Confusing Words
number vs amount
Number and amount both refer to quantity, but they are used with different types of nouns. Number is used with countable nouns — things you can count individually — for example, 'A large number of students attended the event.'
- number — Number' is used with countable things — for example, 'A large number of students joined the club.'
- amount — Amount is used with uncountable nouns — things that cannot be counted as individual units — for example, 'A large amount of research has been conducted on climate change.'
Memory rule: A quick test: can you count the items individually? If yes, use number (number of students, number of reports). If the quantity is a mass or bulk that cannot be counted individually, use amount (amount of water, amount of evidence). Common errors include 'amount of people' — since people can be counted, the correct form is 'number of people'.
