定语是修饰名词或代词的词语，提供更多信息来描述或限定它们的身份、特征、数量或关系。定语可以是形容词、名词、代词、数词、介词短语、动词不定式、分词（现在分词或过去分词）或整个定语从句。其主要作用是让名词或代词的含义更加具体和明确。
定语的类型及例子：
- 形容词定语
- Example: The red car is fast. (红色的车很快。)
- 名词作定语（名词短语）
- Example: A dog leash is needed for walking your pet. (遛狗需要一条狗绳。)
- 代词定语
- Example: Her books are on the shelf. (她的书在架子上。)
- 数词定语
- Example: Three apples fell from the tree. (三个苹果从树上掉下来。)
- 介词短语作定语
- Example: The book on the table is mine. (桌子上的书是我的。)
- 动词不定式作定语
- Example: I have a lot of work to do tonight. (今晚我有很多工作要做。)
- 分词作定语
- 现在分词： Example: The burning candle filled the room with light. (燃烧的蜡烛照亮了房间。)
- 过去分词： Example: The broken window needs to be fixed. (破碎的窗户需要修理。)
- 定语从句
- Example: The woman who spoke earlier is an expert in her field. (刚才说话的那位女士是她领域的专家。)
注意事项：
- 单词作定语一般放在名词前面；短语或从句作定语可置于名词之前或之后，长的定语从句通常放在名词之后。
- 当多个定语同时修饰一个名词时，一般遵循一定的语序规则，如形容词在名词前，介词短语和从句可能放在名词之后。
掌握定语的使用能够帮助你更准确、生动地描述事物，使语言表达更加丰富和具体。
