<P0-S0> The official and de facto national language of Bangladesh is Modern Standard Bengali (Literary Bangla). <P0-S1>  It serves as the "lingua franca" of the nation, with 98% of Bangladeshis fluent in Standard Bengali or Bengali dialects as their first language. <P0-S2>  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. <P0-S3>  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> <P1-S0> Bengali ( ), also known by its endonym Bangla ( ; বাংলা ] ), is an Indo-Aryan language spoken in the Indian Subcontinent. <P1-S1>  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. <P1-S2>  It is also one of the 22 scheduled languages of India. <P1-S3>  With 205 million speakers, Bengali is the seventh most spoken native language in the world by population. <P1-S4>  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. <P1-S5>  Dominant in the last group was Persian, which was also the source of some grammatical forms. <P1-S6>  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. <P1-S7>  Today, Bengali is the primary language spoken in Bangladesh and the second most widely spoken language in India. <SEP> <P2-S0> Jaydeep Sarangi (Bengali: জয়দীপ ষড়ঙ্গী, born 11 December 1973) is a bilingual writer, poet, critic, academician, editor, interviewer, translator and author of a number of significant publications on Australian literature, Indian writing in English, postcolonial studies and Dalit literary movement in India. <P2-S1>  He is a senior faculty in English at Jogesh Chandra Chaudhuri College (University of Calcutta), Kolkata. <P2-S2>  He has also been acting as a vice-president of GIEWEC, a registered literary forum in India, and as an executive member of PEN, Kolkata. <P2-S3>  He has travelled across the globe as the resource person and writer in several universities and has endeavored to epitomize Indian writings at the threshold of World Literature. <SEP> <P3-S0>  He is Associate Professor of Liberal Studies/Interdisciplinary Studies at Grand Valley State University in Michigan, and Vice-President of the Global Center for Advanced Studies (GCAS) and Honorary GCAS Professor of English, World Literature, and Interdisciplinary Studies. <P3-S1>  He taught English, World Literature, Ethnic Studies, and Cultural Studies at Washington State University, Bowling Green State University, and Oklahoma State University; while, in Bangladesh, he taught English at Jahangirnagar University and North South University. <P3-S2>  He also worked as Scholar-in-Residence at the University of Liberal Arts Bangladesh. <P3-S3> Azfar Hussain (Bengali: আজফার হোসেন ) is a Bangladeshi theorist, critic, academic, bilingual writer, poet, translator, and activist. <P3-S4>  He is an advisory editor of "Rhizomes: Cultural Studies in Emerging Knowledge". <P3-S5>  He is also an editorial board member of the Bengali journals "Natun Diganta" and "Sarbajonakotha".
