We use adjectives to describe nouns and pronouns. Adjectives can come before nouns or after linking verbs.

Before the noun:

- He dropped the hot plate.
- I have a black cat.
- The small boy ran down the street.
- What a beautiful view!

After a linking verb:

- He seems tired.
- The view is beautiful.
- The weather became cold.
- My cat is black.

(Linking verbs are verbs like 'be', 'become' and 'seem' which are not actions but instead link the subject to an adjective, noun or phrase that gives us more information about the subject. 

We make the comparative and superlative of adjectives by adding either '-er / -est' or using 'more / most'.

- She is tall.
- She is taller than her sister.
- She is the tallest person in the class.

Adverbs are used to describe verbs, adjectives or other adverbs. They are often (but not always) made by adding 'ly' to the adjective.

- I walked slowly ('slowly' tells us about the verb 'walk').
- They worked quickly.

We make the comparative and superlative forms of adverbs by using 'more / most'.

- She sang loudly.
- She sang more loudly than her friend.
- She sang most loudly in the class.
