1、定语从句在复合句中修饰某一名词、代词或句子的从句叫定语从句。引导定语从句的词叫关系词，被定语从句修饰的词叫先行词。关系词在定语从句中的作用主要是：引导定语从句并且在定语从句中充当一定的成分。引导定语从句的关系词分为关系代词和关系副词两类。关系代词主要有that, which, who, whom, whose, as等；关系副词主要有when, where, why等。关系代词在定语从句中主要充当主语、宾语、表语、定语等成分，而关系副词则主要在定语从句中充当状语。定语从句分为两大类，即限制性定语从句和非限制性定语从句。限制性定语从句是对先行词的修饰或限定；非限制性定语从句是对先行词的补充说明。
