Languages of India: language families, scripts and the Eighth Schedule

In short

India's roughly 121 census languages and 1,369 rationalised mother tongues belong to five or six distinct language families, are written in a dozen living scripts (almost all descended from Brahmi, plus Perso-Arabic and Roman), and are governed by a constitutional scheme whose centrepiece is the Eighth Schedule's list of 22 languages. The topic sits at the start of every BA Indian-language syllabus because it supplies the map on which literature, grammar and dialectology are later placed. It is examined in university Paper-I "Language foundations", in UGC-NET Paper-II for every Indian language, and in UPSC/State PSC general studies. For jobs it matters directly: UPSC and most State PSCs allow answers in any Eighth Schedule language, translators and localisation staff are hired by language pair, and Sahitya Akademi, NCERT, NCPUL and the Bhashini programme all organise work by this same list.

Explained

The language families present in India

• Indo-Aryan (branch of Indo-European, via Old Indo-Aryan → Prakrits/Apabhramsha → New Indo-Aryan): Hindi, Bengali, Marathi, Gujarati, Urdu, Odia, Punjabi, Assamese, Maithili, Kashmiri (Dardic sub-group), Nepali, Sindhi, Dogri, Konkani, Sanskrit. About 77% of speakers (census family grouping, approximate).
• Dravidian: South Dravidian (Tamil, Malayalam, Kannada, Tulu, Kodava), South-Central (Telugu, Gondi, Kui), Central (Kolami, Parji), North (Kurukh, Malto, and Brahui in Pakistan). About 20% of speakers. Dravidian is not derived from Sanskrit; the two families are genetically unrelated but heavily in contact.
• Austroasiatic (Munda and Khasic): Santali, Mundari, Ho, Korku, Savara; Khasi and Nicobarese belong to the Mon-Khmer side. About 1.1%.
• Tibeto-Burman (Sino-Tibetan): Manipuri/Meiteilon, Bodo, Garo, Mizo, Naga group, Ladakhi, Lepcha, Tripuri. About 1.0%.
• Tai-Kadai: a small presence in Assam/Arunachal — Khamti, Aiton, Phake.
• Great Andamanese (a family of its own) and Ongan (Onge, Jarawa); Nihali in Maharashtra/MP is usually treated as a language isolate. Also Arabic-origin Afro-Asiatic speech in tiny numbers.
• India as a linguistic area (Sprachbund) — M. B. Emeneau, 1956: unrelated families here share retroflex consonants, SOV word order, conjunctive participles, dative/experiencer subjects, echo words (chai-vai), quotative constructions and extensive borrowing. This convergence, not common descent, explains much of the "Indian" feel of all the languages.

Counting the languages: surveys and the census

• Linguistic Survey of India (LSI), Sir George Abraham Grierson, 1898–1928, 11 volumes: 179 languages and 544 dialects — the first systematic survey, still cited for 19th-century data.
• New Linguistic Survey of India is run by the Office of the Registrar General and Census Commissioner (ORGI); the People's Linguistic Survey of India (G. N. Devy, 2010–13), a non-official effort, reported about 780 living languages.
• Census method: every respondent's returned mother tongue is recorded; raw returns are rationalised into mother tongues, which are then grouped under a language. Census 2011 had 19,569 raw returns → 1,369 rationalised mother tongues → 121 languages with 10,000 or more speakers, of which 22 are scheduled and 99 non-scheduled.
• Grouping is why "Hindi" is so large: Bhojpuri (about 5.05 crore), Rajasthani, Magahi, Chhattisgarhi, Haryanvi, Marwari and dozens more are counted as mother tongues *under* the Hindi language total of 52.83 crore.
• Bilingualism (Census 2011): about 26% of Indians are bilingual and about 7% trilingual. Census 2011 remains the latest published language data; the next census enumeration is scheduled for 2027 and its language tables are not yet out.
• Endangerment: UNESCO's atlas lists around 197 languages in India as endangered — the highest for any country. The Scheme for Protection and Preservation of Endangered Languages (SPPEL), run through the Central Institute of Indian Languages (CIIL), Mysuru, documents languages with fewer than 10,000 speakers.

