The Dai people (Burmese: ရှမ်းလူမျိုး; ᨴᩱ/ᨴᩱ᩠ᨿ; ໄຕ; ไท; တႆး, [tai˥˩]; ᥖᥭᥰ, [tai˥]; ) are several Tai-speaking ethnic groups living in the Xishuangbanna Dai Autonomous Prefecture and the Dehong Dai and Jingpo Autonomous Prefecture of China's Yunnan Province. The Dai people form one of the 56 ethnic groups officially recognized by the People's Republic of China. By extension, the term can apply to groups in Laos, Vietnam, Thailand and Myanmar when Dai is used to mean specifically Tai Yai, Lue, Chinese Shan, Tai Dam, Tai Khao or even Tai in general. For other names, please see the table below. The Dai people are closely related to the Lao and Thai people who form a majority in Laos and Thailand. Originally, the Tai, or Dai, lived closely together in modern Yunnan Province until political chaos and wars in the north at the end of the Tang and Song dynasty and various nomadic peoples prompted some to move further south into modern Laos then Thailand. As with many other officially recognized ethnic groups in China (See Gaoshan and Yao), the term Dai, at least within Chinese usage, is an umbrella term and as such has no equivalent in Tai languages, who have only more general terms for 'Tai peoples in general' (e.g., Tai Lue: tai˥˩. This term refers to all Dai people, not including Zhuang) and 'Tai people in China' (e.g., ชาวไทในจีน'), both of which include the Zhuang, for example, which is not the case in the Chinese and more specific terms, as shown in the table below. Therefore the word Dai, like with the aforementioned Yao, is a Han Chinese cultural concept which has now been adopted by other languages such as English, French, and German (see respective Wikipedias). As a solution in the Thai language, however, as in English, the term Tai Lue can be used to mean Dai, despite referring to other groups as in the table below. This is because the two main groups actually bear the same name, both meaning 'Northern Tai' (lue and nüa are cognate). Although they are officially recognized as a single people by the Chinese state, these Tai people form several distinct cultural and linguistic groups.
