歧义作为一种普遍语言（ｌｉｎｇｕｉｓｔｉｃ　ｕｎｉｖｅｒｓａｌ）现象存在于一切自然语言中，它的存在给语言交际设置了一定的障碍。然而，本文认为歧义应按其产生的目的和动机，分主观歧义和客观歧义，还认为主观歧义具有很高的实用价值。巧妙地制造并利用主观歧义不仅仅是一种积极的、富有创造性的语言运用手段，而且能够获得不同凡响的效果。因此本文对它的实用价值进行了粗浅的探讨。 Ambiguity, as a linguistic universal phenomenon, exists in all natural languages ​​and its existence has set some obstacles in the communication of language. However, this paper argues that ambiguity should be divided into subjective ambiguity and objective ambiguity according to its purpose and motivation, and it also holds that subjective ambiguity has very high practical value. Subtly creating and using subjective ambiguity is more than just a positive, creative means of language use, but also gives extraordinary results. Therefore this article has carried on the shallow discussion to its practical value.
