Dehan dialect

Dehan, Dewan, Dheyan, Dhiyan or Cachari dialect is a regional variety of Assamese, spoken mainly in the Cachar district of Barak valley. More specifically, Dehan speakers are mainly found in ten villages in the eastern part of Barak river namely Horinagar, Japirbon, Leburbon, Gororbon, Dewan (Labok) or Dewan Bosti, Narayanpur, Larchingpar, Thaligram, Lakkhichora, and Digli. Though Dehan speakers are located in the same district, however, they are scattered in different places. Out of ten villages, Japirbon is the biggest and the populous one.

Other than Assamese, Dehan shares its lexical items and linguistic features with Sylheti and Bishnupriya Manipuri as well, which is due to long language contact apart from being closely related. Dehan is closely related to the Kamrupi and Standard dialects of Assamese.