The Eighth Schedule: what it is and how it grew

• The Eighth Schedule is referred to in Article 344(1) (composition of the Official Language Commission) and Article 351 (the Union's duty to develop Hindi by drawing vocabulary primarily from Sanskrit and secondarily from the other scheduled languages). It is not a list of "national languages" — the Constitution names no national language.
• Original 14 (1950): Assamese, Bengali, Gujarati, Hindi, Kannada, Kashmiri, Malayalam, Marathi, Oriya, Punjabi, Sanskrit, Tamil, Telugu, Urdu.
• 21st Amendment, 1967: Sindhi (15).
• 71st Amendment, 1992: Konkani, Manipuri, Nepali (18).
• 92nd Amendment, 2003: Bodo, Dogri, Maithili, Santali (22).
• 96th Amendment, 2011: "Oriya" renamed "Odia" — a renaming, not an addition.
• Consequences of inclusion: candidates may write UPSC and many PSC examinations in the language; it is represented on the Official Language Commission and in the Commission for Scientific and Technical Terminology's work; it gets Sahitya Akademi and National Book Trust support and central development schemes. The Sahitya Akademi actually recognises 24 literatures — the 22 plus English and Rajasthani.
• Pending demands: more than 35 languages seek inclusion, most prominently Bhojpuri, Rajasthani, Tulu, Mizo, Khasi, Garhwali, Kumaoni, Bhoti, Gondi, Mundari, Kodava, Angika, Magahi, Chhattisgarhi. The Sitakant Mahapatra Committee (2003) examined criteria; the Government's standing position is that no fixed set of criteria has been settled, because any definition of "language" versus "dialect" is contested.

The constitutional and statutory framework

• Article 343: the official language of the Union is Hindi in the Devanagari script, with international numerals; English was to continue for 15 years (to 1965).
• Official Languages Act, 1963, s.3: English continues alongside Hindi for Union purposes indefinitely, and shall continue so long as any non-Hindi State's legislature has not resolved otherwise. Official Languages Rules, 1976 classify States/UTs into Region A (Hindi-speaking), Region B (Gujarat, Maharashtra, Punjab, Chandigarh, Daman & Diu, Dadra & Nagar Haveli; Andaman & Nicobar is in Region A) and Region C (the rest) and fix correspondence rules.
• Article 344: Official Language Commission and the Committee of Parliament on Official Language.
• Article 345: a State legislature may adopt any language in use in the State, or Hindi, as its official language. Article 346 (inter-State and State-Union communication), Article 347 (President may recognise a language spoken by a substantial section of a State's population).
• Article 348: proceedings of the Supreme Court and High Courts, and the authoritative texts of Bills and Acts, shall be in English; a Governor may, with the President's prior consent, authorise Hindi or another State language in that High Court (done for Rajasthan, Uttar Pradesh, Madhya Pradesh and Bihar) — this does not extend to judgments' authoritative text without further provision.
• Article 29: any section of citizens having a distinct language, script or culture has the right to conserve it. Article 30: minorities, including linguistic minorities, may establish and administer educational institutions.
• Article 350: representation for redress of grievances in any language used in the Union or State. Article 350A: facilities for instruction in the mother tongue at the primary stage for linguistic-minority children. Article 350B: a Special Officer for Linguistic Minorities (the Commissioner for Linguistic Minorities, with headquarters at Allahabad/Prayagraj), appointed by the President, reporting to Parliament.
• Article 120 / Article 210: business in Parliament and State legislatures in Hindi or English (or the State language), with a member permitted to address in their mother tongue with the Chair's permission.
• Three-language formula: proposed in the 1968 National Policy on Education, restated in NPE 1986 and in NEP 2020, which keeps it flexible — no language is imposed, at least two of the three must be native to India, and the medium until at least Class 5 (preferably Class 8) should be the home/mother tongue where possible.
• Institutions: CIIL Mysuru; Central Hindi Directorate and Kendriya Hindi Sansthan, Agra; Commission for Scientific and Technical Terminology (CSTT); National Council for Promotion of Urdu Language (NCPUL) and for Sindhi (NCPSL); Central Sanskrit University; Central Institute of Classical Tamil; Bharatiya Bhasha Samiti.
• Classical-language status is a separate recognition from the Eighth Schedule, conferred by the Ministry of Culture; eleven languages now hold it, including the six recognised between 2004 and 2014 (Tamil, Sanskrit, Telugu, Kannada, Malayalam, Odia) and the five added in October 2024 (Marathi, Pali, Prakrit, Assamese, Bengali). The criteria and literary arguments are treated in the separate note on classical languages.

