Northern Kuki-Chin languages

Northern Kuki-Chin (or Northeastern Kuki-Chin) is a branch of Kuki-Chin languages. It is called "Northeastern Kuki-Chin" by Peterson (2017) to distinguish it from the Northwestern Kuki-Chin languages. VanBik (2009:31) also calls the branch "Northern Chin" or "Zo".
Except for Thado speakers, most Northern Kuki-Chin speakers self-identify as part of a wider Zomi ethnic group.
