It is mainly spoken in Purnia division of Bihar, India.

[2][3] It has almost 11,116 speakers according to the 2011 census of India.

[4][1] It is very similar to the Angika dialect of Maithili, which is spoken in the Bhagalpur and Dumka regions.

Like its neighbor Bengali, it is phonetically characterized by a rounded 'a' sound (halfway between 'a' and 'o', similar to the 'o' in the Bengali name 'Subroto') at the end of certain words.
