Bone and Bona
What is the difference between the two? Does "bone" mean "well" as in "the boy cooks well"? And "bona" means "good" as in "this is very good coffee"? Or do I not have it right at all?
After a whole two days of Esperanto, my understanding is that 'bone' (and anything else that ends in '-e') is an adverb, and bona (and anything else that ends in '-a') is an adjective; the former only modifies a verb, and the latter, a noun. So I think you are entirely correct in your examples.
