Hindustani language

• 1. A Language With Two Faces

  ›

  Hindustani is the language that 855 million people speak, yet many of them insist they are speaking something else. As of 2025, Hindi and Urdu together rank as the third-most-spoken language in the world, behind only English and Mandarin, according to Ethnologue. The same words leave a speaker's mouth in Lucknow and in Varanasi, and the same question, "How much is this?", carries identical sounds across North India and Pakistan. Yet write it down in Lucknow and you reach for the Perso-Arabic script. Write it in Varanasi and you reach for Devanagari. The spoken thing is one. The written thing splits in two. This is a language with a shared grammar and a divided soul, a single voice that answers to the names Hindi, Urdu, and Hindi-Urdu depending on who is listening. How did one tongue come to wear two scripts, two religions, and two national flags? Why did Mahatma Gandhi champion it as a bridge while later generations boycotted films for using too much of one half? And what does it mean that the colloquial speech of Bollywood cannot be cleanly called either Hindi or Urdu?

• 2. Born In The Doab

  ›

  Around the Ganges-Yamuna Doab, in the cluster of Delhi, Meerut, and Saharanpur, a contact language took shape from the apabhraṃśa vernaculars of the 7th to 13th centuries. Its base was the Western Hindi dialect called Khariboli, and that base supplied the grammar and the core Sanskritic and Prakritic vocabulary that the language never lost. The increasing linguistic diversity of the Muslim period in the subcontinent pressed these older speech forms into a common tongue.

  Amir Khusrow, writing in the thirteenth century during the Delhi Sultanate, used these forms and called them Hindavi. He referred to the same speech as Dehlavi, meaning 'of Delhi', and Sufis carried it across the subcontinent to spread their message. The Delhi Sultanate itself stretched across most of today's India, eastern Pakistan, southern Nepal, and Bangladesh, knitting Hindu and Muslim cultures into contact.

  The military exploits of Alauddin Khalji pushed the language southward into the Deccan by the end of that century. There it grew a southern dialect, Deccani, promoted by Muslim rulers in the region. The names multiplied: Hindui, Hindavi, Zabān-e Hind, Rekhta, Hindi. In Gujarat it was Zabān-e Gujari; in southern India, Zabān-e Dakhani; around Delhi, Zabān-e Dehlavi. The Delhi Sultanate, a run of Turkic and Afghan dynasties, gave way to the Mughal Empire in 1526.

• 3. The Persian Tide

  ›

  Babur's successors ruled as Persianised emperors, though the Mughals were of Timurid Turco-Mongol descent. Persian gradually became the state language of the Mughal Empire, building on the Turko-Afghan Delhi Sultanate that had first introduced Persian to the subcontinent. This patronage reinforced Persian among the Central Asian Turkic rulers, even as the local vernacular kept absorbing its influence.

  Hindustani took shape as a Persianised vernacular across the Delhi Sultanate, dated 1206 to 1526, and the Mughal Empire, dated 1526 to 1858. It kept the Khariboli grammar and Sanskritic core, but swallowed large numbers of Persian, Arabic, and Turkic loanwords. The contact of Hindu and Muslim cultures in Hindustan produced a composite Ganga-Jamuni tehzeeb. The language earned the name Rekhta, meaning 'mixed', because its Prakritic base now ran through with Persian.

  Hybridization built new compound words from two worlds. Rajmahal, meaning 'palace', joined the Khari Boli raja, 'royal', to the Persian mahal, 'house'. Rangmahal paired rang, 'colour', with the same mahal. Hindustani contains around 5,500 words of Persian and Arabic origin, and Persian prefixes became so assimilated they attached even to original Khari Boli words. Written in Perso-Arabic, Devanagari, and occasionally Kaithi or Gurmukhi, it served as the lingua franca of northern India for four centuries. Its centres of development ran from the Mughal courts of Delhi, Lucknow, Agra, and Lahore to the Rajput courts of Amber and Jaipur.

• 4. Language Of The Camp

  ›

  Zabān-e Urdū-e Mualla meant 'language of the court', and from it came a name that now marks a national identity. In the 18th century, as the Mughal empire fragmented, a Delhi variant of Hindustani gradually replaced Persian as the lingua franca of the educated elite in northern India. Its Perso-Arabic form underwent standardisation and further Persianisation, and emerged as Urdu.

  The word's deeper root reaches into Chagatai, Ordū, meaning 'camp', cognate with the English word horde. Urdu began as the common speech of the Mughal army, and in local translation it was the Lashkari Zabān, the military language, shortened to Lashkari. The name Urdu itself appeared around 1780. It is believed to have been coined by the poet Mashafi, the first person to trim Zabān-i-Ordu down to simply Urdu.

  Amīr Khusrau Dehlavī, whose 13th and 14th century works mark the earliest literature of the language, is often called the "father of Urdu literature". Walī Deccani is seen as the progenitor of Urdu poetry. As a literary language, Urdu took shape in courtly, elite settings, and alongside English it became an official language of northern parts of British India in 1837.

