Greater Siangic is a language grouping that includes theSiangic languages,Digaro languages (Idu Mishmi andTaraon) andPre-Tani, the hypotheticalsubstrate language branch of Tani before it became relexified by Sino-Tibetan. The Greater Siangic grouping was proposed byRoger Blench (2014), based on exclusively shared lexical items that had been noted by Modi (2013).^[1] Blench (2014) argues that Greater Siangic is an independent language family that has undergone areal influences fromSino-Tibetan languages, and is not a branch of the Sino-Tibetan language family itself.

Various lexical items exclusively shared by Milang, Koro, Taraon, and Idu have also been noted by Modi (2013).^[1] Modi (2013) suggests that Taraon could be closer to Milang than Idu is.

Blench (2014) lists the following languages in Greater Siangic.

Modi (2013: 20-22)^[1] notes the following sound correspondences among Milang, Taraon, Idu, and Proto-Tani.
