The People?s Linguistic Survey of India provides an overview of the extant and dying languages of India, as perceived by their speakers. It is the outcome of a nationwide survey of languages that has been documented by linguists, writers, social activists, and members of different speech communities. Critically, it encapsulates the world view of the speakers of the languages. West Bengal is unique in terms of linguistic diversity, as the languages spoken in this state belong to four distinct language families?Austro-Asiatic, Dravidian, Indo-European, and Tibeto-Burman. The state?s geographical location and its proximity to the neighbouring states of Odisha, Jharkhand, Bihar, Sikkim and Assam, as well as the neighbouring countries of Bangladesh, Nepal and Bhutan, have further enriched this vast linguistic diversity.
