Bien vs bueno

Explication

This is the adverb-versus-adjective distinction. Bien is an adverb: it describes how an action happens and never changes form — habla bien ('speaks well'), todo salió bien ('it all went well'), me parece bien ('sounds good to me'). Bueno is an adjective: it describes a noun and agrees with it in gender and number — un buen trabajo, una buena idea, comida buena.

So the verb decides which one you need. Actions and the verb estar take bien: cocina bien, estoy bien ('I'm fine'). Nouns and the verb ser take bueno: es buena gente ('they're good people'), ser bueno ('to be good or kind'). A common trap is the apocope: before a masculine singular noun, bueno shortens to buen — un buen día, un buen ejemplo.

Two everyday extras: está bien is the all-purpose 'it's OK / fine / agreed'. And in much of Latin America bien colloquially intensifies an adjective — está bien caro ('it's really expensive') — while bueno on its own works as a discourse opener, roughly 'well…' or 'OK…': Bueno, empecemos.
