This study is a descriptive analysis of the Hajong Noun Morphology, one of the small minority groups living in Assam, Meghalaya, Arunachal Pradesh, West Bengal, and Bangladesh. Applying a descriptive approach and documenting the inflectional noun morphology of Hajong is highly relevant to the preservation of the endangered Hajong language. The study focuses on documenting Hajong noun morphology to contribute to the linguistic record and ensure data accuracy for future research. The result of the study shows that noun morphology in Hajong is mostly aligned with Indo-Aryan (IA) languages of the eastern zone, Bengali, Assamese while retaining a few morphological features from Tibeto-Burman languages. Morphologically, nouns in Hajong are inflected for number, case and can be followed by adjectives, numerals, and quantifiers. Phillips (Northeast Indian linguistics. vol 3, Cambridge, Delhi, pp 2011) covers the wide range of Case Marking in Hajong. However, the present study seeks to examine the various aspects of nominal morphology in Hajong including case marking. The Hajong case formatives have possible cognates from both IA (Assamese, Bangla) and TB languages (Koch, Garo, Bodo) (Phillips in Northeast Indian linguistics. vol 3, Cambridge, Delhi, pp 2011). Pronouns are differentiated by three persons and two numbers. However, the second and third person lacks any formality distinction (honorific and non-honorific) but are inflected for the case. Hajong possesses the natural gender system. A noun phrase in Hajong can be modified by the modifiers. The pre-nominal modifiers include determiners, adjectives, and adjective phrases. Determiners and modifiers precede the head in Hajong. The present data were collected from a total of 12 informants: six informants were aged 24 to 49 from the targeted community, while the other six were 50 years and above from the Goalpara district of Assam.
