The Eighth Schedule to the Constitution of India lists the official languages of the Republic of India. ‘Sindhi’ was not one of the original 14 languages listed in the Eighth Schedule. It was added to the list by the Constitution (Twenty-first Amendment) Act, 1967.
The Eighth Schedule currently lists 22 languages. Amendments have added languages to this list over time, reflecting linguistic diversity and demands for recognition.
Subsequent amendments that added languages to the Eighth Schedule include the 71st Amendment Act, 1992 (adding Konkani, Manipuri, and Nepali) and the 92nd Amendment Act, 2003 (adding Bodo, Dogri, Maithili, and Santhali). The other schedules mentioned deal with different subjects: Fourth Schedule (Rajya Sabha seat allocation), Sixth Schedule (administration of tribal areas in Assam, Meghalaya, Tripura, and Mizoram), and Tenth Schedule (anti-defection law).
