GOOD or WELL?

good	well
Good is an adjective. We use good when we want to give more information about a noun. My dog is very good. He’s a good dog. She didn’t speak very good English. Her English isn’t very good.	Well is usually used as an adverb. We use well when we want to give more information about a verb. He usually behaves very well. She didn’t speak English very well.
The exception to this can be when you talk about someone’s health. She wasn’t a well woman. And when you describe sensations. This pizza tastes / looks / smells good. If you say ‘you look good’ it means ‘You look attractive’. If you say ‘you look well’ it means ‘You look healthy’.
You might hear a reply to the question “How are you?” – I’m good. This is incorrect.
