The origin of the word 'Naga' is also unclear.[1] A popularly accepted, but controversial, view is that it originated from the Burmese word 'naka' or 'naga', meaning people with earrings. Others suggest it means pierced noses.[3] Both naka and naga are pronounced the same way in Burmese.[4] The ancient name of Nagaland is 'Naganchi', derived from the Naga language. There have been demands by political groups in Nagaland to rename the state to Naganchi.[5]
