Explanation:

Prime Minister Narendra Modi acknowledged the signing of the Bodo Peace Accord among the Centre, Assam government and Bodo groups by writing these tweets in the Bodo language. The language is one of the key thrust areas in the Bodo Accord. Estimated to have 1.5 million speakers (Census 2011), Bodo is listed in the Eighth Schedule of the Constitution. It is spoken in Assam, where the Bodo tribe constitutes about 5-6% of the population, and in Arunachal Pradesh, Nagaland, Meghalaya, and West Bengal. While Bodo is officially written in the Devanagri script, the language has a history of having been written in at least three different scripts until in 1974, the Government recognised Devanagari as its official script. The 2020 Accord makes Bodo the associate official language throughout Assam. The new Accord also promises to establish a separate directorate for Bodo medium schools, provincialise schools and colleges in the BTAD (Bodoland Territorial Autonomous District) and establish a Cultural Complex-cum-Centre of Excellence named after the late social activist Bodofa Upendranath Brahma in Kokrajhar for protection and promotion of the language.
