Northern Naga languages do not fall within the group, in spite of being spoken by Naga groups; instead, these form part of the Sal languages within Sino-Tibetan,[2] while Southern Naga languages form a branch within Kuki-Chin languages subfamily.[3]
Koki is a "Naga" language spoken in and around Leshi Township, Myanmar that could possibly classify as Tangkhulic languages or Ao languages.
