Tani (alternatively Miric, Adi–Galo–Mishing–Nishi (Bradley 1997), or Abor–Miri–Dafla (Matisoff 2003)), is a branch of Sino-Tibetan languages spoken mostly in Arunachal Pradesh, India and neighboring regions.


The Tani languages are spoken by about 600,000 people of Arunachal Pradesh, including the Adi, Apatani, Galo, Mising, Nyishi, Hill Miri, Tagin, and of the East Kameng, West Kameng, Papumpare, Lower Subansiri, Upper Subansiri, West Siang, East Siang, Upper Siang, Lower Dibang Valley and Lohit districts of Arunachal Pradesh and Dhemaji, North Lakhimpur, etc. districts of Assam. In Arunachal Pradesh alone the Tani-speaking area covers some 40,000 square kilometers, or roughly half the size of the state. Scattered Tani communities spill over the Sino-Indian border into adjacent areas in Mêdog (Miguba people), Mainling (Bokar and Tagin peoples), and Lhünzê (Bangni, Na, Bayi, Dazu, and Mara peoples) counties of Tibet, where together with the non-Tani Idu and Taraon they form the Lhoba nationality.


The Tani languages are conservatively classified as a distinct branch in Sino-Tibetan. Their closest relatives may be their eastern neighbors the Digaro languages, Taraon and Idu; this was first suggested by Sun (1993), but a relationship has not yet been systematically demonstrated. Blench (2014) suggests that Tani has a Greater Siangic substratum, with the Greater Siangic languages being a non-Sino-Tibetan language family consisting of Idu-Taraon and Siangic languages.

Mark Post (2015)[2] observes that Tani typologically fits into the Mainland Southeast Asia linguistic area, which typically has creoloid morphosyntactic patterns,[3] rather than with the languages of the Tibetosphere. Post (2015) also notes that Tani culture is similar to those of Mainland Southeast Asian hill tribe cultures, and is not particularly adapted to cold montane environments.

A provisional classification in Sun (1993), who argued that Tani is a primary branch of Tibeto-Burman (within Sino-Tibetan), is:

To Eastern Tani, van Driem (2008)[4] adds the following possible languages:

Shimong, Tangam, Karko, Pasi, Panggi, Ashing

Milang has traditionally been classified as a divergent Tani language, but in 2011 was tentatively reclassified as Siangic (Post & Blench 2011).

Proto-Tani was partially reconstructed by Sun (1993). A large number of reconstructed roots have cognates in other Sino-Tibetan languages. However, a great deal of Proto-Tani vocabulary have no cognates within Sino-Tibetan (Post 2011), and most Tani grammar seems to be secondary, without cognates in grammatically conservative Sino-Tibetan languages such as Jingpho or the Kiranti languages (Post 2006). Post (2012)[5] suggests that Apatani and Milang have non-Tani substrata, and that as early Tani languages had expanded deeper into Arunachal Pradesh, mixing with non-Tani languages occurred.

Mark Post (2013)[6] proposes the following revised classification for the Tani languages.


Sun (1993: 254-255) lists the following 25 lexical isoglosses between Western Tani and Eastern Tani.
