The clue is the meaning. Look at these English sentences:
I've waited for two hours
The translation for the first sentence is: Este regalo es para ti. But the second sentence is translated as: (Yo) He esperado por dos horas.
Confusing?? Note that we (Spanish speakers) also find difficult to use / translate some English prepositions!
Ok, below you'll find some rules that can help you understand when to use the Spanish prepositions por and para.
POR is used:
- To express the cause of an act.
Él no duerme por el ruido del tráfico.
(He doesn't sleep because of the noise of traffic)
- To express time or duration.
Yo esperé por dos horas.
(I waited for two hours)
(NOTE: In Spain, instead of "por", to indicate time / duration, we use "durante": "Yo esperé durante dos horas" or, we can even omit it: "Yo esperé dos horas" )
- In passive sentences:
Este libro ha sido comprado por doscientas personas.
(This book has been bought by two hundred people.)
- To express idea of movement, with: around, by, along, through.
Mis hijos corren por el parque.
(My sons run through the park.)
- To express means of transportation:
Yo siempre viajo por tren.
(I always travel by train.)
(NOTE: In Spain, instead of "por", to indicate means of transportation, we also use the preposition"en": "Yo siempre viajo en tren".)
- Talking about means of communication:
Te envío el documento por fax.
(I'm sending you the document by fax.)
- With multiplications, divisions and percentages:
Cien por cien.
Tres por dos son seis.
(Three times two equals six)
These are the main situations where "por" should be use. There are also a lot of expressions with "por". Some of them are:
por casualidad = by chance
por ejemplo = for example
por favor = please
por fin = finally
por lo menos = at least
por medio de = by means of
por supuesto = of course
PARA is used:
- To mean in order to, and followed by an infinitive.
Para llegar a tiempo, tienes que correr.
(In order to [To] arrive in time, you have to run.)
- To express purpose or use of something:
Ésta es la botella para vino.
(This is the bottle for wine.)
- To show the person/thing receiving a benefit or action:
Este regalo es para María.
(This present is for Mary.)
- To indicate a destination:
La semana próxima voy para Madrid.
(Next week I'm going to Madrid.)
- To indicate a deadline or concrete time:
Necesito este informe para mañana.
(I need this report no later than tomorrow.)
I know the use of por and para may seem difficult, but my advice is: Learn all this rules and read Spanish texts; when you find por or para, try to understand the meaning of the sentence, and then, review these rules, in order to find the concrete one you can apply to the preposition. This way you'll get familiar with these two Spanish prepositions.
