How to Say "idiot" in Spanish
The most common Spanish word for “idiot” is “idiota” — this is the most direct and common translation for 'idiot', suitable for most informal situations when you want to call someone foolish or stupid without being overly aggressive..
idiota
/ee-dee-OH-tah//iˈðjota/

Examples
¡No seas idiota! Cuidado con el coche.
Don't be an idiot! Watch out for the car.
Mi hermano a veces es un idiota, pero lo quiero.
My brother is an idiot sometimes, but I love him.
A Noun for Everyone
Unlike many Spanish nouns, 'idiota' can be used for both men and women. You just change the little word in front: 'el idiota' (for a male) and 'la idiota' (for a female).
Using in the Wrong Situation
Mistake: “Using 'idiota' in a formal or professional setting, thinking it's a mild word.”
Correction: This word is a strong insult. Save it for very informal situations, or when you're genuinely angry. Otherwise, it can be very offensive.
tonto
/TON-toh//ˈtonto/

Examples
No le hagas caso, es un tonto.
Don't pay attention to him, he's a fool.
¡Eres una tonta si crees esa mentira!
You're an idiot if you believe that lie!
El tonto del pueblo siempre contaba las mismas historias.
The village idiot always told the same stories.
Used as a Label
When you use 'tonto' as a noun, you are directly calling someone a fool. It's often preceded by 'un' or 'el' (e.g., 'Es un tonto'). Remember to use 'una tonta' or 'la tonta' for a female.
burro
/BOO-rroh//ˈbu.ro/

Examples
¡Qué burro eres! ¿Cómo pudiste olvidar las llaves otra vez?
You idiot! How could you forget the keys again?
Ese examen era muy difícil, solo un burro lo suspendería.
That exam was very difficult, only a dummy would fail it.
Using 'Ser'
Use the verb 'ser' (to be) when calling someone this name: 'Eres un burro' (You are an idiot).
estúpido
Examples
¡No seas un estúpido! Piensa en las consecuencias.
Don't be an idiot! Think about the consequences.
cretino
/kreh-TEE-noh//kɾeˈtino/

Examples
Ese cretino olvidó apagar las luces otra vez.
That idiot forgot to turn off the lights again.
No seas cretina y piensa antes de hablar.
Don't be an idiot (f.) and think before you speak.
Gender Matching
Like many nouns that describe people, 'cretino' changes based on the person's gender: 'el cretino' (male) or 'la cretina' (female).
pavo
/PAH-voh//ˈpaβo/

Examples
¡Qué pavo eres! ¿Cómo se te ocurrió hacer eso?
What an idiot you are! How did it occur to you to do that?
Mi hermano es un poco pavo cuando intenta hablar con chicas.
My brother is a bit clueless/awkward when he tries to talk to girls.
Using 'Pavo' as an Adjective
This word can also be used as an adjective (a describing word) meaning 'silly' or 'awkward.' Example: 'Está un poco pavo' (He is a bit awkward).
Gender Agreement
Mistake: “Using 'el pavo' to refer to a silly girl.”
Correction: When referring to a silly female, you must use the feminine form: 'Ella es una pava' (She is a silly girl).
payaso
/pah-YAH-soh//paˈʝa.so/

Examples
No seas payaso y compórtate seriamente.
Don't be a clown (a fool) and behave seriously.
Mi hermano es un payaso; siempre está haciendo chistes malos.
My brother is a joker; he's always telling bad jokes.
Acting as an Adjective
While technically a noun, 'payaso' is often used descriptively, just like an adjective: 'Eres un payaso' (You are a fool).
Using 'Payaso' vs. 'Tonto'
Mistake: “Using 'payaso' for someone who is genuinely unintelligent.”
Correction: 'Payaso' usually implies deliberate silliness or foolish behavior. If someone lacks intelligence, 'tonto' or 'estúpido' are more appropriate, though harsher.
bestia
/BES-tyah//ˈbes.tja/

Examples
No puedes dejarlo solo con los niños, ¡es una bestia!
You can't leave him alone with the children, he's a brute!
Se comportó como una bestia en la cena, sin modales.
He behaved like an idiot/savage at dinner, with no manners.
Gender Confusion
Mistake: “Usar 'un bestio' para un hombre.”
Correction: The word is always 'una bestia' (feminine), even when referring to a man who is acting like a brute or an idiot.
retrasado
/re-trah-SAH-doh//re.tɾaˈsaðo/

Examples
¡Qué retrasado eres! ¿Cómo pudiste olvidar las llaves?
What an idiot you are! How could you forget the keys?
indio
IN-dyoh/ˈin.djo/

Examples
¡No seas indio! ¿Cómo se te ocurre hacer eso?
Don't be an idiot! How did you think of doing that?
Se portó como un indio en la reunión y ofendió a todos.
He behaved like an uncivilized person at the meeting and offended everyone.
Used as a Noun
In this informal usage, 'indio' acts as a noun describing a person. It changes gender/number: 'la india' (the stupid woman), 'los indios' (the stupid people).
