Por vs para: the difference you can hear
After ser and estar, this is the second trap. English turns both words into "for", so the ear gives you nothing to go on. The twenty-item lists that search results offer are hard to remember. Something else works: two questions.
Two questions instead of twenty rules
Para looks forward: to a purpose, a recipient, a deadline. The question is what for, and where to?
Por looks back: to a cause, a route, a price. The question is why, and through what?
- Estudio español para trabajar en España. - I study Spanish in order to work in Spain. (purpose)
- Estudio español por mi trabajo. - I study Spanish because of my job. (cause)
Both sentences are correct and they say different things: in the first the job is ahead, in the second it is behind and it is the reason.
Para: purpose, recipient, deadline, destination
- What for: Es para aprender. - It is for learning.
- For whom: Este regalo es para ti. - This present is for you.
- By when: Lo necesito para el lunes. - I need it by Monday.
- Where to: Salgo para Madrid. - I am leaving for Madrid.
- In someone's view: Para mí, es fácil. - To me, it is easy.
Por: cause, route, exchange, stretch of time
- Why: Lo hago por ti. - I am doing it because of you, for your sake.
- Through where: Paseamos por el parque. - We walk through the park.
- For how much: Lo compré por veinte euros. - I bought it for twenty euros.
- For how long: Estudié por dos horas. - I studied for two hours.
- By whom: Escrito por García Márquez. - Written by García Márquez.
- By what means: Te llamo por teléfono. - I will call you on the phone.
The pairs that show the difference
| Phrase | Meaning |
|---|---|
| Lo hago para ti | I am making it for you (you get the result) |
| Lo hago por ti | I am doing it for your sake, in your place (you are the reason) |
| Viajo para España | I am travelling to Spain (destination) |
| Viajo por España | I am travelling around Spain (route) |
| Es para mañana | It is due tomorrow (deadline) |
| Fue por la mañana | It happened in the morning (when) |
The first pair is the most useful one. Trabajo para él - he is my boss, I work for him. Trabajo por él - I am covering his shift, he is off sick. One letter, a completely different working relationship.
Set phrases worth learning whole
Some expressions do not follow the logic, and arguing with them is pointless:
- por favor - please
- por supuesto - of course
- por eso - that is why
- por fin - at last
- por ejemplo - for example
- para siempre - forever
- para nada - not at all
Learn them as vocabulary, not as grammar.
How to drill it
- Ask the question out loud. Before choosing, ask yourself: purpose or cause? Within a month the question disappears on its own.
- Collect pairs. Every sentence where both are possible goes into your notes twice, with both translations. Twenty such pairs beat any textbook table.
- Speak. Por and para settle not when the rule is understood but after you have used it twenty times in live speech and been corrected three times.
Frequently asked questions
Is there a short rule for por and para?
Yes: para looks forward (purpose, recipient, deadline, destination), por looks back (cause, route, price, duration). If "in order to" fits, it is para; if "because of" or "through" fits, it is por.
Why is it always "gracias por" and never "gracias para"?
You thank someone for a cause - for something that already happened. That is a backward look, so por. The same goes for por favor, por supuesto and por eso, which are easier learned whole.
How long does it take to stop confusing them?
The rule takes one lesson. The automatic choice takes a few weeks of speaking practice - this topic does not close by reading tables.
