Here's an easy guideline: if you are talking (or writing!) about something that you can COUNT...then use the word "fewer." If it is uncountable, then use "less."
For example: if you are talking about apples, then you have fewer apples than someone else. If you are talking about milk, then you have less milk than you had earlier.
Count it? fewer
Not a countable item? less
So... give it a try:
She has _______________________ chocolate sauce than he does. (less)
He ate ____________________ grapes than his brother did. (fewer)
They poured _________________ cement than they had the day before. (less)
There are _____________________ leaves in the parking lot than we thought there would be! (fewer)
Are you getting the hang of it?
Here's an illustration of this in use...it annoys me that someone in charge of making signs would not edit this or know it (or care?)
|Don't be the person responsible for grammatical|
errors on a sign for all to see!!!!!
