许多英语单词的构成都有一定的规律,这种规律被称为构词法。掌握构词法知识对我们更好地理解词义、认识新词和扩大词汇量都有重要意义。英语中的构词法有合成法、派生法和转化法三大类。一、合成法由两个或两个以上的单词合成的词叫合成词,这种构词法称为合成法。最常见的合成法包括:合成名词、合成形容词、合成动词。词与词之间有的用连字符连接,有的直接连接在一起。

三、转化法(cnversin) 在词形不变的情况下,把一个单词由一种词性转换成另一种词性,而没有加任何词缀,这种构词方法称为转化法。转化法种类很多,但数量最多的是由名词转化为动词和由动词转化为名词两大类。转换后的词义与转换前的词义通常有密切的联系,但有时差异也很大。例如:dream v.做梦→n.梦lk v.看→n.相貌back n.后背→v.支持air n.空气→v.通风
