Sylheti Language Brief History and Facts
Sylheti remains one of the most misunderstood and under-represented languages of South Asia. It is spoken by an estimated twenty million people across north-eastern Bangladesh, India’s Barak Valley and Tripura, and across large diaspora communities in Britain, the Middle East and North America. Despite this, some institutions still mislabel Sylheti as Bengali or as a dialect of Bengali. That claim is not supported by linguistic evidence and has contributed to cultural marginalisation, educational disadvantage and a weakening of identity among Sylheti speakers.
This page sets out the historical, linguistic and logical foundations that establish Sylheti as a distinct language. It dismantles common myths and records the evidence that links Sylheti to its own script, literature and civilisation.
Our Brief History and Heritage
Centuries before colonial boundaries divided the subcontinent and long before the creation of modern nations, the people of Sylhet spoke Sylheti as their native language. Historical accounts record that the last Hindu ruler, Gour Govinda, addressed his subjects in this tongue. When Hazrat Shah Jalal and his companions arrived in the fourteenth century to spread Islam, historical traditions state that they used the local Sylheti tongue so people could understand their message. From the rhythm of village life to the spread of faith, Sylheti served as the living language of the land. No historical record indicates that another vernacular replaced or dominated Sylheti as the main spoken language of Sylhet.

The rulers, poets and scholars of Sylhet left behind a record of a flourishing culture expressed through the Sylheti language. Works attributed to writers such as Talib Husain in the sixteenth century demonstrate a developed literary tradition that predates the formal standardisation of modern Bengali. Historical evidence indicates that a written culture using the Syloti Nagri script, such as Talib Husain’s work from 1549, developed centuries before the nineteenth-century standardisation of the Bengali script by Vidyasagar. The existence of independent Sylheti kingdoms and a distinct administrative history further strengthens the case for linguistic independence. Records suggest that Sylheti was used in religious, legal and daily matters long before Bengal’s broader political and cultural influence reached the region.
The Continuity of Language and the Truth of Sylheti
The absence of evidence for a linguistic shift implies continuity. To suggest that a community changed its language, there must be historical or linguistic evidence of a previous one. In the case of Sylhet, no such evidence exists. History records no other vernacular spoken by its people, nor any indication that Sylheti ever replaced another tongue. It seems historically inconsistent to assume that Sylhet’s people once spoke Bengali, later created an entirely new language and script, and centuries later returned to Bengali again. Such a theory defies both historical logic and human experience.
The truth is simpler yet profoundly tragic. Sylheti did not emerge from Bengali; it has existed alongside it for centuries. What changed was not the language, but the political landscape that redefined it. After the partition of 1947, Sylhet was divided between two states. In East Pakistan, and later in Bangladesh, Bengali became the dominant state language. In India, the Assamese state adopted Assamese as its primary official language, despite the presence of large Sylheti-speaking populations. Within this divided geography, Sylheti itself was left without institutional status or protection. The result was not the natural evolution of language, but the marginalisation of one. Sylheti became not a vanishing tongue, but a victim of history and politics.
The Syloti Nagri Script
The clearest evidence of Sylheti’s linguistic independence is found in its own writing system. The Syloti Nagri script, sometimes referred to as the Sylheti alphabet, was developed to record the distinct tones and sounds of the Sylheti language. The earliest surviving manuscripts date from at least the fifteenth century, although oral and epigraphic evidence suggests that its use may extend further back, possibly to the period of the last independent Sylheti kingdoms.
Syloti Nagri stands apart from both Eastern Nagri, which is used for writing Bengali and Assamese, and Devanagari, which is used for Hindi and several other languages. The structure of Syloti Nagri is entirely its own. It avoids complex conjunct consonants, follows a simplified pattern of vowel markers, and contains characters designed to represent the tonal and phonetic features unique to Sylheti. The script cannot be used to write other languages accurately, as their pronunciation and grammatical forms do not fit within its system. It was created by and for Sylheti speakers alone.
The script became a practical medium of everyday writing for ordinary people, used for religious texts, poetry, correspondence and learning. It made literacy accessible to the wider community and helped preserve cultural expression through a language that truly belonged to the people.
By contrast, Eastern Nagri underwent standardisation much later. In the nineteenth century, Ishwar Chandra Vidyasagar reformed and standardised the Bengali script used for the language. Earlier, in 1743, the Portuguese missionary Manuel da Assumpção had written the first known grammar of the Bengali language, and it was composed in Portuguese rather than in Bengali script. Syloti Nagri was in use several centuries before the modern standardisation of the Bengali script.
