The fissures have been lurking beneath the surface since Independence. All it needed to burst into the surface was a mischievous video showing the burning of Madhu Barnabodha, the grammar primer written by eminent Odia poet Bhaktakabi Madhusudan Rao that has initiated generations into the language. The year-old video was shared on Facebook, on Independence Day, by a group based in western Odisha that refuses to accept Odia as its mother tongue and is fighting for recognition of Koshali, the language spoken in the region.
