Chinese is a group of related but in many cases mutually unintelligible language varieties, forming a branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many other ethnic groups in China. Nearly 1.2 billion people (around 16% of the world’s population) speak some form of Chinese as their first language.
The varieties of Chinese are usually described by native speakers as dialects of a single Chinese language, but linguists note that they are as diverse as a language family. There are between 7 and 13 main regional groups of Chinese (depending on classification scheme), of which the most spoken by far is Mandarin (about 960 million), followed by Wu (80 million), Yue (60 million) and Min (70 million). Most of these groups are mutually unintelligible, although some, like Xiang and the Southwest Mandarin dialects, may share common terms and some degree of intelligibility. All varieties of Chinese are tonal and analytic.
