好不 vs 好 (hǎo bù vs hǎo): the pseudo-negative intensifier
好不 (hǎobù) often functions as a pseudo-negative intensifier: it looks like “good not” but usually means “very” (e.g., 好不热闹 = very lively). However, it only works with a fixed set of adjectives and has an exceptional meaning in the phrase 好不容易 (with great difficulty). In contrast, 好 (hǎo) is a regular adverb meaning “very” that can be used with a wider range of adjectives. Choosing correctly requires knowing which adjectives accept the pseudo-negative pattern.
In Mandarin, 好不 (hǎobù) appears to be the negative counterpart of the degree adverb 好 (hǎo meaning “very”), but in many fixed expressions it loses its negative force and instead means “very” or “extremely”. This reversal only applies to a limited set of adjectives—mostly disyllabic ones expressing emotions or sensory impressions—such as 热闹, 痛快, 伤心. Outside these collocations, 好不 cannot be freely used as a negative; to say “not very” you need other structures like 不很 or 不太. The adverb 好 (hǎo) is simpler: it means “very” with any suitable adjective, e.g., 好漂亮 (very pretty), 好累 (very tired). The key learning challenge is memorizing which adjectives pair with the pseudo-negative 好不 and understanding that the meaning is opposite to the literal composition.
When to use each
好不 is used before a limited set of adjectives (mostly disyllabic) to express a high degree, often with a positive meaning despite the negative form. Common collocations include 好不热闹 (how lively), 好不痛快 (how pleasant), and 好不伤心 (how sad). The fixed phrase 好不容易 means “with great difficulty” (not “very easy”). Do not use 好不 freely with all adjectives; it is not a general intensifier for negation.
The pseudo-negative pattern is idiomatic and not productive. Many adjectives that can follow 好不 in the intensifying sense have a corresponding negative form that does not reverse meaning, e.g., 好不热闹 is the intensified version of 热闹 (lively), but a true negative like 不热闹 simply means “not lively”. Also, 好不 + adjective sometimes retains a literal negative meaning when the adjective is negative in nature, e.g., 好不自在 (very uncomfortable) where 不自在 is already negative.
好 is a degree adverb meaning “very” and can precede a wide range of adjectives (monosyllabic or disyllabic) to indicate a high degree. Examples include 好大 (very big), 好漂亮 (very pretty), and 好累 (very tired). It is more informal than 很 and is common in spoken Chinese. Unlike 好不, 好 does not carry a negative form; it is always positive in meaning.
好 as “very” is often used in exclamatory or emphatic contexts, e.g., 这个地方好美啊！(This place is so beautiful!). It can also be used with psychological verbs like 好想 (really want) but that usage is slightly different; in the intensifier sense, it attaches only to adjectives.

- 好不我好不容易才找到这个地方。Wǒ hǎobù róngyì cái zhǎodào zhège dìfang.I found this place with great difficulty.好不容易 is a fixed phrase meaning 'with great difficulty', not 'very easy'.
- 好这件衣服好漂亮！Zhè jiàn yīfu hǎo piàoliang!This dress is very pretty!好 + adjective works naturally; 好不漂亮 would be ungrammatical here.

Common mistakes
- Using 好不辣 to mean 'not spicy' – ungrammatical; use 不辣 or 一点也不辣.
- Assuming 好不容易 means 'very easy' – it actually means 'with great difficulty'.
- Applying 好不 freely to adjectives like 大 or 小 – 好不大 does not mean 'very big' and is unnatural.
- Using 好 as a negation – 好 cannot be used with 不 to negate; e.g., 好不干净 does not mean 'very clean' (ungrammatical).
FAQ
- When do I use 好不 vs 好?
- Use 好不 only with the limited list of fixed expressions (e.g., 好不热闹, 好不痛快, 好不伤心) to mean 'very'. For other adjectives, use 好 (e.g., 好漂亮, 好累). Remember that 好不容易 is an exception meaning 'with great difficulty', not 'very easy'.
- Can I use 好不 to mean 'not good' or 'bad'?
- No. The phrase 好不 in isolation does not mean 'not good'; to say 'not good' you use 不好. The 不 in 好不 is part of the fixed intensifier and does not negate the adjective.
- Why does 好不 sometimes mean 'very' and sometimes 'not at all'?
- In modern Mandarin, 好不 + adjective almost always intensifies to 'very' when the adjective itself is positive in tone (e.g., 热闹, 痛快). For adjectives that are already negative (like 自在 in 不自在), 好不 can preserve the negative meaning to mean 'very uncomfortable'. The pattern is idiomatic and must be learned case by case.
- Is 好不 productive? Can I create new expressions like 好不高?
- No, 好不 is not productive. Only a fixed set of adjectives are used in this pattern. 好不高 is ungrammatical and not used. For new contexts, stick with 好 + adjective or 很.
