Greater Siangic languages
Greater Siangic is a language grouping that includes the Siangic languages, Digaro languages (Idu Mishmi and Taraon) and Pre-Tani, the hypothetical substrate language branch of Tani before it became relexified by Sino-Tibetan. The Greater Siangic grouping was proposed by Roger Blench (2014), based on exclusively shared lexical items that had been noted by Modi (2013).
