'''Sino-Tibetan''' (sometimes referred to as '''Trans-Himalayan'''){{sfnp|van Driem|2014|p=16}}{{sfnp|List|Lai|Starostin|2019|p=1}} is a [[language family|family]] of more than 400 languages, second only to [[Indo-European languages|Indo-European]] in number of native speakers.{{sfnp|Handel|2008|p=422}} Around 1.4 billion people speak a Sino-Tibetan language.<ref>{{Cite web|url=https://study.com/academy/lesson/sino-tibetan-languages-history-distribution-classification.html|title=Sino Tibetan Languages|access-date=December 30, 2023}}</ref> The vast majority of these are the 1.3 billion native speakers of [[Sinitic languages]]. Other Sino-Tibetan languages with large numbers of speakers include [[Burmese language|Burmese]] (33 million) and the [[Tibetic languages]] (6 million). Four [[United Nations]] member states ([[China]], [[Singapore]], [[Myanmar]], and [[Bhutan]]) have a Sino-Tibetan language as their main native language. Other languages of the family are spoken in the [[Himalayas]], the [[Southeast Asian Massif]], and the eastern edge of the [[Tibetan Plateau]]. Most of these have small speech communities in remote mountain areas, and as such are poorly documented.

Several low-level subgroups have been securely [[linguistic reconstruction|reconstructed]], but reconstruction of a [[proto-language]] for the family as a whole is still at an early stage, so the higher-level structure of Sino-Tibetan remains unclear. Although the family is traditionally presented as divided into [[Sinitic languages|Sinitic]] (i.e. Chinese languages) and [[Tibeto-Burman languages|Tibeto-Burman]] branches, a common origin of the non-Sinitic languages has never been demonstrated. The [[Kra–Dai languages|Kra–Dai]] and [[Hmong–Mien languages]] are generally included within Sino-Tibetan by Chinese linguists but have been excluded by the international community since the 1940s. Several [[classification schemes for Southeast Asian languages|links to other language families]] have been proposed, but none have broad acceptance.

==History==
A [[Genetic relationship (linguistics)|genetic relationship]] between Chinese, Tibetan, Burmese, and other languages was first proposed in the early 19th century and is now broadly accepted. The initial focus on languages of civilizations with long literary traditions has been broadened to include less widely spoken languages, some of which have only recently, or never, been written. However, the reconstruction of the family is much less developed than for families such as [[Indo-European languages|Indo-European]] or [[Austroasiatic languages|Austroasiatic]]. Difficulties have included the great diversity of the languages, the lack of inflection in many of them, and the effects of language contact. In addition, many of the smaller languages are spoken in mountainous areas that are difficult to reach and are often also sensitive border zones.{{sfnp|Handel|2008|pp=422, 434–436}} There is no consensus regarding the date and location of their origin.{{sfnp|Sagart|Jacques|Lai|Ryder|2019|p=10317}}

===Early work===
During the 18th century, several scholars noticed parallels between Tibetan and Burmese, both languages with extensive literary traditions. Early in the following century, [[Brian Houghton Hodgson]] and others noted that many non-literary languages of the highlands of northeast India and Southeast Asia were also related to these. The name "Tibeto-Burman" was first applied to this group in 1856 by [[James Richardson Logan]], who added [[Karen languages|Karen]] in 1858.{{sfnp|Logan|1856|p=31}}{{sfnp|Logan|1858}} The third volume of the ''[[Linguistic Survey of India]]'', edited by [[Sten Konow]], was devoted to the Tibeto-Burman languages of [[British India]].{{sfnp|Hale|1982|p=4}}

Studies of the "Indo-Chinese" languages of Southeast Asia from the mid-19th century by Logan and others revealed that they comprised four families: Tibeto-Burman, [[Tai languages|Tai]], [[Mon–Khmer languages|Mon–Khmer]] and [[Malayo-Polynesian languages|Malayo-Polynesian]]. [[Julius Klaproth]] had noted in 1823 that Burmese, Tibetan, and Chinese all shared common basic [[vocabulary]] but that [[Thai language|Thai]], [[Mon language|Mon]], and [[Vietnamese language|Vietnamese]] were quite different.{{sfnp|van Driem|2001|p=334}}{{sfnp|Klaproth|1823|pp=346, 363–365}} [[Ernst Kuhn]] envisaged a group with two branches, Chinese-Siamese and Tibeto-Burman.{{efn|{{harvp|Kuhn|1889|p=189}}: "wir das Tibetisch-Barmanische einerseits, das Chinesisch-Siamesische anderseits als deutlich geschiedene und doch wieder verwandte Gruppen einer einheitlichen Sprachfamilie anzuerkennen haben." (also quoted in {{harvp|van Driem|2001|p=264}}.)}} [[August Conrady]] called this group Indo-Chinese in his influential 1896 classification, though he had doubts about Karen. Conrady's terminology was widely used, but there was uncertainty regarding his exclusion of Vietnamese. [[Franz Nikolaus Finck]] in 1909 placed Karen as a third branch of Chinese-Siamese.{{sfnp|van Driem|2001|p=344}}{{sfnp|Finck|1909|p=57}}

[[Jean Przyluski]] introduced the French term ''sino-tibétain'' as the title of his chapter on the group in [[Antoine Meillet|Meillet]] and [[Marcel Cohen|Cohen]]'s ''Les langues du monde'' in 1924.{{sfnp|Przyluski|1924|p=361}}{{sfnp|Sapir|1925|p=373}} He divided them into three groups: Tibeto-Burman, Chinese and Tai,{{sfnp|Przyluski|1924|p=361}} and was uncertain about the affinity of Karen and [[Hmong–Mien]].{{sfnp|Przyluski|1924|p=380}} The English translation "Sino-Tibetan" first appeared in a short note by Przyluski and [[Gordon Luce|Luce]] in 1931.{{sfnp|Przyluski|Luce|1931}}

