Opinions on Tanchangya language
Outside Tanchangya tribe, there is a common belief that there is no difference at all between Tanchangya language and Chakma language. Such an instance can be seen at Dr. Satyakam Phukam’s article named “An Analysis of the Ethno-Linguistic Roots and Connections of the Chakma and Tanchangya People”. According to him, the similarity is much compared to the difference between the words between Chakma and Tanchangya.  In fact, there are some similar derivation and slight modification from “da’ in Chakma language with ‘ra’ in Tanchangya language. Such as hudu jawr?(Chakma) Kuri jawt?(Tanchangya) Where are you going? Hitte idu ejawr? (Chakma) Kiyo pagi iri asyawt? (Tanchangya) Why you are coming here? In these examples, although some similar derivation words are found, each full sentence has a distinct difference in terms of grammatical allocation and complete word.
