Blench (2015) suggests that Meyor (Zakhring) and Kman may each be language isolates.[4] Blench argues that the lexical similarities between Kman and Zakhring are borrowings, and that Zakhring had borrowed heavily from Kman and Tibetic, and then later borrowed from Naga languages and Jingpho as well.
Regardless, they are not closely related to the Northern Mishmi also known as Digaro languages.
