Dobhashi (Bengali: দোভাষী, romanized: Dobhaśi, lit. 'bilingual'), is a neologism used to refer to a register which had the Middle Bengali language as its dialectal basis but was shifted to a highly Persianised format. Traditionally, it was the most customary form of writing in Bengali prior to the language's reformation during the colonial period. This style evolved in not only the Eastern Nagari script, but also in Sylheti Nagri as well as the modified Arabic script used in Greater Chittagong, West Bengal and Arakan. The register has had a major influence to the modern Bengali dialects of Eastern and Southeastern Bengal, such as Chittagonian, Noakhailla, Rohingya, Sylheti among others.
