In foreign countries, the English famous phonetician D. Jones realized the vague attribute of language early in 1957. In 1965, professor Zadeh in the University of California most early proposed the vague theory in his essay called “Fuzzy Set” published in the magazine named Information and Control and started the new discipline of vagueness language. In China, professor Wu in Beijing Normal University first researched the vague attribute of language using vague theories in his thesis called “The Primary Research of Vague Language in 1979 and wrote the book of Vague Linguistics, thus he started the fuzzy linguistics of China, which symbolize the birth of vague linguistics in China. Nowadays, vagueness is widely used in all areas such as law, economy, and teaching. Business correspondence characterized by the correctness of language, the clearness and orderliness of logic of thinking, the preciseness of structure are no exception. Vague language transmits information using vagueness in itself, the uncertainty of which is often expressed by the way of implicitness, objectivity, preciseness, and politeness, these features can improve the communicative effect. To some extent, vagueness plays an irreplaceable role in English business correspondence. The appropriate use of the language policy tools or skills can help us to achieve the optimal relevance. Using the framework of relevant theory, this paper tres to discuss the phenomenon of vagueness in English business correspondence. Based on the real correspondence, the paper also analyzes how the senders select and use vague language to achieve optimal relevance, in order to achieve successful communication purpose.Chapter One Literature Review In this chapter, the author firstly have a brief introduction of business English correspondence.
