Adverb vs. adjective

Bien is an adverb. Bueno/a is an adjective. Ta-da! Ok, let me elaborate a little bit.

Bien, the adverb...

An adverb is a word that modifies a verb, another adverb, an adjective or a phrase or sentence. But NOT a noun.

An adverb typically answers the question “how,” “in what way,” “when,” “where,” and “to what extent?”


how to use bien

Q1: How are you?

No estoy bien. => I am not well.

Q2: How is your vision?

No veo bien, necesito anteojos. => I can’t see very well, I need glasses.

Q3: How did you sleep?

Dormí muy bien anoche. => I slept very well last night.

Bueno/a, the adjective...
An adjective is a word that modifies nouns. This means it will have to match the noun in number and genre.

Now that we have established the main difference between bien and bueno/a, let’s look at each one individually (and we’ll get to buen -don’t worry- I haven’t forgotten).


Esta receta es buena. => This recipe is good.

El artículo es bueno. => This article is good.

Los perros del vecino son buenos. => The neighbor's dogs are good.

When to Use Bien

Write in spanish

Bien is probably one of the first words that pops into your mind when it comes to the Spanish language.

A: ¿Cómo estás? => B: Bien.

In this case bien means “well,” but in other cases it can mean other things.

Remember, bien is an adverb, so it can modify a verb, another adverb, an adjective or a phrase but it can also hold its own ground.

Let’s look at common uses of the word bien.

  • Ok

In many cases, bien is used to convey an affirmative answer.

For example:

A: ¿Vamos a cenar al restaurante nuevo? => B: ¡Está bien!

A: ¿Vamos de camping el fin de semana próximo? => B: ¡Está bien!

Spanish phrases for Restaurants
bueno vs. bien
  • Very or Really

Insert bien where the words “very” or “really” would go.

El melón está bien dulce. => The melon is very sweet.

La cerveza es más rica cuando está bien fría. => Beer is tastier when it’s really cold.

  • Mood or Health

Bien will come up when you are talking about someone’s mood or health.

Let’s go back to our first example.

Spanish mistakes

A: ¿Cómo estás?  B: Bien, gracias. =>

A: How are you? B: I’m fine/well, thank you.

A: ¿Cómo te sientes hoy? B: Bien, ya no tengo fiebre. => 

A: How are you feeling today? B: I feel well, I don’t have a fever anymore.

  • Something Works/Doesn’t Work Properly

Whether it be technology (your computer, cell phone, other gadgets, or your car, etc.), bien is used when talking about proper/improper functioning of these things.

For Example: Mi computadora no funciona bien. => My computer doesn’t work properly.

When to Use Bueno/a

Bueno/a is a bit of a tough cookie.

Depending on the country, bueno/a can be used for many different things. Remember, bueno is an adjective, and it modifies nouns. It means “good,” for the most part.

But doesn’t buen also mean “good?”

The main difference with buen is that bueno must be used after the noun or verb it modifies. For instance, “La película es buena.”

learning a second language
In contrast, buen always precedes a masculine noun.

El buen vino es una maravilla.

Let’s look at common uses of the word bueno.

  • Good

This is probably the most common use of bueno.

Este libro es muy bueno.

  • Hello

In some Latin American countries like Mexico people use the word bueno to answer the phone.

(Riiiing…) “Bueno?”

Yep, it doesn’t seem to make a whole lot of sense, but keep in mind that greetings and certain expressions can create confusion if you try to translate them literally to English!

  • “Alright” - In Various Tones

Bueno will come in handy if you’re trying to calm the waters.

when to use bueno

“Te olvidaste de comprar tomates!”

“Bueno, no te enojes. Regreso a la tienda y los compro.”

“Yo soy una persona extremadamente buena.”

“Bueno, bueno, no exageres…”

  • Ok and Yes

A: “Ve a limpiar tu cuarto por favor.”  =>  B: “Bueno”.

