Sylheti (native name সিলটী Silôţi; Bengali name সিলেটী Sileţi) is the language of Sylhet proper, the north-eastern region of Bangladesh and southern districts of Assam around Silchar. It is also spoken by a significant population in the other north-eastern states of India and amongst the large expatriate communities in the UK, USA, Canada and the Middle East. It is similar enough to Bengali (Bangla) to be considered a dialect of that language, but at times it is probably better seen as a separate language. Given that Sylhet was part of the ancient kingdom of Kamarupa,[1] the language has many common features with Assamese, including the existence of a larger set of fricatives than other East Indic languages. According to Grierson,[2] "The inflections also differ from those of regular Bengali, and in one or two instances assimilate to those of Assamese". Indeed it was formerly written in its own script, Sylheti Nagari, similar in style to Kaithi but with differences, though nowadays it is almost invariably written in Bengali script. (source Wikipedia)
