Kinship terms and systems are considered to be one of the most resistant parts of language which are constantly in a threat by dominant language. Through these terminologies, we can find out how language not only defines but tries to explain the world view of the native speakers. The kinship terms can also be used to identify and group the specific language with other languages with which it shares its common features under a common phylum. This paper is a study of the kinship terms and systems of Nocte, a Tibeto-Burman language spoken in Arunachal Pradesh. It has also been established as an endangered language. In this paper we look into Nocte Kinship terms, the system, the social structure and its affinity to the Proto-Tibeto-Burman roots.
