[email protected] Abstract Deori is a Tibeto-Burman (henceforth TB) language belonging to the Bodo-Garo sub family [5]. It is spoken in the eastern parts of Assam and some parts of Arunachal Pradesh. It has a population of 41,161 (2001 census) and is spoken by approximately 28,000 people [9]. Deori has been explicitly listed as a „definitely endangered‟ language [9] and as a „severely endangered language‟ [3]. It has been claimed that the linguistic features of Deori has given an individual identity to the language. This paper studies the current use of the lexical tone in Deori and describes the language change attested in the speech of the younger generation speakers. It also presents an overview of the segmental phonology of Deori. Deori has seventeen consonants /p, t, k, b, d, g, m, n, ŋ, tʃ, s, z, h, l, w, r, j/ and has seven oral vowels /a,e,ɛ,i,o,ɔ,u/ and five nasal vowels /ɑ̃,ɛ,̃ ĩ,õ,ũ/. Deori exhibits a process of [ATR] harmony in which vowels in a certain domain (such as „word‟) agree with a [±ATR] feature specification. Presence of contrastive nasal vowel in Deori is considered as a “rare linguistic feature” [2]. It is seen that Deori follows many of the observed processes of vowel nasalization similar to many other languages with nasal harmony. At the same time there are aspects of vowel nasalization in Deori which are not so frequently observed.
