Superlative adjectives
A1 BeginnerSuperlative adjectives compare three or more things to identify the one with the highest degree of a quality. They are typically preceded by the definite article 'the'.
Overview
Superlatives describe an object that is at the upper or lower limit of a quality. Use them when comparing one person or thing against a whole group of three or more. For example, in a group of three friends, only one can be the tallest.
Form
the + adjective + -est OR the + most + adjective
The form depends on the length of the adjective:
- Short adjectives (1 syllable): Add -est. If it ends in consonant-vowel-consonant, double the final letter (big → biggest).
- Adjectives ending in -y: Change -y to -i and add -est.
- Long adjectives (2+ syllables): Use the most before the adjective.
Spelling and Irregular Rules
| Adjective Type | Adjective | Superlative |
|---|---|---|
| Short | old | the oldest |
| Short (CVC) | hot | the hottest |
| Ending in -y | happy | the happiest |
| Long | expensive | the most expensive |
| Irregular | good | the best |
| Irregular | bad | the worst |
Examples
Common mistakes
He is most tall man here.
He is the tallest man here.
Always use 'the' before a superlative, and use '-est' for short adjectives instead of 'most'.
This car is the most fast.
This car is the fastest.
Do not use 'most' with one-syllable adjectives.
Practice
What is the superlative form of 'small'?
Show answer
the smallest
Answer:the smallest
Why:'Small' is a one-syllable adjective, so we add the suffix '-est' and the definite article 'the'.
Complete the sentence: This is ______ (difficult) exam of the year.
Show answer
the most difficult
Answer:the most difficult
Why:'Difficult' has three syllables, so we use 'the most' before the adjective.
Correct the error: Yesterday was the baddest day of my life.
Show answer
the worst
Answer:the worst
Why:'Bad' is an irregular adjective; its superlative form is 'the worst', not 'baddest'.
