During a grammar lesson, I asked my advanced student to translate “I need more informations.” He said, “What’s wrong with that?” And that’s exactly the moment I realized how tricky uncountable nouns are. The word “information” looks like it could be plural, but English treats it as a singular, non-count mass noun — much like “advice,” “luggage,” or “equipment.”
This guide clarifies which nouns are uncountable, which can shift between countable and uncountable depending on context, and most importantly, which determiners (many, much, few, little, etc.) you must use with each type. These distinctions cause errors in nearly every student’s early writing, but they’re learnable once you see the patterns.
Key Takeaways
- Uncountable (mass) nouns have no plural form — information, advice, furniture, luggage, equipment.
- Use much, little, less for uncountable; use many, few, fewer for countable — “much information” (not “many”), “many books” (not “much”).
- Some nouns shift between countable and uncountable — “glass” (uncountable material) vs. “a glass” (countable drinking vessel); “coffee” (uncountable drink) vs. “two coffees” (two cups).
- Plural-only nouns like police, cattle, clothes need careful handling — always plural verb, no indefinite article “a/an”.
- When in doubt, count in your context — If you can say “one X, two X’s,” it’s probably countable. If not, it’s likely non-count.
What Are Uncountable Nouns?
Uncountable nouns (also called mass nouns or non-count nouns) refer to things we conceptualize as substances, materials, abstract qualities, or collections without distinct boundaries or separate units. They have no plural form and are treated as singular grammatically.
Example 1: “Water” — you cannot say “three waters” in standard English (though you can say “three glasses of water”).
Example 2: “Furniture” — always singular. “The furniture is new” (never “furnitures are”).
Example 3: “Information” — you say “some information” or “a piece of information,” never “informations.”
Common Categories of Uncountable Nouns
1. Materials and Substances
- Metals: gold, silver, copper, iron, aluminum
- Liquids: water, milk, oil, honey, juice, alcohol, blood
- Grains and cereals: rice, wheat, barley, oats, corn
- Powders and granular substances: sugar, salt, pepper, flour, sand, dust, chalk
- Other materials: glass, paper, plastic, wood, cloth, leather
Example 1: “I need to buy rice for dinner.” (Not “three rices”)
Example 2: “We use steel in construction.” (Not “steels”)
Example 3: “The salt has spilled everywhere.” (Not “salts are spilled”)
2. Abstract Nouns (Qualities, Concepts, States)
- Qualities and conditions: health, knowledge, beauty, courage, honesty, strength
- Emotions and states: love, hate, anger, joy, sadness, confusion, anxiety
- Concepts and ideas: freedom, justice, democracy, education, science, music, art
- Uncountable information types: information, advice, news, data, evidence, research, knowledge
Example 1: “She has a lot of knowledge about biology.” (Not “knowledges”)
Example 2: “News is coming from many sources.” (Not “newses are” — and “news” takes singular verb)
Example 3: “The advice she gave was helpful.” (Not “advices were”)
The information/advice trap: In English, we never pluralize “information” or “advice” even in meaning-equivalent contexts where other languages do. You must say “several pieces of advice” or “several items of information,” not “advices” or “informations.”
3. Collections and Groups (When Treated as Mass)
- Furniture, luggage, baggage, equipment, machinery — these are collections of items treated as one uncountable mass
- Traffic, transport (British), accommodation — treated as abstract concepts or collections
Example 1: “The furniture in my apartment is minimal.” (Never “furnitures”)
Example 2: “Check your luggage before boarding.” (Never “luggages”)
4. School Subjects and Languages
- Languages: English, Spanish, Mandarin, Arabic (no plurals)
- School subjects (when referring to the discipline): mathematics (maths), physics, chemistry, history, geography
Example 1: “She is studying English and mathematics.” (Not “Englishes” or “mathematics are”)
Example 2: “Maths is challenging for many students.” (Singular verb, even with -s ending)
Nouns That Can Be Countable OR Uncountable
This is where things get tricky. Some nouns can function as either countable or uncountable depending on meaning and context:
| Noun | Uncountable (Mass) Use | Countable (Individual) Use |
|---|---|---|
| Paper | I need more paper for my printer. (the substance) | She published three papers in scientific journals. (individual documents) |
| Glass | The building is made of glass. (the material) | Please bring me a glass of water. (a drinking vessel) |
| Coffee | I drink a lot of coffee. (the beverage) | Let’s have two coffees at the café. (two cups of coffee) |
| Hair | She has long hair. (the substance/collection) | There is a hair on your shirt. (a single strand — usually “strand of hair”) |
| Experience | She has a lot of experience in teaching. (accumulated knowledge) | That was a wonderful experience. (a specific event or moment) |
| Time | Time is precious. (the concept) | We had a great time at the party. (a period or instance) |
Key insight: When you can think of something as a countable unit or instance, it becomes countable. When you think of it as a substance or abstract mass, it stays uncountable.
The Determiner Rule: Which Words Go With Which Nouns?
This is the most practical rule for avoiding errors. English has different determiners for countable and uncountable nouns:
Determiners for Countable Nouns (Plural)
- Many: “I have many friends.” (Not “much friends”)
- Few / A few: “Few people attended.” (Few = not many; a few = some)
- Several: “Several students were absent.”
