Kuki-Chin is alternatively called South-Central Trans-Himalayan (or South Central Tibeto-Burman) by Konnerth (2018), because of negative connotations of the term "Kuki-Chin" for many speakers of languages in this group.
Kuki-Chin is sometimes placed under Kuki-Chin–Naga, a geographical rather than linguistic grouping.
The Karbi languages may be closely related to Kuki-Chin, but Thurgood (2003) and van Driem (2011) leave Karbi unclassified within Sino-Tibetan.
The Kuki-Chin branches listed below are from VanBik (2009), with the Northwestern branch added from Scott DeLancey, et al. (2015), and the Khomic branch (which has been split off from the Southern branch) from Peterson (2017).
The recently discovered Sorbung language may be mixed language that could classify as either a Kuki-Chin or Tangkhul language (Mortenson & Keogh 2011).
Anu-Hkongso speakers self-identify as ethnic Chin people, although their language is closely related to Mru rather than to Kuki-Chin languages. The Mruic languages constitute a separate Tibeto-Burman branch, and are not part of Kuki-Chin.
VanBik (2009)
Kenneth VanBik's (2009:23) classified the Kuki-Chin languages based on shared sound changes (phonological innovations) from Proto-Kuki-Chin as follows.
Peterson's Northeastern branch corresponds to VanBik's Northern branch, while Peterson's Northwestern corresponds to the Old Kuki branch of earlier classifications.
