Countable and Uncountable Nouns in English: Rules, Tricky Words and Much, Many, A Lot Of

Countable nouns are things you can count one by one (a book, two books), so they have a singular and a plural form. Uncountable nouns are things English treats as a mass or an idea (water, information, advice), so they have no plural and cannot take a or an. Use many with plural countable nouns, much with uncountable nouns, and a lot of with both. This guide explains the rules with examples, lists the tricky words that are uncountable in English but countable in many other languages, shows how to count uncountable things (a piece of advice, two cups of coffee), and ends with a practice exercise and answers.

What countable and uncountable nouns are

A countable noun (also called a count noun) refers to separate items. You can use a number with it, and it has a plural: an apple, three apples; a job, two jobs; a problem, many problems.

An uncountable noun (also called a mass noun or non-count noun) refers to a substance, a material, a mass, or an abstract idea that English does not divide into separate units: water, rice, money, music, happiness, homework. It has no plural form, and it takes a singular verb: The information is correct (not informations are).

The important word is "English". Whether a noun is countable is partly a grammar choice, not only a fact about the world. Rice is made of separate grains, but in English rice is uncountable. In French, informations can be plural; in English, information cannot. That is why learners make mistakes even when they understand the idea.

The Cambridge Grammar of English and good learner dictionaries mark every noun as [C] countable or [U] uncountable. When you are not sure, check the dictionary entry.

The grammar differences at a glance

Feature	Countable nouns	Uncountable nouns
Plural form	Yes: a chair, chairs	No: furniture (never furnitures)
a / an	Yes, with singular: a chair	No: a furniture is wrong
Numbers	Yes: three chairs	Only with a unit: three pieces of furniture
Verb	Singular or plural: The chair is / The chairs are	Always singular: The furniture is
"How ...?"	How many chairs?	How much furniture?
Small quantity	a few, few, fewer	a little, little, less
Both types	some, any, a lot of, lots of, plenty of, no, enough, more, most

A singular countable noun almost always needs a word in front of it, such as a, the, my, this or every. You cannot say I bought car; you must say I bought a car or I bought the car. Uncountable nouns and plural nouns can stand alone when you talk in general: Money doesn't buy happiness. Cars are expensive. Our guide to a, an and the explains this in detail.

How to use much, many and a lot of

These three are the most useful quantity words, and the rule is simple once you know whether the noun is countable.

Word	Used with	Most common in	Examples
many	Plural countable nouns	Questions and negatives; also formal positive sentences	How many people came? There aren't many tickets left. Many students work part-time.
much	Uncountable nouns	Questions and negatives	How much time do we have? I don't have much money.
a lot of / lots of	Both	Positive sentences, everyday speech; also questions and negatives	We have a lot of work. She has lots of friends. Did you spend a lot of money?

Based on Cambridge Dictionary, Much, many, a lot of, lots of: quantifiers, which notes that lots of is more informal than a lot of.

Why "I have much money" sounds strange

Grammatically, much works with uncountable nouns, but in positive statements in everyday English, speakers normally use a lot of:

• Natural: I have a lot of money.
• Sounds formal or unnatural in speech: I have much money.
• Natural: I don't have much money. / Do you have much money?

Much is normal in positive sentences after too, so, as and very: There's too much sugar in this. I've learned so much. Many is more flexible: Many people think... is common in both speech and writing.

Leaving out the noun

When the noun is obvious, drop it, and drop of after a lot: "How many tickets do you need?" "Not many." "Did it cost much?" "Yes, a lot."

Common tricky words: uncountable in English

These nouns are uncountable in English but often countable in learners' first languages. They cause the most mistakes in writing and in exams.

Uncountable noun	Wrong	Right	To count it
advice	She gave me an advice.	She gave me some advice.	a piece of advice, a tip, a suggestion
information	Two informations	Some information	a piece of information, a detail, a fact
news	The news are good.	The news is good.	a piece of news, a news story
furniture	New furnitures	New furniture	a piece of furniture, a chair, a table
equipment	Equipments	Equipment	a piece of equipment, a tool, a machine
luggage / baggage	Three luggages	Three bags / three pieces of luggage	a suitcase, a bag, an item of luggage
homework	Many homeworks	A lot of homework	an exercise, an assignment, a task
research	Researches show...	Research shows...	a study, a research project
knowledge	Knowledges	Knowledge	(often: a good knowledge of; see below)
progress	A progress	Progress	a step forward, an improvement
work	I have a work.	I have a job. / I have work.	a job, a task, a project
traffic	Many traffics	A lot of traffic	a car, a vehicle, a traffic jam
accommodation (British English)	Accommodations	Accommodation	a room, a flat, a place to stay
software	Softwares	Software	a program, an app, a software package
vocabulary	Vocabularies	Vocabulary	a word, a phrase, an expression

Cambridge Dictionary has separate usage notes on several of these, for example advice, information and research. In American English, accommodations (plural) is common.

