POR — Usos Básicos
Learn the basic uses of POR in Spanish: cause, duration, means, exchange, and movement through. Includes fixed expressions and interactive exercises.
Understanding POR
POR is one of the two most important prepositions in Spanish (along with PARA). Its core idea is about cause, means, and passage — it looks backward at the reason or the medium through which something happens. Think of POR as answering: "Because of what? Through what? In exchange for what?"
💡 1. Causa o motivo
📖 How It Works
Use por to express the reason, cause, or motivation behind an action. It answers "Why?" or "Because of what?"
💡 English Equivalent
Usually translates as "because of", "due to", or "for (the sake of)".
Examples:
- "No fui a trabajar por estar enfermo." — I didn't go to work because of being sick.
- "Llegué tarde por el tráfico." — I arrived late due to the traffic.
- "Lo hice por ti." — I did it for you / because of you.
👤 1.1. Causa o motivo personal
📖 How It Works
Use por with pronouns to express personal choices, preferences, or what depends on a person. It's like saying "as far as I'm concerned" or "if it depends on me".
💡 English Equivalent
Usually translates as "as for me", "if it were up to me", or "for my sake".
Examples:
- "Por mí, vamos mañana." — As for me / If it's up to me, let's go tomorrow.
- "Por mí, no hay problema." — As far as I'm concerned, there is no problem.
📍 2. Lugar aproximado
📖 How It Works
Use por to refer to a general or approximate location or path rather than an exact spot.
💡 English Equivalent
Usually translates as "around", "by", or "near".
Examples:
- "Pasé por tu casa." — I passed by your house.
- "Hay una farmacia por aquí." — There is a pharmacy around here.
⏱️ 3. Tiempo aproximado
📖 How It Works
Use por to express an approximate time or a general period of the day.
💡 Day Periods
Commonly used with parts of the day: por la mañana (in the morning), por la tarde (in the afternoon), por la noche (at night).
Examples:
- "Nos vemos por la tarde." — We'll see each other in the afternoon.
- "Estudio por la mañana." — I study in the morning.
📞 4. Medio o modo
📖 How It Works
Use por to indicate the medium, channel, or method of transmission used to send or do something.
💡 English Equivalent
Translates as "by", "through", or "via".
Examples:
- "Lo envié por WhatsApp." — I sent it via WhatsApp.
- "Hablamos por teléfono." — We talked by phone.
💱 5. Intercambio o sustitución
📖 How It Works
Use por to express an exchange, trade, price, or substitution of one thing for another.
💡 Gratitude too
"Gracias por" follows this logic: giving thanks in exchange for an action or gift.
Examples:
- "Te cambio mi sándwich por tu ensalada." — I'll trade you my sandwich for your salad.
- "Pagué cien pesos por el libro." — I paid one hundred pesos for the book.
🚪 6. Vía de acceso o salida
📖 How It Works
Use por to express the place or path through which entry, exit, or passage occurs.
💡 English Equivalent
Translates as "through" or "via".
Examples:

- "Salimos por la puerta trasera." — We went out through the back door.
