| Euphemism as a universal linguistic phenomenon and the visualization of the social culture plays an important role in our daily life. With the development of the society and science, euphemism has become"the lubricant in communication". The Euphemism is a specific language pheromone along with the development of human being's civilization. There must be some relevant cognitive rules behind this new pattern of language pheromone which will do benefit to the communication by employing these rules. This thesis will further study euphemism and its generating mechanism and meaning construction within the framework of conceptual integration theory.The previous studies on euphemism involve various theoretical perspectives such as rhetoric, semantics, psycholinguistics, sociolinguistics, cross-cultural communication and pragmatics. In the late 90th of the last century, scholars noticed that the conceptual integration theory provided a good approach in cognitive linguistic area to explain our language phenomenon. Conceptual integration theory is an important component of cognitive linguistics, which gives a new point of view to explain the building of cognitive model from a mental space, conceptual integration network, and a total of space, the input space, mapping, relationship and compression, as well as the mechanism of meaning construction. It can not only be used to explain the semantic understanding of euphemism, also to explain our understanding of the world which carries out a fundamental way of thinking.Conceptual integration theory is the continuousness of mental space and the important component of cognitive linguistic. This thesis will further study euphemism and its generating mechanism and meaning construction within the framework of conceptual integration theory. The authors will introduce the basic concepts of Euphemisms and theory, including the definition of euphemism, characteristics, classification and function, etc., which based on the concept of integration theory and try to explain the mechanism and significance of meaning construction from the perspective of the conceptual integration network. |
