Explanation – Pandit Raghunath Murmu, also known as Guru Gomke Raghunath Murmu, was a linguist and a prominent figure in the Santali community. He developed the ‘Ol Chiki’ script in the early 20th century with the goal of providing the Santali language, an Austroasiatic language spoken primarily in eastern India, Nepal, and Bangladesh, with a standardized writing system. The name ‘Ol Chiki’ translates to ‘writing’ or ‘script’ in Santali.