No Bengali literary text has yet been found written in Syloti Nagri, and if any ever existed, it would not have reflected correct Bengali pronunciation or grammar. This shows that the script was never intended for Bengali or for any other language. Its very existence stands as clear evidence that Sylheti is not a dialect, but a complete and independent language with its own orthography, grammar and phonology.
Colonial and Post-Colonial Reclassification
The classification of Sylheti as a dialect arose mainly from historical and political factors rather than linguistic ones. In 1874 the British administration moved Sylhet from Assam to the Bengal Presidency for administrative reasons and to connect the tea industry with Calcutta. This administrative decision initiated the process of classifying Sylheti under the broader Bengali category. Standardising languages made colonial rule easier, and the British often grouped several distinct languages under umbrella terms such as “Hindi” or “Bengali”.
When India was partitioned in 1947, Sylhet was divided following a referendum that allowed only two options: to join India or to join Pakistan. Independence or continued British rule was not offered. After Sylhet joined Pakistan, Urdu was promoted and regional languages were de-emphasised through state policy. Although Sylheti was the main language of the area, it did not receive official recognition.
In 1952 Sylhetis joined Bengalis in Dhaka to demand linguistic rights and a multilingual Pakistan. When Bangladesh was formed in 1971 the earlier principle of multilingualism was no longer followed. Bengali alone was declared the official language, and Sylheti was dismissed as a dialect. The people who had fought for linguistic freedom now found their own language excluded from the nation they had helped to build.
Linguistic Roots and Structure
Sylheti belongs to the Eastern Indo-Aryan branch but differs significantly from Bengali in its sound system, morphology and syntax. Many linguists have argued, with good reason, that Sylheti displays tonal features in which changes in pitch can alter meaning, a characteristic not found in Bengali. Bengali speakers unfamiliar with Sylheti often find it difficult to follow its rhythm, especially in rural speech, showing that mutual understanding cannot be assumed.
Sylheti’s vocabulary is wide and distinctive, though many original words have fallen out of use or been replaced by Bangla-influenced forms due to lack of formal documentation and research. Despite its long history, no government programme has ever attempted to record or preserve its linguistic wealth. Only a few independent initiatives, including projects supported by the British Library and community efforts in the UK and India, have tried to preserve and revitalise Sylheti.
In structure and sound pattern, Sylheti is closer to Assamese than Bengali, supporting its recognition as a separate language with its own identity.
Busting Myths: Setting the Record Straight
Myth 1: “Sylheti is just a dialect of Bengali.”
Linguistic evidence shows otherwise. Sylheti has a distinct phonology, morphology and syntax that set it apart from Bengali. It is also one of the few Indo-Aryan languages that display tonal features, where variations in pitch can change meaning, a characteristic that Bengali does not possess. In both grammar and sound structure, Sylheti aligns more closely with Assamese than with Bengali.
Across the world, languages that share common roots are still recognised as independent. French and Italian both descend from Latin. Hindi and Urdu share grammar and much of their vocabulary. Assamese uses the same script as Bengali. Yet each of these languages enjoys full official recognition. To describe Sylheti, which has its own script and tonal features, merely as a dialect is linguistically unsound and logically inconsistent. Readers may refer to the section above for further details.
Myth 2: “Sylheti lacks enough vocabulary to be a full language.”
Sylheti has a deep and flexible vocabulary. Many scholars consider it to have tonal characteristics, as variations in pitch can distinguish meaning and expand expression without multiplying word stems. Any apparent gaps in vocabulary are the result of policy neglect and social pressure, not of linguistic limitation.
For decades, Sylheti has received almost no official recognition, research funding or revival support, and fewer than one per cent of speakers can read or write it in the Syloti Nagri script. Mislabelled books and media often attribute Sylheti words to Bengali or Assamese, while social stigma discourages families from using them. The ongoing Banglanisation of vocabulary, such as the widespread shift from the Sylheti ‘hatkora’ to the Bengali-style ‘shatkora’, reflects social pressure rather than any poverty of language.
No formal government effort has ever been undertaken to record, document or revive Sylheti, not even from within the broader community of its speakers. As the older generation passes away, valuable words fade with them, and the spoken vocabulary narrows. Yet this decline should never be mistaken for linguistic inadequacy. Sylheti has always had, and still has, more than enough words to function as a complete and expressive language.
Some estimates suggest that around thirty to sixty per cent of English vocabulary is of French origin, yet no one questions whether English is a language. Every living language borrows, absorbs and evolves. Bengali itself does not have native words for modern concepts such as computer, internet or megabyte graphics, yet that does not make Bengali any less of a language. Why then should Sylheti, spoken by around twenty million people with a history, grammar and script of its own, be denied the same recognition?
