Mandarin Adjectives Before Nouns: When to Use 的 (de)
By Michael McGettrick and Wee Khang LinUpdated 11 October 2026
Before a noun, a short common adjective goes straight on: (dà fángzi), a big house. Anything longer or modified takes (de): (hěn dà de fángzi), a very big house. This page is the companion to adjectives without 是, which covers adjectives after the noun.
Quick check
Three quick questions on what you have just read. The full practice is further down.
Pick the right one
0/3Does this phrase take 的 (de)? Pick the everyday form.
大 房子 (a big house)
dà ___ fáng zi (a big house)
很大 房子 (a very big house)
hěn dà ___ fáng zi (a very big house)
新 车 (a new car)
xīn ___ chē (a new car)
The rule on one screen
The colour marks (de) wherever it is needed:
| Adjective | Hanzi | Pinyin | English |
|---|---|---|---|
| One syllable | | dà fángzi | a big house |
| With or | | hěn dà de fángzi | a very big house |
| Two syllables | | hǎokàn de shū | a good read |
| No noun after it | | dà de | the big one |
| (many) | | hěn duō rén | many people |
One syllable: straight onto the noun
A common one-syllable adjective attaches directly, with nothing in between:
| Hanzi | Pinyin | English |
|---|---|---|
| dà fángzi | a big house |
| xīn chē | a new car |
| hǎo rén | a good person |
| xiǎo māo | a little cat |
In a sentence, the pair sits where any noun would:
。(Tā yǒu yí liàng xīn chē.) - He has a new car.
Adding (de) here is not wrong, but it puts weight on the adjective, as if picking this one out from others:
，。(Wǒ yào dà de fángzi, bú yào xiǎo de.) - I want the big house, not the small one.
With 很 (hěn) or 非常 (fēicháng): always 的
Once a degree word sits in front of the adjective, (de) is compulsory:
| Hanzi | Pinyin | English |
|---|---|---|
| hěn dà de fángzi | a very big house |
| hěn guì de shǒujī | a very expensive phone |
| fēicháng hǎo de péngyou | a really good friend |
。(Tā shì yí ge hěn hǎo de lǎoshī.) - He's a very good teacher.
, with the (hěn) and no , is the commonest slip on this page.
Two syllables: usually 的 (de)
Two-syllable adjectives usually take (de):
| Hanzi | Pinyin | English |
|---|---|---|
| hǎokàn de shū | a good read |
| piàoliang de yīfu | pretty clothes |
| hǎochī de cài | tasty food |
A few everyday pairs drop it in speech, such as (piàoliang yīfu). Learn those as you meet them; with (de) you are never wrong.
大的 (dà de): the big one
Leave the noun out and adjective + (de) means "the ... one":
。(Wǒ yào dà de.) - I'll have the big one.。(Hóng de shì wǒ de.) - The red one is mine.
The noun is understood from what you are both looking at, exactly like English "one".
The exception: 很多 (hěn duō), many
(hěn duō) counts rather than describes, so it goes straight onto the noun like a number:
。(Wǒ yǒu hěn duō péngyou.) - I have lots of friends.
Bare (duō) does not mean "many" in front of a noun: "many people" is (hěn duō rén), never .
Mistakes English speakers make
| Wrong | Right | Why |
|---|---|---|
| | (hěn) + adjective needs (de) |
| | "many" before a noun is (hěn duō) |
。 | 。 | "the big one" needs (de) |
Adjectives before nouns, with and without (de), are on the AQA GCSE Chinese specification at Foundation and Higher tier.
What to do next
- Do the drill below.
- Read adjectives without 是 for the adjective after the noun.
- Then possession with 的 for
(de) after a person:(wǒ de shū), my book.