Scripts: origins, type and the living set

• Brahmi is the ancestor of nearly every Indian script; attested in the Ashokan edicts of the 3rd century BCE and deciphered by James Prinsep (1837). Kharosthi, used in Gandhara, ran right-to-left and died out by about the 4th century CE. The Indus script remains undeciphered.
• Brahmic scripts are abugidas (alphasyllabaries), not alphabets: the basic unit is the akshara, a consonant carrying an inherent vowel /a/; other vowels are written with matras; the virama/halant kills the inherent vowel; consonant clusters form conjuncts (samyuktakshara).
• The varnamala is phonetically ordered — vowels first, then stops arranged by place (velar → labial) and by manner (unvoiced/voiced × unaspirated/aspirated, plus nasal), then semivowels, sibilants and /h/. This order is itself an exam point: it is why Indian dictionaries sort differently from Roman ones.
• Northern (Nagari) group: Devanagari, Bengali-Assamese, Gurmukhi, Gujarati, Odia, Tirhuta/Mithilakshar, Sharada and Takri, Modi, Tibetan.
• Southern group: Tamil, Telugu-Kannada (from Kadamba), Malayalam (from Vatteluttu and Grantha), Sinhala; the South-East Asian scripts (Thai, Khmer, Javanese, Burmese) also descend from southern Brahmi.
• Non-Brahmic in use: Perso-Arabic (Nastaliq style for Urdu, Naskh for Sindhi and Kashmiri) and Roman (Konkani in Goa, Mizo, Khasi, Nagamese and most North-East Christian-missionary orthographies).
• Modern invented scripts: Ol Chiki for Santali (Raghunath Murmu, 1925) and Meitei Mayek, a revived old script now taught in Manipur alongside the Bengali script.
• Script-specific points often asked: Tamil has no separate letters for voiced or aspirated stops (voicing is allophonic) and uses Grantha letters for Sanskrit sounds; Odia's rounded head-mark comes from palm-leaf stylus writing; Gurmukhi was standardised by Guru Angad; Malayalam has both old and reformed (1971 *puthiya lipi*) orthographies.
• A script is not tied to one language: Devanagari serves Hindi, Marathi, Nepali, Sanskrit, Bodo, Dogri, Maithili and Konkani; Urdu and Hindi share grammar and core vocabulary but use different scripts and different learned vocabularies (Persian/Arabic versus Sanskrit).

