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.
Classical Chinese grammar
Compared to the written vernacular Chinese of today, the most notable difference is that Classical Chinese rarely uses words composed of two Chinese characters; nearly all words are written with one character only. This stands directly in contrast with vernacular Chinese, in which two-character words are extremely common. This phenomenon exists, in part, because as sound changes created homophones among words, compounding was used to resolve ambiguities.
