Urdu is an Indo-Aryan language spoken mainly in Pakistan and
India, and also in Nepal, Bangladesh and several other countries.
It is also known as Modern Standard Urdu and is described as a
Persianised standard register of the Hindustani language. It is the
national language and lingua franca of Pakistan, where it is also
an official language alongside English. In Nepal, Urdu is a
registered regional dialect and in South Africa it is a protected
language in the constitution.
There are approximately 109 million speakers of Urdu in Pakistan,
15 million of whom speak it as a native language. There were
about 58 million Urdu speakers in India, mainly in Jammu,
Kashmir and Maharashtra states. There were about 738,000
speakers of Urdu in Nepal in 2011, and the language was spoken
by about 250,000 in Bangladesh in 2003. There are also Urdu
speakers in other countries, such as South Africa, Mauritius and
Guyana.
Urdu is the national language of Pakistan and is closely related to
and mutually intelligible with Hindi, though a lot of Urdu
vocabulary comes from Persian and Arabic, while Hindi contains
more vocabulary from Sanskrit. Linguists consider Standard Urdu
and Standard Hindi to be different formal registers both derived
from the Khari Boli dialect, which is also known as Hindustani. At
an informal spoken level there are few significant differences
between Urdu and Hindi and they could be considered varieties a
single language.
Urdu has a few recognised dialects, including Dakhni, Dhakaiya,
Rekhta, and Modern Vernacular Urdu (based on the Khariboli
dialect of the Delhi region). Dakhni (also known as Dakani,
Deccani, Desia, Mirgan) is spoken in Deccan region of southern
India. It is distinct by its mixture of vocabulary from Marathi and
Konkani, as well as some vocabulary from Arabic, Persian and
Chagatai that are not found in the standard dialect of Urdu.
Dakhini is widely spoken in all parts of Maharashtra, Telangana,
Andhra Pradesh and Karnataka. Urdu is read and written as in
other parts of India. A number of daily newspapers and several
monthly magazines in Urdu are published in these states.
Dhakaiya Urdu is a dialect native to the city of Old Dhaka in
Bangladesh, dating back to the Mughal era. However, its
popularity, even amongst native speakers, has been gradually
declining since the Bengali Language Movement in the 20th
century. It is not officially recognised by the Government of
Bangladesh. The Urdu spoken by stranded Pakistanis in
Bangladesh is different from this dialect.
