Você quer jantar conosco?

In Brazilian Portuguese, você means you, but it takes third-person singular verb forms.

So:

• eu quero = I want
• você quer = you want
• ele/ela quer = he/she wants

This happens because você historically comes from a longer expression that was treated grammatically as third person. So even though it means you, the verb matches he/she grammar.

That is why Você quer... is correct, not Você queres....

In Portuguese, yes/no questions usually keep the same word order as statements. The difference is shown mainly by:

• intonation in speech
• a question mark in writing

So:

• Você quer jantar conosco. = statement
• Você quer jantar conosco? = question

Unlike English, Portuguese does not usually need a helping verb like do or inversion like Do you want....

Here, jantar is a verb in the infinitive form.

After querer (to want), Portuguese often uses an infinitive:

• quer comer = wants to eat
• quer sair = wants to go out
• quer jantar = wants to have dinner / wants to dine

So in this sentence, jantar means to have dinner, not dinner as a noun.

Yes. Jantar can be both:

• a verb: to have dinner
• a noun: dinner

Examples:

• Vamos jantar. = Let’s have dinner.
• O jantar está pronto. = Dinner is ready.

In Você quer jantar conosco?, it is clearly a verb because it follows quer.

Comer means to eat in a general sense.
Jantar specifically means to have dinner.

Compare:

• Você quer comer conosco? = Do you want to eat with us?
• Você quer jantar conosco? = Do you want to have dinner with us?

So jantar is more specific and sounds natural when talking about the evening meal.

Conosco means with us.

Portuguese has special forms for com + pronoun:

• comigo = with me
• contigo = with you
• consigo = with you / him / her / themself, depending on context
• conosco = with us
• convosco = with you all (rare in Brazil)

So conosco is the standard form for with us.

In Brazil, people also very often say:

• com a gente = with us

That is extremely common in everyday speech.

Com nós is not the usual standard form by itself. It can appear in certain cases, especially when something is added for emphasis, such as com nós dois.

Yes, conosco is correct and natural, but in everyday Brazilian Portuguese, many people would more commonly say:

Você quer jantar com a gente?

That version is very common and sounds very natural in casual conversation.

So:

• conosco = correct, natural, slightly more formal or polished
• com a gente = very common in daily speech

In Brazilian Portuguese, você is the normal everyday word for you in most situations. It is neither especially formal nor especially rude.

Roughly speaking:

• você = standard everyday you
• o senhor / a senhora = more formal or respectful
• tu = used in some regions, with regional differences in verb agreement

So if you wanted to make the sentence more formal, you could say:

• O senhor quer jantar conosco?
• A senhora quer jantar conosco?

Yes, in regions where tu is used, you could hear versions like:

• Tu quer jantar conosco? — common in some Brazilian varieties
• Tu queres jantar conosco? — grammatically traditional form

Brazilian Portuguese varies a lot by region. In many places, people use tu but still use the third-person verb form in everyday speech, so tu quer is very common regionally.

For a learner of general Brazilian Portuguese, você quer is the safest default.

A simple approximate pronunciation is:

vo-SEH kehr zhan-TAR ko-NOS-ko?

A few notes:

• você sounds roughly like vo-SEH
• quer is roughly kehr
• j in jantar sounds like the s in measure or the zh sound
• the final r in jantar is often softer in Brazilian Portuguese, especially in casual speech
• conosco is roughly ko-NOS-ko

In natural Brazilian speech, the whole sentence flows together smoothly.

Yes. Portuguese often drops subject pronouns when the meaning is clear from context.

So both are possible:

• Você quer jantar conosco?
• Quer jantar conosco?

In conversation, Quer jantar conosco? can sound very natural, especially when you are speaking directly to someone and it is obvious who you mean.

Keeping você can add clarity or emphasis.

Yes. The second one is softer and more polite.

• Você quer jantar conosco? = direct, normal, natural
• Você gostaria de jantar conosco? = more polite, more tentative, a bit more formal

Both are correct. The first is common in everyday speech; the second sounds more courteous or careful.

Because Portuguese does not use a separate word like English to before the infinitive in this structure.

English:

• You want to eat
• You want to have dinner

Portuguese:

• Você quer comer
• Você quer jantar

The infinitive appears directly after quer. That is normal Portuguese grammar.
