The Southern Indian languages are from the Dravidian family. The Dravidian languages are indigenous to the Indian subcontinent. Proto-Dravidian languages were spoken in India in the 4th millennium BCE and started disintegrating into various branches around 3rd millennium BCE.
The Dravidian languages are classified in four groups: North, Central (Kolami–Parji), South-Central (Telugu–Kui), and South Dravidian (Tamil-Kannada).
The Northern Indian languages from the Indo-Aryan branch of the Indo-European family evolved from Old Indo-Aryan by way of the Middle Indo-Aryan Prakrit languages and Apabhraṃśa of the Middle Ages. The Indo-Aryan languages developed and emerged in three stages — Old Indo-Aryan (1500 BCE to 600 BCE), Middle Indo-Aryan stage (600 BCE and 1000 CE), and New Indo-Aryan (between 1000 CE and 1300 CE). The modern north Indian Indo-Aryan languages all evolved into distinct, recognisable languages in the New Indo-Aryan Age.
In the Northeast India, among the Sino-Tibetan languages, Meitei language (officially known as Manipuri language) was the court language of the Manipur Kingdom (Meitei: Meeteileipak). It was honoured before and during the darbar sessions before Manipur was merged into the Dominion of the Indian Republic. Its history of existence spans from 1500 to 2000 years according to most eminent scholars including Padma Vibhushan awardee Suniti Kumar Chatterji.
Even according to the “Manipur State Constitution Act, 1947” of the once independent Manipur, Manipuri and English were made the court languages of the kingdom (before merging into Indian Republic)
