Greater Chittagong in the context of "Chittagonian language"

Chittagonian (চাটগাঁইয়া saṭgãia or চিটাইঙ্গা siṭaiṅga) or Chittagonian Bengali is an Indo-Aryan language spoken in parts of the Greater Chittagong in Bangladesh. Chittagonian is not inherently intelligible to other varieties of Bengali, although it is considered by some as a nonstandard Bengali dialect. Chittagonian is also considered to be a separate language by some linguists. While Chittagonian is linguistically distinct, its speakers identify with Bengali culture and the Standard Bengali language. It is broadly mutually intelligible with the Rohingya language and with a lesser extent to Noakhali. It is estimated (2006) that Chittagonian has 13 million speakers, principally in Bangladesh.
