If you grew up hearing Punjabi spoken at home โ€” across kitchen tables in Melbourne, in gurdwaras in Sydney, or down the phone line to grandparents in Jalandhar or Ludhiana โ€” it's easy to take the language for granted. It's just there, the language of family, of jokes, of arguments, of love. But Punjabi carries a history that stretches back more than a thousand years, through empires, religious movements, partitions, and now a global diaspora that spans continents. Understanding where Punjabi comes from doesn't just satisfy curiosity โ€” it gives you a deeper appreciation for why the language sounds, looks, and feels the way it does today, and why preserving it matters so much to communities far from Punjab itself.

Where Punjabi Comes From

Punjabi belongs to the Indo-Aryan branch of the Indo-European language family โ€” the same broad family that includes Hindi, Urdu, Bengali, Gujarati, and Marathi, but also, much more distantly, languages like English, Persian, and Russian. The roots of Punjabi trace back to Sanskrit, the ancient language of the Indian subcontinent, but it didn't emerge directly from Sanskrit in one neat step. Instead, Punjabi evolved through a long chain of related languages and dialects known as Prakrits, and later Apabhramsha โ€” essentially "corrupted" or evolved forms of Sanskrit that were spoken by ordinary people, as opposed to the more formal, literary Sanskrit used by scholars and priests.

By around the 10th to 12th century CE, a distinct language was emerging in the Punjab region โ€” the area now split between Indian Punjab and Pakistani Punjab โ€” that linguists recognise as the early form of Punjabi. This wasn't a sudden invention but a gradual drift: pronunciation shifted, grammar simplified in some ways and became more complex in others, and vocabulary absorbed influences from the many peoples who passed through or settled in the Punjab over the centuries, including Persian and, later, Arabic-influenced terms that arrived with successive waves of rulers from Central Asia and the Middle East.

One of the features that makes Punjabi distinctive among Indo-Aryan languages is its tonal quality. Punjabi is one of the few Indo-Aryan languages to have developed tones โ€” meaning that the pitch at which you say a word can change its meaning, similar in concept (though not in practice) to tonal languages like Mandarin or Vietnamese. This tonal development is thought to have arisen because Punjabi lost certain consonant sounds over time, and the language "compensated" by developing pitch distinctions instead. It's a subtle feature that most native speakers use instinctively without ever thinking about it, but it's one of the things that gives spoken Punjabi its particular musicality.

The Birth of Gurmukhi

No discussion of Punjabi's history can avoid talking about script, because Punjabi has had a complicated relationship with writing systems. For much of its early history, Punjabi was primarily a spoken language. Formal writing in the Punjab region was often done in Persian (the administrative language of the Mughal court) or in Sanskrit-derived scripts used for religious texts in other languages.

That changed in the 16th century with the development of Gurmukhi, the script most associated with Punjabi today. Gurmukhi โ€” meaning "from the mouth of the Guru" โ€” is closely tied to the founding of Sikhism. Guru Angad Dev, the second Guru of the Sikhs, is traditionally credited with standardising and popularising the script in the 1500s, building on earlier regional scripts that had been used in a more ad hoc way. The purpose was significant: Gurmukhi was developed specifically so that the teachings of the Sikh Gurus, and the hymns that would eventually form the Guru Granth Sahib, could be written down and preserved in a script suited to the sounds of spoken Punjabi.

Gurmukhi is what linguists call an abugida โ€” each character represents a consonant with an inherent vowel sound, which can then be modified by additional vowel marks (called matras in Punjabi). The script has 35 primary letters, known as the Painti Akhar, along with additional characters for vowel sounds, nasalisation, and a handful of extra consonants borrowed to represent sounds from Persian and Arabic loanwords. Because Gurmukhi was designed with Punjabi's actual sounds in mind โ€” including its tonal system, which is partly reflected in how certain consonants are written โ€” it remains a remarkably good fit for the language, even five centuries later.

It's worth noting that Gurmukhi isn't the only script ever used for Punjabi. In what is now Pakistani Punjab, Punjabi has historically been written in Shahmukhi, a script based on the Persian-Arabic alphabet. The existence of two scripts for one language is itself a product of history โ€” particularly the religious and political divisions that would later split the Punjab region entirely.

Punjabi Through the Mughal and Colonial Eras

During the centuries of Mughal rule over the Punjab, Persian was the language of administration, courts, and high culture, while Punjabi remained the language of everyday life, folk poetry, and increasingly, religious literature for Sikhs and certain Sufi traditions. This created an interesting linguistic layering that's still visible today: a huge number of everyday Punjabi words have Persian or Arabic origins (think of common words related to government, law, household items, and abstract concepts), sitting alongside a core vocabulary that's much older and more directly inherited from Sanskrit-derived sources.

