本文从历时的角度，对“否定词+说”类话语标记的形成及演变做出分析，重点围绕“别说”、“休说”“莫说”、“不说”几个词的历时发展，探求它们如何由“副词+动词”词组衍生出话语标记的用法，在语篇中发挥作用。“别说”、“休说”“莫说”、“不说”几个词在语义上存在共同点，即都含有[+否定义]义素，但是它们演变出话语标记的路径却不尽相同，对他们演变的路径进行历时考察，具有一定的研究价值。

From a diachronic perspective, this paper analyzes the formation and evolution of the "negative word + say" type of discourse markers, focusing on the diachronic development of "bie shuo", "xiu shuo", "mo shuo" and "bu shuo", and explores how they derive the usage of discourse markers from the phrase "adverb + verb" and play a role in the discourse. "bie shuo", "xiu shuo", "mo shuo" and "bu shuo" have some semantically common ground, that is, they all contain [+ negative] sememe, but they have different paths to develop discourse markers, and it is of certain research value to make a diachronic investigation of their evolution paths.
