Nagamese and Assamese: how close are they really?
The short answer: same word stock, different machine. An Assamese speaker meeting Nagamese for the first time recognises most of the words and misses a good deal of the meaning.
What the relationship actually is
Nagamese is Assamese-lexified. That is a precise term: it means the bulk of its vocabulary derives from Assamese, while its grammatical system developed separately, under the conditions that produce a creole. It is not a dialect of Assamese, and calling it "broken Assamese" gets the relationship backwards.
The comparison linguists reach for is Haitian Creole and French. Almost all the words come from French; the grammar is not French grammar; and a Parisian cannot follow a conversation in Port-au-Prince. Nagamese and Assamese sit in a similar relation, with the important difference that Nagamese and Assamese speakers are in continuous contact, so the two keep influencing each other.
Where they diverge
1. Verb agreement is gone
This is the big one. Assamese conjugates verbs for person and honorific level. Nagamese does not conjugate at all. One form serves every subject:
For a learner this is a gift. For an Assamese speaker it is the most audible marker that they are hearing Nagamese and not Assamese.
2. The case system has collapsed into a handful of particles
Assamese has a richer inflectional apparatus. Nagamese runs on a small, invariable set: laga for possession, te for location, para for origin and means, logote for accompaniment, nimite for purpose. None of them change form.
3. Different negation strategy
Nagamese has settled on the two-way split described in the grammar guide: post-verbal nai for events, prefixed na- for knowledge and ability. The distribution is its own.
4. A large and growing non-Assamese layer
Nagamese borrows freely and constantly — from English (student, phone, laptop, help, tired), from Hindi (lekin, karon, rasta), and from Naga languages. A modern Nagamese sentence like Morom para apni laga laptop restart koribi is entirely idiomatic and would be odd in Assamese.
5. Phonology has simplified
Nagamese has a smaller sound inventory than Assamese, and spelling reflects pronunciation more directly. There is also no orthographic standard, since Nagamese is written in Roman script while Assamese uses the Assamese script — which alone makes the two look completely unlike each other on the page.
So can they understand each other?
Partially, asymmetrically, and unreliably. An Assamese speaker hearing Nagamese picks up a great deal of vocabulary and can often follow the gist of a simple, concrete exchange. Extended conversation, anything abstract, and anything with a lot of English or Hindi borrowing all fall apart.
Going the other way is harder. Assamese verb morphology and its fuller case system are simply not present in Nagamese for a speaker to map onto, so a Nagamese speaker with no exposure to Assamese has less to work with.
