Good is an adjective. Well is an adverb (except when describing health).
- She is a good singer. (adjective describing "singer")
- She sings well. (adverb describing "sings")

Hard as an adverb means "with effort." Hardly means "almost not" — completely different.

Late vs. Lately
Late means "not on time." Lately means "recently."

Near means "close in distance." Nearly means "almost."
- The store is near the station.
