Chinese (/ ''Hànyǔ''), also known as Sinitic, is a branch of the Sino-Tibetan language family consisting of hundreds of local language varieties, many of which are not mutually intelligible. The differences are similar to those within the Romance languages, with variation particularly strong in the more rugged southeast. These varieties have been classified into seven to ten groups, the largest being Mandarin (e.g. Beijing dialect), Wu (e.g. Shanghainese), Min (e.g. Taiwanese Hokkien), and Yue (e.g. Cantonese). Chinese varieties differ most in their phonology, and to a lesser extent in vocabulary and syntax. Southern varieties tend to have fewer initial consonants than northern and central varieties, but more often preserve the Middle Chinese final consonants. All have phonemic tones, with northern varieties tending to have fewer distinctions than southern ones. Many have tone sandhi, with the most complex patterns in the coastal area from Zhejiang to eastern Guangdong. == History == At the end of the 2nd millennium BC, a form of Chinese was spoken in a compact area around the lower Wei River and middle Yellow River. From there it expanded eastwards across the North China Plain to Shandong and then south into the valley of the Yangtze River and beyond to the hills of south China. As the language spread, it replaced formerly dominant languages in those areas, and regional differences grew. Simultaneously, especially in periods of political unity, there was a tendency to promote a central standard to facilitate communication between people from different regions. The first evidence of dialectal variation is found in texts from the Spring and Autumn period (722–479 BC). At that time, the Zhou royal domain, though no longer politically powerful, still defined standard speech. The ''Fangyan'' (early 1st century AD) is devoted to differences in vocabulary between regions. Commentaries from the Eastern Han period (first two centuries AD) contain much discussion of local variations in pronunciation. The ''Qieyun'' rhyme book (601 AD) noted wide variation in pronunciation between regions, and set out to define a standard pronunciation for reading the classics. This standard, known as Middle Chinese, is believed to be a diasystem based on the reading traditions of northern and southern capitals. The North China Plain provided few barriers to migration, leading to relative linguistic homogeneity over a wide area in northern China. In contrast, the mountains and rivers of southern China have spawned the other six major groups of Chinese languages, with great internal diversity, particularly in Fujian. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Varieties of Chinese」の詳細全文を読む スポンサード リンク
