文体学是一个外延宽泛、内涵丰富的学科概念[1]。一方面它是文学创作的基本前提和理论原则,另一方面它也是文学理论与批评的核心与基点,在文学作品的研究、分析中起着关键作用。本文以中国古代文体学为主,辅之以西方文体学相关内容,试图从体裁、语体、功能三个方面入手,对“文体学”做较为清晰的阐释。 Stylistics is a broad extension of the connotation of the subject concept [1]. On the one hand, it is the basic prerequisite and theoretical principle of literary creation. On the other hand, it is also the core and starting point of literary theory and criticism. It plays a key role in the research and analysis of literary works. Based on the ancient Chinese stylistics and supplemented by Western stylistics, this article attempts to make a clearer explanation of “stylistics” from three aspects: genre, style and function.
