According to Wikipedia, Hindi is the official language of India and English is used for official purposes. States can also designate their own official languages. All 28 states and eight union territories have done so.
Just as Latin evolved into French, Italian and Spanish (among other languages), Sanskrit (san) is the parent language of Hindi and many other languages in India. Because of this evolution, Latin and Sanskrit are no longer spoken as native languages and are considered dead languages—or quasi-dead, anyway. Latin continues to be used by the Vatican and as a language of study. In addition to its revered status, Sanskrit continues as a native language by just under 3000 people according to the Ethnologue. Also, nearly 200,000 speakers are listed in the Ethnologue as using Sanskrit as a second language (L2). Moreover, Sanskrit has a strong revitalization movement and nearly 50,000 speakers of Sanskrit were reported in the 1991 census, an indication that there may soon be native speakers if there are not any already.
Sanskrit is an official language in Uttarakhand and the government of India is also obliged to promote Sanskrit as per the Eighth Schedule to the Constitution.
