Braj is a language within the Indo-Aryan language family spoken in the Braj region in Western Uttar Pradesh centered on Mathura. Along with Awadhi, it was one of the two predominant literary languages of North-Central India before gradually merging and contributing to the development of standardized Hindi in the 19th century. It is spoken today in its unique form in many districts of Western Uttar Pradesh, often referred to as 'Central Braj Bhasha'.
