Sadri Language: at the Munda Community the Largest tribe of Indian Subcontinent

The Munda people speak Mundari/ Nagri/ Sadri language. The Munda tribe are one of the biggest ethnic groups in the Indian Sub-Continent. They have own unique Culture, Food, Flag, Drink (Haria Wine) and Language (Sadri). Now days, they speak Sadri Language but there is no written method (letters). Sadri is mainly spoken in western and central Jharkhand (Ranchi District), but also in parts of Orissa, Chhattisgarh, West Bengal, Assam, Nepal and Bangladesh. estimates the total number of Sadri speakers may be 2,970,000 for 2020. Without a written system, Munda’s culture survives in the intermingling of other cultures. The pre-condition for the development of a nation is to increase the practice of the mother tongue but the Munda could not enrich their culture due to the lack of a written form of the Sadri language. I (Author) have discovered the written form of Sadri Language and the SAMS (NGO) continue to practice that written system in their tribes in different parts of Bangladesh. Gradually spread the Sadri language to their tribes in different countries of the world.
