The Eighth Schedule to the Constitution of India lists the official languages of the Republic of India. At the time when the Constitution was enacted, inclusion in this list meant that the language was entitled to representation on the Official Languages Commission, and that the language would be one of the bases that would be drawn upon to enrich Hindi, the official language of the Union. The list has since, however, acquired further significance. The Government of India is now under an obligation to take measures for the development of these languages, such that they grow rapidly in richness and become effective means of communicating modern knowledge. Of the 22 languages, 14 were initially included in the Constitution. Subsequently, Sindhi was added in 1967 by 2 lst constitutional amendment act; Konkani, Manipuri and Nepali were added in 1992 by 71 st Constitutional Amendment Act; and Bodo, Dogri, Maithili and Santali were added in 2003 by 92 nd Constitutional Amendment Act.
