Eastern Indo-Aryan languages

Classification

The exact scope of the Eastern branch of the Indo-Aryan languages is controversial. All scholars agree about a kernel that includes the Odia cluster and the Bengali–Assamese languages, while many also include the Bihari languages. The widest scope was proposed by Suniti Kumar Chatterji who included the Eastern Hindi varieties, but this has not been widely accepted.

When the Bihari languages are included, the Eastern Indo-Aryan languages fall into four language groups in two broader categories:
