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
