COMPARISONS OF QUANTITY

To show difference:

more, less, fewer + than

Examples:

With countable nouns: more / fewer

• Eloise has more children than Chantal.
• Chantal has fewer children than Eloise.
• There are fewer dogs in Cardiff than in Bristol
• I have visited fewer countries than my friend has.
• He has read fewer books than she has.

With uncountable nouns: more / less

• Eloise has more money than Chantal.
• Chantal has less money than Eloise.
• I spend less time on homework than you do.
• Cats drink less water than dogs.
• This new dictionary gives more information than the old one.

So, the rule is:

• MORE + nouns that are countable or uncountable
• FEWER + countable nouns
• LESS + uncountable nouns

To show no difference:

as much as , as many as, as few as, as little as

• as many as / as few as + countable nouns
• as much as / as little as + uncountable nouns
