In European Portuguese, por and para both translate as for, but they are not interchangeable. Para points to a purpose, a destination or a deadline, the endpoint you are moving towards. Por points to a cause, a route you pass through, an exchange or a means. The direction of the sentence is the clue.
Por and para are two of the first prepositions you meet in the Portuguese spoken in Portugal, and they cause more hesitation than almost any other pair. The reason is English: a single English for hides two different ideas, and Portuguese keeps those ideas apart with two different words.
The rule underneath the confusion is about direction. Para looks forward to a goal or an endpoint. Por looks at the reason, the path or the price along the way. Almost every tricky sentence comes back to one question: am I naming the goal, or the cause and the route?
Key takeaways
- Por and para both translate as for, but para marks a purpose, destination or deadline, while por marks a cause, route, exchange or means.
- Use para for the endpoint you are heading towards, as in este comboio vai para o Porto, meaning this train goes to Porto.
- Use por for the reason or the path, as in obrigado por tudo, meaning thank you for everything.
- Por contracts with the definite article into pelo, pela, pelos and pelas, while para does not contract in standard writing.
What is the difference between por and para?
The difference between por and para is the difference between a destination and a reason. Para names where you are going, who something is for, or by when it must happen. Por names why something happens, how you get there, or what you trade for it.
A quick test clears most cases. If you can replace for with in order to or towards, you want para. If you can replace it with because of, through or in exchange for, you want por. The test is not perfect, but it handles the sentences you say every day.
| Para (goal, endpoint) | Por (cause, route) |
|---|---|
| Purpose and intention | Reason and cause |
| Destination you head to | Movement through a place |
| The person something is for | Exchange and price |
| A deadline or due date | A means or an agent |
When do you use para?
Para points to an endpoint. Use it for purpose, for a destination you are heading to, for the person or thing something is meant for, and for a deadline. In each case para answers where to, who for, or what for.
For example, estudo para falar melhor means I study in order to speak better, and este presente é para a minha mãe means this gift is for my mother. For a deadline, o trabalho é para segunda-feira means the work is due on Monday.
When do you use por?
Por points to a cause, a path or a price. Use it for the reason something happens, for movement through or along a place, and for an exchange or amount paid. You also use por for a rate such as per day, and for the doer in a passive sentence.
For example, obrigado por tudo means thank you for everything, and fechado por férias means closed for holidays. For a route, passei por Lisboa means I passed through Lisbon, and for an exchange, paguei vinte euros por este livro means I paid twenty euros for this book.
What are pelo and pela?
Por has one feature para does not: it merges with the definite article. When por is followed by o, a, os or as, the two words contract into a single form. This happens every time, so these contractions are worth learning as a set from the start.
| Por plus article | Becomes |
|---|---|
| por + o | pelo |
| por + a | pela |
| por + os | pelos |
| por + as | pelas |
So obrigada pela ajuda means thanks for the help, and olhei pela janela means I looked through the window. Para does not contract in standard writing, although in casual speech in Portugal you will often hear it shortened to pra.
The trap: sentences that flip meaning
Because both words can translate as for, swapping one for the other changes the meaning rather than breaking the sentence. The grammar still works, but you say something you did not intend. These pairs are worth reading slowly.
| Portuguese | Meaning |
|---|---|
| isto é para ti | this is for you, it is yours |
| fiz isto por ti | I did this for your sake |
| para mim, está certo | for me, it is right, in my view |
| por mim, tudo bem | as far as I am concerned, fine |
Is por vs para different in European Portuguese?
The rule for choosing por or para is the same across the Portuguese-speaking world, so a rule you learn for Portugal also works in Brazil. What changes is the sound. In Portugal, vowels are reduced heavily, so para is often clipped to pra in fast speech, and para o can sound like prò.
There is one choice the Portuguese from Portugal makes carefully: para versus a for going somewhere. Vou para o Porto suggests you are moving there to stay, while vou ao Porto suggests a short trip you will return from.

How do you stop translating por and para?
The rule is quick to read and slow to apply. In a live conversation you have no spare moment to run the goal-versus-cause test, so por and para only turn automatic through speaking, not through more grammar tables. You have to use them, be corrected, and use them again.
