Language family concentrated in Southeast Asia

The Austroasiatic languages (,/ɒ//s//t//r//oʊ//.//eɪ//ʒ//i/'/æ//t//ɪ//k//, /,/ɔː// / ) are a large language family spoken throughout mainland Southeast Asia, South Asia and East Asia. These languages are natively spoken by the majority of the population in Vietnam and Cambodia, and by minority populations scattered throughout parts of Thailand, Laos, India, Myanmar, Malaysia, Bangladesh, Nepal, and southern China. Approximately 117 million people speak an Austroasiatic language, of which more than two thirds are Vietnamese speakers. Of the Austroasiatic languages, only Vietnamese, Khmer, and Mon have lengthy, established presences in the historical record. Only two are presently considered to be the national languages of sovereign states: Vietnamese in Vietnam, and Khmer in Cambodia. The Mon language is a recognized indigenous language in Myanmar and Thailand, while the Wa language is a "recognized national language" in the de facto autonomous Wa State within Myanmar. Santali is one of the 22 scheduled languages of India. The remainder of the family's languages are spoken by minority groups and have no official status. Ethnologue identifies 168 Austroasiatic languages. These form thirteen established families (plus perhaps Shompen, which is poorly attested, as a fourteenth), which have traditionally been grouped into two, as Mon–Khmer, and Munda. However, one recent classification posits three groups (Munda, Mon Khmer, and Khasi–Khmuic), while another has abandoned Mon–Khmer as a taxon altogether, making it synonymous with the larger family. Austroasiatic languages appear to be the extant autochthonous languages in mainland Southeast Asia, with the neighboring Kra–Dai, Hmong Mien, Austronesian, and Sino Tibetan languages having arrived via later migrations. Despite the literal meaning of its name, only three Austroasiatic branches are actually spoken in South Asia: Khasic, Munda, and Nicobarese.

Regarding word structure, Austroasiatic languages are well known for having an iambic "sesquisyllabic" pattern, with basic nouns and verbs consisting of an initial, unstressed, reduced minor syllable followed by a stressed, full syllable. This reduction of presyllables has led to a variety of phonological shapes of the same original Proto Austroasiatic prefixes, such as the causative prefix, ranging from CVC syllables to consonant clusters to single consonants among the modern languages. As for word formation, most Austroasiatic languages have a variety of derivational prefixes, many have infixes, but suffixes are almost completely non existent in most branches except Munda, and a few specialized exceptions in other Austroasiatic branches. The Austroasiatic languages are further characterized as having unusually large vowel inventories and employing some sort of register contrast, either between modal (normal) voice and breathy (lax) voice or between modal voice and creaky voice. Languages in the Pearic branch and some in the Vietic branch can have a three or even four way voicing contrast. However, some Austroasiatic languages have lost the register contrast by evolving more diphthongs or in a few cases, such as Vietnamese, tonogenesis. Vietnamese has been so heavily influenced by Chinese that its original Austroasiatic phonological quality is obscured and now resembles that of South Chinese languages, whereas Khmer, which had more influence from Sanskrit, has retained a more typically Austroasiatic structure.

Linguists traditionally recognize two primary divisions of Austroasiatic: the Mon–Khmer languages of Southeast Asia, Northeast India and the Nicobar Islands, and the Munda languages of East and Central India and parts of Bangladesh and Nepal. However, no evidence for this classification has ever been published. Each of the families that is written in boldface type below is accepted as a valid clade. By contrast, the relationships between these families within Austroasiatic are debated. In addition to the traditional classification, two recent proposals are given, neither of which accepts traditional "Mon–Khmer" as a valid unit. However, little of the data used for competing classifications has ever been published, and therefore cannot be evaluated by peer review. In addition, there are suggestions that additional branches of Austroasiatic might be preserved in substrata of Acehnese in Sumatra (Diffloth), the Chamic languages of Vietnam, and the Land Dayak languages of Borneo (Adelaar 1995).

