Countable vs Uncountable Nouns
Countable nouns are things you can count individually: one apple, two cats, three books. Uncountable nouns cannot be counted separately: water, music, information. Understanding the difference helps you use the correct articles (a/an, the) and verbs (is/are, was/were). This guide shows real examples in different situations.

What to Remember
- Countable nouns name things you can count individually and use the plural form: one apple, two apples.
- Uncountable nouns cannot be counted separately and usually stay singular: water, music, information.
- Use "a/an" with singular countable nouns only: a book, an apple.
- Use "is" with uncountable nouns and singular countables; use "are" with plural countables.
- Some nouns are countable in some languages but uncountable in English: furniture, luggage, advice.
