Abstract:
Definite and "Indefinite" are a pair of categories of grammar, semantics and pragmatics that are common in different languages. Different from English, "Definite" and "Indefinite" in Chinese are a pair of implicit categories lacking of syntactic coercion, and are subject to pragmatic rules first. They can be regarded as a pragmatic means for speakers to achieve information packaging. This rule has been further verified by the study of the referential features of the object of "Ba" sentences.
