What can I say instead of "she knows good" to indicate someone has expertise?

To convey that someone has expertise, you can use phrases like "she is knowledgeable", "she is an expert", or "she is well-informed". These alternatives clearly communicate her level of skill or understanding.

Is "she knows good" ever acceptable in English?

The phrase "she knows good" is generally considered non-standard English and may sound awkward or incorrect to many speakers. While it might occasionally appear in informal contexts or certain dialects, it's best to avoid it in formal writing or professional communication.

How does "she has good taste" differ in meaning from "she knows good"?

"She has good taste" specifically implies an appreciation for aesthetics and quality in things like art, fashion, or design. "She knows good" is a grammatically incorrect way to express a general understanding or knowledge, so the alternative is more specific and grammatically correct.
