The new grammar, however, does not by itself entail a new language. A recurring factor in the emergence of new languages is the challenge to the existing socio-political order by an emerging social group that seeks a separate cultural, social and political identity and power. The new language is legitimized by creating written literature in it and by codifying its grammar in a book. The written down literature and grammar give linguistic autonomy to the new language. The Indian linguistic heritage accepts such new languages, allows them a cultural space and integrates them into the linguistic net work of the nation.
New languages continue to come about to date, but the process of their appearance is different.
The claim for their linguistic autonomy may or may not arise internally on socio-political grounds from the speech community. Nevertheless, the language planners must give freedom to the community for its latent linguistic consciousness to be codified in grammar and expressed in written literature. This will enrich the linguistic heritage of the nation. This dynamics is a characteristic feature of linguistic plurality in India. The changing socio-cultural net working of languages with stable linguistic plurality has been made possible by various factors.
