Difference between Good and Well

In the English language, it is quite common to confuse the words “good” and “well.” A common English error is to misuse the words good and well. We commonly use the words good and well synonymously, but there is a thin line of demarcation between the two. The rule of thumb is that good is an adjective and well is an adverb. When someone says “How are you?” we either say ‘I am good’ or we say ‘I am well’, both are correct, but they do not mean the same thing. Good modifies a noun; something can be or seem good. Well modifies a verb; an action can be done well.

While I am good implies you are happy in your life, and everything is okay, I am well has nothing to do with happiness, as it implies that you are healthy, fit, or fine. While good is an adjective, well is an adverb, but it can be used as an adjective also when we talk about someone’s health. However, when you’re talking about health, well can be used as an adjective.
