1. Introduction — One of the Most Common Confusions
"Good" and "well" are two of the most frequently confused words in English, not because the rule is complicated, but because "well" breaks the rule in one specific, common situation. Getting this right is a small detail that native speakers notice immediately when it's wrong, "I am good" instead of "I am well" is one of the most recognisable non-native patterns in English.
2. Quick Summary
⚡ Good vs Well at a Glance
goodAlways an adjective, describes a noun: a good film, the food is good
wellUsually an adverb, describes a verb: she sings well, he works well
well (special case)Also an adjective meaning "healthy": I am well, thank you
Common Mistake"I am good" (meant as a health response) instead of "I am well"
3. Good — Always an Adjective
"Good" describes a noun, either directly before it or after a linking verb.
Structure
Example
good + noun
a good film, a good idea, good weather
linking verb + good
The food tastes good. This looks good. I feel good.
💡
Good never describes HOW an action is performed
You cannot say "she sings good" or "he plays good," describing HOW an action happens always needs an adverb (well), never the adjective "good." See our full guide to Linking Verbs for the underlying rule.
4. Well — Usually an Adverb
"Well" describes how an action is performed, modifying a verb, not a noun.
Structure
Example
verb + well
She sings well. He plays the guitar well. This works well.
well + past participle (compound adjective)
a well-known author, a well-written essay
5. Well as an Adjective — Health
"Well" has one important exception: when talking specifically about health, "well" functions as an adjective meaning "in good health," and follows the same linking-verb rule as "good."
Sentence
Meaning
I am well, thank you.
I am in good health. (adjective)
She doesn't look well today.
She doesn't appear healthy. (adjective)
Get well soon!
A wish for someone to recover their health. (adjective)
⚠️
Good vs Well for health, both are correct, but mean slightly different things
"I am good" is common informal English meaning "I'm fine/doing okay" generally. "I am well" specifically emphasises health. Both are acceptable in casual conversation, but "well" is the more precise, traditionally "correct" answer to "How are you?"
6. Common Mistakes
❌ Incorrect
✅ Correct
Why
She sings good.
She sings well.
"Sings" is an action verb here; it needs the adverb "well," not the adjective "good."
This is a well film.
This is a good film.
Describing a noun directly always needs the adjective "good," not "well."
He plays football good.
He plays football well.
Describing HOW an action is performed needs the adverb "well."
I feel well today. (meant: generally fine, not specifically about health)
I feel good today.
For general wellbeing/mood (not specifically health), "good" is more natural and common.
