Well and good
Well is often confused with good. Although both words have similar meanings, their grammatical properties are different.
Good is an adjective. It goes before a noun.
- She is a good singer.
Well is an adverb. It is usually used to modify a verb. In this case, well goes after the verb.
- She sings well.

Compound adjectives
Well is used for making several compound adjectives. These adjectives usually appear with a hyphen. Example: well-known

When these compound adjectives go in the predicative position (after a verb), they are usually written without the hyphen.
- She is well known for her work in television.
