Difference between "bien" and "bueno/buena"
I find it hard to decide when to use "bien" and when to use "buena" or "bueno" Are there some general rules to follow?
If you speak good English and don't confuse "well" with "good" My general advice to my students is use "bueno" and its variants for "good" and "bien" for "well"
I have to add this:
In popular speech we sometime use "está bien" for "It's OK or " It's good" In another comment I made on this subject, I said that I have heard some "jokers" say when commenting on a football game: "¡Estuvo bien! instead of the grammatically correct "fue bueno" Then I realized that I was one of the jokers.!!
Sometimes hit jest hain't naturel to use that highfalutin' lingo!
A very basic way to think about it is "bien" means "well" (and adverb) and bueno/a means "good" (an adjective).
So, in English, "how are you?" would be answered "I'm well (estoy bien)." The question "How was the movie?" would be answered "It was good (fue buena)."
Now, some people, when asked how they are, would say "I'm good" instead of "I'm well." That's incorrect (unless you're asking how they are at football, for example), but it's done quite frequently.
