Shao (2018) notes that mDungnag is not mutually intelligible with either Khams Tibetan or Amdo Tibetan. It may possibly be a divergent form of Amdo Tibetan due to some shared vocabulary, although these similarities could also be due to contact. The exact classification of mDungnag within Tibetic remains uncertain.
Phonology
mDungnag is a non-tonal language.
Dialects
mDungnag can be divided into two dialects:
Hexi 河西 ("West River"): spoken in Baozitan Village 堡子滩村
Hedong 河东 ("East River"): spoken in Qingkedi Village 青稞地村 and Ciyaokou 瓷窑口村 Village. This is the dialect that is primarily documented in Shao (2018).
Some lexical differences between the Hexi and Hedong dialects include the following. Translated English glosses have also been provided to supplement the original Chinese glosses from Shao (2018).
