Countable nouns
- Can be counted: one apple, two apples.
- Have singular and plural forms.
Uncountable nouns
- Cannot be counted: water, sugar, rice, money.
- Use 'some' or 'a lot of', not 'a/an' or numbers.
Key idea
Countable nouns can be counted and made plural (apples); uncountable nouns cannot (water, sugar).
Remember
Use 'much' with uncountable and 'many' with countable nouns.
