The Old Yue language (Chinese: 古越語; pinyin: Gu Yueyu) is an unknown unclassified language (or many different languages). It can refer to Yue, which was spoken in the realm of Yue during the Spring and Autumn period. It can also refer to the variety of different languages spoken by the Baiyue. Possible languages spoken by them may have been of Kra–Dai, Hmong–Mien, Austronesian, Austroasiatic and other origins.

Knowledge of Yue speech is limited to fragmentary references and possible loanwords in other languages, principally Chinese. The longest attestation is the Song of the Yue Boatman, a short song transcribed phonetically in Chinese characters in 528 BC and included, with a Chinese version, in the Garden of Stories compiled by Liu Xiang five centuries later.^[1]

Native Nanyue people likely spoke Old Yue, while Han settlers and government officials spoke Old Chinese. Some suggest that the descendants of the Nanyue spoke Austroasiatic languages.^[2] Others suggest a language related to the modern Zhuang people. It is plausible to say that the Yue spoke more than one language. Old Chinese in the region was likely much influenced by Yue speech (and vice versa), and many Old Yue loanwords in Chinese have been identified by modern scholars.^[3]

Classification theories[]

There is some disagreement about the languages the Yue spoke, with candidates drawn from the non-Sinitic language families still represented in areas of southern China, pre-Kra–Dai, pre-Hmong–Mien, pre-Austronesian, and pre-Austroasiatic;^[4] as Chinese, Kra–Dai, Hmong–Mien, Austronesian, and the Vietic branch of Austroasiatic have similar tone systems, syllable structure, grammatical features and lack of inflection, but these features are believed to have spread by means of diffusion across the Mainland Southeast Asia linguistic area, rather than indicating common descent.^[5][6]

• Scholars in China often assume that the Yue spoke an early form of Kra–Dai. According to Sagart (2008), this is far from self-evident, because the core of the Kra–Dai area geographically is located in Hainan and the China-Vietnam border region, which is beyond the extreme southern end of the Yue area. The linguist Wei Qingwen gave a rendering of the "Song of the Yue boatman" in Standard Zhuang. Zhengzhang Shangfang proposed an interpretation of the song in written Thai (dating from the late 13th century) as the closest available approximation to the original language, but his interpretation remains controversial.^[1][7]
• Peiros (2011) shows with his analysis that the homeland of Austroasiatic is somewhere near the Yangtze. He suggests the Sichuan Basin as the likely homeland of proto-Austroasiatic speakers before they migrated to other parts of 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.^[8] The linguists Sagart (2011) and Bellwood (2013) support the theory of an origin of Austroasiatic along the Yangtze river in southern China.^{[9][better source needed]}
• Sagart (2008) suggests that the Old Yue language, together with the proto-Austronesian language, was descended from the language or languages of the Tánshíshān‑Xītóu culture complex (modern day Fujian province of China), making the Old Yue language a sister language to proto-Austronesian, which Sagart sees as the origin of the Kra–Dai languages.^[10]

Behr (2009) also notes that the Chǔ dialect of Old Chinese was influenced by several substrata, predominantly Kra-Dai, but also possibly Austroasiatic, Austronesian and Hmong-Mien.^[11]

Kra–Dai arguments[]

The proto-Kra–Dai language has been hypothesized to originate in the Lower Yangtze valleys. Ancient Chinese texts refer to non-Sinitic languages spoken across this substantial region and their speakers as "Yue". Although those languages are extinct, traces of their existence could be found in unearthed inscriptional materials, ancient Chinese historical texts and non-Han substrata in various Southern Chinese dialects. Thai, one of the Tai languages and the most-spoken language in the Kra–Dai language family, has been used extensively in historical-comparative linguistics to identify the origins of language(s) spoken in the ancient region of South China. One of the very few direct records of non-Sinitic speech in pre-Qin and Han times having been preserved so far is the "Song of the Yue Boatman" (Yueren Ge 越人歌), which was transcribed phonetically in Chinese characters in 528 BC, and found in the 善说 Shanshuo chapter of the Shuoyuan 说苑 or 'Garden of Persuasions'.

Willeam Meacham (1996) reports that Chinese linguists have shown strong evidence of Tai vestiges in former Yue areas: Lin (1990) found Tai elements in some Min dialects, Zhenzhang (1990) has proposed Tai etymologies and interpretations for certain place names in the former states of Wu and Yue, and Wei (1982) found similarities in the words, combinations and rhyming scheme betweenn the "Song of the Yue Boatman" and the Kam–Tai languages.^[12]

James R. Chamberlain (2016) proposes that the 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 state and the beginning of the Zhou dynasty.^[13] Following the southward migrations of Kra and Hlai (Rei/Li) peoples around the 8th century BCE, the Yue (Be-Tai people) started to break away and move to the east coast in the present-day Zhejiang province, in the 6th century BCE, forming the state of Yue and conquering the state of Wu shortly thereafter.^[13] According to Chamberlain, Yue people (Be-Tai) began to migrate southwards along the east coast of China to what are now Guangxi, Guizhou and northern Vietnam, after Yue was conquered by Chu around 333 BCE. There the Yue (Be-Tai) formed the polities Xi Ou, which became the Northern Tai and the Luo Yue, which became the Central-Southwestern Tai.^[13] However, Pittayaporn (2014), after examining layers of Chinese loanwords in proto-Southwestern Tai and other historical evidence, proposes that the southwestward migration of southwestern Tai-speaking tribes from the modern Guangxi to the mainland of Southeast Asia must have taken place only sometime between the 8th–10th centuries CE,^[14] long after 44 CE, when Chinese sources last mentioned Luo Yue in the Red River Delta.^[15]

Ancient textual evidence[]

In the early 1980s, Zhuang linguist, Wei Qingwen (韦庆稳), electrified the scholarly community in Guangxi by identifying the language in the "Song of the Yue Boatman" as a language ancestral to Zhuang.^[19] Wei used reconstructed Old Chinese for the characters and discovered that the resulting vocabulary showed strong resemblance to modern Zhuang.^[20] Later, Zhengzhang Shangfang (1991) followed Wei’s insight but used Thai script for comparison, since this orthography dates from the 13th century and preserves archaisms viz-à-viz the modern pronunciation.^[20][1] Zhengzhang notes that 'evening, night, dark' bears the C tone in Wuming Zhuang xam^C2 and ɣam^C2 'night'. The item raa normally means 'we inclusive' but in some places, e.g. Tai Lue and White Tai 'I'.^[21] However, Laurent criticizes Zhengzhang's interpretation as anachronistic, because however archaic that Thai script is, Thai language was only written 2000 years after the song had been recorded; even if the Proto-Kam-Tai might have emerged by 6th century BCE, its pronunciation would have been substantially different from Thai.^[7] The following is a simplified interpretation of the "Song of the Yue Boatman" by Zhengzhang Shangfang quoted by David Holm (2013) with Thai script and Chinese glosses being omitted:^[22][a]
