Countable and uncountable nouns
A countable noun can be counted. You can have one, two or more of them, and they have a plural (usually with -s at the end). Uncountable nouns can't be counted and there is no plural.
She's got four cats. ('cat' is countable - you can have one or more)
Her cats drink milk. ('milk' is uncountable - we don't usually say 'milks')
Things to remember with countable nouns
1. Use a/an or numbers to count nouns:
I have four cats.
I bought a book.
2. Use some quantifiers (e.g. some or a lot of) with plural countable nouns.
There are some birds in my garden.
3. Use the plural when making generalisations:
I like presents.
4. Singular countable nouns = it, plural countable nouns = they:
My cat is cute → It is cute.
Cats are cute → They are cute.
Things to remember with uncountable nouns
1. Don't use a/an or numbers. You can use some quantifiers (e.g. some or a lot of) with uncountable nouns.
I had some coffee this morning.
2. Use uncountable nouns to make generalisations
I like wine.
2. Uncountable nouns = it, so uncountable nouns always use the third person verb form (e.g. is, has, likes).
Coffee is delicious → It is delicious.
Countable or uncountable?
Some nouns can be countable or uncountable, depending on the meaning.
I like chickens. (= the whole animal, you can count these)
I like chicken. (= the food, you only usually eat a part of it)
I ate some chocolates. (= some little chocolates from a box of many)
I ate some chocolate (= part of a bar of chocolate).
I want an ice cream (= one whole ice cream usually in a cone, you lick it 🍦)
I want some ice cream (= some from a tub, eat it with a spoon)
