Euphemism has the characteristics of being implicative and tactful. As the language signal, in the generation and translation process, it must go through a more complex and tortuous process of transformation because of its deep and potential meaning, so there are needs for more specific context of verbal information interpretation given by the speaker, however if only obtaining from the spoken language itself often cannot infer the speaker's real intention. So in order to understand euphemism better, a concentrated and effective study is needed.
