ESL students often have trouble deciding when they should use the word ‘less’ in a sentence and when they should use the word ‘fewer’. In fact, many people incorrectly use these words who are native English speakers.
For example, in 2008, the UK’s largest supermarket group, Tesco, changed its signs after being criticised for using the word ‘less’ when it should have been ‘fewer’. The signs in their fast-track checkouts read ’10 items or less’. This was incorrect because when something can be counted individually, the correct word to use is ‘fewer’.
There is a general rule that applies to the use of ‘less’ and ‘fewer’. Like many rules in the English language, there are also some exceptions to this rule.
In English, we use ‘fewer’ to describe how small several people or things are (such as muffins, parking tickets, plates, rings, dogs, cousins, or work assignments).
Examples of the use of ‘fewer’ in a sentence:
Conversely, we use ‘less’ to describe a smaller amount of something that cannot be counted or does not have a plural. Examples include shaving cream, potato salad, rain, applause, and space.
Examples of the use of ‘less’ in a sentence:
The exception occurs when talking about ages, time, sums of money, and distance. You would use ‘less’ in these instances because you refer to total amounts rather than individual units. Also, we use ‘less’ with numbers when they are on their own.
