Dialects
Bishnupriyas have two dialects, namely Rajar Gang ("King's village") and Madai Gang ("Queen's village"). Unlike the dialects of other tribes, these dialects of Bishnupriya are not confined to distinct geographical areas; they rather exist side by side in the same localities. In Manipur, however, these two dialects were confined to well-defined territories. From the viewpoint of phonetics, Madai Gang is more akin to Assamese and Meitei, whereas Rajar Gang is more akin to Bengali. In vocabulary Madai Gang is more influenced by Meitei while Rajar Gang is more akin to Bengali and Assamese. The morphological differences between the two dialects are negligible.
