In addition, many linguists think that the definition of euphemism should be defined in a narrow and broad sense。 For example, Leech thinks that euphemism is used to replace the offensive words in order to make it sound more pleasant and polite。 It is easily seen that Leech attributes the unpleasantness of words to their connotative meanings viewed from the semantic perspective, which are called euphemism in the narrow sense。 For example, we always say “golden age” for “old” and “the black one” for “devil” and so on。 However, Linguist may pay attention to the grammatical ways that form euphemism, such as negation, mood, voice, tense…。 This function is used in a communicative event in order to reach the certain purposes。 Euphemism of this type is called in the broad sense。 For example, if someone says “it seems that what you said dose not match the truth”, which could be understood as “I think you told a lie”。 To sum up, we could have a better understanding of euphemism through its narrow and broad sense。 And euphemism is an effective and roundabout language expression that could substitute the offensive to realize the expecting results in the social communication。 文献综述
