Quick answer
Por is a Spanish preposition that can mean 'for,' 'by,' 'through,' 'because of,' 'per,' or 'along,' depending on context. It often expresses cause, reason, exchange, movement through, or means — and contrasts with 'para,' which expresses purpose or destination.
What Does Por Mean in Spanish?
Por is a small but mighty Spanish preposition with no single English translation — it can mean “for,” “by,” “through,” “because of,” “per,” “along,” and more, depending on context. It is one half of the famously tricky por / para pair, both of which often translate to “for” in English yet are used very differently. Where para points forward to a purpose or goal, por tends to point backward to a cause, reason, or means.
Because por covers so much ground, the best way to understand it is to see its core uses grouped by the idea they express.
The Main Meanings of Por
| Sense | Example | English |
|---|---|---|
| Cause / reason | Lo hice por amor. | I did it out of love. |
| Because of | Llegué tarde por el tráfico. | I was late because of traffic. |
| Through / along | Caminamos por el parque. | We walked through the park. |
| By (agent) | Escrito por Cervantes. | Written by Cervantes. |
| In exchange for | Te doy diez por esto. | I’ll give you ten for this. |
| Per (rate) | 80 km por hora. | 80 km per hour. |
| Duration | Estudié por dos horas. | I studied for two hours. |
| Times (math) | dos por tres. | two times three. |
| On behalf of | Hablo por todos. | I speak for everyone. |
Por vs. Para: The Key Distinction
This is the contrast learners wrestle with most. Both can mean “for,” but the underlying idea differs:
| Use POR (cause, means, motion) | Use PARA (purpose, destination) |
|---|---|
| reason / cause: por el frío | purpose / goal: para aprender |
| exchange: gracias por la comida | recipient: un regalo para ti |
| movement through: por la ciudad | destination: salgo para Madrid |
| duration: por una semana | deadline: para el viernes |
| means: por teléfono | use / function: una taza para café |
A reliable rule of thumb: por answers “why / because of / through what?” while para answers “for what purpose / for whom / to where?”
Por for Reason and Cause
A very common job of por is to give the reason or motivation behind something:
- Lo hago por ti. — “I’m doing it for you / for your sake.”
- Gracias por todo. — “Thanks for everything.”

Por for Movement and Place
Por describes movement through, along, or around a space (vague location), versus para (a destination you head toward):
- Pasamos por el centro. — “We passed through downtown.”
- Camina por la playa. — “Walk along the beach.”
- Está por aquí. — “It’s around here.”

Frequently Asked Questions
What is the difference between por and para?
Both can translate to 'for,' but they cover different ideas. 'Por' expresses cause, reason, exchange, duration, movement through, or means ('Gracias por todo' — thanks for everything). 'Para' expresses purpose, goal, destination, or recipient ('Es para ti' — it's for you). A shortcut: por looks backward to a cause/reason, para looks forward to a purpose/goal.
Does por just mean 'for'?
No — 'for' is only one of its meanings. Por can also mean 'by' (passive agent: 'escrito por' — written by), 'through' or 'along' ('por la calle' — along the street), 'because of' ('por el tráfico'), 'per' ('por hora' — per hour), 'in exchange for' ('diez dólares por esto'), and 'times' in math ('dos por tres').
What does 'por favor' mean?
'Por favor' means 'please' — literally 'for/by favor.' It is one of the most common uses of 'por,' here expressing 'as a favor.' Other set phrases include 'por qué' (why), 'por eso' (that's why/therefore), 'por fin' (finally), and 'por supuesto' (of course).
How do I know when to use por for time?
Use 'por' for the duration of an action ('Estudié por dos horas' — I studied for two hours) and for approximate or general time ('por la mañana' — in the morning; 'por la noche' — at night). For deadlines or a specific point by which something must happen, use 'para' instead ('para el lunes' — by Monday).
How do you pronounce por?
Por is pronounced 'por,' rhyming roughly with the English 'pore' but shorter, with a tapped Spanish 'r' at the end and a clear, rounded 'o.' It is a single short syllable.
