Written Chinese
Written Chinese () comprises Chinese characters used to represent the Chinese language. Chinese characters do not constitute an alphabet or a compact syllabary. Rather, the writing system is roughly logosyllabic; that is, a character generally represents one syllable of spoken Chinese and may be a word on its own or a part of a polysyllabic word. The characters themselves are often composed of parts that may represent physical objects, abstract notions, or pronunciation. Literacy requires the memorization of a great many characters: educated Chinese know about 4,000. The large number of Chinese characters has in part led to the adoption of Western alphabets as an auxiliary means of representing Chinese.
Chinese characters
Modern Chinese has many homophones; thus the same spoken syllable may be represented by many characters, depending on meaning. A single character may also have a range of meanings, or sometimes quite distinct meanings; occasionally these correspond to different pronunciations. Cognates in the several varieties of Chinese are generally written with the same character. They typically have similar meanings, but often quite different pronunciations. In other languages, most significantly today in Japanese and sometimes in Korean, characters are used to represent Chinese loanwords, to represent native words independently of the Chinese pronunciation (e.g., kunyomi in Japanese), and as purely phonetic elements based on their pronunciation in the historical variety of Chinese from which they were acquired. These foreign adaptations of Chinese pronunciation are known as Sino-Xenic pronunciations and have been useful in the reconstruction of Middle Chinese.
