How to Use "Fewer" with Countable Nouns
The word fewer is a determiner and pronoun used exclusively with plural countable nouns (things you can count one by one, such as books, cars, or mistakes).
- Grammar Rule: Fewer + Plural Countable Noun
- Example: You have made fewer mistakes today than you did yesterday.
In this example, mistakes can be counted (one mistake, two mistakes, etc.), so you must use fewer. Using less mistakes is grammatically incorrect in formal English.
How to Use "Less" with Uncountable Nouns
The word less is used with singular uncountable nouns (mass nouns or things that cannot be counted individually, such as water, food, or time) to indicate a smaller quantity.
- Grammar Rule: Less + Uncountable Noun
- Example 1: He ate less food than me.
- Example 2: One pound is less than one kilogram.

Common Mistakes to Avoid with Fewer and Less
In informal everyday speech, native speakers often use less incorrectly with plural countable nouns. For instance, you might hear someone say:
Incorrect: There are less cars on the road at night.
Because cars are countable, this sentence is grammatically incorrect. To make it correct, you must write:
Correct: There are fewer cars on the road at night.
