Using fewer or less, fill in the blanks to make each sentence correct:
a. We’ve had 10 ____ leads pan out this month.
b. I’ve been trying to make ___ errors.
c. He has ___ skill than she does.
d. She has ___ skills than he does.
Answers: a. fewer; b. fewer; c. less; d. fewer
Rule of thumb: If you can count or list the items, such as “skills,” use fewer. If you’re describing something that’s a broad concept, such as “skill,” or if you’re referring to something that can’t be counted, use less.
