The "Ganga-Jamuni tehzeeb" is one such instance of the composite culture that marks various regions of the country. Prevalent in the North, particularly in the central plains, it is born of the union between the Hindu and Muslim cultures.

Thus, it came to be known as the Ganga-Jamuni tehzeeb, with the word "tehzeeb" meaning culture.

Urdu nouns and adjective can have a variety of origins, such as Arabic, Persian, Turkish, Pushtu and even Portuguese, but ninety-nine per cent of Urdu verbs have their roots in Sanskrit/Prakrit.

According to Dr Gian Chand Jain, Indo-Aryan languages had three phases of evolution beginning around 1,500 BC and passing through the stages of Vedic Sanskrit, classical Sanskrit and Pali. They developed into Prakrit and Apbhransh, which served as the basis for the formation of later local dialects.
