If you pick up any Chinese book, article, or subtitle file, the character you will see most often is 的 (de). In fact, statistically, it accounts for roughly 3-4% of all characters used in modern texts.
For HSK learners, 的 is the glue that holds Mandarin sentences together. While beginners learn it as "apostrophe-s" (possessive), its function goes far beyond simple ownership. It connects descriptions to nouns, turns verbs into nouns, and creates complex relative clauses.
In this guide, we will break down the three core pillars of Using the Structural Particle 的 (de) to help you level up from basic phrases to fluid HSK 4+ sentence structures.
Core Function 1: Possession (The Owner’s Tag)
The most intuitive use of 的 aligns closely with the English "apostrophe-s" or "of." It connects the "Owner" to the "Possession."
Formula: [Owner] + 的 + [Possession]
- Example (HSK 1): 我的老师 (Wǒ de lǎoshī) — My teacher.
- Example (HSK 2): 公司的经理 (Gōngsī de jīnglǐ) — The company’s manager.
Pro Tip: If you struggle with pronouns, review our beginners guide to Chinese pronouns to ensure your foundations are solid before adding possession markers.
Core Function 2: Modification (The Descriptive Glue)
In English, we can put an adjective directly before a noun: "The red apple." In Chinese, if that adjective consists of two or more syllables, you generally need "glue" to stick it to the noun.
Formula: [Adjective/Description] + 的 + [Noun]
- Multisyllabic Adjective: 漂亮的衣服 (Piàoliang de yīfu) — Beautiful clothes.
- Noun acting as Adjective: 木头的桌子 (Mùtou de zhuōzi) — Wooden table.
This is essential for HSK 3 descriptive writing. If you leave out the de, sentences can sound choppy or incorrect.
Core Function 3: Relative Clauses (The Secret to HSK 4)
This is the hardest concept for English speakers. In English, we use "who," "that," or "which" after the noun. (e.g., "The man who bought the car").
In Chinese, everything goes before the noun, connected by 的.
Formula: [Complex Action/Phrase] + 的 + [Main Noun]
- English: The fruit [that I bought yesterday].
- Chinese: [我昨天买] 的 水果 (Wǒ zuótiān mǎi de shuǐguǒ).
- Literal translation: [I yesterday bought] 's fruit.
Understanding this structure is vital for passing the HSK reading section. It allows you to parse long sentences by finding the main noun first.

Core Function 4: Nominalization (The "One")
What if the context is clear and you want to drop the noun? 的 can turn an adjective or verb into a noun entity, similar to saying "The big one" or "The red one."
Structure: [Description] + 的
- Context: Shopping for shoes.
- Sentence: 我要黑色的。(Wǒ yào hēisè de.)
- Translation: I want the black one.
This nominalization is heavily tested in HSK 4. It implies "the thing associated with [description]."
- 吃的 (Chī de) = "Things to eat" (Food).
- 用的 (Yòng de) = "Things to use" (Supplies).
When to Omit 的 (The Exception Rules)
One mark of a native speaker is knowing when not to use grammar particles. You can—and should—drop 的 in two specific situations.
1. Close Personal Relationships
When talking about family or intimate connections, adding 的 sounds distant or robotic.
- Natural: 我妈妈 (Wǒ māma) — My mom.
- Unnatural: 我的妈妈 (Wǒ de māma).
- Natural: 我家 (Wǒ jiā) — My home.

2. Monosyllabic Adjectives
If the adjective is only one character, you usually stick it directly to the noun.
- Correct: 好人 (Hǎo rén) — Good person.
- Incorrect: 好的人 (Hǎo de rén).
- Correct: 红苹果 (Hóng píngguǒ) — Red apple.
Addressing the "De" Confusion
In HSK studies, you will encounter the "De Trio." While they all sound the same (de - neutral tone), they are written differently and have distinct grammatical roles.
| Character | Function | Connection |
|---|---|---|
| 的 (de) | Attribute/Possessive | Noun connector |
| 得 (de) | Potential/Degree | Verb helper |
| 地 (de) | Adverbial | " -ly" ending |
This article focused strictly on 的 (The Noun Modifier). However, to pass HSK 5, you must distinguish between them perfectly. You can read a dedicated breakdown of these differences in our post on Mastering the De Particle.
Conclusion: Making Sentences Stick
The particle 的 (de) is your best friend. It allows you to build sophisticated descriptions, take ownership of items, and describe the world with color and detail.
Quick Study Checklist:
- Is there a multi-syllable adjective describing a noun? Add 的.
- Is there a complex phrase ("The book I wrote") modifying a noun? Add 的.
- Are you talking about your mom? Drop the 的.
Keep an eye out for 的 in your reading practice exercises. Circle it and ask yourself: "Is this possession, modification, or a relative clause?" Decoding it this way will dramatically improve your comprehension speed.
Usage Check: Are you saying "Red apple" (红苹果 - No de) or "Delicious apple" (好吃的苹果 - Use de)?
Happy Studying!
