# 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 (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).
| Gloss | Proto-Khasian (Sidwell 2018) | Proto-Palaungic (Sidwell 2015) |
| blood | *snaːm | *snaːm |
| claw/nail | *trʧʰiːm | *rənsiːm |
| hair | *sɲuʔ | *ɲuk |
| man/husband | trmɛ (Amwi) | *-meʔ |
| rain | *slap; slɛ (Amwi) | *clɛʔ |
| swim | *ɟŋiː | *ŋɔj |
| two | *ʔaːr | *ləʔaːr |
| water | *ʔum | *ʔoːm |

## 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).
