However, the Bishnupriya Manipuri language is certainly not one of the Tibeto-Burman languages, but is closer to the Indo-Aryan group of languages with remarkable influence from Meitei both grammatically and phonetically. At a different stage of development of the language the Sauraseni, Maharashtri and Magadhi languages and the Tibeto-Burman languages exerted influence on it as well. So it was probably developed from Sanskrit, Sauraseni-Maharashtri Prakrit and Magadhi Prakrita. The Sauraseni-Maharastri relation can be traced by observing some characteristics of pronouns. The Magadhi element is also remarkable, as the language retains many characteristics of Magadhi. It can further be noted that Bishnupriya Manipuri retains much of the old (15th century to 17th century A.D.) Meitei sound vocabulary, as the majority of speakers of the language, left Manipur during the first part of the 19th century.
