How to Say "stupid" in Spanish
The most common Spanish word for “stupid” is “tonto” — use this word for general silliness or foolishness, often less offensive and sometimes implying simple-mindedness rather than outright lack of intelligence..
tonto
/TON-toh//ˈtonto/

Examples
Fue una broma tonta, pero todos nos reímos.
It was a silly joke, but we all laughed.
No seas tonto, claro que puedes hacerlo.
Don't be silly, of course you can do it.
Me siento tonta por haber olvidado las llaves.
I feel foolish for having forgotten the keys.
Matching the Noun
Like many describing words in Spanish, 'tonto' changes to match the person or thing it's describing. Use 'tonto' for masculine things ('el niño tonto') and 'tonta' for feminine things ('la idea tonta'). For groups, use 'tontos' or 'tontas'.
Forgetting to Change the Ending
Mistake: “La chica es tonto.”
Correction: Say 'La chica es tonta.' Describing words almost always need to match the gender (masculine/feminine) of the noun they describe.
estúpido
Examples
Esa fue una idea estúpida.
That was a stupid idea.
idiota
/ee-dee-OH-tah//iˈðjota/

Examples
Fue una decisión idiota vender el coche.
It was an idiotic decision to sell the car.
Me hizo una pregunta totalmente idiota.
He asked me a totally stupid question.
An Adjective That Doesn't Change Its Ending
'Idiota' is special because its ending doesn't change for masculine or feminine things. It's always 'idiota'. For example: 'un plan idiota' (a stupid plan) and 'una idea idiota' (a stupid idea).
Trying to Make it Masculine
Mistake: “Quiso hacer un chiste idioto.”
Correction: Say 'un chiste idiota'. The word 'idiota' always ends in '-a', even when it's describing a masculine noun.
bruto
/broo-toh//ˈbɾuto/

Examples
No seas tan bruto, vas a romper el juguete.
Don't be so rough, you're going to break the toy.
¡Qué bruto soy! Olvidé las llaves adentro.
How stupid of me! I left the keys inside.
Changing for Gender
Remember to change the ending to 'bruta' if you are describing a woman or a feminine object.
Bruto vs. Grosero
Mistake: “Using 'bruto' to mean 'rude' in a polite sense.”
Correction: Use 'bruto' for someone who is rough or clumsy; use 'grosero' if they are being mean or impolite with words.
animal
/a-ni-'mal//a.niˈmal/

Examples
¡Qué animal! Rompió el jarrón por no mirar.
How clumsy (or 'what an idiot')! He broke the vase because he wasn't looking.
Este conductor es muy animal, va a 140 km/h en la ciudad.
This driver is very reckless, he’s going 140 km/h in the city.
Informal Adjective Use
When used this way, animal is often used as a descriptive noun/adjective that usually means 'reckless person' or 'oaf' and is applied directly to the person being criticized.
Using the literal meaning
Mistake: “Un policía le dijo que era un animal (expecting him to be literally a non-human creature).”
Correction: This is almost always hyperbole, meaning the person is acting wildly or irresponsibly, not that they are literally a beast.
cretino
/kreh-TEE-noh//kɾeˈtino/

Examples
Fue una idea cretina cruzar la calle sin mirar.
It was an idiotic idea to cross the street without looking.
Su actitud cretina nos hizo perder el autobús.
His stupid attitude made us miss the bus.
Adjective Agreement
As an adjective, 'cretino' must match the noun it describes in both number (singular/plural) and gender (masculine/feminine). E.g., 'decisiones cretinas' (plural, feminine).
Using 'ser' vs. 'estar'
Mistake: “Using 'Está cretino' (He is temporarily acting stupid).”
Correction: Use 'Ser': 'Es cretino' (He is inherently/always an idiot). Traits that are considered defining characteristics usually use the verb 'ser'.
imbéciles
Examples
Tomaron decisiones muy imbéciles.
They made very stupid decisions.
