Language family of mainland Southeast Asia From Wikipedia, the free encyclopedia
The Kra–Dai languages (/ˈkrɑː.daɪ/ KRAH-dy, also known as Tai–Kadai /ˈtaɪ.kəˌdaɪ/ TIE-kə-DYE and Daic /ˈdaɪ.ɪk/ DYE-ik), are a language family in mainland Southeast Asia, southern China, and northeastern India. All languages in the family are tonal, including Thai and Lao, the national languages of Thailand and Laos, respectively.[1] Around 93 million people speak Kra–Dai languages; 60% of those speak Thai.[2] Ethnologue lists 95 languages in the family, with 62 of these being in the Tai branch.[3]

Distribution of the Tai–Kadai language family. | |
The name "Kra–Dai" was proposed by Weera Ostapirat (2000), as Kra and Dai are the reconstructed autonyms of the Kra and Tai branches, respectively.[4] "Kra–Dai" has since been used by the majority of specialists working on Southeast Asian linguistics, including Norquest (2007),[5] Pittayaporn (2009),[6][7] Baxter & Sagart (2014),[8] and Enfield & Comrie (2015).[9]
The name "Tai–Kadai" is used in many references, as well as Ethnologue and Glottolog, but Ostapirat (2000) and others suggest that it is problematic and confusing, preferring the name "Kra–Dai" instead.[4] "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).[10] In 1942, Benedict placed three Kra languages (Gelao, Laqua (Qabiao), and Lachi) together with Hlai in a group that he called "Kadai", from ka, meaning "person" in Gelao and Laqua and dai, a form of a Hlai autonym.[10] Benedict's (1942) "Kadai" group was based on his observation that Kra and Hlai languages have 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).[11][12] Adding to the confusion, some other references[which?] restrict the usage of "Kadai" to only the Kra branch of the family.
The name "Daic" is used by Roger Blench (2008).[13]
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.[15] The high diversity of Kra–Dai languages in southern China, especially in Guizhou and Hainan, points to that being an origin of the Kra–Dai language family, founding the nations that later became Thailand and Laos in what had been Austroasiatic territory. Genetic and linguistic analyses show great homogeneity among Kra–Dai-speaking people in Thailand.[16]
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.[17] Ostapirat (2013) continues to maintain that Kra–Dai and Austronesian are sister language families, based on certain phonological correspondences.[18] On the other hand, Laurent Sagart (2008) proposes that Kra–Dai is a later form of what he calls "FATK" (Formosan Ancestor of Tai–Kadai) a branch of Austronesian belonging to the subgroup "Puluqic", developed in Taiwan, whose speakers migrated back to the mainland, to Guangdong, Hainan, and north Vietnam, around the second half of the 3rd millennium BCE.[19] Upon their arrival in this region, they underwent linguistic contact with an unknown population, resulting in a partial relexification of FATK[lower-alpha 1] vocabulary.[20] Erica Brindley (2015) supports Sagart's hypothesis, arguing that the radically different Kra-Dai history of migration to the mainland (as opposed to the Philippines for Proto-Austronesian) and extended contact with Austro-Asiatic and Sinitic speakers would make the relationship appear more distant. She also suggests that the presence of only the most basic Austronesian vocabulary in Kra-Dai makes this scenario of relexification more plausible.[21]
Besides various concrete pieces of evidence for a Kra–Dai existence in present-day Guangdong, remnants of Kra–Dai languages spoken further north can be found in unearthed inscriptional materials and non-Han substrata in Min and Wu Chinese.[citation needed]
Wolfgang Behr (2002, 2006, 2009, 2017)[22][23][24] points out that most non-Sinitic words found in Chu inscriptional materials are of Kra–Dai origin. For example, the Chu graph for 'one, once' written as 
(? < 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 22nɯŋ, Dai 33nɯŋ, Longzhou nəəŋA etc.) 'one, once'.[25]
In the early 1980s, Wei Qingwen (韦庆稳), a Zhuang linguist, proposed that the Old Yue language recorded in the Song of the Yue Boatman is in fact a language ancestral to Zhuang.[26] Wei used reconstructed Old Chinese for the characters and discovered that the resulting vocabulary showed strong resemblance to modern Zhuang.[27] 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.[27][28] Zhengzhang notes that 'evening, night, dark' bears the C tone in Wuming Zhuang xamC2 and ɣamC2 'night'. The item raa normally means 'we (inclusive)' but in some places, e.g., Tai Lue and White Tai, it means 'I'.[29] However, Laurent Sagart criticizes Zhengzhang's interpretation as anachronistic, because however archaic the Thai script is, the Thai language was only written 2,000 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.[30]

Kra–Dai consists of at least five well-established branches, namely Kra, Kam–Sui, Tai, Be, and Hlai (Ostapirat 2005:109).
Chinese linguists have also proposed a Kam–Tai group that includes Kam–Sui, Tai, and Be.[31][32]
Kra–Dai languages that are not securely classified and may constitute independent Kra–Dai branches include the following:
Kra–Dai languages of mixed origins are:
An early but influential classification, with the traditional Kam–Tai clade, was Edmondson and Solnit's classification from 1988:[12][34]
This classification is also used by Liang and Zhang (1996),[35] Chamberlain (2016: 38),[36] and Ethnologue, though by 2009 Lakkia was made a third branch of Kam–Tai and Biao was moved into Kam–Sui.
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.[37] Norquest (2007) has further updated this classification to include 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.[5] Following Ostapirat, Norquest adopts the name Kra–Dai for the family as a whole. The following tree of Kra–Dai is from Norquest (2007:16):
Additionally, Norquest (2007) also proposes a reconstruction for Proto-Southern Kra–Dai.
A classification of Kra–Dai by Norquest (2015, 2020) is provided as follows:[38][39]
Based on shared lexical innovations, Norquest (2021) significantly revised his classification of Kra–Dai. Together, Biao and Lakkja form the most divergent subgroup of Kra–Dai. Be–Tai and Hlai are placed together as part of a "Hlai–Tai" group.[40]
Several scholars have presented evidence that Kra–Dai may be related to, or even a branch of, the Austronesian language family.[42] 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 Austro-Tai, a back-migration from Taiwan to the mainland or a later migration from the Philippines to Hainan during the Austronesian expansion.[18]
The inclusion of Japanese in the Austro-Tai family, as proposed by Paul K. Benedict in the late 20th century,[43] is not supported by the current proponents of the Austro-Tai hypothesis.
The Kra–Dai languages were formerly considered to be part of the 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.[37] 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 Hmong–Mien languages, in the Sino-Tibetan family.[44]
Kosaka (2002) has argued specifically for a Miao–Dai family. Based on proposed lexical cognates, he proposes a genetic relation between Hmong–Mien and Kra–Dai languages. He further suggests that similarities between Kra–Dai and Austronesian are due to later areal contact in the coastal areas of eastern and southeastern China or an older ancestral relation (Proto-East Asian).[45]
Vovin (2014) has proposed that the location of the Japonic Urheimat (linguistic homeland) is in southern China. He argues for typological evidence that Proto-Japanese may have been a monosyllabic, SVO syntax and isolating language, which is 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.[46]
