Adverbs of manner (quickly, well, carefully)

When you want to say how someone does something — not just that they drive, but that they drive carefully — English uses an adverb of manner. She speaks quietly. He works hard. They sang beautifully. These small words usually come from adjectives, and most of them follow one simple pattern.

An adverb of manner describes a verb (an action) and answers the question How? — How does she speak? Quietly.

Quick shortcut: for most adverbs of manner, the adjective simply takes -ly — slow → slowly, careful → carefully, quiet → quietly. A handful of common words are irregular (you'll meet them below), but adjective + -ly covers most adverbs of manner.

Forming adverbs from adjectives

Most adverbs of manner are simply the adjective + -ly:

slow → slowly · quiet → quietly · careful → carefully · bad → badly

A few spellings change when you add -ly:

A few short adjectives keep the -y and just add -ly (shy → shyly); and one common -ic exception is public → publicly.

Irregular adverbs

A small group of everyday words don't add -ly. The most important is good, whose adverb is well:

• ✅ She's a good singer. She sings well. — in standard English, not ❌ She sings good.

A few adjectives keep the same form as the adverb — no -ly at all:

Two words need special care — they look like the adverbs of hard and late but mean something completely different:

• hardly = almost not — I hardly slept. (not the adverb of hard)
• lately = recently — Have you seen him lately? (not the adverb of late)

Where the adverb goes

An adverb of manner usually comes after the verb, or after the verb + object. The one place to avoid is between the verb and a short object:

• ✅ She speaks English fluently. / ❌ She speaks fluently English.
• ✅ He opened the box carefully. / ❌ He opened carefully the box.

When there's no direct object, it often comes straight after the verb: They waited patiently. It can also sit before the main verb for a slightly more formal feel: She carefully opened the box.

Adjective or adverb?

This is the choice that trips up almost everyone. An adjective describes a noun (a person or thing); an adverb of manner describes a verb (an action):

• a quick runner (adjective + noun) → She runs quickly. (verb + adverb)
• a beautiful voice → ✅ She sings beautifully., never ❌ She sings beautiful.

So when the word tells you how the action happens, you almost always need the -ly adverb.

There's one important exception. After be and a few "sense" verbs like look, feel, smell, taste and sound, English uses an adjective, because the word describes the subject, not the action:

• ✅ The soup smells good. (not ❌ smells well)
• ✅ You look tired. — ✅ That sounds great.

(One thing to note: well can also be an adjective meaning healthy — I feel well today — so feel well is fine too.)

Common mistakes

• ❌ She sings very beautiful. → ✅ She sings very beautifully.
• ❌ He drives too fastly. → ✅ He drives too fast.
• ❌ I speak English good. → ✅ I speak English well.
• ❌ They work very hardly. → ✅ They work very hard. (hardly means almost not)
• ❌ He speaks English perfect. → ✅ He speaks English perfectly.
• ❌ She speaks fluently French. → ✅ She speaks French fluently.

• Key irregulars: good → well; fast, hard, late, early keep the same form (never ❌ fastly).
• The adverb goes after the verb or its object, not between them: ✅ speaks English fluently.
• After be and sense verbs like look, smell, taste, use an adjective, not an adverb: ✅ It smells good.
