Sidwell (2008) gives the following phonological shapes for two types of stems. * Monosyllabic - C(R)V(V)C * Sesquisyllabic - CCV(V)C ''Note'': R is one of the optional medial consonants /r, l, j, w, h/.

(2012) notes that Austroasiatic and Sino-Tibetan share many similarities regarding word structure, particularly nominal affixes (otherwise known as

s or minor syllable prefixes). Blench (2012) does not make any definitive conclusions about how these similarities could have arisen, but suggests that this typological diffusion might have come about as a result of intensive contact in an area between northern Vietnam, Laos, and northeast Myanmar.

Syntax

Like the

Origin and dispersal

Theories of the Austroasiatic homeland and dispersal have evolved rapidly in the 21st century. Proto-Austroasiatic migration

(2009) suggested that the likely homeland of Austroasiatic is in the

region, and that the family is not as old as frequently assumed, dating to perhaps 2,000 BCE. However, Peiros (2011) criticized Sidwell's 2009 riverine dispersal hypothesis heavily and claimed many contradictions. He showed with his analysis that the homeland of Austroasiatic is somewhere near the

as likely homeland of proto-Austroasiatic before they migrated to other parts of central and southern China and then into Southeast Asia. He further suggests that the family must be as old as proto-Austronesian and proto-Sino-Tibetan or even older. Georg van Driem (2011) proposed that the homeland of Austroasiatic is somewhere in southern China. He suggested that the region around the

is the likely homeland of the Austroasiatic languages and people. He further suggested, based on genetic studies, that the migration of Kra–Dai people from Taiwan replaced the original Austroasiatic language but the effect on the people was only minor. Local Austroasiatic speakers adopted Kra-Dai languages and partially their culture. The linguists Sagart (2011) and Bellwood (2013) supported the theory of an origin of Austroasiatic along the

. Both the reconstructed lexicon of Proto-Austroasiatic and the archaeological record clearly show that early Austroasiatic speakers around 4,000 B.P. cultivated rice and millet, kept livestock such dogs, pigs, and chickens, and thrived mostly in estuarine rather than coastal environments. At 4,500 B.P., this "Neolithic package" suddenly arrived in Indochina from the Lingnan area without cereal grains and displaced the earlier pre-Neolithic hunter-gatherer cultures, with grain husks found in northern Indochina by 4,100 B.P. and in southern Indochina by 3,800 B.P. However, Sidwell found that iron is not reconstructable in Proto-Austroasiatic, since each Austroasiatic branch has different terms for iron that had been borrowed relatively lately from Tai, Chinese, Tibetan, Malay, and other languages. During the

about 2,500 B.P., relatively young Austroasiatic branches in Indochina such as Vietic, Katuic, Pearic, and Khmer were formed, while the more internally diverse Bahnaric branch (dating to about 3,000 B.P.) underwent more extensive internal diversification. By the Iron Age, all of the Austroasiatic branches were more or less in their present-day locations, with most of the diversification within Austroasiatic taking place during the Iron Age. Paul Sidwell (2018)Sidwell, Paul. 2018. ''Austroasiatic deep chronology and the problem of cultural lexicon''. Paper presented at the 28th Annual Meeting of the Southeast Asian Linguistics Society, held May 17–19, 2018 in Kaohsiung, Taiwan. 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 reconstructable in Proto-Austroasiatic) form part of the later stratum.

Waterworld: lexical evidence for aquatic subsistence strategies in Austroasiatic
'. Presented at ICAAL 7, Kiel, Germany. 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 (2018) 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

(northern Vietnam, Laos, and other nearby areas) dates back to only about 4,000 years B.P. (2,000 B.C.), 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. 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. Sidwell (2021)

/ref> proposes that the locus of Proto-Austroasiatic was in the

area about 4,000-4,500 years before present. 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 River valley. Based on their current distributions, about half of all Austroasiatic branches (including Nicobaric and Munda) can be traced to coastal maritime dispersals.
