Bengali–Assamese languages in the context of "Tangchangya language"

Bishnupriya Manipuri, also known as Bishnupriya Meitei or simply as Bishnupriya, is an Indo-Aryan lect belonging to the Bengali–Assamese linguistic sub-branch. It is a creole of the Bengali language and the Meitei language (also called Manipuri language) and still retains its pre-Bengali features.

It is spoken in parts of the Indian states of Assam, Tripura, and Manipur, as well as in the Sylhet Division of Bangladesh, and uses the Bengali-Assamese script as its writing system. Bishnupriya Manipuri is a member of the Eastern Indo-Aryan languages and evolved from Magadhi Prakrit; hence its origin is associated with the Magadha realm.
