For example, you might say “Este libro es bueno,” or “This book is good. "

If you’re confused, just look for the thing that’s being described as good. That’s the noun the adjective bueno needs to agree with. For example, you might say “eso es una buena señal” to mean “this is a good sign. " Since the word señal is feminine, you would use the feminine form of the word bueno. If there were several signs rather than just one, you would say “estas son buenas señales. "

For example, a single friend might lament “Un buen hombre es difícil de encontrar,” which means “A good man is hard to find. " Since the word hombre is a masculine noun, bueno is shortened to buen. However, if the word bueno appears after the masculine noun it modifies, you don’t shorten it at all. For example, “Es un informe bueno” or “It is a good report. " Bueno may generally appear before or after the noun. For example, “el libro bueno” and “el buen libro” are both correct.

For example: “Este vino es muy bueno” (This wine is very good).

For example you would say “Mi pasaporte es válido por 10 años” to mean “My passport is good [valid] for 10 years. " You may also use válido to say that something is correct or accurate. For example: “Es un texto válido. " (It is a valid text. )

Bueno is an adjective. When you say “estoy bueno,” this may be interpreted as though you are saying “I am good looking. " If you go around telling people that, they’ll think you’re egotistical. 


For example, you might say “esto no habría estado bien” to mean “that would not have been good. "

“Buenos días” could be literally translated as “good days,” but it’s used primarily to mean “good morning. " “Buenos noches” is used more like “good evening” would be used in English, as it can be both a greeting and a farewell.

Spanish is a more formal language than English, so be careful who you use this phrase with. You wouldn’t want to speak this casually to someone older than you or in a position of authority.

For example, you might say “Ese coche es buenazo” or “That car is cool. " While you may hear buenazo used to describe people, the meaning of the word is different in different countries, and may not always be complimentary. Ask someone what it means before you attempt to use it to talk about a person.
