关于韩国语的助词“??”是否是“?”的异形态这一问题的探讨,语言学界历来争议不断。多数人认为两者是异形态关系,也有人认为两者不能构成真正意义上的异形态关系。本文首先考察了先行研究中对于异形态的定义、分类以及判定条件,在此基础上,本文认为,异形态关系的成立须符合两个条件,一是意义、功能相同,二是分布上具有互补性,两者缺一不可。接下来,通过考察“?”的用法发现,当表示“动作涉及的某个对象”意思时,“?”和“??”都可以使用,但是两者的语用意义不完全相同,而且语法功能是否相同也存在争议,再次,在互补性分布方面也存在很多例外。因此,严格上来说,“?”和“??”不符合异形态关系成立的两大条件,本文认为韩国语的助词“??”很难看成是“?”的异形态,将它们视为不同的形态素反而更具妥当性。 With regard to the discussion of the morpheme morphology of the Korean word “??” as “?”, Linguistics has always been controversial. Most people think that the two are heteromorphic, others think that the two can not form a true heteromorphic relationship. This paper first examines the definition, classification and judging conditions of heteromorphism in the pioneer study. Based on this, we conclude that the establishment of the heteromorphism relationship must meet two conditions: one is the meaning, the same is the function, and the other is the distribution is complementary Sex, both are indispensable. Next, by examining the usage of “?”, It is found that both “” and “” can be used when referring to the meaning of “object involved in an action.” However, The meaning is not exactly the same, and the grammatical function is also controversial, and again, there are many exceptions to the complementary distribution. Therefore, strictly speaking, “? ” And “?? ” do not accord with the two major conditions for the formation of heteromorphism relations. This paper argues that the auxiliary word “” in Korean is hard to think of as " Morphological morphology, they are treated as different morphological but more appropriate.
