Jana Gana Mana
This category is for dialects, mostly restricted to certain communities instead of a region, as well as closely related languages. Dobhashi was a highly Persianised dialect originating during the Bengal Sultanate period. The sadhu bhasha was a historical Sanskritised register of Bengali and Christian Bengali was a Europeanised dialect; both of which originated during the colonial period. Examples of heavily Sanskritised Bengali include the Jana Gana Mana.
