ENOUGH is word that can qualify an adverb or an adjective. It can also go together with a noun or sometimes act as a pronoun.
1. ENOUGH with adjectives and adverbs
Position in a sentence: after an adjective or an adverb
- Your work isn’t good enough for our company.
- He finished the project quickly enough, and we could move on to the next one.
2. ENOUGH with nouns
Position in a sentence: before a noun
- There aren’t enough tomatoes in the fridge.
- Do you have enough money to pay for gas?
3. ENOUGH without a noun
We can also use ENOUGH without a noun:
- That’s enough! Turn of the TV!
- Enough is enough! (we use this phrase to express that we are really frustrated with something, or tired)
4. ENOUGH OF
We use ENOUGH OF only when there is a determiner (this/that, an article, his/her/my, etc.)
- I haven’t done enough of the research to be able to tell the results.
- He hasn’t spent enough of his money to ask for more.
NOTE: When we use ENOUGH with an adjective or a noun two sentence positions are possible, but the meaning will change:
- We don’t have enough big sweaters for tomorrow’s field trip. (we have some big sweaters, but we need more)
- We don’t have big enough sweaters for tomorrow’s field trip. (the sweaters we have are too small, we need bigger sweaters.)
I hope this is clear now 🙂
