📝 Short Notes: Eighth Schedule and Amendment of Languages

• Eighth Schedule Overview: The Eighth Schedule of the Constitution contains the list of official languages recognized by India. Originally, it included 14 languages when the Constitution came into force in 1950. These languages enjoy constitutional recognition, government support for development, and can be used in parliamentary proceedings and competitive examinations.
• 21st Amendment Act, 1967: This was the first amendment to the Eighth Schedule, adding Sindhi as the 15th language to recognize the linguistic identity of the Sindhi-speaking community displaced during partition.
• 71st Amendment Act, 1992: Added three languages - Konkani (spoken in Goa and neighboring states), Manipuri or Meitei (official language of Manipur), and Nepali (spoken in Sikkim, Darjeeling, and parts of Northeast India) - increasing the total to 18 languages.
• 92nd Amendment Act, 2003: Added four languages - Bodo, Dogri, Maithili, and Santhali - bringing the current total to 22 scheduled languages, recognizing India's vast linguistic diversity.
• Significance of Scheduled Languages: Languages in the Eighth Schedule are entitled to representation on official language commissions, can be used in UPSC and other competitive examinations, and receive government support for their development and promotion.
• Classical Languages: Six languages have been accorded 'Classical Language' status separately - Tamil (2004), Sanskrit (2005), Kannada (2008), Telugu (2008), Malayalam (2013), and Odia (2014). This status is distinct from scheduled language status and recognizes ancient literary heritage.
• Criteria for Inclusion: Though no fixed constitutional criterion exists, languages with significant number of speakers, rich literary tradition, and cultural significance are generally considered. Several languages including Tulu, Bhojpuri, and Rajasthani have ongoing demands for inclusion.
• Constitutional Provisions: Article 344 provides for the Constitution of a Commission and a Committee of Parliament on official languages. Article 351 directs the Union to promote Hindi and draw upon Sanskrit and other Eighth Schedule languages for its enrichment.
