 It is closely related to Kaithi and has some Devanagari, Eastern Nagari and Arabic influences.Literature in the Sylheti Nagri script was mostly common amongst lower class Muslims that lived towards the east of the Sylhet region and has historically been mostly limited to writing puthis and signatures, having no presence in formal documentations.Although in recent times it has lost much ground to the Bengali script, Sylheti Nagri is supposedly beginning to be reintroduced.
