Bengali ( ), also known by its endonym Bangla ( ; বাংলা ] ), is an Indo-Aryan language spoken in the Indian Subcontinent.
 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.
 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.
