Countable and Uncountable Nouns: Rules and Examples
"Two informations" and "much apples" are both grammatically wrong for the same reason: mixing up countable and uncountable nouns. This distinction affects which articles, quantifiers, and verb forms you can use — making it one of the most practical grammar points to get right early.
What Are Countable Nouns?
Countable nouns can be counted individually and have both singular and plural forms.
one apple, two apples, three books, several ideas
What Are Uncountable Nouns?
Uncountable nouns refer to things that can't be separated into individual units — usually substances, abstract concepts, or collective categories. They have no plural form.
water, rice, information, advice, furniture, money, traffic
You never say "two waters" (unless ordering, informally, meaning two bottles/glasses) or "informations."
Common Uncountable Nouns That Confuse Learners
- information (not "informations")
- advice (not "advices")
- furniture (not "furnitures")
- news (not "news" as plural — "The news is good," not "are")
- luggage/baggage
- equipment
- homework
Quantifiers for Countable vs Uncountable Nouns
| Countable | Uncountable |
|---|---|
| many, a few, several | much, a little, a bit of |
| a number of | a great deal of |
| these, those | this, that |
"I have many books" vs "I have much water" "There are a few apples left" vs "There is a little rice left"
Food Vocabulary: A Perfect Example
Food is one of the clearest places to see this rule in action: individual fruits and vegetables are usually countable (an apple, two carrots), while staples like rice, bread, and pasta are uncountable (some rice, a loaf of bread). See our full food vocabulary guide for more examples.
Nouns That Can Be Both
Some nouns change meaning depending on whether they're countable or uncountable:
- "I had an interesting experience." (countable — a specific event)
- "She has a lot of experience." (uncountable — general knowledge/skill)
- "Can I get a coffee?" (countable — a cup of coffee)
- "I don't drink coffee." (uncountable — the substance in general)
Common Mistakes
- Using "much" with countable nouns ("much books" — incorrect; should be "many books")
- Adding "-s" to uncountable nouns ("informations," "advices")
- Using "a" or "an" directly with uncountable nouns without a counting phrase ("a water" instead of "a glass of water")

FAQ
Is "advice" countable or uncountable? Uncountable — you say "a piece of advice" or "some advice," never "an advice" or "advices."
Why do some nouns change meaning between countable and uncountable forms? Because the countable form usually refers to a specific instance or type, while the uncountable form refers to the general substance or concept.
What's the fastest way to memorize which nouns are uncountable? Learn them in context through reading and example sentences rather than as an isolated list — categories like food and abstract concepts (information, advice, knowledge) are the most common uncountable groups.
