10 Ways to Say Silly & Dumb in Spanish | Tell Me In Spanish (2024)

Just like in any other language, there are different ways to say dumb in Spanish and even though this vocabulary is extremely tempting to call or describe your friends, the truth is that these words also allow you to refer to foolish situations or actions.

Since this vocabulary can be quite helpful, in this article, I’ve compiled a list of 10 common ways to say dumb in Spanish. In addition to examples, I’ve also included some descriptions so you know how and when to use each one of these words.

By the end of it, you’ll have a wide range of options to say ‘dumb’ and ‘silly’ in Spanish.

1. Menso – Silly / Dork

In Latin American Spanish, menso is one of the most common ways to say ‘silly’, ‘dork’ or ‘dumb’. Although nobody likes to be called silly, ‘menso’ is not a rude or a curse word. In addition to qualifying people, this word can also be used to talk about objects or situations.

‘Menso’ refers to singular masculine people or things. As a result, you’ll need to use mensa when referring to feminine subjects and plural forms when talking about more than one person. Here are some examples of how to use this word:

[Subject] + [verb conjugated] + (adv) + [menso]

Carlos y Agustín son muy mensos.
Carlos and Agustin are very silly.

No sean mensas, dejen que Caro las ayude.
Don’t be dumb, let Caro help you guys.

La neta, la película está muy mensa, no la veas.
To be honest, the movie is very dumb, you shouldn’t see it.

Notice that, in Spanish, when using menso (and any other adjective), you can precede this word with qué as a way to give your opinion or reaction to someone’s behavior or actions.

¡Qué + menso + (verb conjugated)

¡Qué mensa estás!
You’re such a dork!

¿Escuchaste lo que dijo Luke? ¡Qué menso!
Did you hear what Luke said? He’s so dumb!

2. Tonto – Dumb / Fool

As you may already know, tonto is one of the most common ways to say ‘dumb’ in Spanish. ‘Tonto’ can express that a person is not very smart or is a little bit naive. So, depending on the context, it can be translated as ‘dumb’, ‘fool’, ‘foolish’, ‘silly’, ‘slow’, ‘naive’, ‘dummy’ or ‘stupid’.

Remember that, as an adjective, tonto has a feminine form (tonta) and plural forms (tontos, tontas) that will be used depending on who you’re referring to. Below is a phrase structure that you can use to apply this word. If you want, you can intensify your sentence by using an adverb.

[Subject] + [verb conjugated] + (adv) + (tonto)

No seas tonto, Charlie, no te conviene renunciar.
Don’t be a fool, Charlie, you don’t want to quit.

Jackson es muy tonto para aprender idiomas.
Jackson is very dumb at learning languages.

Cuando era más chica, era muy tonta y confiaba en todos.
When I was younger, I was very dumb and I trusted everyone.

Just like in English, in Spanish, you can use this word as a noun. To put it in lay terms, tonto (and all its forms) can be used as a way to call or name a person.

Esta tonta perdió mi teléfono.
This dummy lost my phone.

No, tonto, ¡eso no va ahí!
No, silly, that doesn’t go there!

3. Tarado – Fool / Moron

Even though you may not know this word, tarado is another word that speakers use as a way to say ‘dumb’ in Spanish. ‘Tarado’ is not a bad word, but since it implies that something is defective (in this case, your intelligence), it can be a slightly aggressive way to say ‘dumb’. As a result, you may want to limit its use to your friends.

With this meaning, ‘tarado’ is close in meaning to ‘fool’, ‘moron’, ‘stupid’ or ‘dumb’ and it’s more popular in Latin American Spanish. Notice that you can either use this word to describe someone (adjective) or as a way to call them (noun).

[Tarado] + [complement]

Qué tarada, se me olvidaron las llaves.
So stupid, I forgot my keys!

¡Tarados, se van a lastimar!
You’re going to hurt yourselves, you fools!

