Portuguese Question Words

The question words themselves are short and regular. The one genuinely hard part is that why and because are spelled four different ways.

The four spellings of porque

Por que in two words asks the question: Por que você está aqui?

Porque in one word answers it: Porque eu quero. Because I want to.

Por quê in two words with a circumflex is used when it ends the sentence: Você não vem, por quê?

O porquê with an article is a noun meaning the reason: Não sei o porquê.

Native speakers get this wrong constantly, so you are in good company. The first two carry almost all the everyday use.

  • Como você se chama?What is your name?
  • Por que você estuda português? Porque eu gosto.Why do you study Portuguese? Because I like it.
