As if math is not already a challenge to most people, distinguishing the terms amount and number from each other when describing quantity adds to the struggle. But before we discuss the differences between the two words, we should focus on the concepts of count nouns and mass nouns first.
Count nouns or countable nouns are anything that can be counted, whether singular or plural, such as books, a pen, and people riding a bus. On the other hand, mass nouns are anything that cannot be counted and are always written in the singular form, such as water, advice, and garbage. In order to express them in plural form, they are paired with words expressing a plural concept to help writers be more specific.
Examples:
- Water – buckets of water
- Advice – pieces of advice
- Garbage – bags of garbage
As a noun, the word amount refers to “a quantity of something,” and is particularly used with mass nouns.

Now that we have determined the differences and uses amount and number, it would be easier to utilize them in our writing. A trick for remembering would be to note that amount is for mass nouns because they both have an m in their spelling while number is for count nouns because we count using numbers.
