Structural particle 的/得/地 ("de")

的、得、地是汉语中三个重要的结构助词，都读作轻声'de'，但用法不同。'的'用于定语和名词之间，表示修饰关系；'得'用于动词或形容词后，连接补语；'地'用于状语和动词之间，表示修饰关系。

的, 得, and 地 are three important structural particles in Chinese, all pronounced as neutral tone 'de', but with different uses. '的' is used between an attributive and a noun to indicate modification; '得' is used after a verb or adjective to connect a complement; '地' is used between an adverbial and a verb to indicate modification.

的使用：'的'用于定语（如形容词、名词、代词等）和名词之间，例如'漂亮的花'。'得'用于动词或形容词之后，引入结果、程度、状态等补语，例如'跑得很快'。'地'用于状语（如副词、形容词等）和动词之间，例如'高兴地笑了'。注意：在口语中有时通用，但书面语需区分。

的: Used between an attributive (e.g., adjective, noun, pronoun) and a noun, e.g., 'beautiful flower'. 得: Used after a verb or adjective to introduce a complement of result, degree, state, etc., e.g., 'run very fast'. 地: Used between an adverbial (e.g., adverb, adjective) and a verb, e.g., 'laughed happily'. Note: In spoken language they are sometimes interchangeable, but written Chinese requires distinction.
