Almost all Tani languages are indigenous to central Arunachal Pradesh, including (moving from west to east) the Nyishi, the Apatani, the Tagin, the Galo, the Bokar, the Adi, the Padam, the Pasi, and the Minyong. The Tani languages are noticeably characterised by an overall relative uniformity, suggesting relatively recent origin and dispersal within their present-day area of concentration. Most of the Tani languages are mutually intelligible with at least one other Tani language, meaning that the area constitutes a dialect chain, as was once found in much of Europe; only Apatani and Milang stand out as relatively unusual in the Tani context.
