Comparatives and superlatives — Language, 11–13
Comparing is useful only when you know what is being compared and by how much. Language, 11–13 years.
Idea
A comparative compares two things: one can be faster, smaller or more careful than the other. A superlative places one thing at the top or bottom of a group: the fastest, smallest or most careful. The form must match the number of things and the quality you are measuring.
Why it matters
People compare prices, distances, results and choices because a bare description is often not enough. A comparison gives a relationship, not just a label: 12 minutes is shorter than 20 minutes. But a superlative needs a group, or it can sound impressive while hiding what the winner beat.
Worked example
Three routes take 18, 12 and 15 minutes. First compare two: 12 minutes is shorter than 18 minutes. Then compare all three: 12 minutes is the shortest route, while 18 minutes is the longest. The words change because the first statement has two routes and the second ranks a group of three.
Common trap
A common, reasonable mistake is to use the strongest form whenever something feels very good: “the best” or “the biggest”. But biggest needs a comparison group, and better normally compares two things. Also check irregular forms such as good, better, best and bad, worse, worst instead of adding the usual ending.
Outside school
You use these forms when choosing a phone, comparing sports results or reading a review. “This battery lasts longer” is useful only if you know what it is compared with. In adverts, notice whether “the fastest” names a real group and measurement, or simply tries to make a product sound superior.