• 5. The Sanskrit Counterweight

  ›

  Hindi as a standardised literary register arose in the 19th century, the deliberate counterweight to Urdu's Persian. The first literary works in Sanskritised Hindustani, mostly translations, appeared in the early 19th century, written by both Hindu and Muslim authors including Lallu Lal and Insha Allah Khan. The call for a distinct Sanskritised standard, written in Devanagari and named Hindi, grew politicised through the century.

  Around 1880, that call gained pace, driven by an effort to displace Urdu's official position. Standard Hindi draws heavily on Sanskrit and to a lesser extent Prakrit, while keeping the same Prakritic grammar and base vocabulary as Urdu. The formal, official Hindi advocated by Purushottam Das Tandon, and instituted by the post-independence Indian government, leans heavily on Sanskrit.

  John Fletcher Hurst, in a book published in 1891, recorded that philologists did not regard Hindustani as a distinct language but as a dialect of Hindi with an admixture of Persian. He still granted it weight, calling it the linguistic result of Muslim rule and noting it was spoken by Hindus in North India and by the Muslim population across India. Next to English, it was the official language of the British Indian Empire, written in Arabic or Persian characters, and spoken by roughly 100,000,000 people.

• 6. Naming And Unnaming

  ›

  John Borthwick Gilchrist published "A Grammar of the Hindoostanee Language" in 1796, fixing the British habit of treating the speech as a single named thing. British officials used the words Hindustani, Hindi, and Urdu interchangeably, and developed the language as the administration of British India. They prepared it, in effect, to become the official language of two future nations.

  Grierson, in his Linguistic Survey of India, pushed back against the overlapping synonyms. He proposed that Hindustani name the language of the Upper Gangetic Doab and the lingua franca of India, writable in both Persian and Devanagari without purism. Urdu, he wrote, should be confined to the variety in which Persian words occur frequently, and which can only be written in the Persian character. Hindi he confined to the variety abounding in Sanskrit words, written only in Devanagari.

  Before 1947, the British Raj officially recognised Hindustani. With partition, India and Pakistan established national standards called Hindi and Urdu and tried to make them distinct. The term Hindustani lost currency, replaced by Hindi and Urdu, or by Hindi-Urdu when either was too specific. The unintended result was that Hindustani came to be seen, mistakenly, as a "mixture" of the two.

• 7. Travels And Mutations

  ›

  In the Deccan, Hindustani blended with Telugu and became Dakhani, where aspirated consonants softened into their unaspirated counterparts. Dekh, 'see', became dek; ghula, 'dissolved', became gula; kuch, 'some', became kuc; and samajh, 'understand', became samaj. As Muslim rule expanded, speakers traveled as administrators, soldiers, merchants, and artisans, and the language hybridized with each local tongue it reached. Hyderabadi Urdu, spoken around the capital of the Nizams and the Deccan Sultanates, stands as the prestige dialect of this southern line.

  Fiji Hindi descended from the Hindustani group and is spoken widely by Fijians of Indian origin. During British rule in Burma, Hindustani was spoken widely, and many older citizens of Myanmar, particularly Anglo-Indians and the Anglo-Burmese, still know it, though it has held no official status since military rule began. In Canada, Hindustani ranks among the fastest growing languages, and it travels through the South Asian diaspora into Europe, the Middle East, and the Gulf Cooperation Council states.

  A sizeable population in Afghanistan, especially in Kabul, can speak and understand Hindi-Urdu, drawn in by the popularity of Bollywood films and songs. Many Afghan refugees also spent time in Pakistan during the 1980s and 1990s. British rule had earlier seeded English words into the language, and the spread of English as a world language produced a new variant, Hinglish or Urdish.

• 8. The Screen And The Boycott

  ›

  Bollywood, the predominant Indian film industry based in Mumbai, Maharashtra, draws on Standard Hindi, colloquial Hindustani, Bombay Hindi, Urdu, Awadhi, Rajasthani, Bhojpuri, and Braj Bhasha, along with Punjabi and liberal English or Hinglish. The colloquial Hindustani of these films is precisely the speech that cannot be unambiguously identified as either Hindi or Urdu, which is why the word Hindustani now attaches most often to Bollywood.

  The choice between the two registers tracks the story on screen. Historical films set in the Delhi Sultanate or Mughal Empire run almost entirely in Urdu. Films based on Hindu mythology or ancient India lean on Hindi with Sanskrit vocabulary. Film titles are often screened in three scripts at once: Latin, Devanagari, and occasionally Perso-Arabic.

  In recent years, Hindu nationalists have launched boycotts against Bollywood films, partly on the charge that they feature too much Urdu. Some critics reach for the epithet "Urduwood". The unifying language that Mahatma Gandhi once endorsed, precisely because it was tied to neither the Hindu nor the Muslim community, now finds its film industry attacked over which half of itself it leans toward.
