I. Introduction
In America, more and more people are partial to using slang in their daily life communication and writing technique. In the past, people’s impression of slang may slang be that slang is rude, dirty and indecent; but today, as a highly colloquial speech, slang has become the most colorful and vivid member of the family of languages. “The vocabulary of an ordinary America generally is estimated at 10,000---20,000 words.according to my conservative estimation about 2,000 words are slang.”(Chapman, Red.4) The number shows the important status of slang in American English, therefore we should eliminate the traditional bias of slang. Slang is popular in America because of its freshness, lifelikeness, humor, and it is an effective way of communication; at the same time, it also carries strong cultural implications of America because most slang words come from each sub-cultural group, which reflect their actual life. “it is impossible to acquire a thorough knowledge of English (or of any other language, for that matter ) without being familiar with slang and vulgarism. Whoever is uninitiated.will be at a loss to understand many of the masterpieces of English literature? Nay.he will scarcely be able even to understand an English newspaper.” (Partridge.73) As it were, an English learner can not communicate with foreigners at their pleasure without much understanding in American slang. From this point, slang is a bridge for English learners to make up the cultural gap, so we should know and treat slang with a correct attitude. There are no such things as good or bad, right or wrong in language. As a special form of language, its existence is a kind of outcome of culture and history. This paper starts with the definition of slang; introduces its sources of slang and characteristics; expounds its causes of development. Finally it emphatically analyzes the morphological characteristics of American slang. American slang can be used as a mirror reflecting American society, and can help us to understand American language and social culture so that the goal of English language learning can be achieved. 英文论文论美国俚语的构词特点:http://www.youerw.com/yingyu/lunwen_16827.html
