    more dramatic and literary; suggests severe disturbance

反義詞
  • sane

    mentally healthy and of sound mind

    thinking clearly and rationally

文法句型

be crazy

go crazy

act crazy

用法筆記

This sense can be offensive when used to describe someone with an actual mental health condition. In modern usage it appears mostly in historical contexts, in quoted speech, or as an informal exaggeration ('I feel like I am going crazy with all this work'). The clinical terms 'mentally ill' or 'having a mental health condition' are preferred in serious contexts.

常見錯誤

She is crazy and needs to see a doctor.' (offensive).
She has a mental health condition and needs professional support.
💡'Crazy' in a medical context sounds dismissive and insulting.

同義詞
  • annoyed

    milder and more general; does not require a fixed phrase pattern

    much stronger; suggests extreme anger

  • irritated

反義詞
  • calm

    not angry or upset

    able to stay calm in a frustrating situation

文法句型

drive someone crazy

go crazy

make someone crazy

用法筆記

This sense appears almost exclusively in the fixed patterns 'drive someone crazy', 'go crazy', or 'make someone crazy'. The adjective by itself ('I am crazy') does not convey anger — that reading only works inside these constructions.

常見錯誤

I am crazy about the noise from the street.
The noise from the street is driving me crazy.
💡'Crazy about' means enthusiastic, not angry. Use 'drive someone crazy' for annoyance.

同義詞
  • enthusiastic

  • passionate

    similar intensity but suggests emotional depth rather than obsessive interest

  • obsessed

    stronger and more negative; suggests the interest has become unhealthy

  • mad

    British equivalent; 'mad about football' means the same as 'crazy about football'

反義詞

文法句型

crazy about + noun/gerund

crazy for + noun

go crazy for/over + noun

用法筆記

Commonly followed by 'about' or 'for' to specify the object of enthusiasm. 'Crazy about' is more frequent in British English; 'crazy for' is more frequent in American English. The structure 'go crazy for/over' describes the moment of becoming enthusiastic.

常見錯誤

I am crazy about to play tennis.
I am crazy about playing tennis.
💡'Crazy about' must be followed by a noun or a gerund (verb + -ing), not an infinitive.
