How to form simple questions
In Portuguese you can often form a question by using a question word plus a normal sentence order. The tone and punctuation show it is a question, though sometimes you invert verb and subject for a more formal question.
Basic pattern: Question word + verb + subject (if needed)
Example: Onde você mora? Where do you live? — question word onde, verb mora, subject você.
In informal speech you can drop the subject: Onde mora? is possible with a polite tone when context is clear.
Yes/no questions: Use intonation or add question words like né? or inversion
Example: Você estuda espanhol? Do you study Spanish? Intonation makes it a question. More formal: Estuda você espanhol?
Short functional phrases with question words
These compact phrases are seen on signs, menus, schedules, and in basic service interactions.
Onde é a saída?
Where is the exit?
Que horas?
What time?
Qual número?
Which number?
Quanto tempo?

Quem atende?

Practical mini-dialogues for beginners

Cliente: O que você recomenda? What do you recommend?
Atendente: Recomendo o pão de queijo. I recommend the cheese bread.
Bus stop
Passageiro: Que ônibus vai para o centro? Which bus goes to downtown?
Motorista: O número 5. Number 5.

Common beginner mistakes and how to avoid them
Beginners often transfer English word order directly into Portuguese or mix up por que and porque. Here are frequent errors and simple fixes.
Mistake: Writing porquê, porque, por que interchangeably
Tip: Use por que to ask why in direct questions. Use porque as an answer meaning because. Use porquê as a noun meaning reason (less common) and por quê at the end of a sentence before punctuation.
Examples
Por que você estuda? Why do you study?
Porque eu gosto. Because I like it.
Mistake: Overusing literal translations for how and what
Tip: For how much use quanto, but match gender and number with the noun: quanto (masculine singular), quanta (feminine singular), quantos (masculine plural), quantas (feminine plural).
Examples
Quanto custa? How much does it cost?
Quantas pessoas? How many people?
Mistake: Forgetting to use Onde for places instead of Em onde
Tip: Use onde rather than em onde in most spoken contexts. Em onde can appear in written or formal constructions, but beginners should stick to onde.
Example
Onde você mora? not Em onde você mora?
Simple practice activities
These beginner-friendly activities help memorize question words and build confidence in real contexts.

3. Build mini-dialogues
