SIL's dedication to language development past and present
Wenshan Zhuang and Miao Autonomous Prefecture in China’s Yunnan province is home to over a million members of the official Zhuang nationality. Over half of these speak language varieties classified into the central branch of Tai languages. Though many of the languages of the southwestern branch of Tai (which includes Thai and Lao) have been extensively studied by Thai and other linguists, and the northern branch (which includes the government designated standard varieties for both the Zhuang and Bouyei nationalities) are the subject of numerous works by Chinese linguists, relatively few works focused on Central Tai languages are available. The aim of this work is to provide sociolinguistic data from the several Central Taic Zhuang languages of Wenshan prefecture, resulting from sociolinguistic field research conducted from 2005 to 2007.
