Urdu, or more properly Odia Hindustani, is the language of the Odia Muslims who speak it as their mother tongue. In its general construction, the dialect is almost indistinguishable from the standard Hindi/Urdu of cities in Eastern India like Kolkata and Patna. However, the spoken dialect has a number of peculiar features due to the influence of Odia. The grammar is somewhat simplified and significant features of a patois are seen. Code switching is common and standard Urdu is always used for writing and formal communication. Most Muslims also speak Odia as a second language. Standard Hindi is the language of recent migrants from North India to Cuttack city.
