✅ She plays well
Correct. Use well to describe an action (verb).
❌ She plays good
Incorrect. Good is an adjective, not an adverb.
The difference between good and well is one of the most common stumbling blocks in the English language. Even native speakers mix these up during casual conversation. However, once you understand the grammatical roles they play, the choice becomes clear. Good is an adjective, while well is usually an adverb. This simple distinction changes how we describe things versus how we describe actions.
The Role of “Good” (Adjective)
You should use good when you are describing a noun (a person, place, or thing). Because it is an adjective, it modifies the subject or object of a sentence. It answers the question: “What is it like?”
Usage Rules
Use good with nouns or after linking verbs (like be, seem, appear).
Examples
- This is a good book.
- Your English is good.
- The weather looks good today.
Think about it this way: You can have a good day, eat a good pizza, or be a good student. In all these cases, you are describing the thing itself.
The Role of “Well” (Adverb)
In contrast, well is an adverb. You use it to modify a verb, an adjective, or another adverb. It answers the question: “How was the action performed?”
Action Verb + Well
Did you sleep well? (Describes the sleeping)
He drives well. (Describes the driving)
If you say, “I did good on the test,” you are grammatically incorrect (though people say it often in slang). The correct phrasing is, “I did well on the test,” because doing is an action.
The “Linking Verb” Trap
This is where things get tricky. We usually associate verbs with actions (run, jump, eat). However, linking verbs describe a state of being or a sensory experience. Common linking verbs include be, smell, taste, look, feel, and sound.
Rule of Thumb: If you are describing the subject, use good. If you are describing the action of the verb, use well.
Sense Verbs
When you talk about senses, you almost always want the adjective good.
- Correct: The soup tastes good. (The soup is good.)
- Incorrect: The soup tastes well. (This would mean the soup has a mouth and is skilled at tasting things!)
- Correct: You look good. (Your appearance is pleasing.)
- Correct: You look well. (You appear healthy—more on this below.)
Health vs. Emotion: “I am Good” vs. “I am Well”
When someone asks, “How are you?”, how should you answer? Both answers are acceptable, but they carry slightly different meanings depending on the context.
I am good
This is the most common response in American English. It relates to your emotional state, general happiness, or comfort. It acts as an adjective describing you.
I am well
This specifically refers to health. If you were sick yesterday but recovered today, you represent a state of physical health. “Well” functions as an adjective here meaning “healthy.”

Real-World Examples to Practice
To lock this into your memory, let’s look at specific scenarios where these words are frequently swapped incorrectly.
✅ Say This
The team played well last night.
(Action verb “played” requires an adverb.)
I don’t feel well.
(Refers to physical health.)
❌ Not This
The team played good last night.
(Informal/Incorrect in standard grammar.)
I don’t feel good.
(Acceptable for emotions, but “well” is better for sickness.)
Remember that if you can place the word “very” before it, you are likely looking for an adjective. You can say “a very good dog,” but you cannot say “a very well dog.” Conversely, if you are answering how something happened, reach for well.
