Spanish for of course comes in several common forms, each fitting different situations and levels of formality. The most widely used phrase is “claro,” a simple and versatile way to express agreement or confirmation.

“Por supuesto” is another popular option, often used in slightly more formal or emphatic contexts. Other variations include “claro que sí,” which adds extra enthusiasm, and “cómo no,” commonly heard in Latin America.

Depending on the region, native speakers may switch between these phrases naturally in conversation.

Learning Spanish for “of course” helps you sound more fluent and confident, especially in everyday interactions, casual chats, and polite responses.

How One Simple Word Changed My Spanish Forever

I still remember the first time a Spanish friend asked me something in Mexico City and I answered with a stiff, textbook “sí, por supuesto.”

She laughed — not meanly, just like I’d shown up to a barbecue in a full suit. Then she said, “Just say claro.” That one word changed how natural I sounded in Spanish more than three months of grammar drills combined.

If you’re learning Spanish and keep reaching for “of course” in your head before you speak, this is the post I wish someone had handed me two years ago.

So What’s the Actual Word?

The short answer: claro.

It literally means “clear,” but Spanish speakers use it the same way English speakers use “of course,” “sure,” “totally,” or even “duh” (depending on your tone). It’s the word you’ll hear the most, by far, in everyday conversation — in Spain, Mexico, Colombia, Argentina, basically anywhere.

There are other options too, and I ended up using all of them once I understood when each one actually fits:

• Claro – the everyday, casual go-to. Think “sure” or “of course.”
• Por supuesto – a bit more formal, closer to a textbook “of course.” You’ll hear this in interviews, presentations, or when someone wants to sound polished.
• Claro que sí – an enthusiastic “of course, yes!” Great when you really want to reassure someone.
• Cómo no – common in Latin America, especially Mexico and parts of South America. Roughly “how could I not.”
• Desde luego – heard more in Spain, a confident “of course” almost like “naturally.”
• Obvio – super casual, like saying “obviously” in English. Careful with tone, it can sound a little sarcastic.

I used to think these were interchangeable. They’re not — and mixing them up is actually one of the biggest tells that someone learned Spanish from a book instead of from real people.

The Mistake I Made For Way Too Long

For almost a year, I only used “por supuesto” because that’s what my app taught me first (I was using Duolingo, then later Babbel). It’s not wrong. It’s just… a little stiff for casual chats.

Imagine if every time your friend asked “you coming tonight?” you replied “why, of course, most certainly.” Technically correct. Extremely weird.

That’s basically what I sounded like for months. Once I switched to “claro” in casual settings, conversations with locals got noticeably smoother.

People stopped slowing down or switching to English on me as much, which — if you’ve learned a language — you know is a small but real milestone.

How I Actually Learned the Difference (Step by Step)

If you want to skip the awkward phase I went through, here’s what worked for me:

Listen before you speak. I started watching Spanish shows with subtitles — “Money Heist” (La Casa de Papel) and later some Mexican YouTubers — and I just counted how often “claro” popped up versus “por supuesto.” Claro won by a mile in casual scenes. Formal scenes (news interviews, business meetings) leaned more “por supuesto.”

Practice with real conversation apps, not just vocab apps. Vocabulary apps teach you the word. They don’t teach you when to use it. I started doing quick exchanges on HelloTalk and Tandem, specifically asking native speakers, “hey, when would you say claro vs por supuesto vs cómo no?” Every single person gave me a slightly different, very human answer — which taught me more than any app lesson.

Shadow real speech. This sounds nerdy but it works: I’d repeat sentences out loud right after hearing them in a show or podcast, copying the tone. “Claro” said flat sounds like plain agreement. “¡Claro que sí!” said with energy sounds like enthusiasm. Same base word, totally different vibe depending on delivery.

Use it in low-stakes situations first. I tested “claro” first with a barista, then with a cab driver, before ever using it with actual Spanish-speaking friends. Low pressure, quick feedback, no embarrassment if I got it slightly wrong.

Notice regional flavor. When I traveled to Mexico, “cómo no” showed up constantly, especially from older folks or in polite service settings (“¿Me puede ayudar?” “¡Cómo no!”). In Spain, I heard “desde luego” a lot more than I expected, especially from people confidently agreeing with something.

Real Examples From Actual Conversations

Here are some real exchanges I either had or overheard that stuck with me:

• Friend: “¿Vienes a la fiesta?” (You coming to the party?) Me: “¡Claro, ahí estaré!” (Of course, I’ll be there!)
• Coworker (formal setting): “¿Podría revisar el informe?” (Could you review the report?) Me: “Por supuesto, lo tendré listo mañana.” (Of course, I’ll have it ready tomorrow.)
• Taxi driver in Mexico City: “¿Me puede dejar aquí?” (Can you drop me here?) Driver: “¡Cómo no!”
• Waiter in Madrid, confirming an order: “Desde luego, señor.”

Notice how the tone shifts. None of these are wrong translations of “of course” — but using the wrong one in the wrong setting is the kind of thing that instantly signals “non-native speaker” even if your grammar is perfect.

Common Mistakes to Avoid

Overusing “por supuesto” in casual talk. It’s not incorrect, just formal. Save it for work emails, interviews, or when you want to sound extra sincere.

Using “obvio” with the wrong tone. It can come across as sarcastic or even a little rude if said flatly, similar to saying “obviously” in English with an eye-roll. Reserve it for close friends and light joking.

Forgetting that “claro” can also mean “clear,” not just “of course.” Context matters. “¿Está claro?” means “Is that clear?” not “Is that of course?” I mixed these up early on and confused a coworker for a solid ten seconds.

Translating word-for-word from English. I used to think I needed a fancier word to sound polite. Spanish speakers don’t work that way — simple and natural usually beats formal and clunky.

A Quick Tip That Actually Helped Me

Whenever I wasn’t sure which version to use, I defaulted to “claro.” It’s the safest, most universally understood option across Spanish-speaking countries, and native speakers rarely bat an eye at it regardless of the setting.

Once you’re more comfortable, you can branch out into “por supuesto” for formal moments and regional favorites like “cómo no” or “desde luego” depending on where you are or who you’re talking to.
