In a now out-dated survey of languages based on written samples of collected texts that was edited outside of India, George Abraham Grierson, concludes that "[Sylheti's] inflections also differ from those of regular Bengali, and in one or two instances assimilate to those of Assamese," and he groups three dialects of Sylheti (from Western Sylhet, Eastern Sylhet, and Cachar) along with the Bengali dialect of Dacca in an Eastern Bengali group.