A: “Papá, ¿me das dinero para salir con mis amigos?”   =>  B: “…..bueno.”

  • Filler

Just like “you know” and “I mean,” bueno is widely used at the start and in the middle of sentences.

It’s pretty safe to say that throwing a bueno here and there will help you sound like a native!

When to Use Buen

Like we mentioned before, buen is an adjective that always precedes a masculine noun and it can’t stand alone on its own.

As you may have noticed in Spanish, adjectives normally follow nouns so this is a rare exception to that rule.

Buen is a rebel in its own right! Let’s take a look at some examples.

buen vs. bueno

Este es un buen momento para dormir una siesta. => This is a good time to take a nap.

¡Buen trabajo, Juan! => Good job, Juan!

El pronóstico anuncia buen tiempo para el fin de semana. => The forecast announces good weather this weekend.

Mark es un buen compañero de trabajo. => Mark is a good co-worker.

Este es un buen libro para leer en familia. => This is a good book to read with the family.

Bien, Buen or Bueno/a with Ser and Estar

bien vs. bueno differences

Knowing when to use ser and when to use estar has proven to be a sore subject among Spanish learners.

But using ser and estar with bien, buen, or bueno/a is not that bad actually. You will discover that ser expresses a quality and estar a temporary state or end result.

As a rule, never use bien with ser. Let’s compare and contrast to evaporate any doubts.

Ella es buena. => She is a good person.

Ella está buena (slang). => She is hot (as in “good looking”).

You definitely want to have the difference between these two down and especially if you’re talking to your in-laws. 😉

Remember, it should be…

Daniel es bueno. => Daniel is a good person.

Daniel está bien. => Daniel is well.

  1. -El articulo está bien bueno (this article is really good)
    -Que buen articulo! (what a good article)
    -El articulo está bien explicado (well explained)

  2. Thanks for helping clear some of this up. However, I don’t understand how to use bueno when it’s used WITHOUT ser. Sometimes I see bueno (shortened to buen if needed) before a noun, sometimes I see bueno after a noun. Like, is there a difference between “Los buenos hombres” and “Los hombres buenos”? Is one incorrect?

  3. Zach, tus dos frases son correctas. El adjetivo “bueno” puede colocarse antes o después del sustantivo (igual que “las mujeres buenas, las buenas mujeres”). Aquí falta reseñar algo: cuando el adjetivo “bueno” precede a un sustantivo singular (masculino, por supuesto), se quita la “o”. Ej. “el buen chico”. Si se coloca el adjetivo después del sustantivo, no se quita la “o” Ej. “el chico bueno”.

  4. Great article, but I’m still confused about one thing. Is there a difference between esta bien and bueno for okay/alright or are they interchangeable?

  5. Incomparable la explicación. No tengo suficientes palabras de agradecimiento.
    Ahora a estudiar por separado para fijar conceptos. 👨‍🎓

  6. I’m still confused (actually, I don’ t think I make a mistake if I just speak without thinking, though).

    Let’s look at “I am well: / Estoy bien. “Am” is the copula, and “well” is the predicate adjective. In this sentence, “well” is an adjective modifying the the noun. It is not an adverb here, unlike in the sentence “I am doing well,” where it is an adverb modifying the verb ‘doing’ in the present continuous (though describe a state). Consider other “I am” sentences: ‘I am happy,’ ‘I am sleepy,’ and ‘ I am not playful.’ All of those terminal words are adjectives; we do not say ‘I am happily’ etc.

    It seems Spanish works differently.

  7. Wow! This is an excellent, excellent blog post. You really helped me understand when to use bien vs bueno. Tu explacion era muy buena!

  8. This article helps so much. It is very clear and goes into just enough examples. The english interpretation also really helps. Muchas gracias.

  9. This was an excellent explanation. Thank you!

    The only thing I don’t understand now is why, if “buenos” should appear after the noun it modifies, we say “buenos días” and “buenas noches.” Is this just an exception to the rules you outlined?
