Nós vamos nos encontrar na praça na sexta-feira.

In Brazilian Portuguese, ir + infinitive is a very common way to talk about the future.

So:

Nós vamos nos encontrar = We are going to meet

A more formal or more literary version would be:

Nós nos encontraremos

Both are correct, but vamos + infinitive is much more common in everyday speech.

The verb encontrar means to find or to meet.

In this sentence, nos shows that the action is reciprocal: we will meet each other.

So:

• encontrar = to meet / to find
• nos encontrar = to meet each other

English does not always mark this explicitly, but Portuguese often does.

Because the subject is nós = we.

The reflexive/reciprocal pronoun has to match the subject:

• eu → me
• você / ele / ela → se
• nós → nos
• vocês / eles / elas → se

So:

• Nós vamos nos encontrar = We are going to meet
• Eles vão se encontrar = They are going to meet

In Brazilian Portuguese, when you have ir + infinitive, the pronoun often comes before the infinitive:

vamos nos encontrar

This is very natural in Brazil.

You may also see forms like vamos encontrar-nos, especially in more formal writing or in European Portuguese, but in Brazilian Portuguese, vamos nos encontrar is the normal everyday choice.

Yes, you can leave out nós.

Portuguese often drops subject pronouns when the verb already makes the subject clear.

So both are correct:

• Nós vamos nos encontrar na praça na sexta-feira
• Vamos nos encontrar na praça na sexta-feira

Because vamos clearly means we go / we are going, the subject is already understood.

Na is a contraction of em + a.

• em = in / at / on
• a = the

So:

• a praça = the square / the plaza
• em a praça → na praça

This means in the square or, more naturally in English, at the square.

For the same reason: na = em + a.

• a sexta-feira = Friday
• em a sexta-feira → na sexta-feira

In Portuguese, days of the week are often used with the article, especially in Brazilian Portuguese.

So na sexta-feira means on Friday.

This is just a normal feature of Portuguese.

English says on Friday with no article, but Portuguese commonly says:

• na sexta-feira = on Friday
• na segunda-feira = on Monday

The article is part of how Portuguese normally builds these expressions. It may feel unusual to an English speaker, but it is very natural in Portuguese.

Usually, praça refers to a public square, plaza, or open public space in a town or city.

Depending on context, English might translate it as:

• square
• plaza
• town square

So na praça is often best understood as at the square or in the plaza.

Yes, absolutely. That is extremely common in spoken Brazilian Portuguese.

• nós vamos nos encontrar = more standard / neutral
• a gente vai se encontrar = very common in everyday speech

Even though a gente literally looks singular, it usually means we, and the verb stays in the third person singular:

• A gente vai
• not A gente vamos

Also notice the pronoun changes:

• nós ... nos encontrar
• a gente ... se encontrar

Yes. Portuguese word order is flexible.

These are all natural:

• Nós vamos nos encontrar na praça na sexta-feira.
• Na sexta-feira, nós vamos nos encontrar na praça.
• Nós vamos nos encontrar na sexta-feira na praça.

The original order is very normal, but moving na sexta-feira to the beginning can put more emphasis on the time.

Not always.

Portuguese can use encontrar in different ways:

• Encontrei meu amigo na rua. = I met/found my friend on the street.
• Nós vamos nos encontrar. = We are going to meet each other.

So when the meaning is reciprocal, Portuguese often uses the pronoun:

• nos encontrar
• se encontrar

That is why it appears in this sentence.

Yes.

Nós iremos nos encontrar na praça na sexta-feira is grammatically correct and means the same thing.

But in everyday Brazilian Portuguese, nós vamos nos encontrar sounds more natural and more common than nós iremos nos encontrar.

So a learner should definitely recognize iremos, but use vamos + infinitive confidently in conversation.
