非范畴化与回文结构逆向对称重叠

回文语言的独特性，绝妙的文字驾驭，是其它修辞所无法比拟的。从认知语言学角度分析回文的语义范畴，认为回文语义存在一定非范畴化特征，即在语义上表现为范畴成员逆向对称重叠的并列组合关系；句法上，范畴成员位置移动，突破了组合关系或聚合关系的常规限制，使得回文的后部分语义发生非范畴化变异；语境上，在认知参照点的作用下，回文的前后部分语义关系可能相似而形成统一关系，也可能相反而产生对立关系。这种关系使得回文语义发生非范畴化变异，在语用功能上违背了常规语言关系的限制，从而实现回文前景化语言的震撼性修辞表达效果。

Decategorization and Symmetrical Overlap of Structure Reversal in Palindrome

A palindrome is a kind of excellent rhetorics with its peculiar characteristic that is incomparable to others.This paper analyzes semantic categorization of palindrome from the perspective of cognitive linguistic theory and holds that there are certain degrees of semantic decategorization in palindrome as follows:semantically,its same members in the palindrome category can form syntagmatic relation in the juxtaposition by symmetrical overlap of structure reversal;syntactically,position movement of the same members in the palindrome category may break through regular restrictions of either syntagmatic or paradigmatic relation that make decategorization in the back part of the palindrome;contextually,the fore and back part of the palindrome are relevant by similarity in union or opposition in reverse under roles of the reference point.Pragmatically, semantic deviation causes decategorization in the back part of the palindrome violating the above common linguistic restrictions for the overwhelming of foregrounding linguistic rhetoric effects of the palindrome.
