The difference between an adjective vs adverb is simple. An adjective describes a noun or pronoun. An adverb describes a verb, an adjective, or another adverb.
Find the word being described, and you will know which one to use.
What Is an Adjective?
An adjective tells us more about a noun or pronoun. It answers which one, what kind, or how many.
- The tall girl (which one)
- An old van (what kind)
- Four cats (how many)
Adjectives usually sit before a noun. They can also follow a linking verb like be, seem, or feel: She seems tired.

What Is an Adverb?
An adverb tells us how, when, where, or why something happens. She arrived late. They went there for the party.
Adverbs can describe three kinds of words:
- A verb: She sang beautifully.
- An adjective: It was a terribly hot day.
- Another adverb: He worked very slowly.
Many adverbs end in -ly, but not all. Soon, here, and never are adverbs without it.
How to Turn an Adjective Into an Adverb
| Adjective ending | Rule | Example |
|---|---|---|
| Most words | Add -ly | quick → quickly |
| -y | Change y to i, add -ly | happy → happily |
| -le | Drop e, add y | gentle → gently |
| -ic | Add -ally | tragic → tragically |
A few words stay the same. Fast, early, late, and hard work as both: a fast car, she walks fast.
Adjective vs Adverb: How to Tell Them Apart
What word is being described? A noun or pronoun means adjective. A verb, adjective, or adverb means adverb.
| Adjective | Adverb | |
|---|---|---|
| Describes | Nouns and pronouns | Verbs, adjectives, adverbs |
| Answers | Which? What kind? How many? | How? When? Where? Why? |
| Example | The quick lunch | She ate quickly |
Linking Verbs and Other Tricky Cases
Linking verbs do not show action. They connect the subject to a description. Swap the verb with is. If the sentence still works, use an adjective.
The soup smells good. (The soup is good.)
He smells the soup carefully. (Here, smelling is an action, so we use an adverb.)
A few pairs cause most of the mix-ups:
- Good is an adjective. Well is the adverb: She plays well.
- Hard means difficult or with effort. Hardly means almost none.
- Late means not on time. Lately means recently.
- Words like friendly, lovely, and silly are adjectives that end in -ly. Say “in a friendly way” instead of “friendlily.”

Adjective vs Adverb FAQs
What is the main difference between an adjective and an adverb?
Adjectives describe nouns and pronouns. Adverbs describe verbs, adjectives, and other adverbs.
Do all adverbs end in -ly?
No. Words like soon, here, never, and very are adverbs without -ly. Some -ly words, like friendly, are adjectives.
Is “good” an adjective or an adverb?
Good is an adjective: a good book. The adverb is well: She sings well.
Can one word be both an adjective and an adverb?
Yes. Fast, hard, and late keep the same form in both roles. The word they describe tells you which role they play.
Should I say “I feel bad” or “I feel badly”?
Standard usage prefers “I feel bad.” Feel is a linking verb here, so it needs an adjective.
Are adjective and adverb rules different in British and American English?
The rules are the same. The differences are mostly in spelling, like color and colour, and in some casual speech.
Conclusion
Look at the word being described. If it is a noun, use an adjective. If it is anything else, use an adverb. Watch for linking verbs and pairs like good and well, and your writing will stay clear and correct.
