Bengali–Assamese script

The Bengali–Assamese script, sometimes also known as Eastern Nagri, is an eastern Brahmic script, primarily used today for the Bengali and Assamese language spoken in eastern South Asia. It evolved from Gaudi script, also the common ancestor of the Odia and Tirhuta scripts. It is commonly referred to as the Bengali script by Bengalis and the Assamese script by the Assamese, while in academic discourse it is sometimes called Eastern-Nāgarī. The script was traditionally called Gauḍa (not to be confused with the name Gaudi script – which was given later) as seen in the catalogue of books at the Radha-Damodara Mandir maintained by Jiva Goswami during the time of Akbar. Bengali is the official and national language of Bangladesh and three of the 22 official languages of the Indian Republic—Bengali, Assamese, and Meitei—commonly use this script in writing;

Besides, Bengali and Assamese languages, it is also used to write Bishnupriya Manipuri, Meitei, Chakma, Santali and numerous other smaller languages spoken in eastern South Asia. Historically, it was used to write various Old and Middle Indo-Aryan languages, and, like many other Brahmic scripts, is still used for writing Sanskrit. Other languages, such as Bodo, Karbi, Maithili and Mising were once written in this script. The two major alphabets in this script – Assamese and Bengali – are virtually identical, except for two characters — Assamese differs from Bengali in one letter for the /r/ sound, and an extra letter for the /w/ or /v/ sound.
