Why 很? Adjectives Without 是 in Chinese

In Mandarin, an adjective can serve as the whole predicate with no verb “to be” at all, and the ordinary way to say it is with 很: 他很高 (Tā hěn gāo), “He is tall.” You do not say 他是高 in a plain description. The 很 here is mostly a linker that makes a plain description sound complete, and in an unstressed sentence it carries little of the meaning “very”.

That single habit explains most of the confusion, so the rest of this guide sorts out when 很 appears, when it disappears, and where 是 genuinely belongs near an adjective.

Adjectives in Chinese behave like verbs

English needs “is” because “tall” cannot be a predicate by itself. Chinese adjectives can. Grammarians often call them stative verbs, because 高 already means “be tall” the way 跑 means “run”. So the word order is simply subject plus predicate:

Chinese	Pinyin	English
今天很熱。	Jīntiān hěn rè.	It is hot today.
她很忙。	Tā hěn máng.	She is busy.
這個很貴。	Zhège hěn guì.	This one is expensive.
咖啡很好喝。	Kāfēi hěn hǎohē.	The coffee is good.

This is why 是 does not belong in these sentences. 是 equates two nouns, as in 她是老師 (Tā shì lǎoshī, “She is a teacher”). An adjective is not a noun, so 他是高 sounds broken.

✗ 他是高。

✗ 今天是熱。

Both are ungrammatical as plain descriptions.

What 很 actually does

Say the bare adjective on its own and the sentence sounds unfinished: 他高 (Tā gāo) leaves the listener waiting. Native speakers hear it as the first half of a contrast. 很 supplies the missing weight, and that is why textbooks call it the default linker.

The Taiwan MOE dictionary lists 很 as an adverb meaning 甚、非常, “to a high degree”, with examples such as 這主意很好. So the dictionary meaning is “very”. In everyday speech, though, an unstressed 很 in a simple statement is much lighter than English “very”. 她很忙 reads as “She is busy”. Stress it, and it becomes “She is very busy”.

If you want to be clearly stronger, choose another word:

• 非常 (fēicháng): 她非常忙, “She is extremely busy.”
• 真的 (zhēn de): 她真的很忙, “She really is busy.”
• 好 (hǎo) before an adjective, which the MOE dictionary glosses as 很、非常 with examples like 好冷: 今天好冷, “It’s so cold today.” In Taiwan this is very common in speech.
• 超 (chāo), a casual spoken intensifier, common among younger speakers: 超貴. Dictionaries do not yet list it in this sense, so keep it for informal speech.
• 蠻 (mán) or 滿 (mǎn) for “quite”: 蠻好的, 滿不錯的. The MOE dictionary glosses 蠻 as 很、挺、十分 with the example 蠻好的. This is the everyday Taiwan way to say “quite good”.

When the adjective stands alone

The bare adjective is fine in three situations.

Contrast

Two things set side by side need no 很:

• 這個貴，那個便宜。 Zhège guì, nàge piányi. “This one is expensive; that one is cheap.”
• 哥哥高，弟弟矮。 Gēge gāo, dìdi ǎi. “My older brother is tall; my younger brother is short.”

The contrast does the job that 很 would do.

Negatives

不 replaces 很 completely:

• 他不高。 Tā bù gāo. “He is not tall.”
• 這個不貴。 Zhège bú guì. “This one is not expensive.”

The pinyin shows bú guì because 不 changes to bú in front of a fourth tone. For “not very”, use 不太: 他不太高 (Tā bú tài gāo), “He is not very tall”.

Questions

The yes-no form 你忙嗎？ (Nǐ máng ma?) and the choice form 你忙不忙？ (Nǐ máng bu máng?, with a light 不) both take the bare adjective. A reply is naturally 我很忙 (Wǒ hěn máng) or the shorter 不忙 (bù máng).

Why comparisons drop 很

In a 比 comparison, the adjective follows 比 plus the thing compared, with no 很:

• 他比我高。 Tā bǐ wǒ gāo. “He is taller than I am.”
• 這家店比那家店便宜。 Zhè jiā diàn bǐ nà jiā diàn piányi. “This shop is cheaper than that one.”

✗ 他比我很高。

The last sentence is ungrammatical. 比 sentences do not take degree adverbs such as 很 or 非常 before the adjective. To strengthen the comparison, use 更 or 還 before the adjective: 他比我更高 (Tā bǐ wǒ gèng gāo) or 他比我還高 (Tā bǐ wǒ hái gāo), “He is even taller than I am”. Or put an amount after the adjective: 他比我高很多 (Tā bǐ wǒ gāo hěn duō), “He is a lot taller than me”, or 高一點 (gāo yìdiǎn), “a bit taller”. In 高很多, the 很 modifies 多. The full set of comparison patterns is in Chinese comparison sentences with 比.

When 是 does appear with an adjective

There are three real cases, and learners often mix them up.

是 + adjective + 的

這個菜是辣的。 Zhège cài shì là de. “This dish is a spicy one.” Here 的 turns the adjective into a noun phrase (“a spicy one”), and 是 then links two nouns. It sounds like a statement of classification or a correction, as in “This dish is spicy (the spicy kind)”. 這件衣服是新的 (Zhè jiàn yīfu shì xīn de) works the same way: “This garment is a new one”.

Compare the plain version, 這件衣服很新, which simply describes it.

Stressed 是 + 很 + adjective

Say 是 with stress in front of 很 and an adjective, and you confirm a point before adding a contrast: 他是很高，可是不會打籃球 (Tā shì hěn gāo, kěshì bú huì dǎ lánqiú), “He is tall all right, but he can’t play basketball.” This is a spoken emphasis pattern, and it is the reason you will sometimes hear 是 before an adjective. In a neutral description, still leave it out.

The emphasis pattern 是…的

The 是…的 construction puts focus on a detail of a past event, such as when or how it happened: 他是昨天來的 (Tā shì zuótiān lái de), “It was yesterday that he came.” This is a different structure from the one above, and the adjective is not involved. It has its own page, 是…的 construction.

A note on verbs of feeling

很 also goes before verbs that express feelings and attitudes, which is the same “degree” job:

• 我很喜歡這家餐廳。 Wǒ hěn xǐhuān zhè jiā cāntīng. “I like this restaurant a lot.”
• 我很想你。 Wǒ hěn xiǎng nǐ. “I miss you very much.”

The MOE dictionary’s own example for 很 is 他很喜歡看書, “He likes reading a lot”, so this use is fully standard.

A short practice routine

1. Take five adjectives you already know: 大, 小, 貴, 忙, 累.
2. Make three sentences with each: one with 很, one with 不, one in a contrast pair.
3. Make one 比 sentence with each, and check that no 很 sits before the adjective.

Where 很 sits within the larger sentence is covered by Mandarin sentence structure.
