Introduction
Have you ever stood in a supermarket checkout lane and noticed the sign that says “10 items or less”? If you have, you may have felt a small, nagging doubt: should it be “fewer” instead? You are not alone. This is one of the most common grammar confusions in English, and even native speakers get it wrong. In this guide, we will clear up the difference between fewer and less once and for all. By the end, you will know exactly when to use each word, and you will never be tricked by a supermarket sign again.
What Is the Difference Between “Fewer” and “Less”?
At its simplest, the rule is this: fewer is used with countable nouns (things you can count individually, like apples, chairs, or people), and less is used with uncountable nouns (things you measure in bulk or as a whole, like water, time, or money). Think of it this way: if you can put a number in front of the noun (e.g., three apples, two chairs), you need fewer. If you cannot easily count it (e.g., less water, less patience), you need less.
Rules for Using “Fewer” and “Less”
- Use “fewer” with plural countable nouns. Example: I have fewer books than my brother. (Books can be counted: one book, two books.)
- Use “less” with uncountable nouns. Example: I have less homework today. (Homework is not counted individually; it is a mass concept.)
- Use “less” with singular countable nouns that refer to a quantity or amount. Example: I need less sugar in my coffee. (Sugar is uncountable here, but even if we say “a sugar cube,” we treat it as an amount.)
- Use “less” with numbers, measurements, and time when they are seen as a whole. Example: It costs less than ten dollars. (Dollars are countable, but “less than” is a fixed phrase for amounts.)
- Use “fewer” when the noun is clearly countable and plural. Example: There are fewer students in class today. (Students are countable.)
How to Use “Fewer” and “Less” Step by Step
Step 1: Identify the Noun
First, look at the noun that follows the word. Is it countable or uncountable? Ask yourself: Can I put a number in front of it? For example, “cars” is countable (two cars), but “traffic” is uncountable (you cannot say “two traffics”).
Step 2: Apply the Rule
If the noun is countable and plural, use fewer. If it is uncountable, use less. For example: I eat fewer cookies now. (Cookies are countable.) I eat less chocolate now. (Chocolate is uncountable.)
Step 3: Watch for Exceptions
Remember that time, money, and distance often use less even though they can be counted. This is because we treat them as a single amount. For example: I have less than five minutes. (Minutes are countable, but “less than” is standard.)

Common Mistakes with “Fewer” and “Less”
- Mistake 1: Using “less” with countable nouns. ❌ I have less apples. ✅ I have fewer apples.
- Mistake 2: Using “fewer” with uncountable nouns. ❌ I need fewer water. ✅ I need less water.
- Mistake 3: Supermarket sign error. ❌ 10 items or less. ✅ 10 items or fewer. (Items are countable.)
- Mistake 4: Using “less” with people. ❌ There are less people here. ✅ There are fewer people here. (People are countable.)
- Mistake 5: Using “fewer” with time expressions. ❌ I have fewer than ten minutes. ✅ I have less than ten minutes. (Time expressions use “less” as a fixed phrase.)
Quick Summary
- Fewer = with plural countable nouns (e.g., fewer chairs, fewer days).
- Less = with uncountable nouns (e.g., less milk, less happiness).
- Less = also used with time, money, and distance as a whole (e.g., less than a dollar, less than an hour).
- Supermarket signs: “10 items or fewer” is grammatically correct, but “10 items or less” is common and accepted in informal English.
- Quick test: If you can count it, use fewer. If you cannot, use less.

Answers:

Conclusion
Now you know the difference between fewer and less like a pro. Remember: countable nouns take fewer, uncountable nouns take less, and time/money often take less. Next time you see a supermarket sign that says “10 items or less,” you can smile and know the grammar rule—even if the sign is wrong. Keep practicing with the exercises above, and soon it will become second nature.
FAQ
1. Is it ever correct to say “less people”?
No, “less people” is grammatically incorrect because “people” is a countable noun. The correct phrase is “fewer people.” However, in very informal speech, some native speakers might use “less people,” but it is not standard English.
2. Why do supermarket signs say “10 items or less”?
Supermarkets use “10 items or less” because it sounds more natural and friendly in everyday speech. While “10 items or fewer” is grammatically correct, many businesses prefer the common usage. This is a classic example of how language evolves and how informal usage sometimes overrides strict grammar rules.
3. Can I use “less” with countable nouns in any situation?
Yes, but only in specific cases. Use “less” with countable nouns when they are part of a fixed phrase like “less than” (e.g., less than five days) or when the noun is treated as a single amount (e.g., less than a mile). Also, use “less” with singular countable nouns like “less sugar” (sugar is uncountable in this context).
4. What is the best way to remember the difference?
A simple trick: think of the word “countable” and the letter “F.” Fewer starts with F, and you use it for things you can count. Less is for everything else. Another way: remember the phrase “fewer pieces, less stuff.” Pieces are countable (fewer pieces), and stuff is uncountable (less stuff).
