We use quantifiers such as much, many, little, few, a lot and plenty when we want to give someone information about the number of something.
Much can be used ONLY with noncount nouns:
Examples:
How much money do you have?
There isn’t much coffee left.
We can use a lot of or lots of with both count and non-count nouns:
Examples:
We have lots of time.
Jerry has lots of friends.
There was a lot of food.
Plenty of is a colloquial form which can also be used with both count and non-count nouns:
Examples:
We have plenty of time.
Joe has plenty of friends.
There was plenty of food.
Many and a few can be used ONLY with count nouns:
Examples:
She asked too many questions.
The crowd was silent for a few minutes after the play ended.
Remember:
We put a noun directly after a quantifier when we talk about members of a group in general.
Examples:
Few snakes are dangerous.
You can learn many things from books.
But if we are talking about members of a particular group, we also use “of the”.
Examples:
Few of the snakes in this zoo are dangerous.
Many of the kids played in the park.