===Shafer and Benedict===
In 1935, the anthropologist [[Alfred Kroeber]] started the Sino-Tibetan Philology Project, funded by the [[Works Project Administration]] and based at the [[University of California, Berkeley]].{{sfnp|van Driem|2014|p=15}} The project was supervised by Robert Shafer until late 1938, and then by [[Paul K. Benedict]]. Under their direction, the staff of 30 non-linguists collated all the available documentation of Sino-Tibetan languages. The result was eight copies of a 15-volume typescript entitled ''Sino-Tibetan Linguistics''.{{sfnp|Hale|1982|p=4}}{{efn|The volumes were: 1. Introduction and bibliography, 2. Bhotish, 3. West Himalayish, 4. West Central Himalayish, 5. East Himalayish, 6. Digarish, 7. Nungish, 8. Dzorgaish, 9. Hruso, 10. Dhimalish, 11. Baric, 12. Burmish–Lolish, 13. Kachinish, 14. Kukish, 15. Mruish.{{sfnp|Miller|1974|p=195}}}} This work was never published, but furnished the data for a series of papers by Shafer, as well as Shafer's five-volume ''Introduction to Sino-Tibetan'' and Benedict's ''Sino-Tibetan, a Conspectus''.{{sfnp|Miller|1974|pp=195–196}}{{sfnp|Benedict|1972|p=v}}

Benedict completed the manuscript of his work in 1941, but it was not published until 1972.{{sfnp|Matisoff|1991|p=473}} Instead of building the entire family tree, he set out to reconstruct a [[Proto-Tibeto-Burman language]] by comparing five major languages, with occasional comparisons with other languages.{{sfnp|Handel|2008|p=434}} He reconstructed a two-way distinction on initial consonants based on voicing, with aspiration conditioned by pre-initial consonants that had been retained in Tibetic but lost in many other languages.{{sfnp|Benedict|1972|pp=20–21}} Thus, Benedict reconstructed the following initials:{{sfnp|Benedict|1972|pp=17–18, 133–139, 164–171}}

Although the initial consonants of cognates tend to have the same [[place of articulation|place]] and [[manner of articulation]], voicing and aspiration are often unpredictable.{{sfnp|Handel|2008|pp=425–426}} This irregularity was attacked by [[Roy Andrew Miller]],{{sfnp|Miller|1974|p=197}} though Benedict's supporters attribute it to the effects of prefixes that have been lost and are often unrecoverable.{{sfnp|Matisoff|2003|p=16}} The issue remains unsolved today.{{sfnp|Handel|2008|pp=425–426}} It was cited together with the lack of reconstructable shared morphology, and evidence that much shared lexical material has been borrowed from [[Chinese language|Chinese]] into [[Tibeto-Burman]], by [[Christopher Beckwith]], one of the few scholars still arguing that Chinese is not related to Tibeto-Burman.{{sfnp|Beckwith|1996}}{{sfnp|Beckwith|2002b}}

Benedict also reconstructed, at least for Tibeto-Burman, prefixes such as the [[causative]] ''s-'', the [[intransitive]] ''m-'', and ''r-'', ''b-'' ''g-'' and ''d-'' of uncertain function, as well as suffixes ''-s'', ''-t'' and ''-n''.{{sfnp|Benedict|1972|pp=98–123}}

===Study of literary languages===
[[File:Kǒngzǐ Shīlùn Manuscript from Shanghai Museum 1.jpg|thumb|right|upright|Ancient Chinese text on [[bamboo strips]]]]
[[Old Chinese]] is by far the oldest recorded Sino-Tibetan language, with inscriptions dating from around 1250 BC and a huge body of literature from the first millennium BC. However, the Chinese script is logographic and does not represent sounds systematically; it is therefore difficult to reconstruct the phonology of the language from the written records. Scholars have sought to reconstruct the [[phonology of Old Chinese]] by comparing the obscure descriptions of the sounds of [[Middle Chinese]] in medieval dictionaries with phonetic elements in [[Chinese characters]] and the rhyming patterns of early poetry. The first complete reconstruction, the ''[[Grammata Serica Recensa]]'' of [[Bernard Karlgren]], was used by Benedict and Shafer.{{sfnp|Matisoff|1991|pp=471–472}}

Karlgren's reconstruction was somewhat unwieldy, with many sounds having a highly non-uniform distribution. Later scholars have revised it by drawing on a range of other sources.{{sfnp|Norman|1988|p=45}} Some proposals were based on cognates in other Sino-Tibetan languages, though workers have also found solely Chinese evidence for them.{{sfnp|Baxter|1992|pp=25–26}} For example, recent [[reconstructions of Old Chinese]] have reduced Karlgren's 15 vowels to a six-vowel system originally suggested by [[Nicholas Bodman]].{{sfnp|Bodman|1980|p=47}} Similarly, Karlgren's *l has been recast as *r, with a different initial interpreted as *l, matching Tibeto-Burman cognates, but also supported by Chinese transcriptions of foreign names.{{sfnp|Baxter|1992|pp=197, 199–202}} A growing number of scholars believe that Old Chinese did not use tones and that the tones of Middle Chinese developed from final consonants. One of these, *-s, is believed to be a suffix, with cognates in other Sino-Tibetan languages.{{sfnp|Baxter|1992|pp=315–317}}

[[File:Turfan fragment tibt.jpg|thumb|left|[[Old Tibetan]] text found at [[Turfan]]]]
[[Tibetic languages|Tibetic]] has extensive written records from the adoption of writing by the [[Tibetan Empire]] in the mid-7th century. The earliest records of [[Burmese language|Burmese]] (such as the 12th-century [[Myazedi inscription]]) are more limited, but later an extensive literature developed. Both languages are recorded in alphabetic scripts ultimately derived from the [[Brahmi script]] of Ancient India. Most comparative work has used the conservative written forms of these languages, following the dictionaries of [[Heinrich August Jäschke|Jäschke]] (Tibetan) and [[Adoniram Judson|Judson]] (Burmese), though both contain entries from a wide range of periods.{{sfnp|Beckwith|2002a|pp=xiii–xiv}}

There are also extensive records in [[Tangut language|Tangut]], the language of the [[Western Xia]] (1038–1227). Tangut is recorded in a Chinese-inspired logographic script, whose interpretation presents many difficulties, even though multilingual dictionaries have been found.{{sfnp|Thurgood|2003|p=17}}{{sfnp|Hill|2015}}

[[Gong Hwang-cherng]] has compared Old Chinese, Tibetic, Burmese, and Tangut to establish sound correspondences between those languages.{{sfnp|Handel|2008|p=434}}{{sfnp|Gong|1980}} He found that Tibetic and Burmese {{IPA|/a/}} correspond to two Old Chinese vowels, *a and *ə.{{sfnp|Handel|2008|p=431}} While this has been considered evidence for a separate Tibeto-Burman subgroup, Hill (2014) finds that Burmese has distinct correspondences for Old Chinese rhymes ''-ay'' : *-aj and ''-i'' : *-əj, and hence argues that the development *ə > *a occurred independently in Tibetan and Burmese.{{sfnp|Hill|2014|pp=97–104}}

===Fieldwork===
The descriptions of non-literary languages used by Shafer and Benedict were often produced by missionaries and colonial administrators of varying linguistic skills.{{sfnp|Matisoff|1991|pp=472–473}}{{sfnp|Hale|1982|pp=4–5}} Most of the smaller Sino-Tibetan languages are spoken in inaccessible mountainous areas, many of which are politically or militarily sensitive and thus closed to investigators. Until the 1980s, the best-studied areas were [[Nepal]] and northern [[Thailand]].{{sfnp|Matisoff|1991|pp=470, 476–478}} In the 1980s and 1990s, new surveys were published from the Himalayas and southwestern China. Of particular interest was the increasing literature on the [[Qiangic languages]] of western [[Sichuan]] and adjacent areas.{{sfnp|Handel|2008|p=435}}{{sfnp|Matisoff|1991|p=482}}

==Distribution==

Most of the current spread of Sino-Tibetan languages is the result of historical expansions of the three groups with the most speakers – Chinese, Burmese and Tibetic – replacing an unknown number of earlier languages. These groups also have the longest literary traditions of the family. The remaining languages are spoken in mountainous areas, along the southern slopes of the [[Himalayas]], the [[Southeast Asian Massif]] and the eastern edge of the [[Tibetan Plateau]].

===Contemporary languages===
The branch with the largest number of speakers by far is the [[Sinitic languages]], with 1.3 billion speakers, most of whom live in the eastern half of China.{{sfnp|Eberhard|Simons|Fennig|2019|loc="Chinese"}} The first records of Chinese are [[oracle bone]] inscriptions from {{Circa|1250 BC}}, when [[Old Chinese]] was spoken around the middle reaches of the [[Yellow River]].{{sfnp|Norman|1988|p=4}} Chinese has since expanded throughout China, forming a family whose diversity has been compared with the [[Romance languages]]. Diversity is greater in the rugged terrain of southeast China than in the [[North China Plain]].{{sfnp|Norman|1988|pp=187–188}}

[[Burmese language|Burmese]] is the national language of [[Myanmar]], and the first language of some 33 million people.{{sfnp|Eberhard|Simons|Fennig|2019|loc="Burmese"}} Burmese speakers first entered the northern [[Irrawaddy River|Irrawaddy]] basin from what is now western [[Yunnan]] in the early ninth century, in conjunction with an invasion by [[Nanzhao]] that shattered the [[Pyu city-states]].{{sfnp|Taylor|1992|p=165}} Other [[Burmish languages]] are still spoken in [[Dehong Prefecture]] in the far west of Yunnan.{{sfnp|Wheatley|2003|p=195}} By the 11th century, their [[Pagan Kingdom]] had expanded over the whole basin.{{sfnp|Taylor|1992|p=165}} The oldest texts, such as the [[Myazedi inscription]], date from the early 12th century.{{sfnp|Wheatley|2003|p=195}} The closely related [[Loloish languages]] are spoken by 9 million people in the mountains of western Sichuan, Yunnan, and nearby areas in northern Myanmar, Thailand, Laos, and Vietnam.{{sfnp|Thurgood|2003|pp=8–9}}{{sfnp|Eberhard|Simons|Fennig|2019}}

The [[Tibetic languages]] are spoken by some 6 million people on the [[Tibetan Plateau]] and neighbouring areas in the [[Himalayas]] and western [[Sichuan]].{{sfnp|Tournadre|2014|p=117}} They are descended from [[Old Tibetan]], which was originally spoken in the [[Yarlung Valley]] before it was spread by the expansion of the [[Tibetan Empire]] in the seventh century.{{sfnp|Tournadre|2014|p=107}} Although the empire collapsed in the ninth century, [[Classical Tibetan]] remained influential as the liturgical language of [[Tibetan Buddhism]].{{sfnp|Tournadre|2014|p=120}}

The remaining languages are spoken in upland areas. Southernmost are the [[Karen languages]], spoken by 4 million people in the hill country along the Myanmar–Thailand border, with the greatest diversity in the [[Karen Hills]], which are believed to be the homeland of the group.{{sfnp|Thurgood|2003|p=18}} The highlands stretching from northeast India to northern Myanmar contain over 100 highly diverse Sino-Tibetan languages. Other Sino-Tibetan languages are found along the southern slopes of the [[Himalayas]] and the eastern edge of the Tibetan plateau.{{sfnp|Handel|2008|pp=424–425}}
The 22 official languages listed in the [[Eighth Schedule to the Constitution of India]] include only two Sino-Tibetan languages, namely [[Meitei language|Meitei]] (officially called Manipuri) and [[Bodo language|Bodo]].

===Homeland===
There has been a range of proposals for the Sino-Tibetan [[urheimat]], reflecting the uncertainty about the classification of the family and its time depth.{{sfnp|Handel|2008|p=423}} Three major hypotheses for the place and time of Sino-Tibetan unity have been presented:{{sfnp|Zhang|Yan|Pan|Jin|2019|p=112}}
* The most commonly cited hypothesis associates the family with the Neolithic [[Yangshao culture]] (7000–5000 years BP) of the [[Yellow River]] basin, with an expansion driven by [[millet]] agriculture.<ref>Archaeological evidence for initial migration of Neolithic Proto Sino-Tibetan speakers from Yellow River valley to Tibetan Plateau. Li Liua,, Jian Chen, Jiajing Wang, Yanan Zhao, and Xingcan Chen. Edited by Melinda Zeder, Smithsonian Institution, Frederick, MD; received July 12, 2022; accepted October 22, 2022. PNAS. https://www.pnas.org/doi/epdf/10.1073/pnas.2212006119</ref> This scenario is associated with a proposed primary split between [[Varieties of Chinese|Sinitic]] in the east and the [[Tibeto-Burman languages]], often assigned to the [[Majiayao culture]] (5300–4000 years BP) in the upper reaches of the Yellow River on the northeast edge of the [[Tibetan plateau]].{{sfnp|Zhang|Yan|Pan|Jin|2019|p=112}} For example, [[James Matisoff]] proposes a split around 6000 years BP, with Chinese-speakers settling along the Yellow River and other groups migrating south down the [[Yangtze]], [[Mekong]], [[Salween River|Salween]] and [[Brahmaputra River|Brahmaputra]] rivers.{{sfnp|Matisoff|1991|pp=470–471}}
* [[George van Driem]] proposes a Sino-Tibetan homeland in the [[Sichuan Basin]] before 9000 years BP, with an associated taxonomy reflecting various outward migrations over time, first into northeast India, and later north (the predecessors of Chinese and Tibetic) and south (Karen and Lolo–Burmese).{{sfnp|van Driem|2005|pp=91–95}}
* [[Roger Blench]] argues that agriculture cannot be reconstructed for Proto-Sino-Tibetan.{{sfnp|Blench|2009}} Blench and Mark Post have proposed that the earliest speakers of Sino-Tibetan were not farmers but highly diverse foragers in the eastern foothills of the [[Himalayas]] in [[Northeast India]], the area of greatest diversity, around 9000 years BP.{{sfnp|Blench|Post|2014|p=89}} They then envisage a series of migrations over the following millennia, with Sinitic representing one of the groups that migrated into China.{{sfnp|Blench|Post|2014|pp=90, 92}}
Zhang et al. (2019) performed a computational phylogenetic analysis of 109 Sino-Tibetan languages to suggest a Sino-Tibetan homeland in northern China near the Yellow River basin. The study further suggests that there was an initial major split between the Sinitic and Tibeto-Burman languages approximately 4,200 to 7,800 years ago (with an average of 5,900 years ago), associated with the Yangshao and/or Majiayao cultures.{{sfnp|Zhang|Yan|Pan|Jin|2019|p=112}} Sagart et al. (2019) performed another phylogenetic analysis based on different data and methods to arrive at the same conclusions to the homeland and divergence model but proposed an earlier root age of approximately 7,200 years ago, associating its origin with millet farmers of the late [[Cishan culture]] and early Yangshao culture.{{sfnp|Sagart|Jacques|Lai|Ryder|2019|pp=10319–10320}}

==Classification==
Several low-level branches of the family, particularly [[Lolo-Burmese languages|Lolo-Burmese]], have been securely reconstructed, but in the absence of a secure reconstruction of a Sino-Tibetan [[proto-language]], the higher-level structure of the family remains unclear.{{sfnp|Handel|2008|p=426}}{{sfnp|DeLancey|2009|p=695}} Thus, a conservative classification of Sino-Tibetan/Tibeto-Burman would posit several dozen small coordinate families and [[language isolate|isolates]]; attempts at subgrouping are either geographic conveniences or hypotheses for further research.{{citation needed|date=May 2024}}

===Li (1937)===
In a survey in the 1937 ''Chinese Yearbook'', [[Li Fang-Kuei]] described the family as consisting of four branches:{{sfnp|Li|1937|pp=60–63}}{{sfnp|Handel|2008|p=424}}

{{tree list}}
* Indo-Chinese (Sino-Tibetan)
** Chinese
** [[Tai languages|Tai]] (later expanded to [[Kam–Tai languages|Kam–Tai]])
** [[Hmong–Mien languages|Miao–Yao]] (Hmong–Mien)
** [[Tibeto-Burman]]
{{tree list/end}}

Tai and Miao–Yao were included because they shared [[isolating language|isolating]] typology, [[tone (linguistics)|tone]] systems and some vocabulary with Chinese. At the time, tone was considered so fundamental to language that tonal typology could be used as the basis for classification. In the Western scholarly community, these languages are no longer included in Sino-Tibetan, with the similarities attributed to diffusion across the [[Mainland Southeast Asia linguistic area]], especially since {{harvtxt|Benedict|1942}}.{{sfnp|Handel|2008|p=424}} The exclusions of Vietnamese by Kuhn and of Tai and Miao–Yao by Benedict were vindicated in 1954 when [[André-Georges Haudricourt]] demonstrated that the tones of Vietnamese were reflexes of final consonants from [[Proto-Mon–Khmer language|Proto-Mon–Khmer]].{{sfnp|Matisoff|1991|p=487}}

Many Chinese linguists continue to follow Li's classification.{{efn|See, for example, the "Sino-Tibetan" (汉藏语系 ''Hàn-Zàng yǔxì'') entry in the "languages" (語言文字, ''Yǔyán-Wénzì'') volume of the ''[[Encyclopedia of China]]'' (1988).}}{{sfnp|Handel|2008|p=424}} However, this arrangement remains problematic. For example, there is disagreement over whether to include the entire [[Kra–Dai languages|Kra–Dai]] family or just [[Kam–Tai languages|Kam–Tai]] (Zhuang–Dong excludes the [[Kra languages]]), because the Chinese cognates that form the basis of the putative relationship are not found in all branches of the family and have not been reconstructed for the family as a whole. In addition, Kam–Tai itself no longer appears to be a valid node within Kra–Dai.

===Benedict (1942)===
Benedict overtly excluded Vietnamese (placing it in Mon–Khmer) as well as [[Hmong–Mien languages|Hmong–Mien]] and [[Kra–Dai languages|Kra–Dai]] (placing them in [[Austro-Tai languages|Austro-Tai]]). He otherwise retained the outlines of Conrady's Indo-Chinese classification, though putting [[Karen languages|Karen]] in an intermediate position:{{sfnp|Benedict|1942|p=600}}{{sfnp|Benedict|1972|pp=2–4}}

{{tree list}}
* Sino-Tibetan
** Chinese
** Tibeto-Karen
*** Karen
*** Tibeto-Burman
{{tree list/end}}

===Shafer (1955)===
Shafer criticized the division of the family into [[Tibeto-Burman languages|Tibeto-Burman]] and Sino-Daic branches, which he attributed to the different groups of languages studied by Konow and other scholars in [[British India]] on the one hand and by [[Henri Maspero]] and other French linguists on the other.{{sfnp|Shafer|1955|pp=94–96}} He proposed a detailed classification, with six top-level divisions:{{sfnp|Shafer|1955|pp=99–108}}{{sfnp|Shafer|1966|p=1}}{{efn|For Shafer, the suffix "-ic" denoted a primary division of the family, whereas the suffix "-ish" denoted a sub-division of one of those.}}

{{tree list}}
* Sino-Tibetan
** Sinitic
** Daic
** Bodic
** Burmic
** [[Bodo–Garo languages|Baric]]
** Karenic
{{tree list/end}}

Shafer was sceptical of the inclusion of Daic, but after meeting Maspero in Paris decided to retain it pending a definitive resolution of the question.{{sfnp|Shafer|1955|pp=97–99}}{{sfnp|van Driem|2001|pp=343–344}}

===Matisoff (1978, 2015)===
[[James Matisoff]] abandoned Benedict's Tibeto-Karen hypothesis:

{{tree list}}
* Sino-Tibetan
** Chinese
** Tibeto-Burman
{{tree list/end}}

Some more-recent Western scholars, such as Bradley (1997) and La Polla (2003), have retained Matisoff's two primary branches, though differing in the details of Tibeto-Burman. However, Jacques (2006) notes, "comparative work has never been able to put forth evidence for common innovations to all the Tibeto-Burman languages (the Sino-Tibetan languages to the exclusion of Chinese)"{{efn|les travaux de comparatisme n'ont jamais pu mettre en évidence l'existence d'innovations communes à toutes les langues « tibéto-birmanes » (les langues sino-tibétaines à l'exclusion du chinois)}} and that "it no longer seems justified to treat Chinese as the first branching of the Sino-Tibetan family,"{{efn|il ne semble plus justifié de traiter le chinois comme le premier embranchement primaire de la famille sino-tibétaine}} because the morphological divide between Chinese and Tibeto-Burman has been bridged by recent reconstructions of [[Old Chinese]].

The internal structure of Sino-Tibetan has been tentatively revised as the following [[Stammbaum]] by Matisoff in the final print release of the ''[[Sino-Tibetan Etymological Dictionary and Thesaurus]]'' (STEDT) in 2015.{{sfnp|Matisoff|2015|pp=xxxii, 1123–1127}} Matisoff acknowledges that the position of Chinese within the family remains an open question.{{sfnp|Matisoff|2015|p=xxxi}}

===Starostin (1996)===
Sergei Starostin proposed that both the [[Kiranti languages]] and Chinese are divergent from a "core" Tibeto-Burman of at least Bodish, Lolo-Burmese, Tamangic, Jinghpaw, Kukish, and Karen (other families were not analysed) in a hypothesis called ''Sino-Kiranti''. The proposal takes two forms: that Sinitic and Kiranti are themselves a valid node or that the two are not demonstrably close so that Sino-Tibetan has three primary branches:

{{tree list}}
* Sino-Tibetan (version 1)
** Sino-Kiranti
** Tibeto-Burman
* Sino-Tibetan (version 2)
** Chinese
** Kiranti
** Tibeto-Burman
{{tree list/end}}

===Van Driem (1997, 2001)===
[[George van Driem]], like Shafer, rejects a primary split between Chinese and the rest, suggesting that Chinese owes its traditional privileged place in Sino-Tibetan to historical, typological, and cultural, rather than linguistic, criteria. He calls the entire family "Tibeto-Burman", a name he says has historical primacy,{{sfnp|van Driem|2001|p=383}} but other linguists who reject a privileged position for Chinese nevertheless continue to call the resulting family "Sino-Tibetan".

Like Matisoff, van Driem acknowledges that the relationships of the [[Kuki-Naga languages|"Kuki–Naga" languages]] ([[Kukish languages|Kuki]], [[Mizo language|Mizo]], [[Meitei language|Meitei]], etc.), both amongst each other and to the other languages of the family, remain unclear. However, rather than placing them in a geographic grouping, as Matisoff does, van Driem leaves them unclassified. He has proposed several hypotheses, including the reclassification of Chinese to a Sino-Bodic subgroup:

{{tree list}}
*Tibeto-Burman
** Western (Baric, Brahmaputran, or [[Sal languages|Sal]]): [[Dhimal languages|Dhimal]], [[Bodo–Garo languages|Bodo–Garo]], [[Konyak languages|Konyak]], [[Kachin–Luic languages|Kachin–Luic]]
** Eastern
*** Northern (Sino-Bodic)
**** Northwestern (Bodic): [[Bodish languages|Bodish]], [[Kiranti languages|Kirantic]], [[West Himalayish languages|West Himalayish]], [[Tamangic languages|Tamangic]] and several isolates
**** Northeastern ([[Sinitic languages|Sinitic]])
*** Southern
**** Southwestern: [[Lolo-Burmese languages|Lolo-Burmese]], [[Karen languages|Karenic]]
**** Southeastern: [[Qiangic languages|Qiangic]], [[Jiarongic languages|Jiarongic]]
**Some other small families and isolates as primary branches ([[Newar language|Newar]], [[Nungish languages|Nungish]], [[Magaric languages|Magaric]], ''etc.'')
{{tree end}}

Van Driem points to two main pieces of evidence establishing a special relationship between Sinitic and Bodic and thus placing Chinese within the Tibeto-Burman family. First, there are some parallels between the morphology of [[Old Chinese]] and the modern Bodic languages. Second, there is a body of lexical cognates between the Chinese and Bodic languages, represented by the Kirantic language [[Limbu language|Limbu]].{{sfnp|van Driem|1997}}

In response, Matisoff notes that the existence of shared lexical material only serves to establish an absolute relationship between two language families, not their relative relationship to one another. Although some cognate sets presented by van Driem are confined to Chinese and Bodic, many others are found in Sino-Tibetan languages generally and thus do not serve as evidence for a special relationship between Chinese and Bodic.{{sfnp|Matisoff|2000}}

===Van Driem's  "fallen leaves" model (2001, 2014)===
Van Driem has also proposed a "fallen leaves" model that lists dozens of well-established low-level groups while remaining agnostic about intermediate groupings of these.{{sfnp|van Driem|2001|p=403}} In the most recent version (van Driem 2014), 42 groups are identified (with individual languages highlighted in ''italics''):{{sfnp|van Driem|2014|p=19}}

{{div col end}}

He also suggested (van Driem 2007) that the Sino-Tibetan language family be renamed "Trans-Himalayan", which he considers to be more neutral.{{sfnp|van Driem|2007|p=226}}

Orlandi (2021) also considers the van Driem's Trans-Himalayan fallen leaves model to be more plausible than the bifurcate classification of Sino-Tibetan being split into Sinitic and Tibeto-Burman.<ref>{{cite journal |last=Orlandi |first=Georg |date=2021 |title=Once again on the history and validity of the Sino-Tibetan bifurcate model |url=https://jolr.ru/index.php?article=310 |journal=[[Journal of Language Relationship]] |volume=19 |issue=3–4 |pages=263–292}}</ref>

===Blench and Post (2014)===
[[Roger Blench]] and Mark W. Post have criticized the applicability of conventional Sino-Tibetan classification schemes to minor languages lacking an extensive written history (unlike Chinese, Tibetic, and Burmese). They find that the evidence for the subclassification or even ST affiliation in all of several minor languages of northeastern India, in particular, is either poor or absent altogether.
{{blockquote|While relatively little has been known about the languages of this region up to and including the present time, this has not stopped scholars from proposing that these languages either constitute or fall within some other Tibeto-Burman subgroup. However, in the absence of any sort of systematic comparison – whether the data are thought reliable or not – such "subgroupings" are essentially vacuous. The use of pseudo-genetic labels such as "Himalayish" and "Kamarupan" inevitably gives an impression of coherence which is at best misleading.|{{harvtxt|Blench|Post|2014}}, p. 3}}
In their view, many such languages would for now be best considered unclassified, or "internal isolates" within the family. They propose a provisional classification of the remaining languages:

{{tree list}}
*Sino-Tibetan

***{{tree list/branching}}
****Western: [[Gongduk language|Gongduk]], [['Ole language|'Ole]], [[Mahakiranti languages|Mahakiranti]], [[Lepcha language|Lepcha]], [[Magaric languages|Kham–Magaric–Chepang]], [[Tamangic languages|Tamangic]], and [[Lhokpu language|Lhokpu]]

******[[Lolo-Burmese languages|Lolo-Burmese]]–[[Naic languages|Naic]]
******[[Bodish languages|Bodish]]
*****[[Nungish languages|Nungish]]
{{tree list/end}}

Following that, because they propose that the three best-known branches may be much closer related to each other than they are to "minor" Sino-Tibetan languages, Blench and Post argue that "Sino-Tibetan" or "Tibeto-Burman" are inappropriate names for a family whose earliest divergences led to different languages altogether. They support the proposed name "Trans-Himalayan".

==Typology==
===Word order===
Except for the Chinese, [[Macro-Bai languages|Bai]], [[Karenic languages|Karenic]], and [[Mruic languages|Mruic]] languages, the usual word order in Sino-Tibetan languages is [[subject–object–verb|object–verb]].{{sfnp|Dryer|2003|p=43}} However, Chinese and Bai differ from almost all other [[subject–verb–object]] languages in the world in placing relative clauses before the nouns they modify.{{sfnp|Dryer|2003|pp=50}} Most scholars believe SOV to be the original order, with Chinese, Karen, and Bai having acquired SVO order due to the influence of neighbouring languages in the [[Mainland Southeast Asia linguistic area]].{{sfnp|Dryer|2003|pp=43–45}}<ref>{{cite journal|author=Charles N. Li & Sandra A. Thompson|title=An explanation of word order change SVO > SOV|year=1974|journal=Foundations of Language|volume=12|pages=201–214}}</ref> This has been criticized as being insufficiently corroborated by Djamouri et al. 2007, who instead reconstruct a VO order for Proto-Sino-Tibetan.<ref>{{cite journal |given1=Redouane |surname1=Djamouri |given2=Wautraud |surname2=Paul |given3=John |surname3=Whitman |year=2007 |title=Reconstructing VO constituent order for proto-Sino-Tibetan |journal=8th International Conference on Historical Linguistics}}</ref>

===Phonology===
Contrastive [[Tone (linguistics)|tones]] are a feature found across the family although absent in some languages like [[Purgi language|Purik]].{{sfn|Benedict|1972|p=85}} [[Phonation]] contrasts are also present among many, notably in the [[Lolo-Burmese languages|Lolo-Burmese]] group.{{sfn|Matisoff|2003|p=241}} While Benedict contended that [[Proto-Tibeto-Burman language|Proto-Tibeto-Burman]] would have a two-tone system, Matisoff refrained from reconstructing it since tones in individual languages may have developed independently through the process of [[Tone (linguistics)#Origin and developmen|tonogenesis]].{{sfn|Matisoff|2003|p=12}}

===Morphology===
====The structure of words====
Sino-Tibetan is structurally one of the most diverse language families in the world, including all of the gradation of morphological complexity from isolating ([[Lolo-Burmese languages|Lolo-Burmese]], [[Tujia language|Tujia]]) to polysynthetic ([[Gyalrongic languages|Gyalrongic]], [[Kiranti languages|Kiranti]]) languages.{{sfnp|Sagart|Jacques|Lai|Ryder|2019|pp=10319–10320}} While [[Sinitic languages|Sinitic]] languages are normally taken to be a prototypical example of the [[Isolating language|isolating]] morphological type, southern Chinese languages express this trait far more strongly than northern Chinese languages do.<ref>{{Cite web|last1=Arcodia|first1=Giorgio Francesco|last2=Basciano|first2=Bianca|date=2020-01-30|title=Morphology in Sino-Tibetan Languages|url=https://oxfordre.com/linguistics/oso/viewentry/10.1093$002facrefore$002f9780199384655.001.0001$002facrefore-9780199384655-e-530|access-date=2021-11-26|website=Oxford Research Encyclopedia of Linguistics|doi=10.1093/acrefore/9780199384655.013.530|isbn=978-0-19-938465-5|language=en}}</ref>

====Voice and Voicing alternation====
Initial consonant [[Alternation (linguistics)|alternations]] related to [[Transitivity (grammar)|transitivity]] are pervasive in Sino-Tibetan; while devoicing (or aspiration) of the initial is associated with a transitive/[[causative]] verb, voicing is linked to its intransitive/[[anticausative]] counterpart.{{sfnp|LaPolla|2003|pp=23}}{{sfn | Shuya | Jacques | Yunfan | 2019 | p=74}} This is argued to reflect [[morphological derivation]]s that existed in earlier stages of the family. Even in Chinese, one would find semantically-related pairs of verbs such as 見 'to see' ([[Middle Chinese|MC]]: ''kenH'') and 現 'to appear' (''ɣenH''), which are respectively reconstructed as ''*[k]ˤen-s'' and ''*N-[k]ˤen-s'' in the Baxter-Sagart system of [[Old Chinese]].{{sfn | Shuya | Jacques | Yunfan | 2019 | p=74}}{{sfn | Baxter | Sagart| 2014 | p=54}}

====Ergativity====
In [[morphosyntactic alignment]], many Tibeto-Burman languages have [[ergative case|ergative]] and/or [[anti-ergative]] (an argument that is not an actor) case marking. However, the anti-ergative case markings can not be reconstructed at higher levels in the family and are thought to be innovations.{{sfnp|LaPolla|2003|pp=34–35}}

====Person indexation====
Many Sino-Tibetan languages exhibit a system of person indexation.{{sfn|Jacques|Pellard|2022|p=2}} Notably, [[Gyalrongic languages|Gyalrongic]] and [[Kiranti languages|Kiranti]] have an [[Direct–inverse alignment|inverse]] marker prefixed to a transitive verb when the agent is lower than the patient in a certain person hierarchy.{{sfn|Jacques|Pellard|2022|pp=3-4}}

Hodgson had in 1849 noted a dichotomy between "pronominalized" ([[Synthetic language|inflecting]]) languages, stretching across the [[Himalaya]]s from [[Himachal Pradesh]] to eastern [[Nepal]], and "non-pronominalized" ([[isolating language|isolating]]) languages. Konow (1909) explained the pronominalized languages as due to a [[Munda languages|Munda]] [[Substrata (linguistics)|substratum]], with the idea that Indo-Chinese languages were essentially isolating as well as tonal. Maspero later attributed the putative substratum to [[Indo-Aryan languages|Indo-Aryan]]. It was not until Benedict that the inflectional systems of these languages were recognized as (partially) native to the family. Scholars disagree over the extent to which the agreement system in the various languages can be reconstructed for the [[proto-language]].{{sfnp|Handel|2008|p=430}}{{sfnp|LaPolla|2003|pp=29–32}}

===Evidentiality, mirativity, and egophoricity===
Although not very common in some families and [[Sprachbund|linguistic areas]] like [[Standard Average European]], fairly complex systems of [[evidentiality]] (grammatical marking of information source) are found in many [[Tibeto-Burman languages]].{{sfn|Aikhenvald|LaPolla|2007|p=3}} The family has also contributed to the study of [[mirativity]]{{sfn|DeLancey|1997}}{{sfn|Aikhenvald|LaPolla|2007|p=11}} and [[egophoricity]],{{sfn | San Roque | Floyd | Norcliffe | 2018 | pp=5-6}} which are relatively new concepts in [[linguistic typology]].

==Proposed external relationships==
Beyond the traditionally recognized families of Southeast Asia, some [[Classification schemes for Southeast Asian languages|possible broader relationships]] have been suggested.

===Austronesian===
{{main|Sino-Austronesian languages}}
Laurent Sagart proposes a "Sino-Austronesian" family with Sino-Tibetan and [[Austronesian languages|Austronesian]] (including [[Kra–Dai languages|Kra–Dai]] as a [[Austro-Tai languages|subbranch]]) as primary branches. [[Stanley Starosta]] has extended this proposal with a further branch called "Yangzian" joining Hmong–Mien and Austroasiatic. The proposal has been largely rejected by other linguists who argue that the similarities between Austronesian and Sino-Tibetan more likely arose from contact rather than being genetic.<ref name="Li 1995">{{cite book |surname=Li |given=Paul Jenkuei |title=The Ancestry of the Chinese Language |publisher=Chinese University Press |year=1995 |editor-surname=Wang |editor-given=William S-Y. |series=''Journal of Chinese Linguistics'' Monograph Series |volume=8 |pages=92–112 |chapter=Is Chinese genetically related to Austronesian? |jstor=23826144 |issue=8}}</ref><ref name="Blust 2009">{{cite book |surname=Blust |given=Robert |title=The Ancestry of the Chinese Language |publisher=Chinese University Press |year=1995 |editor-surname=Wang |editor-given=William S-Y. |series=''Journal of Chinese Linguistics'' Monograph Series |volume=8 |pages=283–298 |chapter=An Austronesianist looks at Sino-Austronesian |jstor=23826144 |issue=8}}</ref><ref name="Vovin 1997">{{cite journal |year=1997 |title=The comparative method and ventures beyond Sino-Tibetan |journal=Journal of Chinese Linguistics |volume=25 |pages=308–336 |jstor=23756693 |given=Alexander |surname=Vovin |number=2}}</ref>

The "[[Sino-Caucasian]]" hypothesis of [[Sergei Starostin]] posits that the [[Yeniseian languages]] form a [[clade]] with Sino-Tibetan, which he called '''Sino-Yeniseian'''. The Sino-Caucasian hypothesis has been expanded by others to "[[Dené–Caucasian languages|Dené–Caucasian]]" to include the [[Na-Dené languages]] of North America, [[Burushaski language|Burushaski]], [[Basque language|Basque]] and, occasionally, [[Etruscan language|Etruscan]]. A narrower binary [[Dené–Yeniseian]] family has recently been well received. The validity of the rest of the family, however, is viewed as doubtful or rejected by nearly all [[Historical linguistics|historical linguists]].<ref>[[Ives Goddard|Goddard, Ives]] (1996).

A link between the Na–Dené languages and Sino-Tibetan languages, known as '''Sino–Dené''' had also been proposed by [[Edward Sapir]]. Around 1920 Sapir became convinced that Na-Dené was more closely related to Sino-Tibetan than to other American families.<ref>{{Cite journal |last=Ruhlen |first=Merritt |date=1998-11-10 |title=The origin of the Na-Dene |journal=Proceedings of the National Academy of Sciences |language=en |volume=95 |issue=23 |pages=13994–13996 |bibcode=1998PNAS...9513994R |doi=10.1073/pnas.95.23.13994 |issn=0027-8424 |pmc=25007 |pmid=9811914 |doi-access=free}}</ref> Edward Vadja's Dené–Yeniseian proposal renewed interest among linguists such as [[Geoffrey Caveney]] (2014) to look into support for the Sino–Dené hypothesis. Caveney considered a link between Sino-Tibetan, Na-Dené, and Yeniseian to be plausible but did not support the hypothesis that Sino-Tibetan and Na-Dené were related to the Caucasian languages (Sino–Caucasian and Dené–Caucasian).<ref>{{Cite journal |last=Caveney |first=Geoffrey |date=2014 |title=Sino-Tibetan ŋ- and Na-Dene *kw- / *gw- / *xw-: 1st Person Pronouns and Lexical Cognate Sets |journal=Journal of Chinese Linguistics |volume=42 |issue=2 |pages=461–487 |jstor=24774894}}</ref>

A 2023 analysis by [[David Bradley (linguist)|David Bradley]] using the standard techniques of comparative linguistics supports a distant genetic link between the Sino-Tibetan, Na-Dené, and Yeniseian language families. Bradley argues that any similarities Sino-Tibetan shares with other language families of the East Asia area such as Hmong-Mien, [[Altaic languages|Altaic]] (which is a [[sprachbund]]), Austroasiatic, Kra–Dai, Austronesian came through contact; but as there has been no recent contact between the Sino-Tibetan, Na-Dené, and Yeniseian language families, any similarities these groups share must be residual.<ref>{{Cite journal |last=Bradley |first=David |date=2023-07-24 |title=Ancient Connections of Sinitic |journal=Languages |language=en |volume=8 |issue=3 |pages=176 |doi=10.3390/languages8030176 |issn=2226-471X |doi-access=free}}</ref>

===Indo-European===
{{Further|Indo-European languages}}

August Conrad proposed the Sino-Tibetan-Indo-European language family.{{citation needed|date=January 2024}} This hypothesis holds that there is a genetic relationship between the Sino-Tibetan language family and the Indo-European language family. The earliest comparative linguistic study of Chinese and Indo-European languages was by the 18th-century Nordic scholar [[Olaus Rudbeck]]. He compared the vocabulary of Gothic and Chinese and guessed that the two may be of the same origin. In the second half of the 19th century, Kong Haogu, Shigude, Ijosser, etc. successively proposed that Chinese and European languages are homologous. Among them, Kong Haogu, through the comparison of Chinese and Indo-European domestic animal vocabulary, first proposed an Indo-Chinese language macrofamily (including Chinese, Tibetan, Burmese, and Indo-European languages).

In the 20th century, R. Shafer put forward the conjecture of a Eurasial language super-family and listed hundreds of similar words between Tibeto-Burman and Indo-European languages.<ref>R. Shafer. Eurasial. Orbis. 1963, 12: 19–14.</ref><ref>R. Shafer. The Eurasial Linguistic Superfamily. Anthropos. 1965, 60: 1965.</ref>
