The Munda languages are a group of closely-related languages spoken by about eleven million people in India, Bangladesh and Nepal. Historically, they have been called the Kolarian languages. They constitute a branch of the Austroasiatic language family, which means they are distantly related to languages such as the Mon and Khmer languages, to Vietnamese, as well as to minority languages in Thailand and Laos and the minority Mangic languages of South China.Bradley (2012) notes, MK in the wider sense including the Munda languages of eastern South Asia is also known as Austroasiatic Bhumij, Ho, Mundari, and Santali are notable Munda languages.
The family is generally divided into two branches: North Munda, spoken in the Chota Nagpur Plateau of Jharkhand, Chhattisgarh, Bihar, Odisha and West Bengal, as well as in parts of Bangladesh and Nepal, and South Munda, spoken in central Odisha and along the border between Andhra Pradesh and Odisha.
North Munda, of which Santali is the most widely spoken and recognised as an official language in India, has twice as many speakers as South Munda. After Santali, the Mundari and Ho languages rank next in number of speakers, followed by Korku and Sora. The remaining Munda languages are spoken by small isolated groups and are poorly described.
General characteristics of the Munda languages include head-final clausal structure, the fusion of middle voice and active voice with tense-aspect-mood markers, a distinction between inclusive and exclusive first-person plural pronouns in the pronominal systems, the lack of grammatical gender as a productive category, the widespread use of numeral classifiers, and lexical words in referential function ("nouns") all have one invariable form, a distinction between alienable and inalienable possession, and rich and pervasive systems of auxiliary verb constructions (AVCs) in clausal structure. The Munda languages are generally synthetic and agglutinating. In Munda sound systems, consonant sequences are infrequent except in the middle of words.
The Munda languages are often interpreted as prime examples of father tongues since the majority of native speakers of these languages tend to display the Y-chromosome haplogroup of the original linguistic founding population in higher frequencies, and that Y-haplogroup signifies the linguistic origin, rather than based on a maternal haplogroup.
Origin Many linguists suggest that the Proto-Munda language probably split from Proto-Austroasiatic somewhere in Indochina. Studies by Chaubey et al. (2011), Arunkumaret al. (2015), Metspalu et al. (2018), and Tätte et al. (2019) all show that the Munda branch of the Austroasiatic family was created as the result of a male-biased linguistic intrusion into the Indian subcontinent from Southeast Asia during the Late Neolithic period (Sidwell & Rau 2019 cited Tätte et al. (2019), estimate a date of formation between 3,800 and 2,000 years ago), which carried the paternal lineage O1b1a1a into India from either Meghalaya or the sea. These studies and analyses confirm George van Driem's Munda Father tongue hypothesis. Paul Sidwell (2018) suggests they arrived on the coast of modern-day Odisha about 4000–3500 years ago ( BCE) and spread after the Indo-Aryan migration to the region.Sidwell, Paul. 2018.

Rau and Sidwell (2019),Rau, Felix and Paul Sidwell 2019. "The Maritime Munda Hypothesis." ICAAL 8, Chiang Mai, Thailand, 29–31 August 2019. along with Blench (2019),Blench, Roger. 2019. The Munda maritime dispersal: when, where and what is the evidence? suggest that Pre-Proto-Munda had arrived in the Mahanadi River Delta around 1500 BCE from Southeast Asia via a maritime route, rather than overland. The Munda languages then subsequently spread up the Mahanadi watershed. 2021 studies suggest that Munda languages impacted Eastern Indo-Aryan languages.Ivani, Jessica K; Paudyal, Netra; Peterson, John (2021).

Classification Internal classification
Diffloth (1974) The bipartite Diffloth (1974) classification is widely cited:
Munda North Munda Korku Kherwarian Kherwari branch: Birjia, Koraku Mundari branch: Mundari, Bhumij, Asuri, Koda, Ho, Birhor, Kol, Turi Santal branch: Santali, Mahali South Munda Kharia–Juang: Kharia, Juang Koraput Munda Remo branch: Gata (Gta), Bondo (Remo), Bodo Gadaba (Gutob) Savara branch [Sora–Juray–Gorum] : Parengi (Gorum), Sora (Savara), Juray, Lodhi
Diffloth (2005) Diffloth (2005) retains Koraput (rejected by Anderson, below) but abandons South Munda and places Kharia–Juang with the northern languages:
Anderson (1999) Anderson's 1999 proposal is as follows.Anderson, Gregory D.S. (1999). "A new classification of the Munda languages: Evidence from comparative verb morphology." Paper presented at 209th meeting of the American Oriental Society, Baltimore, MD.
Munda North Munda Korku Kherwarian: Santali, Mundari South Munda (3 branches) Kharia–Juang: Juang, Kharia Sora–Gorum: Sora, Gorum Gutob–Remo–Gtaʔ Gutob–Remo: Gutob, Remo Gtaʼ: Plains Gtaʔ, Hill Gtaʔ
However, in 2001, Anderson split Juang and Kharia apart from the Juang-Kharia branch and also excluded Gtaʔ from his former Gutob–Remo–Gtaʔ branch. Thus, his 2001 proposal included five branches for South Munda.
Anderson (2001) Anderson (2001) follows Diffloth (1974) apart from rejecting the validity of Koraput. He proposes instead, on the basis of morphological comparisons, that Proto-South Munda split directly into Diffloth's three daughter groups, Kharia–Juang, Sora–Gorum (Savara), and Gutob–Remo–Gtaʼ (Remo).
His South Munda branch contains the following five branches, but the North Munda branch is the same as those of Diffloth (1974) and Anderson (1999).
Note: "↔" = shares certain innovative isoglosses (structural, lexical). In Austronesian and Papuan linguistics, this has been called a "linkage" by Malcolm Ross.
Sidwell (2015) Paul Sidwell (2015) considers Munda to consist of 6 coordinate branches, and does not accept South Munda as a unified subgroup.

