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 quantifiers (e.g. some, a few,a lot of, many) with plural countable nouns:
There are some birds in my garden.
3. Use a plural noun to make 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:
I eat one bread almost every day.
2. You can use quantifiers (e.g. some, a little, a lot of, much) with uncountable nouns:
I had some coffee this morning.
3. Use uncountable nouns to make generalisations:
I like wine.
4. 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 chicken. (= the food, you only usually eat a part of it 🍗)
I ate some cakes. (= wow - three whole cakes! 🎂🎂🎂)
I ate some cake. (= a piece of cake 🍰)
I want an ice cream. (= one whole ice cream, you lick it 😛 🍦)
