Less for Fewer

Less for Fewer

Don’t Say:
They have less books than I have.

Say:
They have fewer books than I have.

Note:
We say less than (five, six, etc) pounds because the pounds are considered as a sum of money and not as a number of coins. less denotes amount, quantity, value, or deqree, fewer denotes number. We may have less water, less food, less money, less education, but fewer books, fewer letters, fewer friends.