External classification Traditionally, the Austroasiatic phylum was divided into two primary groups, Mon-Khmer and Munda, following Schmidt (1906)'s classification. Sebeok (1942) and Pinnow (1959, 1960, 1963) later reinforced this model, attributing the distinction to the typological contrast between the geographically eastern Mon-Khmer (Pinnow's Khmer-Nicobar) and the South Asian Munda branch. This binary classification, however, overlooks lexical evidence, the effects of language contact and areal convergence that may have profoundly shaped the structure of individual branches. Pinnow (1963:150) himself acknowledged that his classification "[...]have only structural and geographical justification." As comparative-historical research progressed, alternative hypotheses concerning the external position of Munda emerged. During the 1970s and 1980s, Diffloth and Shorto independently came up with a hypothesis that suggests recognizing the phylum as made up of two Northern and Southern phylogenetic groups on the basis of shared lexical innovations and the *s-:*t- correspondence in minor syllables. Under this hypothesis, Munda formed part of the Northern group together with Khasian, Palaungic, Khmuic, Mang, and Vietic. Sidwell (2014), however, argues that Munda lacks convincing lexical and structural innovations linking it to this putative Northern subgroup. He further notes that the lexical isoglosses required to unite Mang-Pakanic with the Khasi-Palaungic group are also absent.
A computational phylogenetic analysis study conducted by Sidwell & Greenhill (2014) found no evidence supporting a higher-level Mon-Khmer v. Munda division. Instead, the Austroasiatic family was optimally resolved into eleven primary nodes, with Munda recovered as a coherent coordinate branch equivalent in rank to the other major lineages. The analysis therefore provides no support for treating Munda as the sister group of a monophyletic Mon-Khmer subgroup.
Sociolinguistics and history of Munda studies
The Munda languages are the least documented languages in South Asia. Most Munda languages, except Santali with ~8 million native speakers, can be tentatively described as under threat, with Mundari (~1.5 million), Ho (~1 million), Korku (~400,000), Kharia (~200,000), and Sora (~250,000–300,000) still maintaining substantial everyday usage; smaller South Munda languages such as Juang, Gtaʔ, Remo, Birhor, and Gorum survive in small, fragmented populations amidst more than half a billion Indo-Aryan and Dravidian speakers in one of the most densely populated regions on Earth. Speakers are concentrated in central and eastern India, especially Jharkhand, Odisha, West Bengal, Madhya Pradesh, Maharashtra, and adjacent regions, typically in hill and forest zones, which Peterson (2017) terms accretion zones. Literacy rates are usually low among speakers, and opportunities for daily communication to be written down are largely restricted to the larger languages. Multilingualism is widespread, with frequent use of Hindi, Bengali, Sardi, Odia, Marathi, Telugu, and other regional languages in administration, trade, and education.
Munda languages have long been affected by social stigmas because their speakers, mainly belonging to Adivasi, Dalit, and other socially marginalized communities, have historically occupied subordinate positions within the regional caste and socioeconomic hierarchy. Although folk literatures are abundant, it is not so surprising that the Munda languages lack written literature before the 19th century; the same can be said of other languages spoken by dalit and tribal communities (adivasi) of South Asia (Brahui, Kurukh, Bhili, Burushaski, Nihali, etc). Colonial and postcolonial attitudes often viewed tribal populations as "primitive" and backward, and these perceptions became attached to their languages, which dominant groups frequently regarded as rural and lacking prestige. The dominance of regional Indo-Aryan languages such as Hindi, Bengali, Odia, and Sardi in education, administration, religion, and public life further reinforced this hierarchy, constantly pressuring many Munda speakers to shift toward socially prestigious majority languages.
Long-term intense contact has led to extensive Aryanization. Some communities formerly associated with Munda languages have largely abandoned them and now speak Indo-Aryan varieties instead. Turi is a clear example: although it is genetically a North Munda language, most ethnic Turi no longer speak it fluently with just over 0.56% of the Turi population use the language in daily life. Birhor communities, meanwhile, increasingly adopt Sardi and Hindi. Similar pressures affect Kharia-speaking regions, where prolonged interaction with neighboring Indo-Aryan populations and Kherwarian groups has produced strong lexical and structural convergence. In several South Munda communities, monolingual speakers have disappeared entirely. Certain Indo-Aryan speaking groups in the lowland plain may have originally Munda speakers who went through Aryanization, such as the Cheros of Bihar, the Lohar weavers of Ranchi, the Musahars and Tharus of lowland Nepal, and the Sahariya of Eastern Uttar Pradesh.
