George van Driem had formerly proposed that the Kiranti languages were part of a Mahakiranti family, although specialists are not completely certain of either the existence of a Kiranti subgroup or its precise membership.[1] LaPolla (2003), though, proposes that Kiranti may be part of a larger "Rung" group.
Kiranti verbs are not easily segmentable, due in large part to the presence of portmanteaumorphemes, crowded affix strings, and extensive (and often nonintuitive) allomorphy.
Historical linguists, as early as 2012, do not consider Kiranti to be a coherent group, but rather a paraphyletic one due to lack of shared innovations.[3] Gerber & Grollmann (2018) presented additional evidence supporting the paraphyletic nature of Kiranti. A Central-Eastern Kiranti group is considered to be valid by Gerber & Grollmann (2018), but they consider "Western Kiranti" unclassified within Trans-Himalayan languages.[4]
Grollmann (2023) identifies a Khambu subgroup that consists of three languages, Kulung, Nachiring, and Sampang. Camling may also be a Khambu language.[5]
Research on proto-Kiranti includes work on phonology and comparative morphology by George van Driem,[6] reconstructions by Michailovsky (1991)[7] and Sergei Starostin 1994.[8] Michailovsky and Starostin differ by the number of stop series reconstructed (three vs four) and the interpretation of the correspondences.
Opgenort introduces the reconstruction of preglottalized resonants;[9][10] his reconstruction is generally based on Starostin's four series system. More recently, Jacques proposed a reconstruction of proto-Kiranti verb roots based on Michailovsky's system,[11] and analyzes the other initial correspondences (in particular, the series reconstructed as non-aspirated unvoiced stops by Starostin) as due to morphological alternations and inter-Kiranti borrowing. In addition, he presents a preliminary discussion of the reconstruction of stem alternation and stress patterns on the basis of Khaling and Dumi.[12]
