Yongnan languages

Yongnan, or Yongnan Zhuang, is a putative Tai language of southern China.

In the classification of Pittiyaporn (2009), Yongnan is not a single language, or even a natural group, but parts of two main branches of the Tai language family (clades C, I, and M). See Tai languages#Pittayaporn (2009) for a list.
