Sino-Tibetan Languages — Key Changes

Entry	Year	Description	Impact
71st Amendment	1992	The Constitution (Seventy-first Amendment) Act, 1992 amended the Eighth Schedule to include Konkani, Manipuri and Nepali. Manipuri is the directly relevant language in this topic; the three additions do not belong to one genealogical family merely because they appear in the same Act.	Separates constitutional recognition from linguistic classification. Manipuri’s inclusion is a legal milestone, not the date when the language originated or evidence that every Sino-Tibetan language is scheduled.
92nd Amendment	2003	The Constitution (Ninety-second Amendment) Act, 2003 inserted Bodo, Dogri, Maithili and Santhali into the Eighth Schedule and renumbered entries. Although its short title contains 2003, it received assent and took effect on 7 January 2004. Bodo is the directly relevant addition for the present topic.	Bodo and Manipuri reached the Eighth Schedule through different amendments. The 92nd Act’s other additions demonstrate that a legal list crosses language-family boundaries: constitutional recognition is not a family classification or a common-script requirement.
