Here's a quick guide to help you choose the best way to say 'of course' based on the situation.
| Phrase | Formality | Best For | Avoid When |
|---|---|---|---|
| Claro / Claro que sí | Informal/Neutral | Everyday conversations, friendly interactions, and general use. | Never, this is almost always a safe and good choice. |
| Por supuesto | Neutral/Formal | Professional settings, showing respect, or when you want to sound confident and polite. | In very casual slang-filled chats where 'claro' might fit better. |
| Cómo no | Neutral/Friendly | Enthusiastically agreeing to requests, especially in Latin America. | In Spain, where it's less common and 'claro' is preferred. |
| Desde luego | Formal | Expressing certainty in formal contexts, especially in Spain. | Casual conversations in Latin America, where it can sound a bit stiff. |
| Obvio | Very Informal | Joking with close friends when the answer is extremely obvious. | Any situation that requires politeness, respect, or formality. |
All the sounds in 'claro que sí' and 'por supuesto' are very easy for English speakers. The Spanish 'r' in 'claro' is a simple tap, not a difficult roll.
These are fixed phrases. You don't need to worry about conjugations or gender agreement. Just memorize them as a single unit.
The main challenge isn't saying the words, but choosing the right variation for the context, formality level, and region. Using 'obvio' with your boss would be a mistake.
—¿Me puedes pasar la sal? —¡Claro que sí!
—Can you pass me the salt? —Of course!
—¿Podríamos posponer la reunión para mañana? —Por supuesto, no hay problema.
—Could we postpone the meeting until tomorrow? —Of course, no problem.
—Oye, ¿quieres venir al cine con nosotros? —¡Pues claro! Me encantaría.
—Hey, do you want to come to the movies with us? —Well, of course! I'd love to.
—Disculpe, ¿me podría indicar dónde está la estación? —¡Cómo no! Siga todo recto.
—Excuse me, could you tell me where the station is? —Of course! Go straight ahead.
Just like in English, your tone of voice is crucial. A cheerful '¡Claro!' sounds friendly and agreeable. A flat, sharp 'Claro.' can sound dismissive or sarcastic, like you're saying 'Obviously, dummy.' Always aim for a warm, positive intonation.
In many parts of Latin America, especially Mexico, 'cómo no' is more than just 'of course'. It's a marker of good service and hospitality. Hearing it from a shopkeeper or waiter feels incredibly welcoming, as if they're saying 'It would be my pleasure to help you'.
Phrases like 'desde luego' and 'por descontado' are more frequently heard in Spain. While understood elsewhere, using them might subtly mark you as a speaker of Peninsular Spanish. They often carry a slightly more formal or serious weight than the universal 'claro'.
Mistake: “Saying 'de curso'.”
Correction: Use 'claro que sí' or 'por supuesto'.
Mistake: “Using 'por supuesto' in very casual, rapid-fire conversations with close friends.”
Correction: Use 'claro' or 'pues claro'.
Mistake: “Replying with 'Obvio' to a boss or an older person.”
Correction: Use 'Por supuesto' or 'Claro que sí'.
When in doubt, you can't go wrong with 'Claro que sí' or 'Por supuesto'. Master these two first. 'Claro que sí' is slightly more conversational, while 'Por supuesto' is a perfect neutral-to-formal default.
Pay attention to what native speakers around you are using. If you're in Mexico and hear 'cómo no' all the time, start incorporating it to sound more local. If you're in Spain, listen for 'desde luego'.
To say the opposite, the most common phrases are 'Claro que no' and 'Por supuesto que no'. They are direct, clear, and used in the same way as their positive counterparts.
'Cómo no' is a hallmark of Mexican politeness and hospitality. It's used constantly in service industries and everyday life to convey a cheerful willingness to help. It's much more common here than in other regions.
Spain uses a wider variety of formal alternatives like 'desde luego'. The phrase 'faltaría más' is also uniquely Spanish and can mean 'of course!' in response to a request, implying 'you don't even need to ask'.
The use of 'obvio' is extremely widespread in casual, especially younger, circles. It's often said with a certain flair. 'Claro' remains the standard for all other situations.
The phrases are the same as elsewhere, but the rhythm and speed of delivery are key. The enthusiastic and friendly '¡Claro que sí!' fits perfectly with the generally warm and open culture.
Claro que sí
WhatsApp, social media comments, text messages.
—Vienes mañana? —Claro q si!
—You coming tomorrow? —Of course!
Obvio
Used among younger people on platforms like Instagram, TikTok, and WhatsApp.
—La peli estuvo genial, no? —Obvi
—The movie was great, right? —Obvi
¡Muchas gracias!
Thank you very much!
De nada, con gusto.
You're welcome, with pleasure.
Ah, perfecto. Gracias por confirmar.
Ah, perfect. Thanks for confirming.
No hay problema.
No problem.
This connects the Spanish word to a similar-sounding English word, making it easier to remember its meaning of certainty and affirmation.
This trick links the Spanish word to its English cognate 'supposed', creating a logical bridge to its meaning of being natural or expected.
This is the natural response after someone thanks you for doing something you agreed to with 'claro que sí'.
Saying 'of course' is a form of agreement. Learning phrases like 'estoy de acuerdo' expands your ability to share opinions.
This phrase often accompanies 'of course' when agreeing to a request, like 'Por supuesto, no hay problema'.
'Okay' ('vale', 'está bien') is another essential agreement word that you'll use in similar situations as 'claro'.

Think of 'Claro' as 'Sure!' and 'Por supuesto' as 'Of course'. 'Claro' is more common in casual, everyday speech, while 'Por supuesto' works in any situation but can sound slightly more formal. When in doubt, both are safe choices, but 'Claro' is friendlier and more relaxed.
Yes, you can, but 'Claro que sí' or 'Por supuesto' adds more enthusiasm and confirmation. Just saying 'Sí' can sometimes sound a bit blunt or low-energy, while 'Claro que sí' means 'Yes, absolutely!' and conveys more positivity.
Almost never. Unlike in English where 'Why not?' can sometimes be sarcastic, 'Cómo no' in Spanish is overwhelmingly a genuine and friendly expression of willingness. It's one of the most positive phrases you can use to agree to something.
It's very simple! Just add 'no' at the end. The two most common ways are 'Claro que no' and 'Por supuesto que no'. They are the direct opposites and are used just as frequently.
'Por supuesto' is an excellent choice for professional writing as it is polite, clear, and universally understood. 'Desde luego' is another strong, formal option, especially if you're communicating with someone in Spain.
This is a tricky phrase mostly used in Spain. In response to a request for permission ('May I sit here?'), '¡Faltaría más!' means 'Of course, please do!'. It implies the answer is so obvious you shouldn't have had to ask. However, be careful, as it can also be used to express indignation ('Well, I never!'), so context and tone are everything.