When space is made for teaching, publishing and broadcasting in Sylheti, its richness and expressive power return almost instantly. The language was never lacking. It was only silenced.
Myth 3: “Sylheti does not have its own numerals, therefore it is not independent.”
Numeral systems do not define the identity of a language. English and French both use numerals derived from Latin, yet no one questions their independence. Historically, Sylheti had its own numerals, which were used in manuscripts and commercial records. However, their digital use remains limited because Unicode has not yet included a full set of Sylheti numerals. This is merely a technical limitation, not a linguistic one, and it has no bearing on the independence or authenticity of the language.
There is also some evidence to suggest that Sylhet once had its own unique calendar, although a separate system was not retained in modern times. Many traditional calendars across the region, including the Bengali, Tamil, Nepali and Thai calendars, celebrate their New Year around mid-April, coinciding with the sun’s entry into the constellation Aries (Sankranti). This system most likely originated from ancient Hindu solar timekeeping practices rather than from any single language community. Sylheti too followed a localised version of this calendar, which later became merged with the same system adopted by Bengali speakers. If that shared calendar can now be called the Bengali calendar, Sylhetis have just as much right to refer to it as the Sylheti calendar. The name may have changed, but the heritage remains shared.
Myth 4: “Sylheti is only a regional language or a dialect.”
Calling Sylheti a regional language or a dialect is incorrect. It is spoken by around twenty million people across several countries. In Bangladesh and India alone, this shared language crosses national borders, which by definition makes it an international language. Around eleven million speakers live in Bangladesh, mainly in the Sylhet Division, and about eight million in India’s Barak Valley and Tripura. Large diaspora communities in Britain, the Middle East and North America further extend its global reach.
The idea that Sylheti is a dialect of Bengali has no historical or linguistic foundation. To claim that a people changed their language, there must be proof of an earlier one. In Sylhet’s case, no such evidence exists. History records no other vernacular spoken in the region before Sylheti. It would be illogical to assume that Sylhetis once spoke Bengali, then abandoned it to create their own language and script, only to return to Bengali centuries later.
As discussed above, Sylheti has its own vocabulary, grammar, pronunciation and writing system, distinct from any other language. It bears closer resemblance to Assamese than to Bengali, yet no one calls Assamese a dialect of Bengali. Evidence also indicates that Sylheti may be older than modern Bengali. The Syloti Nagri script dates to at least the fifteenth century, while the modern Bengali script was standardised several centuries afterwards.
Sylheti cannot therefore be described as a dialect. It is an independent and historic language with international presence and a complete linguistic structure.
Myth 5: “Sylheti Cannot Be Endangered Because Millions Speak It.”
A language can still be endangered even if millions speak it. Survival depends not on the number of speakers but on literacy, education and transmission from one generation to the next. Fewer than one per cent of Sylheti speakers can read or write in the Syloti Nagri script, and the language is almost entirely absent from schools, universities, government offices and formal education in both Bangladesh and India.
Sylheti’s decline stems from five main factors: lack of official recognition, persistent mislabelling as a dialect, deliberate propaganda denying its legitimacy, deep-rooted social stigma, and a near total absence of policy or financial support. Children are discouraged from speaking Sylheti in schools and often even at home. In India, Assamese and Bengali dominate education, while in Britain, children of Sylheti heritage are routinely taught Bengali for convenience.
Writers have largely abandoned Sylheti because publishing opportunities are scarce. Most mainstream media use it only for humour or mockery, reinforcing stereotypes rather than celebrating identity. Many Sylheti political and community leaders cannot deliver a single sentence in their own language when speaking publicly. The sense of shame associated with Sylheti has become so deep that speaking Bengali or English is often seen as a mark of education, sophistication and social status, while using Sylheti in public is viewed as provincial.
In Sylhet itself, urbanisation and migration have transformed the region’s demography over the past two decades. In cities, villages and towns, children are taught in school that Bengali is their mother tongue, and families often scold them for using Sylheti at home. Unless urgent action is taken, intergenerational transmission will collapse. Sylheti is already endangered, and without decisive measures to protect and promote it, the language will disappear within living memory.
Myth 6: “Syloti Nagri is just another form of the Bengali script.”
This claim has no scientific or historical basis. The Syloti Nagri script was created to record the unique tones, sounds and rhythm of the Sylheti language, features that cannot be represented within Bengali script. The two systems are entirely different in structure, form, use and phonetic design. Writing Bengali in Syloti Nagri would distort pronunciation and meaning, as the script was never designed for that purpose.
