Formation of Superlative Adjectives

As with comparative adjectives, there are two ways to form a superlative adjective:
  • short adjectives: add "-est"
  • long adjectives: use "most"
We also usually add 'the' at the beginning.

Short adjectives
1-syllable adjectivesold, fast
2-syllable adjectives ending in -yhappy, easy
Normal rule: add "-est"old → the oldest
Variation: if the adjective ends in -e, just add -stlate → the latest
Variation: if the adjective ends in consonant, vowel, consonant, double the last consonantbig → the biggest
Variation: if the adjective ends in -y, change the y to ihappy → the happiest
Long adjectives
2-syllable adjectives not ending in -ymodern, pleasant
all adjectives of 3 or more syllablesexpensive, intellectual
Normal rule: use "most"modern → the most modern
expensive → the most expensive

The following adjectives have irregular forms:
  • good → the best
  • bad → the worst
  • far → the furthest

Use of Superlative Adjectives

We use a superlative adjective to describe one thing in a group of three or more things. Look at these examples:
  • John is 1m75. David is 1m80. Chris is 1m85. Chris is the tallest.
  • Canada, China and Russia are big countries. But Russia is the biggest.
  • Mount Everest is the highest mountain in the world.
If we talk about the three planets Earth, Mars and Jupiter, we can use superlative adjectives as shown in the table below:
meter (km)
12,7606,790142,800Jupiter is the biggest.
tance from Sun (million km)
150228778Jupiter is the most distant from the Sun.
