✦ Por Vs. Para

Can you explain when to use para and por? I always get them wrong :/

¡Hola! 

I answered a similar question before, and I made a Google document about this. But I’ll post it here (because I get this question a lot) with some extra things. :)

Well, first of all I don’t recommend you to learn “por and para” as “to and for” because this is not always correct, and you might get even more confused. The truth is that these prepositions don’t have an exact translation in English or any other language, so the only thing you can do is to know the uses and differences between them.

This is how I recommend you to learn them:

POR: reason, cause, method, way, durationPARA: purpose, goal

I think para is easier to understand. Para always refers to a purpose, a goal or an effect. So if you’re not sure which one to use, ask yourself “Does the next phrase after para talk about a purpose or goal? If yes, use it. If not, 80% of the times is por. (I say “80%” because this is not an official rule. This is just something I thought about to help you choose the right preposition).

Now let’s see some examples to make this clearer:

✦ por vs. para
