The attributive 的 frame — modifier + 的 + noun — is the default, but Chinese has an important escape hatch: in tight, everyday pairings the 的 is dropped. 我妈 (my mom), not 我的妈; 我们学校 (our school), not 我们的学校; 好人 (a good person), not 好的人. Two forces license the omission: intimacy (things close to you — family, home, your school, your workplace) and lexicalisation (a modifier + noun so common it has fused into a set phrase). Knowing when to drop 的 is a real marker of fluency, because inserting it where a native drops it — 我的妈 in casual talk — can sound stiff, distancing, or oddly emphatic.
Close relations and in-groups: 我妈, 我们学校, 你家
When a pronoun possesses something close to the speaker — a family member, one's own home, the school or company one belongs to — the 的 is normally left out. The relationship is felt as inalienable, part of you, so no explicit linker is needed.
| With 的 dropped | Category | Meaning |
|---|---|---|
| 我妈 (wǒ mā) | close kin | my mom |
| 你家 (nǐ jiā) | home | your home / place |
| 我们学校 (wǒmen xuéxiào) | in-group institution | our school |
| 我们公司 (wǒmen gōngsī) | in-group institution | our company |
| 我朋友 (wǒ péngyou) | close person | my friend |
我妈今天做了红烧肉。
wǒ mā jīntiān zuò le hóngshāoròu
My mom made braised pork today. (informal) — kin term, no 的.
我们学校有三个食堂。
wǒmen xuéxiào yǒu sān ge shítáng
Our school has three cafeterias. (informal) — in-group institution drops 的.
你家离这儿远吗？
nǐ jiā lí zhèr yuǎn ma
Is your place far from here? (informal) — 你家, not 你的家.
我朋友下周要结婚了。
wǒ péngyou xià zhōu yào jiéhūn le
My friend is getting married next week. (informal) — a close person: 我朋友.
Why does closeness license the drop? Cross-linguistically, languages tend to mark inalienable possession — kin, body parts, one's own group — more lightly than ordinary "things I happen to own." Chinese follows the same instinct: your mother, your home, your school are felt as extensions of you, not as separate objects that need an explicit of-link. A phone or a computer is an ordinary possession and keeps 的; a mother is not, so it drops. This is also why 我的妈 can be read as emphatic or even sarcastic — spelling out the link foregrounds a connection that is normally taken for granted.
Monosyllabic adjective + noun set phrases: 好人, 大城市
The second drop zone is the bare single-syllable adjective fused with a noun into a fixed expression. 好人 (good person), 大城市 (big city), 热水 (hot water), 新车 (new car): these behave almost like compound words, and inserting 的 breaks them up unnaturally.
他是个好人，你可以信任他。
tā shì ge hǎorén, nǐ kěyǐ xìnrèn tā
He's a good person, you can trust him. (neutral) — 好人, a bare monosyllable + noun.
上海是个大城市，节奏很快。
Shànghǎi shì ge dà chéngshì, jiézòu hěn kuài
Shanghai is a big city, the pace is fast. (neutral) — 大城市, no 的.
天冷了，我想喝点热水。
tiān lěng le, wǒ xiǎng hē diǎn rè shuǐ
It's gotten cold — I'd like some hot water. (informal) — 热水, a set pairing.
The key restriction: this only applies to a single-syllable, unmodified adjective. The moment the adjective gains a syllable (漂亮) or a degree word (很好, 非常大), the 的 comes back — see dropping 的 with monosyllabic adjectives for the fine print.
他是我很好的朋友。
tā shì wǒ hěn hǎo de péngyou
He's a very good friend of mine. (neutral) — 很好 is modified, so 的 returns: 很好的朋友.
The dividing line: what still needs 的
Everything longer or heavier keeps its 的. Ordinary (non-intimate) possession, disyllabic adjectives, degree-modified adjectives, and phrases all require the linker. When in doubt, keep 的 — over-dropping is the more common and more jarring error.
