Você quer outra coisa?

Because você uses the third-person singular verb form in Portuguese, even though it means you.

So:

• você quer = you want
• ele quer = he wants
• ela quer = she wants

This is one of the first things English speakers notice, because in English you does not change the verb much, but in Portuguese it does.

If you used tu, then in more standard grammar you would say:

• tu queres

But in most of Brazil, você quer is much more common.

Você means you.

In Brazil, it is the most common way to address one person in many situations. It can be neutral, everyday, and very natural.

A few important notes:

• você = singular you
• vocês = plural you all / you guys
• It normally takes third-person verb forms

Depending on the region, people may also use tu, but você is extremely common across Brazil.

Literally, outra coisa means another thing.

Word by word:

• outra = other / another
• coisa = thing

So the sentence literally reads:

• Você quer outra coisa? = Do you want another thing?

In natural English, though, it often means something like:

• Do you want something else?
• Would you like anything else?

Because coisa is a feminine noun.

In Portuguese, adjectives and words like outro/outra usually agree with the noun they describe.

So:

• outra coisa = another thing
  (coisa is feminine)
• outro livro = another book
  (livro is masculine)

This is grammatical agreement, and it is very important in Portuguese.

Portuguese often does not need an article in this kind of expression.

So outra coisa is perfectly natural and probably the most common wording here.

You may also hear:

• uma outra coisa

But that can sound a little more specific, emphatic, or stylistically different depending on context. In everyday speech, outra coisa is very normal.

So for a learner, the safest choice is:

• Você quer outra coisa?

It is natural, but the nuance can depend on context.

Você quer outra coisa? often sounds like:

• Do you want something different?
• Do you want another thing?

In a store, restaurant, or service situation, Brazilians very often say:

• Quer mais alguma coisa? = Do you want anything else?
• Mais alguma coisa? = Anything else?

So:

• outra coisa can suggest another/different item
• mais alguma coisa more naturally suggests anything else / something more

Both are correct, but mais alguma coisa is especially common in customer-service situations.

Yes. That is very common in Brazilian Portuguese.

Portuguese often drops subject pronouns when the meaning is clear from context. So both of these work:

• Você quer outra coisa?
• Quer outra coisa?

In Brazil, people often keep você for clarity or emphasis, but omitting it is completely natural in conversation.

Yes. Coisa is a very general word, much like thing in English.

It is used all the time in everyday Portuguese, especially when:

• the exact object is obvious from context
• the speaker wants to be general
• the speaker is asking broadly

So in this sentence, coisa is not strange at all. It is a normal, flexible word.

A rough Brazilian Portuguese pronunciation is:

• vo-SEH kehr OH-tra KOY-zah?

A few tips:

• você has stress on the last syllable: vo-SEH
• quer sounds roughly like kehr
• outra begins with a diphthong, roughly OH-tra
• coisa sounds roughly like KOY-zah

Depending on the region, pronunciation can vary a bit, especially the final sounds and the r in quer.

No. Portuguese usually does not change the word order the way English does.

In English, you say:

• You want another thing.
• Do you want another thing?

But in Portuguese, the statement and the question can have the same word order:

• Você quer outra coisa. = You want another thing.
• Você quer outra coisa? = Do you want another thing?

The question is shown mainly by:

• intonation
• context
• question marks in writing

It is generally neutral to informal, and very normal in everyday Brazilian Portuguese.

Because it uses você, it is not highly formal. In very formal situations, someone might use:

• O senhor quer outra coisa? = speaking politely to a man
• A senhora quer outra coisa? = speaking politely to a woman

But in most everyday situations in Brazil, Você quer outra coisa? sounds completely normal.
