Less or Fewer? Learn the Difference with Examples

Many learners use less for everything: less mistakes, less problems, less books. In everyday speech, you may hear this sometimes, but in careful English, especially in writing, the better choice is often fewer.

The basic difference is simple:

• Use fewer with countable plural nouns.
• Use less with uncountable nouns.

Use Fewer for Things You Can Count

If you can count the noun one by one, use fewer.

• fewer mistakes
• fewer problems
• fewer students
• fewer questions
• fewer examples

Examples:

• I made fewer mistakes in my second essay.
• There were fewer students in today’s class.
• Try to use fewer repeated words in your writing.

Here, mistakes, students, and words can be counted individually.

Use Less for Things You Do Not Count One by One

Use less with uncountable nouns or general amounts.

• less stress
• less time
• less money
• less pressure
• less information

Examples:

• I feel less stress when I practise regularly.
• We have less time than we expected.
• Use less informal language in academic writing.

You do not normally say “one stress, two stresses” when talking about general pressure. That is why less stress is correct.

Quick Comparison

Look at these pairs:

• fewer mistakes, less stress
• fewer problems, less time
• fewer books, less information
• fewer questions, less confusion

This comparison helps because you can see the noun type clearly.

Why It Matters in IELTS Writing

IELTS Writing rewards clear and accurate language. You do not need complicated grammar in every sentence, but small mistakes can make your writing feel less controlled.

For example:

• Weak: Students should make less mistakes.
• Better: Students should make fewer mistakes.

The second sentence sounds more precise.

Practise While Writing

After writing a paragraph, circle every use of less and fewer. Then ask: can I count the noun?

If yes, use fewer. If no, use less.

You can practise with random essay topics using the Essay Writing Practice Tool. While revising, check quantity words before checking advanced vocabulary.

Final Reminder

Do not overcomplicate the rule. Fewer is for countable plural nouns. Less is for uncountable nouns and general amounts. This one habit can make your sentence correction much stronger.