Paul Sidwell (2009), in a lexicostatistical comparison of 36 languages which are well known enough to exclude loanwords, finds little evidence for internal branching, though he did find an area of increased contact between the Bahnaric and Katuic languages, such that languages of all branches apart from the geographically distant Munda and Nicobarese show greater similarity to Bahnaric and Katuic the closer they are to those branches, without any noticeable innovations common to Bahnaric and Katuic. He therefore takes the conservative view that the thirteen branches of Austroasiatic should be treated as equidistant on current evidence. Sidwell & Blench (2011) discuss this proposal in more detail, and note that there is good evidence for a Khasi–Palaungic node, which could also possibly be closely related to Khmuic. If this would the case, Sidwell & Blench suggest that Khasic may have been an early offshoot of Palaungic that had spread westward. Sidwell & Blench (2011) suggest Shompen as an additional branch, and believe that a Vieto Katuic connection is worth investigating. In general, however, the family is thought to have diversified too quickly for a deeply nested structure to have developed, since Proto Austroasiatic speakers are believed by Sidwell to have radiated out from the central Mekong river valley relatively quickly. Subsequently, Sidwell (2015a: 179) proposed that Nicobarese subgroups with Aslian, just as how Khasian and Palaungic subgroup with each other. A subsequent computational phylogenetic analysis (Sidwell 2015b) suggests that Austroasiatic branches may have a loosely nested structure rather than a completely rake like structure, with an east–west division (consisting of Munda, Khasic, Palaungic, and Khmuic forming a western group as opposed to all of the other branches) occurring possibly as early as 7,000 years before present. However, he still considers the subbranching dubious. Integrating computational phylogenetic linguistics with recent archaeological findings, Paul Sidwell (2015c) further expanded his Mekong riverine hypothesis by proposing that Austroasiatic had ultimately expanded into Indochina from the Lingnan area of southern China, with the subsequent Mekong riverine dispersal taking place after the initial arrival of Neolithic farmers from southern China. Sidwell (2015c) tentatively suggests that Austroasiatic may have begun to split up 5,000 years B. P. during the Neolithic transition era of mainland Southeast Asia, with all the major branches of Austroasiatic formed by 4,000 B. P. Austroasiatic would have had two possible dispersal routes from the western periphery of the Pearl River watershed of Lingnan, which would have been either a coastal route down the coast of Vietnam, or downstream through the Mekong River via Yunnan. considers the Austroasiatic language family to have rapidly diversified around 4,000 years B. P. during the arrival of rice agriculture in Indochina, but notes that the origin of Proto Austroasiatic itself is older than that date. The lexicon of Proto Austroasiatic can be divided into an early and late stratum. The early stratum consists of basic lexicon including body parts, animal names, natural features, and pronouns, while the names of cultural items (agriculture terms and words for cultural artifacts, which are reconstructible in Proto Austroasiatic) form part of the later stratum. Roger Blench (2017) suggests that vocabulary related to aquatic subsistence strategies (such as boats, waterways, river fauna, and fish capture techniques) can be reconstructed for Proto Austroasiatic. Blench (2017) finds widespread Austroasiatic roots for 'river, valley', 'boat', 'fish', 'catfish sp. ', 'eel', 'prawn', 'shrimp' (Central Austroasiatic), 'crab', 'tortoise', 'turtle', 'otter', 'crocodile', 'heron, fishing bird', and 'fish trap'. Archaeological evidence for the presence of agriculture in northern Indochina (northern Vietnam, Laos, and other nearby areas) dates back to only about 4,000 years ago (2,000 BC), with agriculture ultimately being introduced from further up to the north in the Yangtze valley where it has been dated to 6,000 B. P. proposes that the locus of Proto Austroasiatic was in the Red River Delta area about 4,000 4,500 years before present, instead of the Middle Mekong as he had previously proposed. Austroasiatic dispersed coastal maritime routes and also upstream through river valleys. Khmuic, Palaungic, and Khasic resulted from a westward dispersal that ultimately came from the Red Valley valley. Based on their current distributions, about half of all Austroasiatic branches (including Nicobaric and Munda) can be traced to coastal maritime dispersals. Hence, this points to a relatively late riverine dispersal of Austroasiatic as compared to Sino Tibetan, whose speakers had a distinct non riverine culture. In addition to living an aquatic based lifestyle, early Austroasiatic speakers would have also had access to livestock, crops, and newer types of watercraft. As early Austroasiatic speakers dispersed rapidly via waterways, they would have encountered speakers of older language families who were already settled in the area, such as Sino Tibetan. (quoted in Sidwell 2021) gives a more nested classification of Austroasiatic branches as suggested by his computational phylogenetic analysis of Austroasiatic languages using a 200 word list. Many of the tentative groupings are likely linkages. Pakanic and Shompen were not included.

