Superlative adjectives

A1 Beginner

Superlative 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.

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

  1. 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'.

  2. 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.

  3. 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'.
