External relationships
They are not related to the Southern Mishmi Midzu languages, apart from possibly being Sino-Tibetan. However, Blench and Post (2011) suggests that they may not even be Sino-Tibetan, but rather an independent language family of their own.
Blench (2014) classifies the Digaro languages as part of the Greater Siangic group of languages.
