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.

Tedim is the local lingua franca of northern Chin State, Myanmar, while Thado (also known as Kuki) is the local lingua franca of much of southern Manipur State, India.
