Lower Yangtze Mandarin in the context of "Anhui"

Chinese (spoken: simplified Chinese: 汉语; traditional Chinese: 漢語; pinyin: Hànyǔ, written: 中文; Zhōngwén) is an umbrella term for Sinitic languages in the Sino-Tibetan language family, widely recognized as a group of language varieties, spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in China, as well as by various communities of the Chinese diaspora. Approximately 1.39 billion people, or 17% of the global population, speak one of the Chinese languages as their first language.

The Chinese languages form the Sinitic branch of the Sino-Tibetan language family. The Chinese government considers the spoken varieties of the Chinese languages dialects of a single language. However, their lack of mutual intelligibility means they are considered to be separate languages in a family by linguists. Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese, of which the most spoken by far is Mandarin with 66%, or around 800 million speakers, followed by Min (75 million, e.g., Southern Min), Wu (74 million, e.g., Shanghainese), and Yue (68 million, e.g., Cantonese). These branches are unintelligible to each other, and many of their subgroups are unintelligible with the other varieties within the same branch (e.g., Southern Min). There are, however, transitional areas where varieties from different branches share enough features for some limited intelligibility, including New Xiang with Southwestern Mandarin, Xuanzhou Wu Chinese with Lower Yangtze Mandarin, Jin with Central Plains Mandarin and certain divergent dialects of Hakka with Gan. All varieties of Chinese are tonal at least to some degree, and are largely analytic.

Mandarin (/ˈmændərɪn/ MAN-dər-in; simplified Chinese: 官话; traditional Chinese: 官話; pinyin: Guānhuà; lit. 'officials' speech') is the largest branch of the Sinitic languages. Mandarin varieties are spoken by 70 percent of all Chinese speakers over a large geographical area that stretches from Yunnan in the southwest to Xinjiang in the northwest and Heilongjiang in the northeast. Its spread is generally attributed to the greater ease of travel and communication in the North China Plain compared to the more mountainous south, combined with the relatively recent spread of Mandarin to frontier areas.

Many varieties of Mandarin, such as those of the Southwest (including Sichuanese) and the Lower Yangtze, are not mutually intelligible with the Beijing dialect (or are only partially intelligible). Nevertheless, Mandarin as a group is often placed first in lists of languages by number of native speakers (with nearly one billion). Because Mandarin originated in North China and most Mandarin varieties are found in the north, the group is sometimes referred to as Northern Chinese (simplified Chinese: 北方话; traditional Chinese: 北方話; pinyin: Běifānghuà; lit. 'northern speech').
