, и содействовать исправлению ситуации.

По оценкам ЮНЕСКО половина из 6 тысяч языков мира находится под угрозой исчезновения. В 2009 году ЮНЕСКО признала 136 языков на территории России находящимися под угрозой исчезновения.

Генеральная Ассамблея ООН поддержала решение об объявлении Международного дня родного языка (Резолюция № Α/RES/56/262) и призвала государства-членов ООН и Секретариат ООН способствовать защите и сохранению всех языков народов мира. 

International Mother Language Day has been being observed since 2000[4] to promote peace and multilingualism. The date corresponds to the day in 1952 when students from the University of Dhaka, Jagannath University and Dhaka Medical College, demonstrating for the recognition of Bengali as one of the two national languages of East Pakistan, were shot dead by police near the Dhaka High Court in the capital of present-day Bangladesh.

“Mother language” is the calque of a term used in several Romance languages: lengua materna (Spanish), lingua madre (Italian) and langue maternelle (French). The more literal and more common English translation is “mother tongue”, while “native language” has the same meaning and is also in common use. In linguistics, “mother language” refers to an ancestral or proto-language of a language family.

UNESCO chooses a theme for each International Mother Language Day, and sponsors related events at its Paris headquarters on or around 21 February each year. In 2008, the International Year of Languages formally began on International Mother Language Day.

People have shaped the way of celebrating International Mother Language Day. The celebration of the day among with the topic of multilingual diversity has inspired a number of international, national and provincial award ceremonies.
