Languages of South Asia
South Asia is home to several hundred languages, spanning the countries of Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. It is home to the third most spoken language in the world, Hindi–Urdu; and the sixth most spoken language, Bengali. The languages in the region mostly comprise Indo-Iranic and Dravidian languages, and further members of other language families like Austroasiatic, and Tibeto-Burman languages. English is considered the international lingua franca of the South Asian countries. Geographical distribution 

Geolinguistically, the Indo-Aryan, Dravidian and Munda language groups are predominantly distributed across the Indian subcontinent, hence sometimes collectively known as Indic languages. The subcontinent is also home to a few language isolates, like Burushaski, Kusunda, Nihali, and Vedda. Aerially, the influence of the languages extend beyond the subcontinent into other neighboring Southern Asian as well as East and Southeast Asian regions, and the extended linguistic area is known as Indosphere. More precisely, the sprachbund of Indic languages and other geopolitically-neighboring languages is known as South Asian languages. The Iranian Plateau located west to the subcontinent is home to Iranic languages, beginning with Pashto of Pashtunistan and Balochi of Balochistan in the eastern-side of the plateau. Nuristani languages are spoken in pockets at the northern intersection of the plateau and the subcontinent. Tibeto-Burman languages of the Trans-Himalayan family and Khasi–Palaungic languages of the Austroasiatic family are spoken in and beyond the regions of the Himalayan and Indo-Burman Ranges, predominantly on the Tibetan Plateau and Burma. Andamanese languages are spoken on the Andaman Islands. By country
