 英语三大构词法


据统计,在莎士比亚时代,英语单词总量大约为十四万个,而到了伊丽莎白二世时期,英语单词量已经达到三十三万个,而现在,英语单词量竟然以超过百万。那么,单词量的核裂变似的增长,是一种疯狂的、毫无逻辑的野蛮生长,还是有章可循呢?事实上,英语单词的变化,经历了以下几个阶段,而这些变化,在当今,依旧为英语单词的丰富而贡献着力量。我们就一起来学习一下主流的英语构词法:
在悠久的英语语言变迁中,单词的产生与丰富主要源于以下三种构词方法:compounding合成法;conversion转换法;derivation派生法。
compounding 合成法
合成法是把两个或两个以上的单词合成一个新单词的构词法。有的可以直接写在一起构成一个新单词,还有的在词与词之间用连字符“-”构成一个新单词,这个词叫做复合词。
