What is the difference between good and well?

The Basic Difference: Adjective vs. Adverb

Good: The Adjective

Good is an adjective. Adjectives describe or modify nouns and pronouns. In other words, “good” tells us what kind of person, place, thing, or idea we are talking about. For example:

• She is a good teacher.
• This is a good book.
• He had a good day.

In each sentence, “good” describes a noun (teacher, book, day). It answers the question, “What kind of [noun]?”

Well: The Adverb

Well is usually an adverb. Adverbs describe or modify verbs, adjectives, or other adverbs. They often tell us how, when, where, or to what degree something happens. For example:

• She sings well.
• He did well on the test.
• The team played well yesterday.

Here, “well” tells us how something is done (singing, doing, playing). It answers the question, “How?”

Exceptions: When “Well” is an Adjective

While “well” is mainly an adverb, it can also function as an adjective when talking about health. For example:

• She looks well after her vacation.
• He was sick last week, but now he is well.

In these cases, “well” describes someone’s state of health, much like an adjective.

Common Mistakes and How to Avoid Them

Many English learners confuse these two words, especially after linking verbs such as “be,” “feel,” or “seem.” Here are some tips to help you use them correctly:

• Use good to describe nouns: “The food tastes good.”
• Use well to describe actions: “She cooks well.”
• After verbs that describe senses (like “feel” or “look”), use “good” for general quality, but “well” for health: “I feel good” (emotionally), “I feel well” (physically healthy).