- A number of: “A number of factors contributed.”
Determiners for Uncountable Nouns
- Much: “I don’t have much time.” (Not “many time”)
- Little / A little: “Little progress was made.” (Little = not much; a little = some)
- Less: “The company generated less revenue.” (Less is for uncountable; fewer is for countable)
- A bit of: “Add a bit of salt to the water.”
- An amount of: “A large amount of equipment was damaged.”
Determiners That Work With BOTH
- Some: “some books” (countable) / “some water” (uncountable)
- A lot of / Lots of: “a lot of apples” / “a lot of patience”
- No / Not any: “no time” / “no apples”
- Hardly any: “hardly any opportunities” / “hardly any progress”
The much vs. many rule: In the context of writing, this is the #1 determiner error. “Much” is for uncountable; “many” is for countable. “Much information” (correct). “Many documents” (correct). When you see “fewer vs. less,” the same logic applies: “fewer apples” (countable), “less sugar” (uncountable).
Nouns Ending in -S That Are Uncountable
Some nouns ending in -s are uncountable and take singular verbs. This is another common trap:
| Noun | Meaning | Verb Agreement | Example |
|---|---|---|---|
| News | Information about recent events | Singular | “The news is good.” (Never “news are”) |
| Maths / Mathematics | The discipline of math | Singular | “Mathematics is challenging.” (Usually singular, though plural possible in British English in informal contexts) |
| Physics / Chemistry | Academic disciplines | Singular | “Physics is fascinating.” |
| Measles / Mumps | Diseases | Singular | “Measles is contagious.” |
| Billiards / Darts | Games | Singular | “Darts is played in pubs.” (Though plural possible: “Darts are played”) |
Always-Plural Nouns (Plural Only)
Some nouns are always plural and should be treated as plural, even though they refer to a single object:
- Clothing: trousers, jeans, shorts, pants, tights, underwear
- Tools/Objects: scissors, tweezers, pliers, binoculars, glasses (spectacles)
- Other: goods, groceries, remains, surroundings, customs (at border)
To count these items, use “a pair of”: “a pair of scissors,” “three pairs of jeans.”
Example 1: “My trousers are on the chair.” (Always plural, never “trouser is”)
Example 2: “I need a new pair of glasses.” (Use “pair” to count them)
Common Mistakes with Uncountable Nouns
✗ Incorrect: I told these news to my father.
✓ Correct: I told this news to my father.
Why: “News” is uncountable. Use “this” not “these”; use “is” not “are.”
✗ Incorrect: The teacher gave us many advices about grammar.
✓ Correct: The teacher gave us much advice about grammar.
Why: “Advice” is uncountable. Use “much” not “many”; do not pluralize to “advices.”
✗ Incorrect: We need more informations and furnitures for the office.
✓ Correct: We need more information and furniture for the office.
Why: Both “information” and “furniture” are uncountable mass nouns. Never pluralize them.
✗ Incorrect: The equipment are broken.
✓ Correct: The equipment is broken.
Why: “Equipment” is uncountable and takes a singular verb, though it refers to multiple items.
✗ Incorrect: She has fewer time than her brother.
✓ Correct: She has less time than her brother.
Why: “Time” is uncountable. Use “less” not “fewer.”
Student: Why can’t I say “three informations”? There are three pieces of information.
Teacher: Good question. English treats “information” as an uncountable mass, like “water” or “rice.” You don’t count water molecules individually; you just say “water.” Same with information — it’s one abstract substance. To count it, you must use a measure word: “three pieces of information,” “three items of news,” “three pieces of advice.”

Frequently Asked Questions
How do I know if a noun is countable or uncountable?
Ask yourself: Can I count individual units of it? “One apple, two apples” (countable). “Water” — I can’t say “one water, two waters” without a measure word like “glass” or “bottle” (uncountable). When in doubt, try using “a/an” with the singular and see if it sounds natural. “A book” (yes, countable). “A furniture” (no, uncountable).
Can I use a/an with uncountable nouns?
No. You cannot say “a information” or “an advice.” However, you can use “a piece of information” or “a bit of advice.” Indefinite articles require countable nouns in singular form.
Is “data” singular or plural?
Traditionally, “data” is the plural of “datum” (singular). However, in modern English, especially in casual contexts, “data” is increasingly treated as uncountable/singular: “The data is clear.” Formally, “data are” is still correct, but “data is” is now widely accepted.
Why does “news” end in -s but take a singular verb?
“News” is historically derived from the plural of “new” (meaning “new things”), but in modern English it’s treated as an uncountable singular noun. Similarly, “physics” and “mathematics” look plural but function as singular uncountable nouns. This is a quirk of English history and word borrowing.
Can I pluralize abstract nouns like “happiness” or “freedom”?
Technically yes, but it’s rare. You can say “the various happinesses of life” in literary or formal contexts, but in everyday English, these remain non-count. “Happiness is important” (standard). “Happinesses are important” (poetic or unusual).
What’s the difference between “fewer” and “less”?
“Fewer” is for countable nouns: “fewer apples,” “fewer mistakes.” “Less” is for uncountable nouns: “less time,” “less money.” Common error: “less people” (incorrect) should be “fewer people” (people is countable in this context).
