Sylheti is the language spoken by 95% of Bangladeshis living in the U.K. This language has been described as being distinct from Bengali in terms of phonology and morphology and shares 80% of its vocabulary with Bengali, the rest being quite distinctive. Standard Bengali
can be perceived as being so different from Sylheti that it has been mistaken as "Pakistani". In turn, speakers of other Bengali dialects can find Sylheti "hardly intelligible".
The writing system for Sylheti is called Sylheti Nagri, last taught in schools in Sylhet more than 50 years ago, although a number of English transliteration schemes are also often used to represent the language.
