[a] The Semitic origin of the Brahmic scripts is not universally agreed upon.

The Assamese script[1] is a writing system of the Assamese language. It used to be the script of choice in the Brahmaputra valley for Sanskrit as well as other languages such as Bodo (now Devanagari), Khasi (now Roman), Mising (now Roman) etc. It evolved from Kamarupi script. The current form of the script has seen continuous development from the 5th-century Umachal/Nagajari-Khanikargaon rock inscriptions written in an eastern variety of the Gupta script, adopting significant traits from the Siddhaṃ script in the 7th century. By the 17th century three styles of Assamese script could be identified (baminiya, kaitheli and garhgaya)[2] that converged to the standard script following typesetting required for printing. The present standard is identical to the Bengali alphabet except for two letters, র (ro)and ব(vo).

The Buranjis were written during the Ahom dynasty in the Assamese language using the Assamese alphabet. In the 14th century Madhava Kandali used Assamese script to compose the famous Saptakanda Ramayana, which is the first translation of Ramayana in a regional language after Valmiki's Ramayana in Sanskrit. Later, Sankardev used it in the 15th and 16th centuries to compose his oeuvre in Assamese and Brajavali dialect, the literary language of the bhakti poems (borgeets) and dramas.

The Ahom king Supangmung (1663–1670) was the first ruler who started issuing Assamese coins for his kingdom. Some similar scripts with minor differences are used to write Maithili, Bengali, Meithei and Sylheti.


Kanai-boroxiboa rock inscription, 1207 CE, shows proto-Assamese script

The Umachal rock inscription of the 5th century evidences the first use of a script in the region. The script was very similar to the one used in Samudragupta's Allahabad Pillar inscription. Rock and copper plate inscriptions from then onwards, and Xaansi bark manuscripts right up to the 18th–19th centuries show a steady development of the Assamese script. The script could be said to develop proto-Assamese shapes by the 13th century. In the 18th and 19th century, the Assamese script could be divided into three varieties: Kaitheli (also called Lakhari in Kamrup region, used by non-Brahmins), Bamuniya (used by Brahmins, for Sanskrit) and Garhgaya (used by state officials of the Ahom kingdom)—among which the Kaitheli style was the most popular, with medieval books (like the Hastir-vidyrnava) and sattras using this style.[3] In the early part of the 19th century, Atmaram Sarmah designed the first Assamese script for printing in Serampore, and the Bengali and Assamese lithography converged to the present standard that is used today.

Assamese symbols[edit]


The script presently has a total of 11 vowel letters, used to represent the eight main vowel sounds of Assamese, along with a number of vowel diphthongs. All of these are used in both Assamese and Bengali, the two main languages using the script. Some of the vowel letters have different sounds depending on the word, and a number of vowel distinctions preserved in the writing system are not pronounced as such in modern spoken Assamese or Bengali. For example, the Assamese script has two symbols for the vowel sound [i] and two symbols for the vowel sound [u]. This redundancy stems from the time when this script was used to write Sanskrit, a language that had a short [i] and a long [iː], and a short [u] and a long [uː]. These letters are preserved in the Assamese script with their traditional names of hôrswô i (lit. 'short i') and dirghô i (lit. 'long i'), etc., despite the fact that they are no longer pronounced differently in ordinary speech.

Vowel signs can be used in conjunction with consonants to modify the pronunciation of the consonant (here exemplified by , kô). When no vowel is written, the vowel (ô or o) is often assumed. To specifically denote the absence of a vowel, () may be written underneath the consonant.

The text says: "Sri Sri Môt Xiwô Xinghô Môharaza". The "" is used as "" in this 18th-century manuscript, just as in modern Mithilakshar.

