Assamese

Closely related but distinct. Both are Eastern Indo-Aryan and share the Bengali-Assamese script (with two letter shape differences specific to Assamese — ৰ for 'r' and ৱ for 'w'). Their grammar is broadly similar. But pronunciation diverges substantially: Assamese has merged sibilants into a velar fricative, has different vowel patterns, and has its own vocabulary layers. Speakers of one need study to fully understand the other.

Across the Brahmaputra valley in the Indian state of Assam — Guwahati, Dibrugarh, Jorhat, Tezpur, and surrounding regions. Assamese is also spoken by minority communities in adjacent Indian states, including parts of Arunachal Pradesh, Nagaland, and Meghalaya. The Assamese diaspora extends to the Gulf, the United States, and the United Kingdom.

Assamese has merged the historical Sanskrit s and sh sounds into a velar fricative — written with letters that historically represented sibilants but now pronounced as a sound similar to the Spanish 'j' or German 'ch'. The same letter combinations that produce 's' or 'sh' in Bengali or Hindi produce a back-of-throat fricative in Assamese, which can throw learners coming from related languages.

No. Like Bengali and Odia, Assamese has lost the gender system that Hindi and Marathi preserve. Verbs and adjectives don't agree with nouns by gender. Assamese does, however, distinguish honorific levels in pronouns and verb forms, with three levels marking different degrees of social respect.

Substantial. Continuous Assamese literature stretches back to the 13th and 14th centuries, with the Charyapada and the Buranji historical chronicles among the earliest surviving works. The 16th-century Vaishnava revival under Sankardeva produced extensive devotional Assamese literature. Modern Assamese has a strong tradition in fiction, poetry, and academic writing.