El novio de Sally está muy tarado.
Sally’s boyfriend is so foolish.

Oye, tarado, ¿dónde dejaste mi cartera?
Where did you leave my wallet, moron?

Take Note: In Castilian Spanish, tarado can be used to express that a person is mad or crazy.

4. Bobo – Dumb / Silly

Bobo is a cutesy and almost sweet way to say ‘dumb’ in Spanish. Although this word is quite popular among women and children, men can also use it if they don’t want to sound offensive or aggressive when calling someone dumb.

Just like ‘tonto’, bobo also implies some degree of naivety. Depending on the context, it can be translated as:

  • Dumb
  • Dummy
  • Silly
  • Fool / Foolish

[Subject] + [determiner] + [bobo] + [complement]

¡Qué libro tan bobo!
What a foolish book!

El bobo de mi cuñado chocó mi carro.
My dumb brother-in-law crashed my car.

Esta boba no sabe qué son los tacos.
This dummy doesn’t know what tacos are.

Tu novia es muy boba, la verdad.
Your girlfriend is very silly, to be honest.

Son unos bobos, la comida está deliciosa.
You guys are fools, the food is delicious.

Notice in the examples above that, depending on how it’s being used, bobo can be preceded by adverbs or nouns that allow you to intensify the word or to indicate who you’re talking about.

5. Estúpido – Stupid / Silly

As you may imagine, estúpido is the direct translation of ‘stupid’. This word can also be used to describe that someone or something is silly in Spanish. Even though this is not a bad word, it can be perceived as too aggressive when used to qualify a person.

For that reason, you may want to use ‘estúpido’ among your friends. Here are some examples of how to use this word:

[Subject] + [verb conjugated] + (adv) + [estúpido]

Güey, no seas estúpido, te vas a care.
Dude, don’t be stupid, you’re going to fall.

Los chavos de mi clase son muy estúpidos.
The boys in my class are very stupid.

Qué estúpida estuvo la conferencia de hoy.
Today’s lecture was very silly.

In informal contexts, people also use estúpido and its feminine form estúpida as a funny way to call or name their friends. This is so popular that it is actually used to create memes in Spanish. In this context, ‘estúpido’ can be translated as ‘idiot’.

¡Estúpida! Me rompiste el celular.
Idiot! You broke my phone.

¡Oye, estúpido, cóntestame!
Hey, you idiot, pick up the phone!

6. Mentecato – Dumb / Moron

Mentecato is a word that you can use in Spain and Colombia to say ‘dumb’. Although other countries may also be familiar with this term, the truth is that it can be considered a very formal and old-fashioned term. ‘Mentecato’ means ‘dumb’, ‘moron’, ‘stupid’, ‘idiot’, and ‘fool’.

Unlike other words on this list, this term is more commonly applied to refer to people. Here are some examples of how to use this word:

[Subject] + [determiner] + [mentecato] + [complement]

La novia de Charlie es una mentecata.
Charlie’s girlfriend is dumb.

Tu primo es un mentecato.
Your cousin is such an idiot.

Estos mentecatos reprobaron español.
These morons failed Spanish.

Dejen de comportarse como unas mentecatas y vámonos.
Stop acting like morons and let’s go.

7. Lelo – Dummy / Fool

Even though they’re popular terms, most Spanish learners don’t know that lelo and lela are also common ways to express that something or someone is silly or dumb in Spanish. These words can be translated as ‘dummy’, ‘fool’, ‘moron’, ‘stupid’ or ‘dull’.

Like other terms from this list, ‘lelo’ and ‘lela’ can be used either as an adjective or as a noun. Here are some examples:

[Subject] + [determiner] + [lelo] + [complement]

Eres una lela, llevo esperándote horas.
You’re such a fool, I’ve been waiting hours for you.

Este lelo no me dijo que hoy teníamos examen.
This dummy didn’t tell me that we had a test today.

