Describe a person or thing

An adjective describes a person or thing. Put it before a noun or after be: a careful driver; the driver is careful. Keep the adjective after looks when you describe an appearance: The room looks nice.

She’s a careful driver.

The room is quiet.

She’s a careful driver.Careful is an adjective describing the driver.

Describe an action

An adverb can tell us how an action happens: She drives carefully. Many manner adverbs add -ly to an adjective: careful → carefully; quiet → quietly. After a consonant + y, happy becomes happily. Do not add -ly to every word automatically.

She drives carefully.

They speak quietly.

Happy changes spelling before the adverb ending

happychange final y to ihappily
After a consonant + y, change y to i and add -ly: happily. This spelling pattern does not mean every adverb ends in -ly.

Two adverbs describe different aspects of driving

SpeedShe drives slowly.

Slowly tells us about the speed.

Care takenShe drives carefully.

Carefully tells us how much care she takes.

The recording combines them: She drives slowly and carefully. Slowly and carefully are not synonyms.

Good, well and fast

Use good as an adjective and well for doing an action successfully: a good cook; she cooks well. Fast can be both adjective and adverb: a fast runner; he runs fast. Do not write fastly. In She looks happy, happy describes her appearance, not how she looks at something.

He’s a good cook. He cooks well.

She’s a fast runner. She runs fast.
