Por Que, Porque, Por Quê, and Porquê: A Portuguese Guide — Practice

Use por que in questions and embedded questions

Por que is common in direct questions asking why and in indirect questions such as não sei por que (I don’t know why). Here, por and que remain separate. In a question at the end of a sentence, Portuguese writes por quê with an accent on quê.

A practical check: if English why fits and the expression is not at the end of the sentence, por que is often the form you need. When it falls at the end of a direct or indirect question before punctuation, write por quê: Por que você saiu? / Você saiu por quê? / Não sei por quê.

Use porque for a reason and porquê as a noun

Porque is one word when it introduces an explanation or answer: it usually corresponds to because. Porquê is a masculine noun meaning the reason or the why; it often appears with an article, as in o porquê.

In edited writing, check which job the expression is doing before you choose the spelling. The spoken sound may not help you distinguish the forms, so use the sentence structure as your guide.

Remember: Separate por que for why, porque for because, por quê at the end of a question, and porquê when you mean the reason. Decide from the sentence’s function, not from sound.

Check your understanding

Choose the English meaning of each Portuguese example. Answer before looking back at the tables. These questions check the written examples in this guide; they are not a listening or proficiency test.

Recall the Portuguese, then say it

Read the English prompt and say a Portuguese version before opening the answer. The answer shows the example from the lesson; other natural translations may also work. Compare the meaning and the situation rather than counting a different word as automatically wrong.

Make the phrase useful to you

Choose one example you could actually use. Say it once from memory, then change one detail that fits your life, such as the person, place, time, or object. Check whether your change also needs a different verb form, article, or adjective ending. If it does, compare it with the pattern in the explanation.

Separate por que for why, porque for because, por quê at the end of a question, and porquê when you mean the reason. Decide from the sentence’s function, not from sound.
