Comparative and Superlative Adjectives
Quick answer
Comparative adjectives compare two things, while superlative adjectives compare one thing with a whole group.
Rules and examples
| Base adjective | Comparative | Superlative |
|---|---|---|
| small | smaller | smallest |
| quick | quicker | quickest |
| happy | happier | happiest |
| beautiful | more beautiful | most beautiful |
| good | better | best |
| bad | worse | worst |
Clear explanation
Use a comparative adjective when you compare two people, places, ideas, or things: 'This path is quicker.'
Use a superlative adjective when one item stands out from a group: 'This is the quickest path.'
Common mistakes
- Do not use both more and -er together. Say 'quicker', not 'more quicker'.
- Do not use both most and -est together. Say 'happiest', not 'most happiest'.
- Some common adjectives are irregular, such as good, better, best.
Mini quiz
- Comparative of sad: sadder.
- Superlative of strong: strongest.
- Comparative of beautiful: more beautiful.
Choosing -er, -est, more, or most
Short adjectives often use -er and -est: small, smaller, smallest. Longer adjectives often use more and most: beautiful, more beautiful, most beautiful. Some two-syllable adjectives can go either way depending on the word and the style.
If the word becomes awkward with -er or -est, use more or most. 'More careful' sounds natural; 'carefuler' does not.
| Pattern | Comparative | Superlative |
|---|---|---|
| One syllable | stronger | strongest |
| Ends in y | happier | happiest |
| Long adjective | more beautiful | most beautiful |
| Irregular | better | best |
Common comparison mistakes
- Use comparative forms for two things: 'This answer is clearer than that one.'
- Use superlative forms for one item in a group: 'This is the clearest answer.'
- Do not double the comparison. Use 'more careful' or 'carefuler' only if the form is accepted; in standard English, 'more careful' is correct.
- Watch irregular adjectives such as good, bad, and far.
Final summary
Comparative and superlative adjectives help you compare. Use a comparative form when two things are being compared, and a superlative form when one thing stands out from a group. The main choice is whether the adjective takes -er/-est or more/most.
When in doubt, choose the form that sounds natural, avoids double comparison, and makes the relationship clear.
