Dobhashi (Bengali: দোভাষী, romanized: Dobhāṣī, lit. 'bilingual') is a neologism used to refer to a historical register of the Bengali language which borrowed extensively, in all aspects, from Arabic and Persian. It became the most customary form for composing puthi poetry predominantly using the traditional Bengali alphabet. However, Dobhashi literature has also been produced in the Sylhet Nagri script, as well as in the modified Arabic scripts of Chittagong and Nadia. The standardisation of the modern Bengali language during the colonial period, eventually led to its decline.
