Khasic languages
The Khasic or Khasian languages are a family of Austroasiatic languages native to the Shillong Plateau and spoken by the Khasi, Pnar and other related ethnic groups. Most of them reside in the northeastern Indian state of Meghalaya where Khasi speakers form a plurality of the population. Smaller Khasic-speaking pockets are found in Assam, Manipur, Mizoram and Sylhet Division of Bangladesh.
Languages
Sidwell classifies the Khasian languages as follows.Varieties called Bhoi are dialects of both Pnar and Khasi.
External relationships
Paul Sidwell suggests that Khasian is closely related to Palaungic, forming a Khasi–Palaungic branch.The following eight Khasian-Palaungic isoglosses have been identified by Sidwell.

Reconstruction
Proto-Khasian and Proto-Pnar-Khasi-Lyngngam have been reconstructed by Paul Sidwell. Proto-Khasian is estimated to have originated about 2,000-2,500 years ago, with War splitting from other Khasian linguistic varieties about 1,500 years ago.Proto-Khasian morphology includes a causative *pN- prefix and verbalizing *-r- infix.
The following reconstructed paradigmatic and closed class morphemes in Proto-Khasian are from Sidwell.
