The Ol Chiki script is used to write Santali (or Santhali), an Austro-Asiatic language spoken by around 7.6 million people mostly in Central and Eastern India. Santali is not an official language in any of India’s states, but is recognised by India’s Constitution. Unlike other Indian scripts, Ol Chiki is an alphabetic script, with distinct letters representing consonants and vowels. Ol Chiki was devised in 1925 by Raghunath Murmu, a native Santali speaker, partially using signs and symbols culturally familiar to Santali speakers. Over the decades, the script gained traction among both native speakers and institutional bodies, and in the 1970s, local schools began teaching Ol Chiki. It was accepted by the Indian government and universities shortly afterwards. In a parallel development, a burgeoning print culture in Ol Chiki emerged, and writing in the script has spread to digital platforms as well. Despite this, only a minority of Santali speakers are literate in Ol Chiki, although this is likely to change.
