Superlative Grammar

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 adjectives	old, fast
2-syllable adjectives ending in -y	happy, easy
RULE: add "-est"	old → the oldest
Variation: if the adjective ends in -e, just add -st	late → the latest
Variation: if the adjective ends in consonant, vowel, consonant, double the last consonant	big → the biggest
Variation: if the adjective ends in -y, change the y to i	happy → the happiest

Long adjectives
2-syllable adjectives not ending in -y	modern, pleasant
all adjectives of 3 or more syllables	expensive, intellectual
RULE: use "most"	modern → the most modern expensive → the most expensive
