How to use “Quem” in Portuguese questions for beginners

Introduction

Learning how to ask about people in Brazilian Portuguese starts with one small, essential word: Quem. This article explains when and how to use Quem in questions, with clear examples, common phrases, beginner tips, and typical mistakes to avoid.

What does Quem mean?

Quem means who in English and is used to ask about people. It is the go-to question word when you want to identify a person, ask who performed an action, or request the name of someone.

Basic sentence position

In Brazilian Portuguese questions, Quem usually appears at the beginning of the sentence, followed by a verb or auxiliary verb. Simple pattern: Quem + verb + rest of sentence.

Examples:

Quem é você?

Quem falou com ela?

Quem vai ao mercado?

Simple question structures with Quem

Here are the most common structures beginners will use with Quem.

1. Asking for identity or name

Structure: Quem + é + subject

Examples:

Quem é você?
Explanation: Who are you?

Quem é ele?
Explanation: Who is he?

Quem é o motorista?
Explanation: Who is the driver?

2. Asking who did something (subject questions)

Structure: Quem + verb

Examples:

Quem fez isso?
Explanation: Who did this?

Quem comprou pão?
Explanation: Who bought bread?

Quem chamou a Maria?
Explanation: Who called Maria?

3. Asking who something belongs to or who is responsible

Structure: Quem + é + de + person/thing

Examples:

De quem é este celular?
Explanation: Whose phone is this?

De quem é a mochila?
Explanation: Whose backpack is this?

4. Asking for a subject with prepositions

Quem can appear after prepositions when asking about the person related to an action or object. Remember that the preposition often stays before the rest of the sentence.

Examples:

Com quem você vai?
Explanation: With whom are you going?/Who are you going with?

Para quem é este presente?
Explanation: For whom is this gift?/Who is this gift for?

Using pronouns with Quem

When a question expects an object pronoun answer, pay attention to pronoun placement. In spoken Brazilian Portuguese, subject pronouns may be omitted because the verb conjugation shows the subject.

Examples:

Quem te viu ontem?
Explanation: Who saw you yesterday? (te = you)

Quem nos convidou?
Explanation: Who invited us? (nos = us)

Formality and polite questions

To be polite, use the conditional or add por favor. The word Quem remains the same.

Examples:

Com quem eu posso falar, por favor?
Explanation: With whom can I speak, please?

Quem poderia me ajudar?
Explanation: Who could help me?

Answers to Quem questions are usually a name, a pronoun, or a noun phrase. Learn simple reply formulas.

Examples:

Foi o João.
Explanation: It was João.

Ela.
Explanation: She.

O gerente.

Follow-up questions often use more context words:
