The '''Kra–Dai languages''' ({{IPAc-en|'|k|r|ɑː|.|d|aɪ}} {{respell|KRAH|dy}}, also known as '''Tai–Kadai''' {{IPAc-en|'|t|ai|.|k|@|,|d|aɪ}} {{respell|TIE|kə|DYE}} and '''Daic''' {{IPAc-en|'|d|ai|.|I|k}} {{respell|DYE|ik}}), are a [[Social:Language family|language family]] in [[Place:Mainland Southeast Asia|mainland Southeast Asia]], southern China, and northeastern India. All languages in the family are tonal, including [[Social:Thai language|Thai]] and [[Social:Lao language|Lao]], the national languages of Thailand and Laos, respectively.<ref>Diller, Anthony, Jerry Edmondson, Yongxian Luo.

==Names==
The name "Kra–Dai" was proposed by Weera Ostapirat (2000), as Kra and Dai are the reconstructed [[Social:Exonym and endonym|autonyms]] of the Kra and Tai branches, respectively.<ref name=Ostapirat2000 /> "Kra–Dai" has since been used by the majority of specialists working on Southeast Asian linguistics, including Norquest (2007),<ref name=norquest /> Pittayaporn (2009),<ref name=pittayaporn>Pittayaporn, Pittayawat. 2009.

The name "Tai–Kadai" is used in many references, as well as ''[[Social:Ethnologue|Ethnologue]]'' and ''[[Social:Glottolog|Glottolog]]'', but Ostapirat (2000) and others suggest that it is problematic and confusing, preferring the name "Kra–Dai" instead.<ref name="Ostapirat2000">Ostapirat, Weera. (2000). "[http://sealang.net/sala/archives/pdf8/weera2000proto.pdf Proto-Kra]." ''Linguistics of the Tibeto-Burman Area'' '''23''' (1): 1–251.</ref> "Tai–Kadai" comes from an obsolete bifurcation of the family into two branches, Tai and Kadai, which had first been proposed by Paul K. Benedict (1942).<ref name="Benedict1942"/> In 1942, Benedict placed three Kra languages ([[Social:Gelao languages|Gelao]], Laqua ([[Social:Qabiao language|Qabiao]]), and [[Social:Lachi language|Lachi]]) together with [[Social:Hlai languages|Hlai]] in a group that he called "Kadai", from ''ka'', meaning "person" in Gelao and Laqua and ''dai'', a form of a Hlai autonym.<ref name="Benedict1942">{{cite journal| first = Paul K. | last = Benedict |  title = Thai, Kadai, and Indonesian: A New Alignment in Southeastern Asia| journal = American Anthropologist | year = 1942 | volume = 44 | issue = 4 | pages = 576–601| jstor = 663309 | doi = 10.1525/aa.1942.44.4.02a00040 | doi-access = free }}</ref> Benedict's (1942) "Kadai" group was based on his observation that Kra and Hlai languages have [[Social:Austronesian languages|Austronesian]]-like numerals. However, this classification is now universally rejected as obsolete after Ostapirat (2000) demonstrated the coherence of the Kra branch, which does not subgroup with the Hlai branch as Benedict (1942) had proposed. "Kadai" is sometimes used to refer to the entire Kra–Dai family, including by Solnit (1988).<ref name="Solnit1988">Solnit, David B. 1988. "The position of Lakkia within Kadai."

Dallas: Summer Institute of Linguistics and the University of Texas at Arlington.</ref><ref name=edmondson1988 /> Adding to the confusion, some other references{which|date=February 2024}} restrict the usage of "Kadai" to only the Kra branch of the family.

The name "Daic" is used by Roger Blench (2008).<ref>Blench, Roger. 2008.

==Origin==

James R. Chamberlain (2016) proposes that the Tai-Kadai (Kra-Dai) language family was formed as early as the 12th century BCE in the middle of the Yangtze basin, coinciding roughly with the establishment of the Chu fiefdom and the beginning of the Zhou dynasty.<ref name="Chamberlain-Kra-Dai">Chamberlain, James R. (2016). "[https://www.academia.edu/26296118/Kra-Dai_and_the_Proto-History_of_South_China_and_Vietnam Kra-Dai and the Proto-History of South China and Vietnam]", pp. 27–77. In ''Journal of the Siam Society'', Vol. 104, 2016.</ref> The high diversity of Kra–Dai languages in Southern China, especially in Guizhou and Hainan, points to an origin of the Kra–Dai language family in Southern China, founding the nations that later became Thailand and Laos in what had been [[Social:Austroasiatic languages|Austroasiatic]] territory. Genetic and linguistic analyses show great homogeneity among Kra–Dai-speaking people in Thailand.<ref>{{Cite journal|last1=Srithawong|first1=Suparat|last2=Srikummool|first2=Metawee|last3=Pittayaporn|first3=Pittayawat|last4=Ghirotto|first4=Silvia|last5=Chantawannakul|first5=Panuwan|last6=Sun|first6=Jie|last7=Eisenberg|first7=Arthur|last8=Chakraborty|first8=Ranajit|last9=Kutanan|first9=Wibhu|date=July 2015|title=Genetic and linguistic correlation of the Kra-Dai-speaking groups in Thailand|url=https://www.ncbi.nlm.nih.gov/m/pubmed/25833471/|journal=Journal of Human Genetics|volume=60|issue=7|pages=371–380|doi=10.1038/jhg.2015.32|issn=1435-232X|pmid=25833471|s2cid=21509343|doi-access=free}}</ref>

Although the position of Kra-Dai in relation to Austronesian is still contested, some propose that Kra-Dai and Austronesian are genetically connected. Weera Ostapirat (2005) sets out a series of regular sound correspondences between them, assuming a model of a primary split between the two; they would then be co-ordinate branches.{{sfn|Blench|2017|p=11}} Weera Ostapirat (2013) continues to maintain that Kra-Dai and Austronesian are sister language families, based on certain phonological correspondences.{{sfn|Ostapirat|2013|pp=1–10}} On the other hand, Laurent Sagart (2008) proposes that Kra-Dai is a later form of ''FATK'',<ref group=lower-alpha name="FATK">Formosan ancestor of Tai-Kadai.</ref> a branch of Austronesian belonging to the subgroup ''Puluqic'' developed in Taiwan, whose speakers migrated back to the mainland, both to Guangdong, Hainan and north Vietnam around the second half of the 3rd millennium BCE.{{sfn|Sagart|2008|pp=146–152}} Upon their arrival in this region, they underwent linguistic contact with an unknown population, resulting in a partial relexification of FATK vocabulary.{{sfn|Sagart|2008|p=151}} If Sagart's hypothesis that Kra-Dai is a sub-group of Austronesian migrated out of Taiwan and back to the coastal regions of Guangdong, Guangxi, Hainan, and (possibly) Vietnam is right, they would simply not have had a development resembling anything like the fate of other Austronesian languages that migrated out of Taiwan to the Philippines and other islands in Southeast Asia.{{sfn|Brindley|2015|p=51}} Besides various concrete pieces of evidence for a Kra-Dai existence in the present-day Guangdong, remnants of Kra–Dai languages spoken further north can be found in unearthed [[Social:Chinese bronze inscriptions|inscriptional materials]] and non-Han substrata in [[Social:Min Chinese|Min]] and [[Social:Wu Chinese|Wu Chinese]].

Wolfgang Behr (2002, 2006, 2009, 2017){{sfn|Behr|2002}}{{sfn|Behr|2006}}{{sfn|Behr|2009}} points out that most of non-Sinitic words found in Chu [[Social:Chinese bronze inscriptions|inscriptional materials]] are of Kra-Dai origin. For example, the Chu graph for 'one, once' written as [[File:Neng2.svg|20px]] (? < [[Social:Old Chinese|OC]] '''*nnəŋ''') in the ''E jun qijie'' 鄂君啟筯 bronze tally and in Warring States bamboo inscriptions, which represents a Kra-–Dai areal word; compare Proto-Tai '''*hnïŋ''' ''='' '''*hnɯŋ''' (Siamese <sup>22</sup>nɯŋ, Dai <sup>33</sup>nɯŋ, Longzhou nəəŋ<sup>A</sup> etc.) 'one, once'.{{sfn|Behr|2017|p=12}}

In the early 1980s, Wei Qingwen (韦庆稳), a Zhuang linguist, proposed that the [[Social:Old Yue language|Old Yue language]] recorded in the Song of the Yue Boatman is in fact a language ancestral to Zhuang.{{sfn|Holm|2013|p=785}} Wei used reconstructed [[Social:Old Chinese|Old Chinese]] for the characters and discovered that the resulting vocabulary showed strong resemblance to modern Zhuang.{{sfn|Edmondson|2007|p= 16}} Later, Zhengzhang Shangfang (1991) followed Wei's proposal but used Thai script for comparison, since this orthography dates from the 13th century and preserves archaisms not found in modern pronunciation.{{sfn|Edmondson|2007|p= 16}}{{sfn|Zhengzhang|1991|pp= 159–168}} Zhengzhang notes that 'evening, night, dark' bears the C tone in Wuming Zhuang ''xam<sup>C2</sup>'' and ''ɣam<sup>C2</sup>'' 'night'. The item ''raa'' normally means 'we (inclusive)' but in some places, e.g. Tai Lue and White Tai 'I'.{{sfn|Edmondson|2007|p=17}} However, Laurent Sagart criticizes Zhengzhang's interpretation as anachronistic, because however archaic that Thai script is, the Thai language was only written 2000 years after the song had been recorded; even if Proto-Kam-Tai had emerged by the 6th century BCE, its pronunciation would have been substantially different from Thai.{{sfn|Sagart|2008|p=143}}

==Internal classification==
[[File:"tooth" in Kra-Dai languages.svg|thumb|300x300px|Example of the divergence among the Kra-Dai languages, using the word for "tooth".]]
Kra–Dai consists of at least five well established branches, namely Kra, Kam–Sui, Tai, Be and Hlai (Ostapirat 2005:109).

;Tai: Southern China and Southeast Asia
;Kra: Southern China, Northern Vietnam; called ''Kadai'' in ''[[Social:Ethnologue|Ethnologue]]'' and ''Geyang'' (仡央) in Chinese
;Kam–Sui: Guizhou and Guangxi, China
;Be: Hainan; possibly also includes [[Social:Jizhao language|Jizhao]] of Guangdong
;[[Social:Hlai languages|Hlai]]: Hainan

Chinese linguists have also proposed a Kam–Tai group that includes Kam–Sui, Tai and Be.<ref name="ReferenceA">Liang Min 梁敏 & Zhang Junru 张均如. 1996.

''Dongtai yu gailun'' 侗台语概论 / ''An introduction to the Kam-Tai languages''. Beijing: Central Nationalities Research Institute Press 中央民族学院出版社.</ref>

Kra–Dai languages that are not securely classified and may constitute independent Kra–Dai branches, include the following.
*'''[[Social:Lakkia language|Lakkia]]''' and '''[[Social:Biao language|Biao]]''', which may or may not subgroup with each other, are difficult to classify due to aberrant vocabulary, but are sometimes classified as [[Biology:Sister group|sisters]] of Kam–Sui (Solnit 1988).<ref name="Solnit1988"/>
*'''[[Social:Jiamao language|Jiamao]]''' of Southern Hainan, China is an aberrant Kra–Dai language traditionally classified as a [[Social:Hlai languages|Hlai language]], although Jiamao contains many words of non-Hlai origin.
*'''[[Social:Jizhao language|Jizhao]]''' of Guangdong, China is currently unclassified within Kra–Dai, but appears to be most closely related to Be (Ostapirat 1998).<ref name="Ostapirat1998">Ostapirat, W. (1998). [https://www.jstor.org/stable/23756759 A Mainland Bê Language? / 大陆的Bê语言？]. ''Journal of Chinese Linguistics'', 26(2), 338–344</ref>

Kra–Dai languages of mixed origins are:
*''Hezhang Buyi'': Northern Tai and Kra
*''[[Social:E language|E]]'': Northern Tai and [[Social:Pinghua|Pinghua]] Chinese
*''Caolan'': Northern Tai and Central Tai
*''[[Social:Sanqiao language|Sanqiao]]'': Kam–Sui, [[Social:Hmongic languages|Hmongic]] and Chinese
*''[[Social:Jiamao language|Jiamao]]'': [[Social:Hlai languages|Hlai]] and other unknown elements ([[Social:Austroasiatic languages|Austroasiatic]]?)

===Ostapirat (2005); Norquest (2007)===
Weera Ostapirat (2005:128) suggests the possibility of Kra and Kam–Sui being grouped together as Northern Kra–Dai and Hlai with Tai as Southern Kra–Dai.<ref name=Ostapirat2005/> Norquest (2007) has further updated this classification to include [[Social:Lakkia language|Lakkia]] and Be. Norquest notes that Lakkia shares some similarities with Kam–Sui, while Be shares some similarities with Tai. Norquest (2007:15) notes that Be shares various similarities with Northern Tai languages in particular.<ref name="norquest">Norquest, Peter K. 2007. [http://gradworks.umi.com/32/84/3284367.html ''A Phonological Reconstruction of Proto-Hlai''].

==Hypotheses regarding external relationships==
===Austro-Tai===
{{Main|Social:Austro-Tai languages}}
[[File:Genesis of Daic languages and their relation with Austronesians.png|thumb|Proposed genesis of Daic languages and their relation with [[Social:Austronesian languages|Austronesian languages]] (Blench, 2018)<ref name="Blench2018">{{cite book|url=https://www.academia.edu/37593287|title=Tai-Kadai and Austronesian are Related at Multiple Levels and their Archaeological Interpretation (draft)|last1=Blench|first1=Roger|year=2018|quote=The volume of cognates between Austronesian and Daic, notably in fundamental vocabulary, is such that they must be related. Borrowing can be excluded as an explanation}}</ref>]]
Several scholars have presented  evidence that Kra–Dai may be related to, or even be a branch of the [[Social:Austronesian languages|Austronesian language family]].<ref>{{cite journal|surname=Sagart|given=Laurent|year=2004|url=http://halshs.archives-ouvertes.fr/docs/00/09/09/06/PDF/THE_HIGHER_PHYLOGENY_OF_AUSTRONESIAN.pdf|title=The higher phylogeny of Austronesian and the position of Tai–Kadai|journal=Oceanic Linguistics|volume=43|issue=2|pages=411–440|doi=10.1353/ol.2005.0012|s2cid=49547647}}</ref> There are a number of possible cognates in the core vocabulary displaying regular sound correspondences. Among proponents, there is yet no agreement as to whether they are a sister group to Austronesian in a family called [[Social:Austro-Tai languages|Austro-Tai]], a back-migration from Taiwan to the mainland or a later migration from the Philippines to Hainan during the Austronesian expansion.{{sfn|Ostapirat|2013|pp = 1–10}}

The inclusion of [[Social:Japonic languages|Japanese]] in the Austro-Tai family, as proposed by Paul K. Benedict in the late 20th century,<ref>{{Cite book|title=Japanese/Austro-Tai|last=Benedict|first=Paul K.|date=1990|publisher=Karoma|isbn=978-0-89720-078-3}}</ref> is not supported by the current proponents of the Austro-Tai hypothesis.

===Sino-Tai===
The Kra–Dai languages were formerly considered to be part of the [[Social:Sino-Tibetan languages|Sino-Tibetan family]], partly because they contain large numbers of words that are similar to Sino-Tibetan languages. However, Western scholars generally consider them to be Sinitic loanwords and note that basic vocabulary words in Kra–Dai languages often have cognates with Austronesian instead.<ref name=Ostapirat2005>Ostapirat, Weera. (2005). "Kra–Dai and Austronesian: Notes on phonological correspondences and vocabulary distribution", pp.&nbsp;107–131 in Sagart, Laurent, Blench, Roger & Sanchez-Mazas, Alicia (eds.), ''The Peopling of East Asia: Putting Together Archaeology, Linguistics and Genetics.'' London/New York: Routledge-Curzon.</ref> Outside China, the Kra–Dai languages are now classified as an independent family. In China, they are called ''Dong–Tai'' (侗台) or ''Zhuang–Dong'' (壮侗) languages and are generally included, along with the [[Social:Hmong–Mien languages|Hmong–Mien languages]], in the Sino-Tibetan family.<ref>Luo, Yongxian. 2008. Sino-Tai and Tai-Kadai: Another look. In Anthony V. N. Diller and Jerold A. Edmondson and Yongxian Luo (eds.), ''The Tai-Kadai Languages'', 9–28. London & New York: Routledge.</ref>

===Hmong-Mien===
Kosaka (2002) argued specifically for a [[Social:Proto-Hmong–Mien#Kra-Dai|Miao–Dai family]]. Based on proposed lexical cognates, he argues for a genetic relation between [[Social:Hmong–Mien languages|Hmong–Mien]] and Kra–Dai languages. He further suggests that similarities between Kra–Dai and [[Social:Austronesian languages|Austronesian]] are due to later areal contact in the coastal areas of Eastern and Southeastern China or an older ancestral relation (Proto-[[Social:East Asian languages|East Asian]]).<ref name="Kosaka">Kosaka, Ryuichi. 2002.

===Japonic===
Vovin (2014) proposed that the location of the [[Social:Japonic languages|Japonic]] Urheimat (linguistic homeland) is in Southern China. Vovin argues for typological evidence that Proto-Japanese may have been a monosyllabic, SVO syntax and isolating language, which are also characteristic of Kra–Dai languages. According to him, these common features are however not due to a genetic relationship, but rather the result of intense contact.<ref name=Vovin>Vovin, Alexander (2014).
