fewer or less?
As a general rule, fewer is used with things you can count (fewer meetings,fewer people), whereas less is used with things you cannot count (less time,less money). The same difference applies to the use of fewer than and less than: fewer than twenty people,less than an hour. Designations of price, age, and measurement are normally regarded as singular, the idea being that, for example, It cost less than ten dollars has to do with an amount of money rather than a number of individual dollars. The use of less where the sense of countable number is strong (You may use the express lane if you have less than eight items) is relatively common, though many object to it.
