The Khasic or Khasian languages are a family of Austroasiatic languages native to the Shillong Plateau, spoken in the northeastern Indian state Meghalaya and neighbouring areas of Bangladesh.
Languages
Sidwell (2018: 27–31) classifies the Khasian languages as follows. Proto-Khasian War (Amwi, Mnar) Proto–Pnar-Khasi-Lyngngam Lyngngam (former Garo-speakers) Pnar (Jaintia), Khasi, Maharam (Maram)

Varieties called Bhoi are dialects of both Pnar and Khasi.

External relationships
Paul Sidwell (2011) suggests that Khasian is closely related to Palaungic, forming a Khasi–Palaungic branch.

The following eight Khasian-Palaungic isoglosses have been identified by Sidwell (2018: 32).
Lexical innovations
Sidwell (2018: 23) lists the following Khasian lexical innovations (i.e., defining lexical forms) that are found exclusively in the Khasian branch, but not in other Austroasiatic branches).
Reconstruction
Proto-Khasian and Proto-Pnar-Khasi-Lyngngam have been reconstructed by Paul Sidwell (2018). 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 (Sidwell 2018: 20).
Proto-Khasian morphology includes a causative *pN- prefix and verbalizing *-r- infix (Sidwell 2018: 66-67).
The following reconstructed paradigmatic and closed class morphemes in Proto-Khasian are from Sidwell (2018: 51-67).
