Mundari Bani (Mundari: Bani 'alphabet', also known as Mundari Bani Hisir Hisir 'writing', Nag Mundari, or the Mundari alphabet) is the writing system created for the Mundari language, spoken in eastern India. Mundari is an Austroasiatic language. Mundari Bani has 27 letters and five diacritics, the forms of which are intended to evoke natural shapes. The script is written from left to right.
Community elder and author Rohidas Singh Nag invented and published in late 1980 the alphabetic writing system Mundari Bani, which has seen limited but increasing use in literature, education, and computing.
Rohidas Singh Nag started designing the initial characters of Mundari bani in 1949 while in grade school, which he wrote on the walls using clay. By 1953 he had finished a set of 35 characters. He further simplified the alphabet in 1980 by reducing it to 27 alphabetical characters. In 2008 Bharat Munda Samaj, Mundari Samaj Sanwar Jamda and Nag reformed the script in styling and adding glyphs. Since then, fonts were developed using this standard.
Nag presented the alphabet in the 1980s to then-Chief Minister of Odisha Janaki Ballabh Patnaik and submitted a memorandum to recognize the Munda language constitutionally. Nag along with others submitted a memorandum to the then president of India in 1999 appealing again for the constitutional recognition. "Mundari Samaj Sanwar Jamda", a social organisation of the Munda community based in Poda Astia, Mayurbhanj has been demanding to incorporate the Munda language in the Eighth Schedule to the Constitution of India, to air Munda language through All India Radio, and establish a Munda language department at North Odisha University for higher studies on the basis of the writing system and literature. The writing system has seen limited but increasing use in literature, education, and computing.
Since the 2008 edits, Mundari Bani has 27 alphabetical characters, five diacritics, ten (decimal) digits. Their names follow traditional names. It uses Latin-script punctuation like period and comma.
