This Proto-Prakrit differs from Sanskrit partly in the phonology and the vocabulary which are common to all modern Indo-Aryan vernaculars.
The languages share a virtually identical grammar and also possess a very large body of common vocabulary which consists mainly of words used in everyday, normal conversation.
In additional, although Urdu and Hindi share a large number of colloquial words, formal and literary Hindi and Urdu can differ markedly in terms of vocabulary. For higher registers, Urdu still continues to draw on Perso-Arabic resources, but Hindi turns to Sanskrit.
Considered from a historical point of view, the Hindustani-Hindi-Urdu complex developed out of a common broadly-spoken lingua franca that came to be used through much of north and central India from the late twelfth and early thirteenth centuries during the dynasties of Muslim rulers that pre-dated the Mughal rule. During this time, Persian was in force as the official language of administration and writing but was supplemented by a mixture of the speech of the Delhi area ('Khari Boli', which had Sanskrit as its ultimate ancestor) together with many Persian loanwords as very general means of oral communication among different parts of the Muslim-controlled territories. In the sixteenth and seventeenth centuries, this form of speech was patronized by the rulers of various southern kingdoms and resulted in the growth of an early literature in a language known as Dakhini or southern Hindi-Urdu.
=Elsewhere Gandhi advocated for both Hindi and Hindustani (an amalgam of Hindi and Persianized Urdu that was in use in the north and could be written in either Nagri or Urdu/Persian script). In 1945, Gandhi resigned from the Hindi Sahitya when it advocated that Hindi was to be written exclusively in the Devanagri script. Over time, as both Hindi and Urdu became increasingly linked with Hindu and Muslim identity respectively, Hindustani had few advocates in India with voices powerful enough to drown out the opposition to it, especially after the trauma of partition. Hindi was deliberately Sanskritized to underline its Hindu roots and to create a purer etymology for the language.
According to some, Pakistani Urdu has been following the path of religious fanatics in the last twenty-five to thirty years, removing Hindi words from Urdu and replacing them by Persian and Arabic words. The Arab states of the Persian Gulf, where Pakistanis go in huge numbers to work during several years of their lives and who sponsor the conservative madaris, are taking the blame for this evolution. The foreign labourers returning to Pakistan after several years in Saudi Arabic and neighbouring countries are said to have been indoctrinated by their Arab hosts.
In their formal spoken and written forms, Hindi and Urdu share a common grammar and much basic vocabulary. When Hindi and Urdu are spoken informally by most of the population, the differences present and clearly discernible in formal language tend to disappear to a very significant extent, and the two varieties become both mutually intelligible and often difficult to tell apart. This frequently used, colloquial form of Hindi and Urdu used in everyday conversation by the majority of speakers has in the past regularly been referred to with the term 'Hindustani'. It is also the form of language standardly used in Bollywood films, which are widely enjoyed by speakers of both Hindi and Urdu.
Cartoon Network, Pogo and the rest were available in English also, of course. However, according to a cable operator from Allama Iqbal Town also quoted in the story, Pakistani children preferred their cartoons in Hindi. This is true of India also, where children including those studying in English schools, watch their cartoons only in Hindi.
Then, about seven centuries ago, the dialects of Hindi spoken in the region of Delhi began to undergo a linguistic change. In the villages, these dialects continued to be spoken much as they had been for centuries. But around Delhi and other urban areas, under the influence of the Persian-speaking Sultans and their military administration, a new dialect began to emerge which would be called Urdu. While Urdu retained the fundamental grammar and basic vocabulary of its Hindi parent dialects, it adopted the Persian writing system, "Nastaliq" and many additional Persian vocabulary words. Indeed, the great poet Amir Khusro (1253-1325) contributed to the early development of Urdu by writing poems with alternating lines of Persian and Hindi dialect written in Persian script. What began humbly as a hodge-podge language spoken by the Indian recruits in the camps of the Sultan's army, by the Eighteenth Century had developed into a sophisticated, poetic language. It is important to note that over the centuries, Urdu continued to develop side by side with the original Hindi dialects, and many poets have written comfortably in both. Thus the distinction between Hindi and Urdu was chiefly a question of style. A poet could draw upon Urdu's lexical richness to create an aura of elegant sophistication, or could use the simple rustic vocabulary of dialect Hindi to evoke the folk life of the village. Somewhere in the middle lay the day to day language spoken by the great majority of people. This day to day language was often referred to by the all-encompassing term "Hindustani."
