Portuguese Question Words: O Que, Quem, Onde, and More
The seven core question words that unlock every 'wh-' question you'll ever need to ask.
Being able to ask questions is arguably more useful than being able to answer them — a good question keeps a conversation moving even when your vocabulary runs short. Portuguese builds almost every question around a small set of question words, and this guide covers all of them with real example questions.
Key Takeaways
- Seven words cover almost every question you'll ask: o que, quem, onde, quando, por que, como, and qual.
- Por que is written as one word at the end of a sentence — porquê — a spelling quirk worth knowing.
- Qual vs. o que both mean "what," but aren't interchangeable — qual asks for a choice among options, o que asks for a definition or description.
- Question intonation matters as much as word order — Portuguese often turns a statement into a question just by raising your pitch at the end, especially in casual speech.
The Seven Core Question Words
| English | Portuguese | Example |
|---|---|---|
| What | O que | O que é isso? (What is that?) |
| Who | Quem | Quem é você? (Who are you?) |
| Where | Onde | Onde fica o banheiro? (Where's the bathroom?) |
| When | Quando | Quando você chega? (When do you arrive?) |
| Why | Por que | Por que você foi? (Why did you go?) |
| How | Como | Como você está? (How are you?) |
| Which/What | Qual | Qual é o seu nome? (What is your name?) |
"Qual" vs. "O Que": The Real Difference
This is the one that trips up even intermediate learners. Use qual when you're asking someone to choose or identify from a set of options — Qual é o seu nome? (literally "which is your name," since a name is being picked out from all possible names). Use o que when you're asking for a definition, description, or explanation — O que é isso? ("what is that thing").
The Four Spellings of "Why/Because"
This is a genuine quirk worth memorizing: Portuguese has four related forms depending on position and meaning.
| Form | Meaning | Use |
|---|---|---|
| por que | why | start of a question |
| porque | because | start of an answer |
| por quê | why | end of a question (isolated) |
| porquê | the reason | used as a noun |
