*Is it ‘less’ or ‘fewer’? Here’s an easy way to tell the difference.
The differences between ‘less’ and ‘fewer’ and ‘much’ and ‘many’ have to do with countable vs. uncountable nouns.
A countable noun is a noun with an identifiable quantity. For example:
A raindrop is a countable noun, since you can theoretically count a number of raindrops.
The rain is an uncountable noun because you can’t identify its quantity.
For countable nouns, use the term ‘fewer.’
The farther south I drive, the fewer raindrops I see on my windshield.
For uncountable nouns, use the term ‘less.’
It has been a dry winter; there is less rain than usual.
The same principle applies for many and much.
For countable nouns, use the term ‘many.’
There are many action figures on sale this weekend.
For uncountable nouns, use the term ‘much.’
The store manager says they have too much inventory in the back room.
