Articles and quantifiers depend on two questions: is the noun countable, and does the reader already know which one you mean? Answer those two questions and the choice is no longer a guess.
This lesson is part of grammar repair. Number also decides verb forms, so review subject-verb agreement if you need it.
How do you choose an article?
Use three questions in order.
- Is the noun countable and singular? If yes, it needs an article: a, an or the.
- Does the reader know exactly which one? If yes, use the. If it is new or one of many, use a or an.
- Is the noun plural or uncountable and general? Then use no article.
This gives “I saw a cat” (new), “The cat was asleep” (known) and “Cats sleep a lot” (plural, general).
Worked example: a paragraph repaired
Here is an original paragraph with slips.
“My brother bought laptop last week. Laptop has much problems with battery. He asked shop assistant for advices, but she gave him an information about warranty only.”
Repair it in steps. “Laptop” is singular and new, so write “a laptop”. The second mention is known, so write “The laptop”.
“Much problems” fails because “problems” is plural and countable, so “many problems”. “Shop assistant” is one specific person, so “the shop assistant”. “Advices” is uncountable, so “advice”.
“An information” also fails because “information” is uncountable, so write “some information”.
The corrected version: “My brother bought a laptop last week. The laptop has many problems with the battery. He asked the shop assistant for advice, but she gave him some information about the warranty only.”
Which quantifier goes with which noun?
| Noun type | Example | Quantifiers that fit |
|---|---|---|
| Countable plural | books, students | many, few, a few, a lot of |
| Uncountable | water, advice, homework | much, little, a little |
| Both | time, room | some, a lot of, plenty of |
The mistake: adding -s to an uncountable noun
Students often write “informations”, “furnitures” or “homeworks” because these things feel like groups. English treats them as uncountable, so the noun stays singular and takes “some” or “a piece of”.
| Wrong | Right |
|---|---|
| I have many homeworks. | I have a lot of homework. |
| She gave me an advice. | She gave me some advice. |
| The furnitures are old. | The furniture is old. |
The verb changes too: “furniture is”, because the noun is singular.
Check yourself
Correct the sentences. (1) “I need informations about scholarship.” (2) “There is little students in the hall.” (3) “She is best player in team.”
Answer
(1) “I need some information about scholarships.” or “…about a scholarship.” “Information” is uncountable, and “scholarship” needs an article or a plural form.
(2) “There are few students in the hall.” “Students” is countable and plural, so “few” replaces “little”.
(3) “She is the best player in the team.” A superlative needs “the”, and “team” is a known, specific team.
