Write down this explanation in your notebook.
Adjectives describe nouns.
Adverbs describe verbs.
To form regular adverbs, add -ly to the adjective. Words ending in -y change to -ily. For example, easy becomes easily.
HOWEVER!
Some adverbs are irregular! The adjectives are in blue and the adverbs are in red.
Example sentences:
Good tells us about the singer and well tells us HOW he sings.