Key points

• Eighth Schedule - the constitutional list of 22 languages, referred to in Articles 344(1) and 351; not a list of national languages.
• 14 → 22 - 14 at commencement, +Sindhi (21st Amdt, 1967), +Konkani, Manipuri, Nepali (71st, 1992), +Bodo, Dogri, Maithili, Santali (92nd, 2003); Oriya renamed Odia (96th, 2011).
• Article 343 - Hindi in Devanagari is the Union's official language; Official Languages Act, 1963, s.3 keeps English alongside it indefinitely.
• Article 348 - Supreme Court and High Court proceedings and authoritative texts of laws are in English, subject to presidential authorisation for a High Court.
• Article 350A / 350B - mother-tongue primary instruction for linguistic minorities; Special Officer (Commissioner) for Linguistic Minorities.
• Five-plus families - Indo-Aryan (~77%), Dravidian (~20%), Austroasiatic (~1.1%), Tibeto-Burman (~1.0%), Tai-Kadai, Great Andamanese; Nihali is an isolate.
• Census 2011 - 121 languages, 1,369 rationalised mother tongues, 22 scheduled covering 96.71% of the population.
• Hindi 43.63% - 52.83 crore, inflated by grouping Bhojpuri, Rajasthani, Magahi and others as its mother tongues.
• Sanskrit - scheduled, with only 24,821 returned speakers in 2011; the smallest scheduled language by speakers.
• Abugida - a Brahmic akshara is a consonant plus inherent /a/, modified by matras and cancelled by virama.
• Brahmi - common ancestor of Indian and most South-East Asian scripts; Kharosthi was right-to-left and died out; Indus script undeciphered.
• Script ≠ language - Devanagari serves eight scheduled languages; Sindhi and Manipuri each use two scripts officially.
• Sprachbund - Emeneau's "India as a linguistic area": retroflexion, SOV order, echo words and dative subjects cut across families.
• LSI - Grierson's survey (1898–1928) found 179 languages and 544 dialects; PLSI (2013) counted about 780.
• Three-language formula - NPE 1968 onwards, restated flexibly in NEP 2020; at least two of the three languages native to India.
• Pending claims - Bhojpuri, Rajasthani, Tulu, Mizo, Khasi and about 30 others; Sitakant Mahapatra Committee (2003) looked at criteria, none finally notified.
• Endangerment - about 197 Indian languages listed as endangered by UNESCO; SPPEL at CIIL Mysuru documents those under 10,000 speakers.

Formulas and examples

Example 1 — Hindi's share, Census 2011. Speakers 52,83,47,193; total population 1,21,08,54,977. Share = 528,347,193 ÷ 1,210,854,977 = 0.43634 → 43.63%. Note what this hides: Bhojpuri alone contributes about 5.05 crore (≈4.17%) inside that figure.

Example 2 — non-scheduled speakers. Scheduled languages cover 96.71%. Non-scheduled = 100 − 96.71 = 3.29%. In people: 0.0329 × 1,210,854,977 ≈ 3.98 crore — more than the whole Malayalam-speaking population (3.48 crore), spread over 99 languages.

Example 3 — Devanagari's reach. Add the scheduled languages officially written in Devanagari: Hindi 43.63 + Marathi 6.86 + Maithili 1.12 + Nepali 0.24 + Dogri 0.21 + Konkani 0.19 + Bodo 0.12 + Sanskrit ≈ 0.00 = 52.37% of the population. Dravidian scheduled languages: Telugu 6.70 + Tamil 5.70 + Kannada 3.61 + Malayalam 2.88 = 18.89%.

Example 4 — Linguistic Diversity Index for a simplified State. Mother-tongue proportions: Marathi 0.70, Hindi 0.12, Urdu 0.07, all others 0.11. Σpᵢ² = 0.4900 + 0.0144 + 0.0049 + 0.0121 = 0.5214. LDI = 1 − 0.5214 = 0.479 — roughly a 48% chance that two randomly chosen residents have different mother tongues. (Using a single "others" bucket understates diversity; splitting it would raise the LDI.)

Example 5 — amendment arithmetic. 14 (1950) + 1 (1967) + 3 (1992) + 4 (2003) = 22, reached in 2003; the 96th Amendment of 2011 changed a name only, so the count has stood at 22 since 2003.

Where it is used

• Translation and localisation: publishing houses, subtitling and OTT localisation, legal and government translation cells; pay and hiring are organised by language pair, and the 22 scheduled languages define the commercially serviced set.
• Government and public-sector jobs: Rajbhasha/Official Language officers and Junior Translators in ministries, banks and PSUs under the Official Languages Act and Rules; State PSC and IBPS recruitment include a local-language proficiency test.
• Education and research: State board and CBSE language teaching (TET, NET/JRF in the specific language), NCERT and SCERT textbook development, mother-tongue primary instruction required for linguistic minorities under Article 350A.
• Media and content: regional newspapers, radio and news channels, and the bulk of India's new digital audience, which is non-English — editorial, scripting and voice-over roles track the family and script map above.
• Language technology: speech and text data collection, annotation and evaluation for the Bhashini programme and private AI teams; a linguist's knowledge of family, script and mother-tongue grouping is exactly what dataset design needs.
• Culture and heritage: Sahitya Akademi, National Book Trust, CIIL and SPPEL documentation of endangered languages; museum, archive and epigraphy roles requiring script history.

