Quantifiers

• 

We use quantifiers when we want to give someone information about the number of something: how much or how many.

Sometimes we use a quantifierin the place of a determiner:
 

Most children start school at the age of five.
We ate some bread and butter.
We saw lots of birds.

Quantifiers with count and uncount nouns

We can use these quantifiers with both count and uncount nouns:

all	some	more	a lot of	enough
no	any	most	lots of	less

We have lots of time.
Joe has lots of friends.
I can’t go out. I’ve got no money.
There was a lot of food but no drinks.

some and any

We do not normally use the quantifier some in negative and interrogative sentences. We normally use any:

Do you have any children?
Did you see any friends?
We don’t have any children.
I didn’t see any friends.
We saw some lions at the zoo, but we didn’t see any tigers.

but we can use some for offers and requests:

Would you like some tea?
I want some apples, please.

Quantifiers with count nouns

Some quantifiers can be used only with count nouns:

(not) many	each	either	(a) few
several	both	neither	fewer

These more colloquial forms are used only with count nouns:

a couple of

hundreds of

thousands of

I’ll be back in a couple of minutes.
There were hundreds of people at the meeting.

Quantifiers with uncount nouns

Some quantifiers can be used only with uncount nouns:

(not) much

a bit of

a little

Would you like a little wine?
Could I have a bit of butter, please?

These quantifiers are used particularly with abstract nouns such as time, money and trouble:

a great deal of

a good deal of

It will probably cost a great deal of money.
He spent a good deal of time watching television.

both, either and neither

If we are talking about two people or things, we use the quantifiers both, either and neither:

One supermarket	Two supermarkets	More than two supermarkets
The supermarket was closed.	Both the supermarkets were closed.	All the supermarkets were closed.
The supermarket wasn’t open.	Neither of the supermarkets was open.	None of the supermarkets were open.
I don’t think the supermarket was open.	I don’t think either of the supermarkets was open.	I don’t think any of the supermarkets were open.

every and each

We use the quantifiers every and each with singular nouns to mean all:

There was a party in every street. (= There were parties in all the streets.)
Every shop was decorated with flowers. (= All the shops were decorated with flowers.)
Each child was given a prize. (= All the children were given a prize.)
There was a prize in each competition. (= There were prizes in all the competitions.)

We often use every to talk about times like days, weeks and years:

When we were children, we had holidays at our grandmother’s every year.
When we stayed at my grandmother’s house, we went to the beach every day.
We visit our daughter every Christmas.

We do not use a determiner with every and each:

Every shop was decorated with flowers. (NOT The every shop)
Each child was given a prize. (NOT The each child)
