Countable and uncountable nouns
Countable nouns (book, idea, country) can be counted and have plural forms; uncountable nouns (information, advice, furniture, news) have no plural and take singular verbs. Many uncountable nouns describe things that feel plural, which is why learners often add -s to them, but forms like 'informations' or 'an advice' are always wrong.
Which one do I need?
Countable or uncountable?
Every answer at a glance
a / an + singular noun
A singular countable noun cannot stand alone: put a, an, one, the or a possessive in front of it.
Each student must choose a topic for the final project.
plural + many / few / several
For more than one, add -s and use plural quantity words: many, a few, several, a number of. The verb is plural too.
Several countries have banned plastic bags in recent years.
a piece of / an item of
Count the container, not the noun: a piece of advice, two items of luggage, a slice of bread. The container takes the -s.
We were allowed only one piece of hand luggage each.
some / much / a lot of, no -s
Uncountable nouns have no plural, never take a or an, and take a singular verb: some information, much furniture, the news is.
The equipment in the new lab is excellent, but we need more furniture.
countable: an experience, a hair
Some nouns are countable when they mean one event, strand or document: an experience, a hair, a paper, three times.
Volunteering at the festival was an experience I will never forget.
uncountable: experience, hair
The same nouns are uncountable for the general thing: experience (skill), hair, paper (the material), time. No a, no -s.
The job requires experience in marketing and good computer skills.
How to use countable and uncountable nouns
What makes a noun countable?
A countable noun refers to something you can count as separate, individual units: one city, two cities, three ideas. Countable nouns have a singular and a plural form, can follow a/an or a number, and pair with quantifiers like many, few and several.
Most nouns in English are countable, and they behave predictably: add -s or -es for the plural, use a/an for one, and switch to a plural quantifier when there's more than one.
- She has visited seven countries this year.
- I need a new idea for my presentation.
- There are three empty chairs at the back of the room.
What makes a noun uncountable?
An uncountable noun refers to something treated as a whole, undivided mass rather than separate units: a substance, a quality, or a general category. Uncountable nouns have no plural form, never follow a/an, and always take a singular verb, even when the concept feels 'more than one'.
Common groups include liquids and substances (water, rice, sugar), abstract qualities (honesty, patience, knowledge), weather (rain, sunshine), and broad categories that stand in for many individual items (furniture, luggage, equipment, traffic, jewellery).
- Patience is essential when you're learning a new language.
- There was heavy traffic on the way to the airport this morning.
- The rice was still warm when we sat down to eat.
Classic 'trap' nouns: information, advice, furniture, news, research
A specific set of nouns cause the most persistent uncountable-noun errors, because they describe things that feel like they should be plural or countable but grammatically behave as a single mass. Information, advice, furniture, news, research, luggage and equipment are the repeat offenders in learner writing and speech.
Each of these has a natural 'container' word for talking about one unit (a piece of information, a piece of advice, an item of furniture) and each takes a singular verb, however plural its meaning feels: the news is, not the news are.
| Uncountable noun | Wrong | Right |
|---|---|---|
| information | informations, an information | some information, a piece of information |
| advice | an advice, advices | some advice, a piece of advice |
| furniture | a furniture, furnitures | a piece of furniture, some furniture |
| news | a news, the news are | a piece of news, the news is |
| research | a research, researches | some research, a piece of research |
| luggage | a luggage, luggages | a piece of luggage, some luggage |
- Could you give me some information about the visa application process?
- The research is still at an early stage.singular verb, despite 'research' sounding like an ongoing set of activities
How do you count an uncountable noun?
Since uncountable nouns can't take a/an or a plural -s, English measures them instead with quantifier phrases: a piece of, a bit of, an item of, a slice of, a bowl of, a lot of, some. These phrases (not the noun itself) become countable, and it's the phrase that takes the plural: two pieces of advice, three items of luggage.
General quantity words like some, a lot of, a great deal of and little work directly with uncountable nouns, without any container word needed.
- He gave me three separate pieces of advice before the interview.
- We don't have much furniture yet; we only moved in last week.
- There's a lot of information on the university's website.
Nouns that switch between countable and uncountable
Some nouns are uncountable in a general sense and countable when they refer to a specific type or instance. Hair is uncountable when it means everything on your head ('She has curly hair'), but countable when it means a single strand ('There's a hair in my soup'). Paper is uncountable as a material and countable as a document.
Watch for this shift especially with experience (uncountable = general expertise; countable = a specific event) and time (uncountable = the general concept; countable = occasions, as in 'three times'). The article and the plural -s are your clue to which meaning is intended.
- Living abroad gave her a lot of experience she couldn't have gained at home.uncountable → general expertise
- Moving to a new country alone was one of the hardest experiences of my life.countable → a specific event
- I've already told you three times not to leave the door unlocked.countable 'times' = occasions
