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.The internal diversity of Chinese has been likened to that of the Romance languages. 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 (50 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.
