Classical Chinese grammar

Classical Chinese grammar is the grammar of Classical Chinese, a term that first and foremost refers to the written language of the classical period of Chinese literature, from the end of the Spring and Autumn period (early 5th century BC) to the end of the Han Dynasty (220 AD). The term "Classical Chinese" is also often used for the higher language register used in writing during most of the following centuries (a register generally referred to by sinologists as "Literary Chinese"); however, this article focuses on the grammar used in the classical period.

The present article uses modern Mandarin character readings following common practice among scholars, even though it is also possible to read Classical Chinese using the literary readings of other modern Chinese varieties (as commonly done in Hong Kong, where Cantonese readings are generally used), or even using a reconstruction of character readings belonging to centuries past.

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.

Classical Chinese has been long noted for the absence of inflectional morphology: nouns and adjectives do not inflect for case, definiteness, gender, Specificity or number; neither do verbs inflect for person, number, tense, aspect, telicity, valency, evidentiality or voice. However, in terms of derivational morphology, it makes use of compounding, reduplication and perhaps affixation, although not in a productive way. There is also an extensive use of zero-derivation.
