What this grammar point covers

Countable nouns are things you can count (one apple, two apples). Uncountable nouns are things you cannot count (water, rice).

When to use it

Use this grammar when you want to talk about the quantity of things in English. Countable nouns are for separate items you can count. Uncountable nouns are for things you cannot count easily, like liquids or materials.

Key forms

a/an + countable noun (a book, an apple)
some + uncountable noun (some water)
many + countable noun (many books)
much + uncountable noun (much sugar)
How many...? (How many chairs?)
How much...? (How much milk?)

Examples

There is some milk in the glass.

How many books do you have?

How much water do you need?

She eats rice every day.

Tips

Do not use 'a' or 'an' with uncountable nouns. Say 'some water', not 'a water'.
Use 'many' with countable nouns and 'much' with uncountable nouns.
Some nouns can be countable or uncountable with different meanings (e.g., 'chicken' as an animal is countable, as food is uncountable).

Exceptions and edge cases

Some nouns can be both countable and uncountable, but the meaning changes (e.g., 'paper' as material is uncountable, but 'a paper' means a newspaper or an essay).
