Comparative adjectives

Comparative adjectives are words used to compare people and things.
Ex: I am taller than my wife.

Comparative adverbs

For comparing actions we use comparative adverbs.

Busy Busier If the adjective finishes in consonant + y then form the comparative form by replacing "y" with "i" and adding -er