Many of these appear in our list of 20 common English grammar mistakes, because they are among the errors teachers correct most often.

How to count uncountable things

To count an uncountable noun, put a countable "unit" word in front of it with of. Learning these as fixed phrases (chunks) is the fastest way to use them naturally; see our guide to learning vocabulary in chunks.

Unit	Used with	Examples
a piece of	Many general and abstract nouns	a piece of advice, a piece of information, a piece of furniture, a piece of cake
a cup / glass / bottle of	Drinks and liquids	a cup of tea, a glass of water, a bottle of oil
a slice of	Food that you cut	a slice of bread, a slice of pizza
a bag / packet / box of	Food and materials	a bag of rice, a packet of pasta, a box of cereal
a kilo / litre / metre of	Measures	a kilo of flour, two litres of milk
an item of / an article of	Formal: clothing, news, luggage	an item of clothing, an article of clothing
a sheet of	Paper and flat materials	a sheet of paper, a sheet of glass
a bar of	Solid blocks	a bar of chocolate, a bar of soap
a drop of / a bit of	Small amounts (a bit of is informal)	a drop of milk, a bit of help

The unit word becomes plural, not the uncountable noun: two pieces of advice (not two piece of advices), three cups of coffee.

Nouns that can be both countable and uncountable

Many nouns change meaning depending on whether they are countable. This is normal, not an exception to memorise word by word.

Noun	Uncountable meaning	Countable meaning
coffee / tea / beer	The drink in general: I don't drink coffee.	A cup or glass of it: Two coffees, please.
chicken / fish / lamb	The meat: We had chicken for dinner.	The animal: She keeps three chickens.
time	Time in general: I don't have much time.	Occasions: I've been there three times.
experience	Knowledge from doing something: She has a lot of experience.	Events: It was an amazing experience.
paper	The material: a sheet of paper	A newspaper or document: I bought a paper. She wrote a paper on AI.
room	Space: Is there room for one more?	Part of a building: The flat has three rooms.
hair	All the hair on your head: She has long hair.	Single hairs: There's a hair in my soup!
business	Commercial activity: Business is good.	A company: He runs two businesses.
light	Brightness: There isn't enough light.	A lamp: Turn off the lights.

Some abstract uncountable nouns take a when an adjective or phrase describes a particular kind: a good education, a deep knowledge of history, a strong interest in art. You still cannot make them plural in normal use.

A few, a little, fewer and less

• a few + plural countable: I have a few questions. (some, a small number; positive)
• few + plural countable: Few people came. (not many; sounds negative)
• a little + uncountable: I speak a little Spanish. (some; positive)
• little + uncountable: There is little hope. (not much; negative, formal)
• fewer + plural countable: fewer cars, fewer mistakes
• less + uncountable: less traffic, less time

In everyday speech, many native speakers say less people, but in exams and formal writing, use fewer with countable nouns.

The most common learner mistakes

1. Adding -s to an uncountable noun: advices, informations, furnitures, homeworks. Fix: use some or a unit word.
2. Using a / an with an uncountable noun: a good news, an advice. Fix: some good news, a piece of advice.
3. Plural verb with an uncountable noun: The news are..., The money are.... Fix: singular verb.
4. much with plural nouns: How much people...? Fix: How many people?
5. many with uncountable nouns: many traffic, many time. Fix: a lot of traffic, much time.

How to practise countable and uncountable nouns

• Learn nouns with a partner word. Do not learn advice; learn some advice / a piece of advice. Do not learn chair; learn a chair.
• Check the dictionary label. Look for [C] or [U] every time you meet a new noun you will use.
• Proofread for the top ten. Before you submit an essay or email, search it for advice, information, news, research, equipment, furniture, homework, work, knowledge, progress.
• Read a lot. You absorb patterns like a lot of traffic by meeting them many times; see learning vocabulary through reading.
• Get feedback. A teacher will catch the mistakes you cannot see yourself. Our courses include writing correction, and our free lessons and free grammar PDF give extra practice.

What this article cannot tell you

• Every noun. English has thousands of nouns, and some are countable in one meaning and uncountable in another. Use a learner dictionary for individual words.
• Every variety of English. Usage differs between British and American English in a few cases, such as accommodation. See British vs American English.
• Specialist uses. In science, business and cooking, uncountable nouns are sometimes used in the plural to mean "types of" (French wines, new materials, local cheeses). Check a dictionary before you use these in exams.
• Your personal mistakes. Only feedback on your own writing and speaking shows which patterns you need to work on.
