• Before a noun, use too much (uncountable nouns) or many (countable nouns).

Enough




Use: Enough means you have what you need.

• But write it after an adjective or verb.

Such

Use: Such also means very. Such is used before an adjective and noun.
They are such nice children.  

Form:

• A / an, if necessary, go after such, not before.

Common mistakes
1) Some students use too with a positive meaning. But use so or very here
It’s too hot! I love the summer! => It’s so hot! I love the summer!
2) Some students write enough in the wrong place.
Do we have sugar enough? => Do we have enough sugar?
3) Some students use so / such…that incorrectly.
It was so hot that the sun was shining.
This sentence is not correct because ‘the sun was shining’ is not a direct result of ‘It was so hot’. The hot day did not cause the sun to shine