The names of the consonant letters in Assamese are typically just the consonant's main pronunciation plus the inherent vowel ô. Since the inherent vowel is assumed and not written, most letters' names look identical to the letter itself (e.g. the name of the letter is itself ghô). Some letters that have lost their distinctive pronunciation in Modern Assamese are called by a more elaborate name. For example, since the consonant phoneme /n/ can be written , , or (depending on the spelling of the particular word), these letters are not simply called no; instead, they are called dontiya no ("dental n"), murdhoinno no ("retroflex n"), and nio. Similarly, the phoneme /x/ can be written as taloibbo xo ("palatal x"), murdhoinno xo ("retroflex x"), or dontia xo ("dental x"), the phoneme /s/ can be written using prothom sô ("first s") or ditio so ("second s"), and the phoneme /z/ can be written using borgia zo ("row z" = "the z included in the five rows of stop consonants") or ontostho zo ("z situated between" = "the z that comes between the five rows of stop consonants and the row of sibilants"), depending on the standard spelling of the particular word.

Consonant clusters[edit]

A few of Asamiya Consonant Conjuncts.
Asamiya vowel diacritics.

Assamese or Asamiya consonant clusters include thirty three pure consonant letters in Assamese alphabet and each letter represents a single sound with an inherent vowel, the short vowel /a /.

The first twenty-five consonants letters are called ‘sporxo borno’. These ‘sporxo bornos’ are again divided into five ‘borgos’. Therefore, these twenty-five letters are also called ‘borgio borno’.

The Assamese consonants are typically just the consonant's main pronunciation plus the inherent vowel o. The inherent vowel is assumed and not written, thus, names of most letters look identical to the letter itself (e.g. the name of the letter ঘ is itself ঘ gho).

Some letters have lost their distinctive pronunciation in modern Assamese are called by a more elaborate name. For example, since the consonant phoneme /n/ can be written ন, ণ, or ঞ (depending on the spelling of the particular word), these letters are not simply called no; instead, they are called ন dointo no ("dental n"), ণ murdhoinno no ("cerebral n"), and ঞ nio.

Similarly, the phoneme /x/ can be written as শ taloibbo xo ("palatal x"), ষ murdh9inno xo ("cerebral x"), or স dointo xo ("dental x"), the phoneme/s/ can be written using চ prothom so ("first s") or ছ ditio so ("second s"), and the phoneme /z/ can be written using জ borgio zo ("row z" = "the z included in the five rows of stop consonants") or য ontostho zo ("z situated between" = "the z that comes between the five rows of stop consonants and the row of sibilants"), depending on the standard spelling of the particular word.

  • The letters (talôibbya xô), (murdhôinnya xô), (dôntiya xô) and (hô) are called “usma barna
  • The letters (za), ৰ (ra), ল (la) and (wa) are called “ôntôsthô barna
  • The letters ড় (daré ṛa) and ঢ় (dharé ṛha) are phonetically similar to /ra /
  • The letter (ôntôsthô zô) is articulated like “'ôntôsthô yô'” in the word medial and final position. To denote the “ ôntôsthô ẏô” the letter য় (ôntôsthô ẏô) is used in Assamese
  • (khanda ṯ) means the consonant letter Tö (dôntiya ta) without the inherent vowel


To write a consonant without the inherent vowel the halant sign is used below the base glyph. In Assamese this sign is called ‘haxanta’. (্)

Consonant Conjuncts[edit]

In Assamese, the combination of three consonants is possible without their intervening vowels. There are about 122 conjunct letters. A few conjunct letters are given below:


Anuxôr ( ং ) indicates a nasal consonant sound (velar). When an anuxar comes before a consonant belonging to any of the 5 bargas, it represents the nasal consonant belonging to that barga.


Chandrabindu ( ঁ ) denotes nasalization of the vowel that is attached to it .


Bixargô ( ঃ ) represents a sound similar to /h /.

Consonant clusters according to Goswami[edit]

According to Dr. G. C. Goswami the number of two-phoneme clusters is 143 symbolised by 174 conjunct letters. Three phoneme clusters are 21 in number, which are written by 27 conjunct clusters. A few of them are given hereafter as examples:
