先行词是定语从句的引导词前面的被定语从句所修饰的名词、代词，在定语从句中充当一定的成分，我们可以这样认为，之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。

被定语从句修饰的词叫先行词, 先行词一般为人、物 或...具体的语言环境及词在句子中的地位和作用来实现它们的词类转化。... 先行词:fact, news,dea, thought, question, reply, report, remark等 引导定语从句的词叫关系词。关系词一般紧跟在先行词之后引导定语从句。定语从句都在它所修饰的先行词的后面(后置)。(这一点和汉语不同,汉语中的定语都放在被修饰的名词或代词的前面。) 先行:走在前面; 先进行；预先进行。英语句子由左(先，前)到右(后)。^O^
