Language day origin :
In Bangladesh, February 21 is the anniversary of a pivotal day in the country's history. People lay flowers at a Shaheed Minar
(martyr's monument). They also: purchase glass bangles for themselves
or female relatives; eat a festive meal and organize parties; and award
prizes or host literary competitions. It is a time to celebrate
Bangladesh’s culture and the Bengali language.
The Linguapax Institute, in Barcelona, Spain, aims to preserve and
promote linguistic diversity globally. The institute presents the
Linguapax Prize on International Mother Language Day each year. The
prize is for those who have made outstanding work in linguistic
diversity or multilingual education.
The United Nations' (UN) International Mother Language Day annually
celebrates language diversity and variety worldwide on February 21. It
also remembers events such as the killing of four students on February
21, 1952, because they campaigned to officially use their mother
language, Bengali, in Bangladesh.
