When you didn't quite catch what someone said — or you caught it perfectly and simply can't believe it — you don't ask a fresh question. You bounce part of their sentence back at them. In English: "You went where?" In Brazilian Portuguese this is the echo question (pergunta-eco), and it works on a principle that surprises English speakers: the question word stays exactly where the answer would go, with heavy stress, instead of jumping to the front of the sentence.
This page is about that one structural fact and everything that follows from it. Echo questions are everywhere in spoken Brazilian Portuguese, and getting them wrong makes you sound like you're reading from a textbook rather than reacting to a real conversation.
The core rule: the question word stays "in situ"
A normal wh-question in Brazilian Portuguese fronts the question word, just like English:
O que você comprou?
What did you buy?
An echo question does the opposite. It keeps the structure of the original statement (subject – verb – object) and simply drops the question word into the slot where the missing information belongs, hitting it with strong, often rising, stress:
Você comprou o quê?!
You bought WHAT?!
Linguists call this leaving the wh-word in situ — "in its place." Notice what didn't happen: no fronting, no inversion, no helper word. The sentence frame is identical to the declarative Você comprou um carro ("You bought a car"); only the object slot has been swapped for a stressed question word.
This is the single biggest difference from English. English can do in-situ echoes ("You did what?"), but English speakers often default to a full fronted question even as an echo ("What did you say?"). In Brazilian Portuguese, the in-situ version is the natural, idiomatic choice for reacting to something just said.
"O quê" vs "que" — the stressed form
There's an orthographic detail that trips learners up. When que sits at the end of a phrase or stands alone — exactly where echo questions put it — it takes a circumflex and becomes o quê or just quê:
Ele falou o quê?
He said WHAT?
Você fez isso por quê?
You did that — why? (for what reason?)
Compare the fronted, unstressed version, written o que with no accent: O que ele falou? The accent on quê is not optional decoration — it marks the stressed, sentence-final form. Writing Ele falou o que? for an echo is an orthographic error.
Quê?! Você não vai vir mais?
What?! You're not coming anymore?
The short reactions: Quê?, Quem?, Como assim?
Often you echo nothing but the question word itself. These are the fastest, most reflexive reactions in the language, and they're worth memorizing as fixed expressions.
| Reaction | Use | Register |
|---|---|---|
| O quê? / Quê? | "What?" — didn't hear, or disbelief | (informal) |
| Como? | "Sorry?" — polite "I didn't catch that" | (neutral) |
| Quem? | "Who?" — which person? | (neutral) |
| Onde? | "Where?" | (neutral) |
| Como assim? | "What do you mean?" — asking for clarification, mild surprise | (neutral) |
| O quê?! | strong disbelief | (informal) |
— A festa foi cancelada. — Quê?! Por quê?
— The party was canceled. — What?! Why?
— Ela vai se casar. — Com quem?
— She's getting married. — To whom?
Como assim? deserves special attention. It doesn't ask you to repeat — it asks you to explain. You use it when you heard the words but the meaning, logic, or implication confuses you.
— A gente terminou. — Como assim, vocês terminaram? Ontem estava tudo bem!
— We broke up. — What do you mean, you broke up? Yesterday everything was fine!
Echoing the whole thing for emphasis
You can echo a longer chunk of the sentence, repeating the part you want confirmed and dropping the stressed question word into the spot you're questioning. This is the structure that most clearly shows the in-situ pattern.
Você foi onde no fim de semana?
You went WHERE on the weekend?
Vocês gastaram quanto na viagem?
You spent HOW MUCH on the trip?
Ela disse que chega que horas?
She said she's arriving at WHAT time?
In each case the question word lands precisely where the original information was, never at the front. Compare the neutral fronted questions — Onde você foi...?, Quanto vocês gastaram...?, Que horas...? — and you can hear the difference: the fronted version is a first-time question; the in-situ version is a reaction to something already said.
Intonation does the heavy lifting
Because the word order is identical to a statement, intonation is what signals the question. Brazilian Portuguese gives the in-situ question word a sharp pitch rise (for "I didn't hear you") or a sharp, sometimes falling-then-rising contour (for "I can't believe it"). In writing, this is captured with the question mark and often a combined "?!" for the incredulous reading.
Custou mil reais?! Tá de brincadeira!
It cost a THOUSAND reais?! You're kidding!
Because the spoken signal is everything, learners who flatten the stress sound like they're making a statement, not echoing a question. Exaggerate the rise more than feels natural at first.
Common Mistakes
❌ Você comprou que?
Incorrect — sentence-final stressed 'que' needs the circumflex.
✅ Você comprou o quê?
You bought WHAT?
❌ O que você foi? (as an echo of 'I went to the beach')
Incorrect — fronting the word turns it into a fresh question and changes the meaning ('What were you?').
✅ Você foi onde?
You went WHERE? — keep the word in place.
❌ Que você disse? (meaning 'Sorry, what?' to a stranger)
Too blunt and structurally odd as a polite reprise.
✅ Como? / Desculpa, como?
Sorry? / Sorry, what was that? — the polite reprise.
❌ Como assim você comprou o quê? (mixing two reactions awkwardly)
Don't stack 'como assim' with an in-situ 'o quê' — pick one.
✅ Você comprou o quê?! / Como assim, você comprou?
Pick the disbelief echo OR the clarification request.
❌ Ele falou o que? (flat statement intonation)
Without the rising stress it reads as a relative clause, not an echo.
✅ Ele falou o QUÊ?!
He said WHAT?! — let the pitch jump.
Key Takeaways
- The defining feature of the echo question is the wh-word staying in situ — in the slot where the answer goes — never fronted.
- Sentence-final stressed que is written quê (with the circumflex): o quê?, por quê?
- Como? is the polite reprise; O quê? is informal and can signal disbelief; Como assim? asks for an explanation, not a repetition.
- Word order matches a statement, so intonation (a sharp rise) is what marks it as a question — exaggerate it.
- This contrasts directly with normal wh-questions, where the word is fronted (O que você comprou?). Echo questions are reactions, not fresh questions.
