Take an ordinary attributive phrase like 红的车 ("the red car") and simply delete the noun: 红的. What's left is no longer a modifier hanging in the air — it becomes a noun in its own right, meaning "the red one." 大的 is "the big one," 便宜的 is "the cheap one(s)," 我要小的 is "I want the small one." This is 的 in its nominalizing role: it packages the adjective into a thing. For English speakers the key insight is that Chinese needs no separate word for "one/ones" — the 的 already is the noun. Where English says "the red one," Chinese says just 红的, and adding an extra word is exactly the mistake to avoid.
Deleting the noun: 的 becomes "the … one"
Whenever context makes the noun obvious — you're both looking at a rack of clothes, a bowl of apples, a shelf of cups — you drop it and let the adjective + 的 stand alone:
| Full phrase | Noun dropped | Meaning |
|---|---|---|
| 红的车 (hóng de chē) | 红的 (hóng de) | the red one |
| 大的苹果 (dà de píngguǒ) | 大的 (dà de) | the big one |
| 便宜的东西 (piányi de dōngxi) | 便宜的 (piányi de) | the cheap one(s) |
| 小的杯子 (xiǎo de bēizi) | 小的 (xiǎo de) | the small one |
| 新的手机 (xīn de shǒujī) | 新的 (xīn de) | the new one |
这两件衣服，我要红的。
zhè liǎng jiàn yīfu, wǒ yào hóng de
Of these two pieces of clothing, I want the red one.
苹果有大的有小的，你要哪个？
píngguǒ yǒu dà de yǒu xiǎo de, nǐ yào nǎ ge
Some of the apples are big and some are small — which do you want?
太贵了，有没有便宜一点的？
tài guì le, yǒu méiyǒu piányi yìdiǎn de
Too expensive — is there a slightly cheaper one?
No word for "one" — the 的 IS the noun
This is where English habits mislead. "The red one," "the big ones," "a cheap one" all carry a placeholder noun that Chinese refuses. 的 already nominalizes, so 红的 by itself is complete. It is also number-neutral — 大的 can be "the big one" or "the big ones," decided by context, not by a plural marker:
新的比旧的好，可是也贵不少。
xīn de bǐ jiù de hǎo, kěshì yě guì bù shǎo
The new ones are better than the old ones, but they cost quite a bit more.
这几个杯子里，蓝的是我的。
zhè jǐ ge bēizi lǐ, lán de shì wǒ de
Among these cups, the blue one is mine.
菜单上这两道，我不吃辣的。
càidān shàng zhè liǎng dào, wǒ bù chī là de
Of these two on the menu, I don't eat the spicy one.
That second example hides a bonus: 我的 ("mine") is the very same construction — a nominalized 的 phrase where the "modifier" is a possessor instead of an adjective. Chinese builds "mine," "the red one," and "the ones that are good" all on one machine.
The same 的: 卖菜的 "the one who sells vegetables"
Nominalizing 的 isn't limited to adjectives. Put a whole verb phrase in front of it and you get a "the one that/who …" noun. 卖菜的 (mài cài de) is literally "sell-vegetables 的" — "the vegetable seller." 开车的 is "the driver," 说话的 is "the one who's talking." It's the same delete-the-noun logic scaled up from adjectives to clauses, which is why this page sits next to 的 nominalization and the de relative clause.
门口那个卖菜的是我邻居。
ménkǒu nà ge mài cài de shì wǒ línjū
That vegetable seller at the gate is my neighbor.
穿红衣服的是我姐姐。
chuān hóng yīfu de shì wǒ jiějie
The one wearing red is my older sister.
If you want the full modifier-plus-noun version instead — 红色的车 "the red car" — that's the ordinary attributive 的; here we've simply left the noun off.
Common Mistakes
1. Adding a word for "one." English "one/ones" has no Chinese equivalent — the 的 already is the noun.
❌ 我要红的一个。
Incorrect — no word for 'one' is needed; say 我要红的.
✅ 我要红的。
wǒ yào hóng de
I want the red one.
2. Bolting on a redundant noun like 颜色. For "the red one," don't append 颜色 ("color") — that changes the meaning to "the color red."
❌ 这两件，我要红的颜色。
Wrong sense — 红的颜色 means 'the color red'; for the red item say just 红的.
✅ 这两件，我要红的。
zhè liǎng jiàn, wǒ yào hóng de
Of these two, I want the red one.
3. Dropping the 的 as well. A bare adjective can't stand in for a noun; the 的 is what nominalizes it.
❌ 太大了，我要小。
Incorrect — a bare adjective isn't a noun; you need 的: 我要小的.
✅ 太大了，我要小的。
tài dà le, wǒ yào xiǎo de
It's too big — I want the small one.
4. Forcing 一个 in front of the 的 phrase. The 的 phrase is already a full noun; you don't need a measure phrase unless you're genuinely counting.
❌ 有免费的一个吗？
Unnatural — say 有免费的吗; the 的 phrase already names the thing.
✅ 有免费的吗？
yǒu miǎnfèi de ma
Is there a free one?
Key Takeaways
- Delete the noun after adjective + 的 and the phrase becomes a noun: 红的 "the red one," 大的 "the big one."
- 的 nominalizes — there is no separate word for "one/ones." 红的 is already complete.
- It's number-neutral: 大的 = "the big one" or "the big ones," from context.
- The same 的 nominalizes possessors (我的 "mine") and whole verb phrases (卖菜的 "the vegetable seller").
- Don't add 一个, 东西, 颜色, or a word for "one" — and don't drop the 的 itself.

- 的 Nominalization (红的, 我买的)HSK 2 — Drop the noun after 的 and the 的-phrase itself becomes the noun: 红的 'the red one', 我的 'mine', 吃的 'things to eat', 卖菜的 'the vegetable seller' — 的 turns any modifier or clause into a stand-alone noun.
- Attributive Adjectives with 的HSK 1 — To put an adjective in front of a noun, Chinese links the two with 的: 漂亮的花 'a pretty flower', 红色的车 'a red car', 很好的朋友 'a good friend'. 的 is the adjective-to-noun glue, and a modified adjective almost always requires it.
- Color WordsHSK 1 — Chinese colors — 红 (red), 蓝 (blue), 黄 (yellow), 绿 (green), 黑 (black), 白 (white) — are adjectives that predicate directly with 很, take 色 to name the color (红色), and attach to nouns with 的 (红色的车).
- 的 in Relative ClausesHSK 3 — A whole clause + 的 modifies a noun — doing the job of English who/that/which — but the clause comes BEFORE the noun: 我买的书 'the book I bought', 昨天来的人 'the person who came yesterday'. Chinese relative clauses are head-final.
