Comparative adjectives compare two things. Superlative adjectives compare more than two things.
Forming comparatives and superlatives:
Adjectives that have only one syllable (part) or adjectives that end in 'y' use ‘er’ to form comparatives and 'est' to form superlatives. For adjectives that end in 'y' change the 'y' to 'i' before adding 'er' or 'est'.
Old older (the) oldest
Young younger (the) youngest
Pretty prettier (the) prettiest
Long longer (the) longest
Short shorter (the) shortest
Happy happier (the) happiest
Close closer (the) closest
Adjectives with two syllables or more than two syllables do not change but instead have more in front of comparatives and most in front of superlatives.
Beautiful more beautiful (the) most beautiful
Amazing more amazing (the) most amazing
Horrible more horrible (the) most horrible
Expensive more expensive (the) most expensive
Delicious more delicious (the) most delicious
Some adjectives have very different forms of comparatives and superlatives.
Good better (the) best
Bad worse (the) worst
Little less (the) least
Much/many more (the) most
Far further (the) furthest
We can use 'than' to compare two things.
Sarah is more intelligent than Peter.
Danny is quicker than his brother.
I have less free time than you do.
Superlatives are usually used with 'the'
