# 👍🏻Sure in Spanish: fast tips to master all the options 🙂↕️

[Elena](https://blog.soyguiri.com/author/elena)  September 29 2025

In Spanish, there’s no one-size-fits-all translation for the word *sure*. Depending on the situation, you might use *claro*, *seguro*, or other expressions. In this blog, we’ll clear up the confusion and help you understand exactly when to use each one so you can sound like a native speaker! 👇🏻

## **🤔 What is the Spanish word for “sure”?**

The truth is… there isn’t only one! In Spanish, the choice depends on what you really mean. If you want to show quick agreement ✅ you’ll probably say *claro*. If you want to express certainty 🔒 then *seguro* is your word. And if you want something more formal 🎩 you might use *cierto* or *por supuesto*. You’ll see them in the next sections.

👍 Does “claro” mean “sure”?

Absolutely! *Claro* literally means “clear”, but in everyday conversations it’s used just like *sure!* or *of course*. *Claro* is for agreeing or confirming something ✅, not really for saying you’re 100% certain about a fact.

👩 *¿Quieres una cerveza?* 🍺  
👨 *¡Claro!*

It’s super common in Spain and sounds very natural. If you want to sound even more enthusiastic, you can say *claro que sí*. Apart from *claro que sí*, you’ll also hear *claro que no* when someone wants to strongly deny something.

👩 *¿Vienes mañana a la fiesta? 🎉*  
👨 *¡Claro que sí!*

👂🏻

*👩 ¿Vas a trabajar toda la tarde?* 👷🏻  
*👨 ¡Claro que no! Voy a descansar un rato.*

👂🏻

👉 **Heads-up:** Another very common phrase is *está claro* (it’s clear / it’s obvious). It is used to indicate that something is obvious or evident, as if there’s no doubt about it.

👩 *¿Crees que va a llover hoy?* ☔  
👨 *Está claro, el cielo está muy gris.*

## **🔒 Does “seguro” mean “sure”?**

Yes — but with a different flavour. *Seguro* is the word you use when you want to express certainty 🫡 or when you want to check someone’s certainty, not just agreement. You can also hear ¡seguro que sí! (definitely!) and ¡seguro que no! (definitely not!).

👩 ¿Crees que mañana será el examen sorpresa?📝  
👨 *Estoy seguro.*

*👩 ¿Vendrá María a la biblioteca?*📖  
*👨 ¡Seguro que no! Está enferma.*

👂🏻

But... what happens when you are not totally sure about? 😖 You can use por si acaso (just in case).

*👩 ¿Vas a traer abrigo?* 🧥  
*👨 Sí, por si acaso hace frío.*

👂🏻

**❓How to ask if someone is sure in Spanish**

This one is easy! You just say *¿Estás seguro?* (to a man) or *¿Estás segura?* (to a woman). In casual conversations, people often drop the verb and just say *¿Seguro?* which sounds quick and natural. Another option you’ll hear a lot is *¿De verdad?*  (*Really?),* that could have a surprise overtone.

👩 Ya h*e cerrado la puerta.*🚪  
👨 *¿Estás seguro?*

👩 *He visto a Brad Pitt en el supermercado.* 🛒  
👨 *¿De verdad?*
