New students often translate everything in their head word-for-word.

This works fine for basic vocabulary, but it completely falls apart when native speakers start using idioms.

Idioms (called modismos in Spanish) are phrases that have a hidden meaning. They don’t make sense if you translate them literally. For example, in English, you say “it’s raining cats and dogs.” We don’t mean animals are falling from the sky; we just mean it’s raining heavily.

Spanish is full of these colorful, fun expressions.

If you want to understand casual conversations and sound more like a native speaker, learning a few common idioms is the best place to start.

Here are some of my favorite, essential Spanish idioms that you can start using today.

1. Tomar el pelo (to pull someone’s leg)

The literal translation of tomar el pelo is “to take the hair.”

But in Spanish, this means to trick someone in a playful way, or to joke around with them. It’s the exact equivalent of saying “I’m pulling your leg” in English. This phrase is used all over the Spanish-speaking world, from Mexico to Spain.

¿Hablas en serio? No, solo te estoy tomando el pelo.

Are you serious? No, I'm just pulling your leg.

2. Ser pan comido (to be a piece of cake)

Literally, this translates to “to be eaten bread.”

When something is described as pan comido, it means it’s extremely easy to do. In English, we use “a piece of cake” or “easy as pie.” In Spanish, they use bread!

No te preocupes por el examen. Es pan comido.

Don't worry about the exam. It's a piece of cake.

3. Estar en las nubes (to be daydreaming)

The literal translation is “to be in the clouds.”

This is very similar to the English phrase “having your head in the clouds.” You use this idiom when someone is distracted, daydreaming, or not paying attention to what’s happening around them.

Juan no escuchó a la maestra. Está en las nubes.

Juan didn't hear the teacher. He's in the clouds.

4. Costar un ojo de la cara (to cost an arm and a leg)

This translates literally to “to cost an eye from the face.”

If you buy a new phone or a fancy car and it’s very expensive, you would use this phrase. While in English we give up our arms and legs for expensive things, Spanish speakers only give up an eye!

Me encanta esa casa, pero cuesta un ojo de la cara.

I love that house, but it costs an arm and a leg.

5. Meter la pata (to mess up)

Literally, this means “to put the paw in.”

You use this expression when you make a mistake, say the wrong thing, or mess up a situation. It’s very similar to the English phrase “to put your foot in your mouth.”

Metí la pata cuando le pregunté por su exnovio.

I really messed up when I asked her about her ex-boyfriend.

6. Ponerse las pilas (to get one’s act together)

The literal translation for this one is “to put in one’s batteries.”

I absolutely love this idiom. It’s widely used in Latin America (especially Mexico, Colombia, and Argentina) and Spain. You tell someone to ponerse las pilas when they need to wake up, get energetic, or start working hard. It basically means “get your act together” or “look alive!”

Tienes que ponerte las pilas si quieres aprobar la clase.

You have to get your act together if you want to pass the class.

7. Tirar la casa por la ventana (to spare no expense)

This idiom literally translates to “to throw the house through the window.”

You use this when someone is spending a lot of money to celebrate something big, like a fancy wedding or a massive birthday party. It means “to spare no expense” or “to go all out.”

Para su aniversario, tiraron la casa por la ventana y viajaron a París.

For their anniversary, they threw the house out the window and traveled to Paris.

8. No tener pelos en la lengua (to speak one’s mind)

Literally, this means “to not have hairs on the tongue.”

Imagine having hair on your tongue-it would probably stop you from speaking clearly! Therefore, a person who “doesn’t have hairs on their tongue” is someone who speaks their mind honestly and directly, without holding anything back.

Mi abuela siempre dice la verdad. No tiene pelos en la lengua.

My grandmother always tells the truth. She doesn't hold anything back.

9. Dar en el clavo (to hit the nail on the head)

This literally means “to hit on the nail.”

Just like in English, this idiom means you got something exactly right. Whether you guessed the correct answer or figured out a difficult problem, you “hit the nail on the head.”

Tu respuesta es perfecta. Diste en el clavo.

Your answer is perfect. You hit the nail on the head.

10. Echar agua al mar (to do something pointless)

The literal translation is “to throw water to the sea.”

Think about it: the ocean already has plenty of water. Throwing another bucket of water into it won’t change anything! This phrase is used when someone is doing something completely pointless or useless.

Tratar de convencerlo es como echar agua al mar.

Trying to convince him is like throwing water into the sea.
