An adverb of manner says how someone does something: She drives carefully. An adjective describes a person or a thing: a careful driver. So the question is always: am I describing a noun, or a verb?

Adjective or adverb

An adjective goes before a noun or after be. An adverb of manner goes with a verb.

Adjective
Adverb
He's a careful driver.
He drives carefully.
She has a quiet voice.
She speaks quietly.
The test was easy.
I passed the test easily.
  • The train was slow.
  • The train moved slowly into the station.
  • Incorrect: He drives very careful.
  • Correct: He drives very carefully.
    To say how he drives, use the adverb.

Spelling: adjective + -ly

Most adverbs of manner are an adjective + -ly. A few spellings change.

add -ly
slow → slowly, bad → badly
consonant + y
y → ily
easy → easily, happy → happily

e → y
gentle → gently, possible → possibly
-ful
add -ly

  • Please close the door gently.
  • She answered politely.
  • Incorrect: He smiled happyly.
  • Correct: He smiled happily.
    After a consonant, y changes to i before -ly.

Where the adverb goes

An adverb of manner usually goes after the verb, or after the object if there is one. It doesn't go between a verb and its object.

  • She sings beautifully.
  • He closed the door quietly.
  • They speak English very well.
  • Incorrect: She speaks very well English.
  • Correct: She speaks English very well.
    The object (English) stays next to the verb. The adverb comes after it.

Some adverbs, like quickly and slowly, can also go before the verb: He quickly closed the door.

Good and well

Good is an adjective. Well is its adverb. This is a very common mistake.

Adjective
Adverb
She's a good cook.
She cooks well.
He's a good swimmer.
He swims well.
  • You did the job well. Thank you.
  • Do you sleep well at night?
  • Incorrect: She speaks English good.
  • Correct: She speaks English well.
    Speak is a verb, so it needs the adverb well.
  • Incorrect: Our team played very good yesterday.
  • Correct: Our team played very well yesterday.

Well can also be an adjective that means "healthy": I'm not well today. I think I've got a cold.

Fast, hard, late, early: no -ly

These words are the same as an adjective and as an adverb.

  • a fast car / He drives too fast.
  • a hard job / She works hard.
  • an early train / I got up early.
  • a late lunch / The bus arrived late.
  • Incorrect: You're walking too fastly.
  • Correct: You're walking too fast.
    Fastly is not a word.
  • Incorrect: He works very hardly.
  • Correct: He works very hard.
    Hardly is a different word. It means "almost not": I hardly know him.

Look, feel, sound, taste, smell + adjective

After these verbs we use an adjective, because it describes the subject, not an action.

  • You look tired. Are you OK?
  • This soup tastes good.
  • That sounds great.
  • Incorrect: The bread smells deliciously.
  • Correct: The bread smells delicious.
    Smell here describes the bread, so use the adjective.

When look is an action (look at), use an adverb: She looked at me angrily.
