The Zhuang languages (; autonym: , Sawndip: ) are more than a dozen Tai languages spoken by the Zhuang people of Southern China in the province of Guangxi and adjacent parts of Yunnan and Guangdong. The Zhuang languages do not form a monophyletic linguistic unit, as northern and southern Zhuang languages are more closely related to other Tai languages than to each other. Northern Zhuang languages form a dialect continuum with Northern Tai varieties across the provincial border in Guizhou, which are designated as Bouyei, whereas Southern Zhuang languages form another dialect continuum with Central Tai varieties such as Nung, Tay and Caolan in Vietnam. Standard Zhuang is based on the Northern Zhuang dialect of Wuming.
The Tai languages are believed to have been originally spoken in what is now southern China, with speakers of the Southwestern Tai languages, which include Thai (modern-day Thailand), Lao (modern-day Laos) and Shan (modern-day Shan State, Myanmar) having emigrated south in the face of Chinese expansion. Noting that both the Zhuang and Thai peoples have the same exonym for the Vietnamese, kÃÂÃÂu<sup>A1</sup>, from the Chinese commandery of Jiaozhi in northern Vietnam, Jerold A. Edmondson posited that the split between Zhuang and the Southwestern Tai languages happened no earlier than the founding of Jiaozhi in 112 BC. He also argues that the departure of the Thai from southern China must predate the 5th century AD, when the Tai who remained in China began to take family names.
ZhÃÂng Jà «nrú's (å¼µåÂÂå¦Â) ZhuàngyàFÃÂngyán Yánjiù (壯èªÂæÂ¹è¨Âç Âç©¶ [A Study of Zhuang dialects]) is the most detailed study of Zhuang dialectology published to date. It reports survey work carried out in the 1950s, and includes a 1465-word list covering 36 varieties of Zhuang. For the list of the 36 Zhuang variants below from Zhang (1999), the name of the region (usually county) is given first, followed by the specific village. The phylogenetic position of each variant follows that of Pittayaporn (2009) (see Tai languages#Pittayaporn (2009)).
The Zhuang language (or language group) has been divided by Chinese linguists into northern and southern "dialects" (fÃÂngyán æÂ¹è¨ in Chinese), each of which has been divided into a number of vernacular varieties (known as tÃÂyàåÂÂ誠in Chinese) by Chinese linguists (Zhang & Wei 1997; Zhang 1999:29-30). The Wuming dialect of Yongbei Zhuang, classified within the "Northern Zhuang dialect", is considered to be the "standard" or prestige dialect of Zhuang, developed by the government for certain official usages. Although Southern Zhuang varieties have aspirated stops, Northern Zhuang varieties lack them. There are over 60 distinct tonal systems with 5âÂÂ11 tones depending on the variety.
Zhang (1999) identified 13 Zhuang varieties. Later research by the Summer Institute of Linguistics has indicated that some of these are themselves multiple languages that are not mutually intelligible without previous exposure on the part of speakers, resulting in 16 separate ISO 639-3 codes.
Northern Zhuang comprises dialects north of the Yong River, with 8,572,200 speakers ( [] prior to 2007):
In east-central Guangxi, there are isolated pockets of Northern Zhuang speakers in Zhongshan (14,200 Zhuang people), Pingle (2,100 Zhuang people), Zhaoping (4,300 Zhuang people), Mengshan (about 5,000 Zhuang people), and Hezhou (about 3,000 Zhuang people) counties. These include the following varieties named after administrative villages that are documented by Wei (2017).
Southern Zhuang dialects are spoken south of the Yong River, with 4,232,000 speakers ( [] prior to 2007):
The Tày and Nùng language complex in Vietnam is also considered one of the varieties of Central Tai and shares a high mutual intelligibility with Wenshan Dai and other Southern Zhuang dialects in Guangxi. The Nùng An language has a mixture of Northern and Central Tai features.
Johnson (2011) distinguishes four distinct Zhuang languages in Wenshan Prefecture, Yunnan: Nong Zhuang, Yei Zhuang, Dai Zhuang, and Min Zhuang, all of which are Southern Zhuang varieties except for Yei Zhuang, which is Northern Zhuang. Min Zhuang is a recently discovered Southern Zhuang variety that has never been described previous to Johnson (2011). (See also Wenshan Zhuang and Miao Autonomous Prefecture#Ethnic groups)
Pyang Zhuang and Myang Zhuang are recently described Southern Zhuang (Central Tai) languages spoken in Debao County, Guangxi, China.
The Zhuang languages have been written in the ancient sawndip script for over a thousand years, possibly preceded by the sawgoek script. Sawndip is based on Chinese characters, similar to Vietnamese chữ Nôm. Some sawndip logograms were directly borrowed from Han characters, whereas others were created locally from components of Chinese characters. It has been used for writing songs, and more recently in public communications encouraging people to follow official family planning policy.
There has also been the occasional use of a number of other scripts, including pictographic proto-writing.
In 1957, a hybrid script based on the Latin script and expanded with Cyrillic- and IPA-derived letters was introduced to write Standard Zhuang. In 1982, it was updated to use only Latin letters. These are referred to as the "old" and "new" Zhuang, respectively. Bouyei is written in Latin script.
