Khasi language is included in

The Khasi language, spoken primarily in the Khasi and Jaintia Hills of Meghalaya, belongs to the Austro-Asiatic language family [1]. This family is traditionally divided into two major branches: the Munda branch, which includes languages like Santhali spoken in central and eastern India, and the Mon-Khmer branch, which includes Khasi and Nicobari [1]. While some modern linguistic classifications propose a three-way split (Munda, Mon-Khmer, and Khasi-Khmuic) or treat Khasian as a primary branch, the standard classification used in Indian academic and administrative contexts identifies Khasi as part of the Mon-Khmer group [1]. This distinguishes it from the Sino-Tibetan family, which encompasses the Tibeto-Himalayan, North Assam, and Assam-Myanmari branches spoken in the Himalayan belt and other parts of the Northeast [2].
