enough一般有六种用法，分别为enough作名词、代词，形容词，副词，感叹词，固定搭配以及短语，下面易学啦为大家讲价enough的用法：
一、enough可以作名词、代词，意思是"足够;充分"。作代词可以代替可数名词或不可数名词，在句中作主语或宾语。如：
1. Enough has been said on this subject. 关于这一问题说得已经足够多的了。
2. No, thanks. I've had enough. 不，谢谢。我已吃饱了。(enough=enough food)
【注意】当enough后的名词前有冠词、形容词性物主代词、指示代词或其本身就是代词时，要用介词of。如：
We've had enough of your coldness. 我们已经受够了你的冷漠。
二、enough作形容词，意思是"足够的;充分的"，常与for或不定式连用，可以作定语或表语。作定语置于被修饰的名词前后均可，前置时强调enough，后置时强调被修饰词。如：
Five men will be quite enough. 五个人就足够了。
三、enough作副词的意思是 "十分地;充分地;足够地;充足地"，置于被修饰的形容词或副词之后，常与不定式或介词for连用 ，在句子中作状语，表示程度。如：
When they reached the burning building they found that their ladders were not long enough to reach the people who were trapped.
当他们靠近烈火熊熊的大楼时，他们发现梯子不够长，够不着那些被火围困的人。
四、enough作感叹词时意思是"够了;停止;住手;不要再继续了"，用以表达不耐烦或恼怒。如：
You've been practising the violin all afternoon. Enough! 你整个下午都在练小提琴。够了！
五、用在"主语+cannot...+enough"句型中该句型形式上是否定句型，实际上表达的是肯定意义，意思是"再……也不过分；越……越……"。如：
I cannot thank you enough. 我对你感激不尽。(我怎么感谢你都不算过分。)
