Languages

Ethnologue distinguishes the following languages.

• Saek (Laos and northeast Thailand; listed outside Tai proper in the Ethnologue classification, though said to be similar to Tai Maen, which is listed as Northern Tai)
• Tai Maen (Laos)
• Yoy (Thailand) [?]
• Bouyei (Buyi) (China) (including the language of the Giáy people of Vietnam)
• Central Hongshuihe Zhuang
• Eastern Hongshuihe Zhuang
• Guibei Zhuang
• Yei Zhuang
• Lianshan Zhuang
• Liujiang Zhuang
• Liuqian Zhuang
• Yongbei Zhuang
• Youjiang Zhuang

(See varieties of Zhuang.)

Yoy is elsewhere classified as Southwestern Tai, and E, which appears to be a mixed language on a Northern Thai base.

Pittayaporn (2009:300) distinguishes a similar group of Zhuang varieties as group "N", defined by the phonological shifts *ɯj, *ɯw → *aj, *aw. He moves the prestige dialect of Zhuang, the Wuming dialect, from the Northern Tai Yongbei Zhuang to Yongnan Zhuang - purportedly Central Tai - as it lacks these shifts. The various languages and localities Pittayaporn includes in group N, along with their Ethnologue equivalents, are:
