There are three particles for modifying words in Chinese - 的, 得 and 地.
的 is used for modifying nouns. It can come after an adjective to describe a noun, or after another noun to indicate possession, similar to the “'s” in English. For example:
安靜的圖書館,露西的廚房。
得 is used for modifying verbs. It usually comes after a verb to modify it or to signify an outcome. It usually comes in the form of: verb + 得 + adjective. For example:
她唱得很好,我看得見他。
地 is used to transform adjectives into adverbs. It is similar to the “-ly” suffix in English. Oftentimes, adjectives are repeated twice. For example:
快快地跑,難過地哭。
