English Grammar Rules - Comparatives and Superlatives

We use Comparatives and Superlatives to compare two or more nouns.

The formation of the comparative and superlative depends on the number of syllables in the adjective:

One-syllable Adjectives

To form the comparative, we add -er to the end of the adjective.

To form the superlative, we add -est to the end of the adjective.

Adjective	Comparative	Superlative
small	smaller	the smallest
cold	colder	the coldest
light	lighter	the lightest
short	shorter	the shortest

Remember that comparatives are often followed by than.

• London is bigger than Santiago.
• Mike is taller than John but James is the tallest.

Two-syllable Adjectives ending in -Y

To form the comparative, we remove the -y and add -ier to the end of the adjective.

To form the superlative, we remove the -y and add -iest to the end of the adjective.

Adjective	Comparative	Superlative
crazy	crazier	the craziest
happy	happier	the happiest
early	earlier	the earliest

• It was the happiest day of my life.
• My joke was funnier than your one.

Adjectives with Two or more Syllables

For Adjectives with 2 syllables (that don't end in -y) and higher (3, 4 syllables etc), we use more for comparatives and the most for superlatives.

Adjective	Comparative	Superlative
handsome	more handsome	the most handsome
nervous	more nervous	the most nervous
enthusiastic	more enthusiastic	the most enthusiastic

• My girlfriend is more beautiful than yours.
• Alex is more intelligent than you but I am the most intelligent.

Irregular Forms

Adjective	Comparative	Superlative
good	better	the best
bad	worse	the worst
far	further / farther	the furthest / farthest

• I am a better tennis player than you but Marcelo is the best.
• Steve is a worse liar than me but Adrian is the worst.

Note: Further / farther, furthest / farthest are all used for distance.

Only Further / furthest are used to mean 'additional' or 'more advanced'.

• Puerto Montt is further / farther than Valdivia is from here (in Santiago).
• If you require further information, please contact reception.

Remember that the opposites of 'more' and 'most' are 'less' and 'least', respectively.
