Adjectives and Adverbs
Grade 4 · English · Study Guide
Learn how adjectives describe nouns and adverbs describe verbs, adjectives, and other adverbs.
Adjectives and adverbs are describing words that add detail and color to your writing. Without them, sentences are plain. With them, writing comes alive!
An adjective describes or modifies a noun or pronoun. It answers the questions: What kind? How many? Which one? 'The tall, graceful dancer' — 'tall' and 'graceful' are adjectives describing the dancer (noun). Adjectives usually come right before the noun they describe, or after linking verbs: 'The soup is hot' — 'hot' is an adjective describing the soup.
An adverb describes or modifies a verb, an adjective, or another adverb. It answers the questions: How? When? Where? How often? How much? 'She ran quickly' — 'quickly' is an adverb describing how she ran. Many (but not all) adverbs end in '-ly': slowly, quietly, loudly, carefully, happily.
Adjectives can be compared using degrees. Positive: 'tall.' Comparative (comparing 2 things): 'taller' — add '-er.' Superlative (comparing 3+ things): 'tallest' — add '-est.' For longer adjectives: use 'more' and 'most' instead ('more beautiful,' 'most beautiful').
Adverbs can also be compared: 'fast, faster, fastest' or 'quickly, more quickly, most quickly.' Be careful with good/well and bad/badly — 'good' is an adjective; 'well' is an adverb. 'She is a good runner. She runs well.'
| Positive | Comparative (2 things) | Superlative (3+ things) |
|---|---|---|
| tall | taller | tallest |
| fast | faster | fastest |
| beautiful | more beautiful | most beautiful |
| good | better | best |
| bad | worse | worst |

Show answer
Answer: adverb
Adverbs can modify verbs ('ran fast'), adjectives ('very tall'), or other adverbs ('quite quickly').
Which sentence uses the superlative form of an adjective?
- She is tall.
- He is taller than his brother.
- That is the tallest building I've seen.
- The building is very tall.
Show answer
Answer: That is the tallest building I've seen.
Superlatives use '-est' (or 'most') and compare THREE or more things. 'Tallest' compares this building to all buildings seen.
'Good' is an adverb and 'well' is an adjective.
Show answer
Answer: False
'Good' is an adjective (good job, good book). 'Well' is an adverb (she sings well, he plays well).
Fun facts
- The word 'very' is actually an adverb — it modifies adjectives and adverbs ('very tall,' 'very quickly'). Many writing teachers say overusing 'very' weakens your writing!
- Some adjectives like 'unique' and 'perfect' technically have no comparative or superlative — you can't be 'more unique' or 'most perfect' because they already mean one-of-a-kind or flawless.
