Indian language:

The languages of India belong to several major linguistic families, the two largest being the Indo-European languages---Indo-Aryan (spoken by 70% Indians) and the Dravidian languages, (spoken by 22% Indians). Other languages spoken in India come mainly from the Austro-Asiatic and Tibeto-Burman linguistic families, in addition to a few language isolates.[1]
Individual mother tongues in India number several hundred[2]; the 1961 census recognized 1,652[3] (SIL Ethnologue lists 415). According to Census of India of 2001, 29 languages are spoken by more than a million native speakers, 122 by more than 10,000. Three millennia of language contact has led to significant mutual influence among the four language families in India and South Asia. Two contact languages have played an important role in the history of India: Persian and English.[4]
The languages of India may be grouped by major language families. The largest of these in terms of speakers is the Indo-European family, predominantly represented in its Indo-Aryan branch (accounting for some 700 million speakers), but also including minority languages such as Persian, Portuguese or French, and English as lingua franca. The second largest is the Dravidian family, accounting for some 200 million speakers. Minor linguistic families include the Austro-Asiatic and Tibeto-Burman families (with some 10 and 6 million speakers, respectively). Kashmiri, considered a Dardic language, has some 4.6 million speakers in India. There is also a language isolate, the Nihali language.