All three scripts, Devanagari, Eastern Nagri and Syloti Nagri, belong to the wider Brahmic family of scripts, but each evolved independently to serve a different linguistic need. Syloti Nagri was created specifically for Sylheti and cannot be used effectively for any other language. It has its own set of vowels, consonants and tone markers that reflect the distinct spoken identity of Sylhet.
Historically, Syloti Nagri existed centuries before the Bengali language was standardised and named by Ishwar Chandra Vidyasagar in the nineteenth century. While Eastern Nagri was adapted to write Bengali and Assamese, Syloti Nagri developed separately as the writing system of the Sylheti people. No historical record or linguistic evidence shows that it originated from, or functioned as, a variant of Bengali script.
To describe Syloti Nagri as another form of Bengali is therefore incorrect and misleading. It is an independent script with its own structure, history and purpose, created by Sylheti speakers for the Sylheti language, and preserved through centuries as a mark of cultural and linguistic identity.
Myth 7: “Syloti Nagri was used only by Muslims.”
This belief is historically false. Although many futhis (religious booklets) were Islamic in content, the script itself predates the arrival of Islam in Sylhet. Hindu Sylhetis also used Syloti Nagri for personal letters, poetry and community records. Long before Shah Jalal’s arrival, the people of Sylhet were already speaking Sylheti, and there is no evidence that Bengali or Assamese was the dominant language of the region.
When Shah Jalal and his companions brought Islam to Sylhet, they preached in Sylheti so that people could understand them. This confirms that Sylheti was already the language of the land. The use of the script across religious communities demonstrates that Syloti Nagri served as a cultural bridge rather than a symbol of any single faith.
The decline of Syloti Nagri was driven by a combination of political, economic and social forces rather than by natural evolution. The main printing press that produced books in this script was destroyed in the nineteenth century, and no government since has offered meaningful support for its revival. Its survival today owes everything to the dedication of the community and to recent digital preservation efforts. Syloti Nagri is older than the standardised Bengali script and belongs equally to all Sylhetis, regardless of religion or geography. To claim otherwise is to deny the shared heritage of an entire nation.
Myth 8: “Sylhetis are Bengali.”
Sylhetis are not ethnically Bengali unless through mixed heritage. The Sylheti identity predates modern Bangladesh and is rooted in its own geography, language and culture. In Sylheti, the word “Bengoli” (ꠛꠦꠋꠉꠟꠤ) traditionally meant “non-Sylheti” or “a person from Bengal”, and it is still used in many villages today. The confusion arises from the careless mixing of nationality and ethnicity. Being Bangladeshi is a matter of citizenship, whereas being Bengali refers to a separate ethnolinguistic group. Sylhetis are a distinct people found across Bangladesh, India and large diaspora communities around the world. If Sylhetis in Bangladesh are called Bengali, what then should we call the millions of Sylhetis living in India or Britain? The same ethnic group cannot have different identities divided by borders.
This misunderstanding has been reinforced by state institutions, education and the media. Schools teach children that to be Bangladeshi is to be Bengali. Television and radio promote Bengali as the only acceptable cultural identity, while Sylheti is often stigmatised as rural or unrefined. Many abroad have inherited this confusion and describe themselves as Bengali for convenience, even though they speak Sylheti at home. Yet Sylhet’s identity runs far deeper than language alone. Its people preserve a unique heritage of customs, festivals and cuisine that existed long before Bengali traditions reached the region. From wedding rituals such as “mas kata” to dishes like “tenga”, Sylheti culture reflects a distinct history and lifestyle that define who its people are. To call all this Bengali is to erase the cultural diversity, heritage, language and identity that make Sylhet truly its own.
The Sylheti people are indigenous to the land of Sylhet. All others arrived later through migration, displacement, trade or refuge. The notion that the people of Sylhet first spoke Bengali, then invented a completely new language and script, and were later reabsorbed into Bengali society defies all logic. The more coherent and historically consistent explanation is that Sylheti has always been the native language of the Sylhet region, later overshadowed by political and cultural dominance.
Sylheti is not a dialect, a curiosity, a regional language, a fragment of Bengali, or a mixture of languages. It is an ancient and living language, though now endangered, with its own structure, script and history. Sylheti represents a language, an ethnicity, a heritage, a history and an identity whose existence is at risk of disappearing due to mislabelling, propaganda and the absence of official recognition. It is deeply ironic that a country which proudly celebrates 21 February as International Mother Language Day continues to fail an entire nation of people by denying official recognition to their own mother tongue. Its story mirrors the struggles of many marginalised languages across the world, suppressed by power yet sustained by people. The evidence for Sylheti’s independence is overwhelming, and the denial of its status is indefensible. To recognise Sylheti is to restore truth, dignity and continuity to a people whose voice has too long been silenced.
