Adjectives & Adverbs
What Are Adjectives and Adverbs?
Adjectives and adverbs are describing words. They add detail to sentences, making writing more vivid, precise, and interesting. Knowing the difference between them — and how to use each correctly — is one of the most useful grammar skills you can develop.
Key Terms
| Term | Definition | Example |
|---|---|---|
| Adjective | Describes a noun or pronoun | a tall building |
| Adverb | Describes a verb, adjective, or another adverb | She ran quickly |
| Comparative | Compares two things | taller, faster, more beautiful |
| Superlative | Compares three or more things | tallest, fastest, most beautiful |
| Predicate adjective | Adjective that follows a linking verb | She is kind |
Adjectives
An adjective modifies (describes) a noun or pronoun. It tells us which one, what kind, or how many.
Adjectives can appear:
- Before a noun: a red apple, three old books
- After a linking verb (predicate adjective): The soup is hot.
Types of adjectives:
- Descriptive: beautiful, angry, heavy
- Quantitative: three, many, several
- Demonstrative: this, that, these, those
- Possessive: my, her, their
- Interrogative: which, what
Adverbs
An adverb modifies a verb, an adjective, or another adverb. It tells us how, when, where, or how much.
- Modifying a verb: She carefully folded the paper.
- Modifying an adjective: It was extremely cold.
- Modifying another adverb: He spoke very quietly.
Many adverbs are formed by adding -ly to an adjective: slow → slowly, happy → happily, careful → carefully.
Comparative and Superlative Forms
Adjectives
| Adjective | Comparative | Superlative |
|---|---|---|
| tall | taller | tallest |
| happy | happier | happiest |
| beautiful | more beautiful | most beautiful |
| good | better | best |
| bad | worse | worst |
Adverbs
| Adverb | Comparative | Superlative |
|---|---|---|
| fast | faster | fastest |
| quickly | more quickly | most quickly |
| well | better | best |
Worked Examples
Identifying adjectives and adverbs:
"The fierce storm hit the coast suddenly."
- fierce = adjective (describes the noun storm)
- suddenly = adverb (describes the verb hit)
"She gave a brilliant speech and spoke confidently."
- brilliant = adjective (describes speech)
- confidently = adverb (describes spoke)
Fixing common errors:
- Incorrect: He did good on the test.
- Correct: He did well on the test. (well = adverb modifying did)
Adjective vs Adverb: How to Choose
Ask yourself: What word is being described?
- If it is a noun or pronoun → use an adjective.
- If it is a verb, adjective, or adverb → use an adverb.
Test: She looked _____ at the painting.
- If she is looking in a certain way (manner) → adverb: carefully
- If she appeared a certain way → adjective: thoughtful (She looked thoughtful.)
Common Mistakes
- Good vs well: I feel good (adjective after feel) vs I performed well (adverb after performed).
- Forgetting -ly: She spoke soft should be She spoke softly.
- Double comparatives: more better is incorrect — use better.
- Misplacing adverbs: She only eats vegetables vs She eats only vegetables — placement changes meaning.
Tips and Tricks
- If a word ends in -ly, it is often an adverb — but not always (friendly, lovely are adjectives).
- Replace the word with very — if it works in front of an adjective or adverb, the modifier is an adverb.
- Strong, specific adjectives beat vague ones: "a dilapidated shed" is better than "a very old shed".
- Overusing adverbs (especially -ly adverbs) often signals a weak verb choice: "he shouted angrily" could become "he roared".
