Hindi is not our National Language and Hockey is not our National Game. Why?

The Constitution of India does not assign National Language status on Hindi or any other Indian languages. Hindi and English have been declared the official languages Under Article 343, meaning, Parliamentary business, according to the Constitution, may be conducted in either Hindi or English.

The states, however, have the liberty and powers to specify their own official language or languages through legislation. There are 22 officially recognised languages in India. Nearly 60 percent of Indian citizens do not speak Hindi. Hindi is not the mother tongue of the majority of Indians.


Most of the Indians believe that hockey is India’s national sport. But India has no national game. From 1928 to 1956, the Indian hockey team won six straight Olympic gold medals, while winning 24 consecutive matches. We assume hockey as our national game. The main reason is the great success story of Indian hockey. However a recent RTI clarified the issue that Hockey is not the national sport of India.
