Fewer and Less :
When making a comparison between quantities we often have to make a choice between the words
fewer and
less. Generally, when we're talking about countable things, we use the word
fewer; when we're talking about measurable quantities that we cannot count, we use the word
less. "She had
fewer chores, but she also had
less energy."
The managers at our local Stop & Shop seem to have mastered this: they've changed the signs at the so-called express lanes from "Twelve Items or Less" to "Twelve Items or Fewer."
Whether that's an actual improvement, we'll leave up to you.
We do, however, definitely use less when referring to statistical or numerical expressions:
- It's less than twenty miles to Dallas.
- He's less than six feet tall.
- Your essay should be a thousand words or less.
- We spent less than forty dollars on our trip.
- The town spent less than four percent of its budget on snow removal.
In these situations, it's possible to regard the quantities as
sums of countable measures.
