For example, the Assamese word for “rice” is “bhaat”, which is a loanword from the Bodo language. Another way that tribal languages have influenced Assamese dialects is through the introduction of unique grammatical features. For example, the Assamese verb system is influenced by the verb systems of the Bodo and Garo languages. Finally, tribal languages have also influenced Assamese dialects through regional variations in pronunciation. For example, the pronunciation of the Assamese letter “o” varies from region to region, depending on the influence of the local tribal languages.
