Traditionally, the term "subject" in Chinese linguistics is defined as "what the sentence is about," a definition very close to that of "topic" in pragmatics. As the late Professor Yuen Ren Chao rightly pointed out, "the grammatical meaning of subject in a Chinese sentence is topic..." However, there is a recent practice to rename "subject" as such "topic" and establish another "subject" (called "[syntactic] subject" in this article) according mainly to its "selectional relationship with the verb in the sentence." The article disputes the viability of eatablishing the "(syntactic) subject" as it lacks linguistic features, and demonstrates that analysis of sentence structure in Chinese can be done properly by referring to the concept "topic" as Chinese is a topic prominant language.
