Adjectives and Adverbs

What is it?

Adjectives describe nouns (people, places, things), while adverbs describe verbs, adjectives, or other adverbs. Most adverbs are formed by adding -ly to adjectives (quick → quickly, beautiful → beautifully). However, some adverbs have the same form as adjectives (fast, hard, late), and some adjectives end in -ly (friendly, lovely). Understanding when to use each is essential for accurate English.

How to form it

Subject	Positive	Negative	Question
Adjective	She is a quick learner	She is not a quick learner	Is she a quick learner?
Adverb	She learns quickly	She doesn't learn quickly	Does she learn quickly?
Adjective	He is a careful driver	He is not a careful driver	Is he a careful driver?
Adverb	He drives carefully	He doesn't drive carefully	Does he drive carefully?
Same form	She is a fast runner	She is not a fast runner	Is she a fast runner?
Same form	She runs fast	She doesn't run fast	Does she run fast?

• Adjectives describe nouns: a beautiful house, a quick answer, a careful driver
• Adverbs describe verbs: She sings beautifully, He answered quickly, Drive carefully
• Most adverbs: add -ly to adjective → quick → quickly, careful → carefully, beautiful → beautifully
• Adjectives ending in -y: change y to i + ly → happy → happily, easy → easily
• Adjectives ending in -le: change -le to -ly → simple → simply, terrible → terribly
• Same form for both: fast, hard, late, early (She is a fast runner / She runs fast)
• Adjectives ending in -ly: friendly, lovely, lonely, silly (these are NOT adverbs)

When to use it

1
Adjectives before nouns or after "be" — describing what kind
"a beautiful painting" / "The painting is beautiful." / "She is happy."
2
Adverbs after verbs — describing how the action is done
"She sings beautifully." / "He runs quickly." / "They work hard."
3
Adverbs before adjectives — to intensify or modify
"very beautiful" / "extremely fast" / "really happy"
4
Special case: linking verbs — use adjectives, not adverbs, after look/seem/feel/smell/taste/sound
"She looks happy." (not happily) / "The food smells good." (not well)
5
Good vs well — "good" is adjective, "well" is adverb (but "well" as adjective = healthy)
"He is a good player." / "He plays well." / "I feel well." (healthy)

Common mistakes

She sings beautiful.

She sings beautifully.

Use an adverb (beautifully) to describe how she sings, not an adjective.

He drives very fastly.

He drives very fast.

'Fast' is both adjective and adverb. Don't add -ly.

She looks happily.

She looks happy.

After linking verbs (look, seem, feel), use adjectives, not adverbs.

He plays good.

He plays well.

'Good' is an adjective. Use 'well' (adverb) to describe how he plays.

Quick reference

Adjectives describe nouns: a quick answer, a beautiful house
Adverbs describe verbs: She runs quickly, He drives carefully
Most adverbs: add -ly (quick → quickly, careful → carefully)
Same form: fast, hard, late, early (no -ly needed)
After linking verbs (look, seem, feel): use adjectives (She looks happy)
Good (adjective) vs well (adverb): He is good / He plays well
Don't use adverbs ending in -ly with: fast, hard, late, early
