Kera’a (clk, idum1241, ‘Idu’) is a Tibeto-Burman language spoken by around 12,000 Idu Mishmi
living in Lower Dibang Valley and Dibang Valley, Arunachal Pradesh. The language is currently
threatened (EGIDS 6b), but will likely become endangered due to the disruption of
intergenerational transmission. This talk will outline a preliminary account of the phonology of
Kera’a, and discuss first results of intra- and inter-speaker variation by comparing data from recent
fieldwork to published literature (Jiang 2005, Reinöhl in press).
The linguistic history of Kera’a is not yet clear. While speakers are commonly multilingual in
Kera’a, Hindi and English or Assamese, there is little-to-no knowledge of geographically-adjacent
tribal languages such as Tawrã or Kman. The dialectal situation of Kera’a is clearer, with speakers
identifying two main dialects, Midu and Mithu. Mithu is more conservative, while Midu is more
prestigious and innovative. As a result, Mithu speakers will commonly switch into Midu if they are
not sure whether they will be understood by a Midu speaker. The conservative nature of Mithu,
however, has allowed Reinöhl (in press) to demonstrate regular sound correspondences between
Kera’a and Tawrã. Tawrã is more conservative in contrast to Mithu, as it retains various sets of
initial and final consonants. More recently, the rise of multilingualism in the Dibang Valley has led
to an ongoing shift of younger speakers from Kera’a to Hindi, and to the disruption of
intergenerational transmission of Kera’a.
This linguistic context will inform my analysis of various phenomena found in the segmental
phonology in Kera’a. I will propose a reanalysis of a hypothetical ‘original’ 6-vowel system, still
found in Tawrã, to a 5-vowel system reminiscent of Hindi. I will also discuss ‘free variation’ in the
realisation of the fricatives /s/ and /sh/ and their related affricates /ts~ch/ and /tsh~chh/; the variable
realisation of the consonant cluster /kr/; and the presence of a series of prenasalised consonants,
which is unexpected from an areal perspective.