Austroasiatic is an integral part of the controversial Austric hypothesis, which also includes the Austronesian languages, and in some proposals also the Kra–Dai languages and the Hmong–Mien languages.

Several lexical resemblances are found between the Hmong Mien and Austroasiatic language families (Ratliff 2010), some of which had earlier been proposed by Haudricourt (1951). This could imply a relation or early language contact along the Yangtze. According to Cai (et al. 2011), Hmong–Mien people are genetically related to Austroasiatic speakers, and their languages were heavily influenced by Sino Tibetan, especially Tibeto Burman languages.

It is suggested that the Austroasiatic languages have some influence on Indo Aryan languages including Sanskrit and middle Indo Aryan languages. Indian linguist Suniti Kumar Chatterji pointed that a specific number of substantives in languages such as Hindi, Punjabi and Bengali were borrowed from Munda languages. Additionally, French linguist Jean Przyluski suggested a similarity between the tales from the Austroasiatic realm and the Indian mythological stories of Matsyagandha (Satyavati from Mahabharata) and the Nāgas.

Mitsuru Sakitani suggests that Haplogroup O1b1, which is common in Austroasiatic people and some other ethnic groups in southern China, and haplogroup O1b2, which is common in today's Japanese and Koreans, are the carriers of early rice agriculture from southern China. Another study suggests that the haplogroup O1b1 is the major Austroasiatic paternal lineage and O1b2 the "para Austroasiatic" lineage of the Koreans and Yayoi people. A full genomic study by Lipson et al. (2018) identified a characteristic lineage that can be associated with the spread of Austroasiatic languages in Southeast Asia and which can be traced back to remains of Neolithic farmers from Mán Bạc (c. 2000 BCE) in the Red River Delta in northern Vietnam, and to closely related Ban Chiang and Vat Komnou remains in Thailand and Cambodia respectively. This Austroasiatic lineage can be modeled as a sister group of the Austronesian peoples with significant admixture (ca. 30%) from a deeply diverging eastern Eurasian source (modeled by the authors as sharing some genetic drift with the Onge, a modern Andamanese hunter gatherer group) and which is ancestral to modern Austroasiatic speaking groups of Southeast Asia such as the Mlabri and the Nicobarese, and partially to the Austroasiatic Munda speaking groups of South Asia (e. g. the Juang). Significant levels of Austroasiatic ancestry were also found in Austronesian speaking groups of Sumatra and Borneo. Austroasiatic speaking groups in southern China (such as the Wa and Blang in Yunnan) predominatly carry the same Mainland Southeast Asian Neolithic farmer ancestry, but with additional geneflow from northern and southern East Asian lineages that can be associated with the spread of Tibeto Burman and Kra Dai languages, respectively.

According to Chaubey et al., "Austro Asiatic speakers in India today are derived from dispersal from Southeast Asia, followed by extensive sex specific admixture with local Indian populations." According to Riccio et al., the Munda peoples are likely descended from Austroasiatic migrants from Southeast Asia. According to Zhang et al., Austroasiatic migrations from Southeast Asia into India took place after the Last Glacial Maximum, circa 10,000 years ago. Arunkumar et al., suggest Austroasiatic migrations from Southeast Asia occurred into Northeast India 5.2 ± 0.6 kya and into East India 4.3 ± 0.2 kya.