Despite not being the language of formal power, Punjabi flourished as a language of poetry and storytelling during this period. The qissas (epic romantic poems) of figures like Waris Shah, whose telling of Heer Ranjha became one of the most famous works in the Punjabi literary tradition, date from this era. Sufi poets writing in Punjabi โ€” figures like Bulleh Shah and Shah Hussain โ€” produced verse that's still recited, sung, and quoted across Punjab today, regardless of religion. This period cemented Punjabi's identity as a language of the heart โ€” of love, longing, spirituality, and resistance โ€” even while it lacked official status.

When the British took control of the Punjab in the mid-19th century, the colonial administration largely continued using Persian and later English and Urdu for official purposes, particularly in what would become Pakistani Punjab. This further entrenched a pattern where Punjabi remained the dominant spoken language of the region's population but was sidelined in formal education and administration โ€” a tension that would have lasting consequences after independence.

Partition and a Language Divided

The partition of British India in 1947 was a watershed moment for Punjabi in ways that go beyond the immense human tragedy of the event itself. Punjab was split between the newly created India and Pakistan, and millions of people were displaced along religious lines. This had a direct linguistic consequence: in Pakistani Punjab, Urdu was adopted as the national language and Punjabi's status diminished further in official and educational contexts, even though it remained the most widely spoken language in the country. In Indian Punjab, Punjabi (written in Gurmukhi) eventually became the official state language, particularly after the linguistic reorganisation of Indian states in 1966, which created a Punjabi-speaking majority state.

The result is a situation that can seem puzzling to outsiders: Punjabi is spoken by tens of millions of people on both sides of the India-Pakistan border โ€” in fact, there are more Punjabi speakers in Pakistan than in India โ€” but the language has very different official statuses, is written in two different scripts (Gurmukhi in India, Shahmukhi in Pakistan), and has absorbed somewhat different vocabulary influences depending on which side of the border speakers grew up on. For diaspora communities, especially in places like Australia, this history matters because it shapes which "version" of Punjabi people encounter โ€” most Sikh Punjabi speakers, and most formal learning resources, use Gurmukhi, reflecting the Indian Punjab and Sikh diaspora experience that dominates much of the overseas community.

Punjabi in the Modern World

Today, Punjabi is estimated to have somewhere between 100 and 130 million speakers worldwide, making it one of the most spoken languages on earth โ€” though its global profile doesn't always reflect that scale, partly because of its split status across two countries and its historically lower prestige in formal education compared to Hindi, Urdu, or English.

In Indian Punjab, Punjabi is the language of government, education, and media, and has a thriving literary and film tradition. In Pakistani Punjab, despite being the mother tongue of the majority of the population, Punjabi has had a more difficult path โ€” Urdu and English dominate formal education, and there have been ongoing efforts by activists and educators to promote Punjabi-medium teaching and literacy in Shahmukhi.

Globally, Punjabi has become one of the defining languages of the South Asian diaspora, particularly in the UK, Canada, and increasingly Australia. Migration patterns since the mid-20th century โ€” especially from rural Punjab to cities in these countries โ€” have created vibrant Punjabi-speaking communities that maintain the language not through state institutions, but through families, gurdwaras, community classes, media, and now, increasingly, online content and social media.

What This History Means for You

If you're a heritage speaker trying to (re)connect with Punjabi, or you're a non-Punjabi learner approaching the language for the first time, this history isn't just trivia โ€” it explains a lot about the language as you'll encounter it. It explains why Punjabi sounds the way it does (those tones didn't come from nowhere). It explains why the script matters so much to Sikh identity specifically, and why learning Gurmukhi is often described by community organisations as an act of cultural preservation, not just literacy. It explains why you'll find Persian-derived words sitting comfortably next to Sanskrit-derived ones in everyday speech. And it explains why, for many diaspora families, keeping Punjabi alive feels urgent โ€” because the language has already survived empires, partitions, and shifting borders, and its continued life now depends increasingly on communities outside Punjab itself.

For Australian Punjabi-speaking families, that means the choices made at home โ€” speaking Punjabi with kids, sending them to Saturday language classes, choosing VCE Punjabi, or simply singing along to old folk songs โ€” aren't small things. They're part of a much longer story of a language that has always found a way to keep going, usually through the people who simply kept speaking it.
