Fewer vs. Less
Merriam-Webster explains the difference between fewer and less using this fun mnemonic: We all want fewer problems and less trouble.
The word “fewer” is used to refer to things that are counted, as in “fewer choices” and “fewer problems.”
- The burrito would be better with fewer beans.
- Put fewer shells in the bucket.
The word “less” is used to refer to things that are uncountable, as in “less time” and “less effort.”
- The burrito would be better with less salt.
- Put less sand in the bucket.
*If a noun is countable, it can be made plural (cat > cats). If a noun is uncountable, it remains singular (milk > milk).
