Languages with official status in India
The Constitution of India designates the official language of the Government of India as Hindi written in the Devanagari script, as well as English. There is no national language as declared by the Constitution of India. Hindi is used for official purposes such as parliamentary proceedings, judiciary, communications between the Central Government and a State Government. States within India have the liberty and powers to specify their own official language(s) through legislation and therefore there are 22 officially recognized languages in India of which Hindi is the most used. The number of native Hindi speakers is about 25% of the total Indian population; however, including dialects of Hindi termed as Hindi languages, the total is around 44% of Indians, mostly accounted from the states falling under the Hindi belt. Other Indian languages are each spoken by around 10% or less of the population.
Bharati Braille
Bharati braille ( ), or Bharatiya Braille (Hindi: "" "Indian braille"), is a largely unified braille script for writing the languages of India. When India gained independence, eleven braille scripts were in use, in different parts of the country and for different languages. By 1951 a single national standard had been settled on, Bharati braille, which has since been adopted by Sri Lanka, Nepal, and Bangladesh. There are slight differences in the orthographies for Nepali in India and Nepal, and for Tamil in India and Sri Lanka. There are significant differences in Bengali Braille between India and Bangladesh, with several letters differing. Pakistan has not adopted Bharati braille, so the Urdu Braille of Pakistan is an entirely different alphabet than the Urdu Braille of India, with their commonalities largely due to their common inheritance from English or International Braille. Sinhalese Braille largely conforms to other Bharati, but differs significantly toward the end of the alphabet, and is covered in its own article.
