Forming Interrogative Sentences in Portuguese
Perguntas, or questions, are an essential component of Portuguese grammar. To effectively communicate and gather information, one must master the formation of interrogative sentences. These sentences often start with question words, such as “quem” (who), “o que” (what), “quando” (when), “onde” (where), “por que” (why), and “como” (how).

Important Question Words in Portuguese

O que (What)
“O que” is used to inquire about objects, events, or actions in general. For example:
– O que você quer fazer? (“What do you want to do?”)

Quem (Who)
“Quem” is utilized to ask about people or entities. For instance:
– Quem está batendo na porta? (“Who is knocking on the door?”)

Quando (When)
“Quando” is employed to inquire about the timing of events. Examples include:
– Quando é a reunião? (“When is the meeting?”)

Onde (Where)
When asking about locations, “onde” is the appropriate question word. An example:
– Onde fica a biblioteca? (“Where is the library?”)

Por que (Why)
To ask for the reason behind an action or event, use “por que.” For instance:
– Por que você está atrasado? (“Why are you late?”)

Como (How)
“Como” is employed to inquire about the manner in which something occurs. For example:
– Como você resolveu esse problema? (“How did you solve this problem?”)

Rules for Asking Yes/No Questions in Portuguese

Using Correct Question Intonation
In verbal communication, yes/no questions are formed using a rising intonation at the end of the statement. For example:
– Você fala inglês? (“Do you speak English?”)

Inverting Verb-Subject Order
In written communication, the verb-subject order is inverted to form a question. For instance:
– Sabe você escrever em português? (“Do you know how to write in Portuguese?”)

Utilizing the Word “Será”
Another way to form yes/no questions is by using the word “será,” meaning “could it be.” For example:
– Será que vai chover? (“Could it be that it’s going to rain?”)

Indirect Questions in Portuguese

When forming an indirect question, the main clause remains unchanged, but the subordinate clause uses the question word. An example:
– Eu queria saber como você aprendeu português. (“I wanted to know how you learned Portuguese.”)

Tag Questions in Portuguese Grammar

To elicit confirmation or agreement, tag questions can be employed using phrases like “não é?,” “né?,” or “certo?.” Examples include:
– Ela é brasileira, não é? (“She’s Brazilian, isn’t she?”)
– Vamos à praia amanhã, certo? (“We’re going to the beach tomorrow, right?”)