这是我的电脑，那台是公司的。
zhè shì wǒ de diànnǎo, nà tái shì gōngsī de
This is my computer, that one is the company's. (neutral) — ordinary possession keeps 的.
我买了一件很漂亮的裙子。
wǒ mǎi le yí jiàn hěn piàoliang de qúnzi
I bought a very pretty skirt. (informal) — modified, disyllabic adjective: 的 stays.
Common Mistakes
1. Dropping 的 after a modified adjective. Once 很 (or another degree word) is present, the drop is no longer allowed.
❌ 他是我很好朋友。
Incorrect — 很好 is modified, so it needs 的: 很好的朋友.
✅ 他是我很好的朋友。
tā shì wǒ hěn hǎo de péngyou
He's a very good friend of mine. — 很好的朋友.
2. Dropping 的 after a two-syllable adjective. The set-phrase drop is only for single-syllable adjectives.
❌ 我买了一件漂亮裙子。
Incorrect — disyllabic 漂亮 keeps 的: 漂亮的裙子.
✅ 我买了一件漂亮的裙子。
wǒ mǎi le yí jiàn piàoliang de qúnzi
I bought a pretty skirt. — 漂亮的裙子.
3. Keeping 的 in a close-relation phrase. Native speech omits 的 with close kin and in-groups; keeping it sounds distancing.
❌ 我的妈今天做了红烧肉。
Unnatural in casual speech — with a kin term the 的 is dropped: 我妈.
✅ 我妈今天做了红烧肉。
wǒ mā jīntiān zuò le hóngshāoròu
My mom made braised pork today. — 我妈, no 的.
4. Inserting 的 into a nationality/set compound. 中国人 (a Chinese person) is a fused compound; 中国的人 shifts the meaning to "people (who are) from China."
❌ 他是中国的人。
Unnatural for 'a Chinese person' — the compound is 中国人; 中国的人 means 'people from China' as a phrase.
✅ 他是中国人。
tā shì Zhōngguórén
He's Chinese. — 中国人, a set compound with no 的.
Key Takeaways
- Drop 的 with close relations and in-groups: 我妈, 你家, 我们学校, 我们公司, 我朋友.
- Drop 的 with a bare single-syllable adjective + noun set phrase: 好人, 大城市, 热水, 新车.
- Keep 的 for ordinary possession (我的电脑), disyllabic adjectives (漂亮的), and any degree-modified adjective (很好的).
- The forces at work are intimacy and lexicalisation — the tighter and more habitual the pairing, the more likely 的 vanishes.
- When unsure, keep 的: over-dropping (很好朋友, 漂亮裙子) is the more jarring mistake.

- 的 as Attributive / PossessiveHSK 1 — 的 (de) is the all-purpose linker that ties a modifier to the noun it describes — possession (我的书), a noun's property (老师的话), an adjective (漂亮的花) or a whole phrase (很贵的东西): modifier + 的 + noun.
- Dropping 的 with Monosyllabic AdjectivesHSK 2 — A bare one-syllable adjective often fuses straight onto a noun with no 的: 好人 'good person', 新车 'new car', 热水 'hot water'. But add anything — 很 or a second syllable — and 的 comes back: 很好的人.
- Possession with 的HSK 1 — Chinese builds possession with one particle, 的 (de), always in the order possessor-的-possessed: 我的书 (wǒ de shū, 'my book'), 老师的车 (lǎoshī de chē, 'the teacher's car'), 中国的历史 (Zhōngguó de lìshǐ, 'China's history') — the single 的 covers both the English possessive 's and the word 'of', and it also turns a bare pronoun into 'mine / yours / hers' (这是我的, 'this is mine').
- Ordering Multiple 的-PhrasesHSK 4 — When several modifiers stack before one noun they follow a fixed order — possessive/relative clause → demonstrative + number + measure → descriptive adjective → noun — and only some layers take 的: 我的那两本很有意思的书.
