Adjectives describe nouns

An adjective tells us more about a noun, which is a person, place, or thing.

It answers the question “What kind of…?”

Examples:

• She is a quick runner. → (Quick describes runner.)
• It’s a beautiful day.
• He has a new car.

Form: adjective + noun

or be + adjective

She is happy. / The car is fast.

2. Adverbs of manner describe verbs

An adverb of manner tells you how something happens or how someone does something.

It answers the question “How?”

Examples:

• She runs quickly. → (Quickly describes runs.)
• He speaks slowly.
• They work carefully.

Form: verb + adverb

He drives dangerously.

How to form adverbs

Most adverbs of manner are formed by adding -ly to the adjective.

Adjective	→	Adverb
quick	→	quickly
slow	→	slowly
careful	→	carefully
happy	→	happily

Note: Some adverbs are irregular and don’t end in -ly:

• hard → hard

She sings well.
