Euphemism is a common linguistic phenomenon in different cultures. It is deeply rooted in social life and it strongly reflects social values and cultural values. We have heard euphemism in the movies and television programs. We have read it in magazines and newspapers. We have relished it in works of superb writers. We have overheard it on street comers and park benches all over the world. As a very part of language and a common linguistic phenomenon, euphemism is also a common language strategy in communication. Almost everyone makes use of euphemisms consciously in some situations where they feel difficult, or embarrassed, or unsuitable to talk about something directly. People use them with various intensions as well as for various purposes. Actually, euphemisms have been playing a role as a kind of “lubricants” in daily communication and the exchange of information.
