Conventionally classified as "Naga," they are not clearly related to other Naga languages, and (with Maringic) are conservatively classified as an independent Tangkhul–Maring branch of Tibeto-Burman, pending further research.
The Maringic languages appear to be closely related to the Tangkhulic family, but not part of it.
[2] some northern villages (Chingjaroi, Jessami, Soraphung Razai) in Tangkhul area have language more closely related to the Angami-Pochuri language group.
Koki, Long Phuri, Makuri, and Para are "Naga" languages spoken in and around Leshi Township, Myanmar.
[4] Mortensen (2003:5-7)[5] lists the following phonological innovations (sound changes) from Proto-Tibeto-Burman (PTB) to Proto-Tangkhulic.
