Sylheti Nagri

This structure, namely "Nagri Chattar" (Nagri Square), built near Surma river in the city of Sylhet, Bangladesh consists of characters of this script.

According to Qadir (1999) and Professor Clifford Wright, the script descends from Kaithi script, a script predominantly used in Bihar.[4]

The specific origin of the script is debated. Though most popular in Sylhet, the script was historically also used in Greater Mymensingh, Tripura, Meghalaya and Assam.[12] One hypothesis is that the Muslims of Sylhet were the ones to invent it for the purpose of mass Islamic education.[13] This is thought to have taken place during the 15th-century, when the Bengali Hindus led by Krishna Chaitanya, started a Sanskrit and Vaishnavist reawakening movement.[14] On the other hand, according to Ahmad Hasan Dani it was the Afghans living in Sylhet during the 15th-century Afghan rule who invented the script, since some of Sylheti Nagri's letters resemble the symbols on Afghan coins, and there were a large number of Afghans living in Sylhet at that time.[6] Another theory dates the script's origin as late as the seventeenth—eighteenth century; claiming that it was invented to facilitate the Muslim sepoys coming from the joint state of Bihar and other immigrant Muslims.[15]

Though almost solely used by Muslims, there are other theories which point the script's origins to Buddhists and Hindus who later converted to Islam. Some say that the script was invented by immigrant Bhikkhus (originally Buddhist in faith) from neighbouring countries such as Nepal.[15]

The simplistic nature of the script inspired a lot of poets, though the bulk of Sylheti Nagri literature was born in the late 19th century. Abdul Karim, a munshi who was studying and completing his education in London, spent several years in the English capital to learn the printing trade. After returning home in circa 1869, he designed a woodblock type for the script and founded the Islamia Printing Press in Bandar Bazar, Sylhet. Padmanath Bhattacharjee Vidyabinod, who wrote the first scholarly article on the script, is of the opinion that Abdul Karim's standardisation marks the start of the script's reawakening (nobojonmo) period.[16] Prior to Abdul Karim's intervention, not much is known about the popularity and usage of the script.[17] The manuscripts were of prosaic quality,[15] but poetry was also abundant.

Other Sylheti Nagri presses were established in Sylhet, Sunamganj, Shillong and Kolkata. Some include the Sarada Printing and Publishing in Naiyorpul, Sylhet; and Calcutta's General Printing Works in 16 Gardner Lane, Taltala as well as the Hamidi Press in Sealdah.[11] It has been asserted from scholarly writings that the script was used as far as Bankura, Barisal, Chittagong and Noakhali.[6] From the description of Shreepadmanath Debsharma:

The script in prior times was used in Srihatta. With the advent of printing the script now has spread to all of the Srihatta district, Kachar, Tripura, Noakhali, Chittagong, Mymensingh and to Dhaka, that is, to the Muslims of the entire region of Bengal east of Padma.[5]

The script is thought to have spread to Chittagong and Barisal via river.

Although the script vastly extended across Bengal, its use "was restricted to a certain class of Muslims", in particular the Muslim women.[18]

The language transcribed of the literature was written in a particular Dobhashi (Late Middle Bengali) style, with its phonology (and some vocabulary) being strongly influenced by the regional vernacular, Sylheti.[1] Like the rest of Muslim Bengal, Bengali Muslim poetry was written in a colloquial dialect of Bengali which came to be known as Dobhashi. Manuscripts have been found of works such as Rag Namah by Fazil Nasim Muhammad, Shonabhaner Puthi by Abdul Karim and the earliest known work Talib Husan (1549) by Ghulam Husan.[12]

The Munshi Sadeq Ali is considered to have been the greatest and most popular writer of the script. The script has also been used in the daily lives of the inhabitants of Sylhet apart from using in religious literature. Letters, receipts, and even official records has been written using this script. Apart from renowned literary works such as Halat-un-Nabi, Jongonama, Mahabbatnama or Noor Noshihot, it has been used to write medicine and magical manuscripts, as well as Poems of the Second World War.

The script, never having been a part of any formal education, reached the common people with seeming ease.[6] Although it was hardly used in comparison to the Bengali script, it was common for lower-class Sylheti Muslims to sign their names in this script.[7] Many Sylheti Nagri presses fell out of use during the Bangladeshi Liberation War and Indo-Pakistani War of 1971, including Islamia Press in Sylhet town which was destroyed by a fire.^{[citation needed]}

Many Sylheti Nagri presses fell out of use during the Bangladeshi Liberation War and Indo-Pakistani War of 1971, including Islamia Press in Sylhet town which was destroyed by a fire. It gradually became very unpopular the script is used mainly by linguists and academics.[19][20] Research on the script multiplied to its greatest extent in post-colonial Pakistan and Bangladesh.[18] In the 19th century, Munshi Ashraf Hussain, a researcher of Bengali folk literature, contributed immensely to Sylheti Nagri research.[21] In the 2010s, Md. Salik Ahmed, Md. Nizam Uddin and Md. Mamunur Rasid translated the last juz' of the Qur'an into the Sylheti language for the first time using both the Eastern Nagari and Sylheti Nagri scripts.[22]

The widely accepted number of vowels is 5, although some texts show additional vowels. For example, the diphthong ôi has sometimes been regarded as an additional vowel. The vowels don't follow the sequence of Bengali alphabet. The vowels also have their own respective diacritics known as "horkot".

• "ꠅ" /ɔ/ sounds as the default inherent vowel for the entire script.
• When a vowel sound occurs syllable-initially or when it follows another vowel, it is written using a distinct letter. When a vowel sound follows a consonant (or a consonant cluster), it is written with a diacritic which, depending on the vowel, can appear above, below, before or after the consonant. These vowel marks cannot appear without a consonant and are called horkot.
• An exception to the above system is the vowel /ɔ/, which has no vowel mark but is considered inherent in every consonant letter. To denote the absence of the inherent vowel [ɔ] following a consonant, a diacritic called the oshonto (꠆) may be written underneath the consonant.
• Although there is only one diphthong in the inventory of the script: "ꠂ" oi /oi/, its phonetic system has, in fact, many diphthongs. Most diphthongs are represented by juxtaposing the graphemes of their forming vowels, as in ꠇꠦꠃ /xeu/.

There are 27 consonants. The names of the letters are typically just the consonant sound with the inherent vowel ꠅ /ɔ/. Since the inherent vowel is assumed and not written, most letters' names look identical to the letter itself, i.e. the name of the letter ꠊ is ghô.

There is a difference between the pronunciation of ꠞ rô and ꠠ ṛo. Although in ordinary speech these are pronounced the same as /ɾɔ/.

In 1997, Sue Lloyd-Williams of STAR produced the first computer font for script. The New Surma is a proprietary font. Noto fonts provides an open source font for the script. Syloti Nagri was added to the Unicode Standard in March 2005 with the release of version 4.1, and is available on Apple devices.[23] Other fonts include Mukter Ahmed's Fonty 18.ttf, developed from manuscripts to include traditional Sylheti numbers. As a routine project of the Metropolitan University, Sylhet, Sabbir Ahmed Shawon and Muhammad Nurul Islam (under the name CapsuleStudio) developed and launched the Syloti Nagri Keyboard, also for Google Play, on 9 December 2017.[24] Different keyboards and fonts are available now:

• Syloti Nagri Notes, by the UK-based Sureware Ltd on Google Play.[25]
• Multiling O Keyboard, with additional app Sylheti Keyboard plugin by Honso, on Google Play.[26]
• Google's GBoard has also made Sylheti (Syloti Nagri) available as an input from April 2019.[27]
