Azfar Hussain (Bengali: আজফার হোসেন ) is a Bangladeshi theorist, critic, academic, bilingual writer, poet, translator, and activist.  He is also an editorial board member of the Bengali journals "Natun Diganta" and "Sarbajonakotha". <SEP> The official and de facto national language of Bangladesh is Modern Standard Bengali (Literary Bangla).  It serves as the "lingua franca" of the nation, with 98% of Bangladeshis fluent in Standard Bengali or Bengali dialects as their first language.  However 16% of the population speak the languages of Sylheti and Chittagonian which the Bangladeshi Government counts as being dialects of Bengali but in reality only 82% of the population speak true standard Bengali.  English, having no official status, is prevalent across government, law, business, media and education, and can be regarded as the de facto co-official language of Bangladesh (see Bangladeshi English). <SEP> Bengali ( ), also known by its endonym Bangla ( ; বাংলা ] ), is an Indo-Aryan language spoken in the Indian Subcontinent.  It is also one of the 22 scheduled languages of India.  With 205 million speakers, Bengali is the seventh most spoken native language in the world by population.  Dictionaries from the early 20th century attributed slightly more than half of the Bengali vocabulary to native words (i.e., naturally modified Sanskrit words, corrupted forms of Sanskrit words, and loanwords from non-Indo-European languages), about 30 percent to unmodified Sanskrit words, and the remainder to foreign words.  Dominant in the last group was Persian, which was also the source of some grammatical forms.  More recent studies suggest that the use of native and foreign words has been increasing, mainly because of the preference of Bengali speakers for the colloquial style.  Today, Bengali is the primary language spoken in Bangladesh and the second most widely spoken language in India.  It is the national and official language of the People's Republic of Bangladesh, and the official language of some eastern and north-eastern states of the Republic of India, including West Bengal, Tripura, Assam (Barak Valley) and Andaman and Nicobar Islands.
