Indo-Aryan languages
Eastern Zone

The Eastern Indo-Aryan languages, also known as Magadhan languages, are spoken throughout the eastern subcontinent, including Odisha and Bihar, alongside other regions surrounding the northwestern Himalayan corridor. Bengali is the seventh most-spoken language in the world, and has a strong literary tradition; the national anthems of India and Bangladesh are written in Bengali. Assamese and Odia are the official languages of Assam and Odisha, respectively. The Eastern Indo-Aryan languages descend from Magadhan Apabhraṃśa and ultimately from Magadhi Prakrit. Eastern Indo-Aryan languages display many morphosyntactic features similar to those of Munda languages, while western Indo-Aryan languages do not. It is suggested that "proto-Munda" languages may have once dominated the eastern Indo-Gangetic Plain, and were then absorbed by Indo-Aryan languages at an early date as Indo-Aryan spread east.
