Languages of Bangladesh
The lowlands of Bangladesh form the larger, central and eastern half of the ethno-linguistic region of Bengal and the Bengali language is spoken by the majority of the country's inhabitants. There are also some Eastern Indic language varieties, which are variously classified either as dialects of Bengali or separate but closely related languages. They can be thought of forming a dialect continuum.
