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.

Until the early 20th century, formal writing and even much poetry and fiction was done in Literary Chinese, which was modeled on the classics of the Warring States period and the Han dynasty. Over time, the various spoken varieties diverged greatly from Literary Chinese, which was learned and composed as a special language. Preserved from the sound changes that affected the various spoken varieties, its economy of expression was greatly valued. For example, ("yì," "wing") is unambiguous in written Chinese, but has over 75 homophones in Standard Chinese.
