Adjective or Adverb? 30 Real Examples

Adjectives and adverbs both add detail, but they do different jobs. Takeaway: use an adjective when you describe a noun or pronoun, and use an adverb when you describe a verb, adjective, another adverb, or the whole sentence. If you ask “What is this word describing?”, you can usually choose the correct form.

Review: what adjectives and adverbs do

An adjective describes a noun or pronoun. It tells us what kind of person, place, thing, or idea we mean. An adverb gives extra information about an action, quality, degree, time, frequency, place, or whole sentence. If you need the basic adjective lesson first, review this adjectives guide. For the adverb side, see the adverbs guide.

What adjectives describe

Adjectives usually describe nouns or pronouns. They answer questions such as What kind?, Which one?, How many?, or What is it like?

• a quiet room
• a quick answer
• a beautiful song
• a careful driver
• a hard problem
• a friendly teacher
• a late dinner
• a fast car
• a good idea
• a safe place

Adjectives can also come after linking verbs such as be, seem, look, feel, sound, smell, taste, and become.

• She is happy.
• The room looks clean.
• The soup tastes salty.
• The problem seems difficult.

How adverbs work

Adverbs can describe verbs, adjectives, other adverbs, or whole sentences. Many adverbs answer the question How?, but adverbs can also answer When?, Where?, How often?, or To what degree?

• She sings beautifully. (describes the verb sings)
• He answered quickly. (describes the verb answered)
• The test was really hard. (describes the adjective hard)
• He speaks very softly. (describes the adverb softly)
• Unfortunately, we missed the train. (describes the whole sentence)
• They arrived late. (adverb without -ly)
• The train moves fast. (same form adjective/adverb)

Adjective vs adverb: quick comparison

Quick summary

• Adjectives describe nouns and pronouns: a slow car, she is tired.
• Adverbs describe verbs, adjectives, other adverbs, or whole sentences: drive slowly, very tired, unfortunately.
• Many adverbs end in -ly, but not all: quickly, carefully, but fast, hard, and late.
• Some -ly words are adjectives, not adverbs: friendly, lovely, lonely, elderly.

Classic confusion pairs: good/well, quick/quickly

Some adjective/adverb pairs cause more mistakes than others. The most common ones are good/well, quick/quickly, hard/hardly, fast/fast, and late/lately. These pairs are important because the wrong choice can sound unnatural or even change the meaning.

Good vs well

Good is usually an adjective. It describes nouns. Well is usually an adverb. It describes how an action is done. However, well can also be an adjective when it means “healthy.”

• You did a good job. (Good describes the noun job.)
• You did the job well. (Well describes the verb did.)
• She is a good dancer. (Good describes dancer.)
• She dances well. (Well describes dances.)
• I feel good. (Natural for mood or general feeling.)
• I feel well. (Often means physically healthy.)

Quick vs quickly

Quick is an adjective. It describes a noun. Quickly is an adverb. It describes an action.

• He is a quick runner. (Quick describes runner.)
• He runs quickly. (Quickly describes runs.)
• Give me a quick answer. (Quick describes answer.)
• Please answer quickly. (Quickly describes the action.)
• She made a quick decision. (Quick describes decision.)
• She decided quickly. (Quickly describes decided.)

Hard vs hardly

Hard can be an adjective or an adverb. Hardly does not mean “in a hard way.” It means “almost not.” This is a common trap.

• This is a hard question. (adjective)
• She works hard. (adverb)
• I hardly know him. (almost do not know him)
• Incorrect: She works hardly. (This usually means she almost does not work.)
• Correct: She works hard.

Fast, late, and early keep the same form

Some adverbs have the same form as adjectives. These are often called flat adverbs.

• a fast car / The car moves fast.
• a late dinner / They arrived late.
• an early meeting / She arrived early.
• a high wall / The bird flew high.

Tips for choosing the correct form

To choose between an adjective and an adverb, do not start by asking whether the word ends in -ly. Start by asking what the word describes.

Tip 1: Find the word being described

• If the word describes a noun, choose an adjective: a quick reply.
• If the word describes a verb, choose an adverb: reply quickly.
• If the word describes an adjective, choose an adverb: really tired.
• If the word describes another adverb, choose an adverb: very carefully.

Tip 2: Be careful after linking verbs

After linking verbs, English often uses adjectives, not adverbs. Common linking verbs include be, seem, look, feel, sound, smell, taste, and become. You can review more examples in the lesson on linking verbs.

• Correct: She looks tired.
• Incorrect: She looks tiredly.
• Correct: The soup tastes good.
• Incorrect: The soup tastes well. (unless you mean the soup can taste things, which is not the intended meaning)
• Correct: I feel bad about it.
• Incorrect: I feel badly about it. in the intended meaning “I feel bad.”

Tip 3: Remember words that keep the same form

Some words can work as both adjectives and adverbs without changing form.

Tip 4: Do not trust -ly too quickly

Many adverbs end in -ly, but some -ly words are adjectives. This is why sentence function matters more than spelling.

• quickly — adverb: She answered quickly.
• carefully — adverb: He checked it carefully.
• friendly — adjective: She is friendly.
• lonely — adjective: He feels lonely.
• lovely — adjective: It was a lovely day.

FAQ

1. What is the main difference between an adjective and an adverb?

An adjective describes a noun or pronoun. An adverb describes a verb, adjective, another adverb, or sometimes the whole sentence. For example, a quick answer uses an adjective, while answer quickly uses an adverb.

2. Is good an adjective or an adverb?

Good is usually an adjective. It describes nouns: a good student, a good answer, a good idea. The common adverb form is well: She writes well.

3. Is well always an adverb?

No. Well is often an adverb, as in He speaks well. But well can also be an adjective when it means healthy: I feel well today.

4. Why do we say feel bad, not feel badly?

In I feel bad, the word bad describes the subject’s feeling, so it works as an adjective after the linking verb feel. Feel badly can sound like your sense of touch is poor, so it does not usually express the intended meaning.

5. Are all -ly words adverbs?

No. Many adverbs end in -ly, such as quickly, carefully, and quietly. But some -ly words are adjectives, such as friendly, lovely, lonely, and elderly.

6. Can the same word be both an adjective and an adverb?

Yes. Words such as fast, hard, late, early, and high can work as adjectives or adverbs. For example: a fast car and The car goes fast.

7. What is the difference between hard and hardly?

Hard can mean difficult as an adjective or with effort as an adverb: a hard test, work hard. Hardly means almost not: I hardly know him.

8. Do I use an adjective or adverb after look, feel, sound, taste, and smell?

When these verbs describe the subject’s state or quality, use an adjective: You look tired, That sounds strange, The soup tastes good. These are linking verb patterns.

9. What is the easiest way to choose the correct form?

Ask what the word describes. If it describes a noun or pronoun, use an adjective. If it describes an action, adjective, adverb, or whole sentence, use an adverb.