Interview questions

• Q: Is Hindi the national language of India? A: No. The Constitution designates Hindi in Devanagari as the official language of the Union under Article 343 and names no national language; English continues as an associate official language under the Official Languages Act, 1963.
• Q: How many languages are in the Eighth Schedule and how did it reach that number? A: 22 — 14 originally, plus Sindhi (1967), Konkani, Manipuri and Nepali (1992), and Bodo, Dogri, Maithili and Santali (2003).
• Q: What does a language actually gain by being put in the Eighth Schedule? A: Eligibility as a medium in UPSC and many State examinations, representation in the Official Language Commission and terminology work, and access to Sahitya Akademi and central development funding; it does not by itself make the language official in any State.
• Q: Which language families are represented in India? A: Indo-Aryan, Dravidian, Austroasiatic (Munda and Khasic), Tibeto-Burman and Tai-Kadai, plus the Andamanese families and the isolate Nihali.
• Q: Which scheduled languages are not Indo-Aryan? A: Tamil, Telugu, Kannada and Malayalam (Dravidian), Santali (Austroasiatic), and Manipuri and Bodo (Tibeto-Burman).
• Q: What is an abugida and why does it matter for Indian scripts? A: A writing system where each consonant letter carries an inherent vowel that is altered by matras or cancelled by a virama; it makes the syllable-like akshara, not the letter, the basic unit of reading, sorting and typing.
• Q: Hindi and Urdu are often called one language — explain. A: They share Khari Boli grammar and core vocabulary and are mutually intelligible in everyday speech, but differ in script (Devanagari versus Perso-Arabic Nastaliq) and in learned vocabulary drawn from Sanskrit versus Persian and Arabic.
• Q: Why is Hindi's census figure disputed? A: Because the census groups dozens of distinct mother tongues — Bhojpuri, Rajasthani, Magahi, Chhattisgarhi and others, several with crore-scale speaker bases — under the Hindi language total.
• Q: What is meant by "India as a linguistic area"? A: Emeneau's observation that unrelated Indian families converged through long contact, sharing retroflex consonants, SOV order, conjunctive participles, dative subjects and echo-word formation.
• Q: Which script does Santali use, and why is that significant? A: Ol Chiki, devised by Raghunath Murmu in 1925 — it shows that a modern purpose-built script, not only a Brahmi descendant, can carry a scheduled language.
• Q: What protection does the Constitution give a linguistic minority? A: Article 29 protects the right to conserve its language and script, Article 30 allows it to run educational institutions, Article 350A provides mother-tongue primary instruction, and Article 350B creates a Special Officer for Linguistic Minorities.
• Q: In what language must High Court proceedings be conducted? A: English under Article 348, unless the Governor, with the President's prior consent, authorises Hindi or the State language for that High Court — done for Rajasthan, Uttar Pradesh, Madhya Pradesh and Bihar.

Common mistakes

• Calling Hindi the national language, or treating the Eighth Schedule as a list of national or official languages — it is neither.
• Saying there are 22 languages in India; there are 22 scheduled languages out of 121 census languages and over a thousand mother tongues.
• Claiming Dravidian languages descend from Sanskrit, or that Sanskrit is the mother of all Indian languages — Indo-Aryan descends from Old Indo-Aryan; the other families do not.
• Confusing language with script: Devanagari is not "Hindi script", and a change of script does not make a different language.
• Mixing up the amendment numbers and years (21st/1967, 71st/1992, 92nd/2003) or counting the 96th Amendment's Odia renaming as a 23rd language.
• Confusing Eighth Schedule status with classical-language status — different lists, different authorities, different criteria.
• Quoting Census 2011 shares as current without saying so; they are the latest published figures, with the 2027 census data still awaited.