Esas películas se me hicieron muy lelas.
To me, those movies were too dull.

No sean lelos, si no vamos a la escuela, vamos a reprobar.
Don’t be stupid, if we don’t go to school, we’re going to fail.

Notice that when you’re describing or qualifying an object or a person (underlined examples), you need to use a verb (in this case, ‘ser’). However, you won’t do this when using ‘lelo’ to call or name a person (example #2).

Take Note: Many Spanish learners confuse lelo and lela with object pronouns. But remember that when having double object pronouns in a sentence le will change to se to avoid confusing these pronouns with ‘lelo’ and ‘lela’ which we just learned mean ‘dumb’.

8. Bruto – Idiot / Stupid

In Spanish, bruto is a word with multiple meanings. One of its most common uses is to express that a person is clumsy or not very smart. As a result, in this context, ‘bruto’ is close in meaning to ‘idiot’, ‘stupid’, ‘ignorant’ or ‘thick’.

With this meaning, ‘bruto’ works as an adjective. Here are some phrase structures with the elements that you need to use:

[Subject] + [‘ser’ conjugated] + [bruto]

No sean brutos, se van a caer.
Don’t be stupid, you guys are going to fall.

Soy muy bruto para las matemáticas.
I’m very stupid at math.

Esas chicas son muy brutas, no discutas con ellas.
These girls are very ignorant, don’t argue with them.

Instead of using ‘bruto’ with a verb, you can also use it in a single expression as a way to react or give your opinion about someone’s actions. Notice that in this context, you can place this expression either at the beginning or end of a sentence.

¡Qué bruta! Se me olvidó pagarle a Jenny.
I’m such an idiot! I forgot to pay Jenny.

Agustín y James reprobaron español, ¡qué brutos!
Agustin and James failed Spanish, they’re such idiots!

Take Note: In other contexts, ‘bruto’ can be used to talk about earnings, raw materials or to express that a person is violent. So, make sure you pay attention to the context where this word is being applied.

El sueldo mensual bruto es de $4,750 USD.
Your monthly gross salary is $4,750 USD.

9. Güey – Dumb / Silly

In Mexican Spanish, güey or wey is one of the most popular ways to say ‘dumb’. Since this is a slang word, it’s only suitable for informal situations. With this meaning, ‘güey’ is close in meaning to ‘dumb’, ‘silly’, ‘idiot’ or ‘fool’ and it’s commonly used to describe people.

Keep in mind that, even though it’s working as an adjective, ‘güey’ doesn’t have a feminine form. Also, with this meaning you’ll need to use the verb estar or ser and, if you want to intensify your sentence, you can add some adverbs. Here is how you do it:

[Subject] + [verb conjugated] + (adv) + güey

Luisa está muy güey, la neta.
Honestly, Luisa is very silly.

¡Qué güey estás! ¿Por qué escribiste esto?
You’re such an idiot! Why did you write that?

¡No seas güey! A Mónica no le gustan las flores.
Don’t be silly! Mónica doesn’t like flowers.

Están bien weyes si creen que sus papás no se van a enojar.
You’re very dumb if you think that your parents are not going to be angry.

Take Note: Güey is a very rich word in Mexican Spanish. As a result, its meaning can change depending on how it is being applied.

10. Necio – Fool / Dumb

Necio is another common word that you can use to say ‘dumb’ or ‘silly’ in Spanish. This word is slightly more common in Castilian Spanish and you can also see it in formal contexts such as books, movies, or tv shows. ‘Necio’ can be translated as ‘fool’, ‘dumb’, ‘silly’ or ‘foolish’.

Depending on how it’s being used, necio and its feminine form necia can work either as an adjective or as a noun. Here are some examples of how to use this word.

[Subject] + [verb conjugated] + (determiner)+ [necio]

¡Necios! Se van a perder.
Fools! You’re going to get lost.

No seas necia y escucha a tu mamá.
Don’t be dumb and listen to your mom.
