Kera’a is a Trans-Himalayan language traditionally spoken by the Kera’a (Idu Mishmi) in the Lower Dibang and Dibang Valley districts of Arunachal Pradesh, located in disputed territory between India and China. The language is still widely-spoken in the valley by up to 16,000 speakers total, but ongoing cultural, economic and demographic change in the region due to outside forces has led to partial disruption of generational transmission. There are some previously published resources on the language such as phrasebooks, but little audiovisual material is available and no comprehensive grammatical description exists. This report is based on initial field trips to the area in the second half of 2019 and early 2020.
