Eu quero partir agora.

In Brazilian Portuguese, you can often omit the subject pronoun when it is clear from the verb or context.

So both are possible:

• Eu quero partir agora.
• Quero partir agora.

Both mean the same thing here.

That said, eu is often included for:

• emphasis: I want to leave now.
• clarity
• natural spoken rhythm

In everyday Brazilian Portuguese, speakers use subject pronouns more often than in some other varieties of Portuguese, so eu quero sounds very normal.

Because after querer when it means to want to do something, Portuguese normally uses the infinitive directly:

• quero partir = want to leave
• quero comer = want to eat
• quero dormir = want to sleep

There is no extra word like to, de, or para in this structure.

So English says:

• I want to leave

Portuguese says:

• Eu quero partir

Partir is in the infinitive form, the basic dictionary form of the verb.

In Eu quero partir agora:

• quero = I want
• partir = to leave / to depart

This is a very common pattern in Portuguese:

• Eu preciso estudar.
• Ela quer sair.
• Nós vamos viajar.

A conjugated verb is followed by an infinitive.

It is correct, but in Brazilian Portuguese it can sound a bit formal, literary, or dramatic, depending on context.

In everyday speech, Brazilians more often say:

• sair = to leave / to go out
• ir embora = to go away / leave

So in casual conversation, these are often more natural:

• Eu quero sair agora.
• Eu quero ir embora agora.

Partir is still understood, and you may hear it in:

• more formal speech
• writing
• songs
• emotional or poetic contexts
• transportation/travel contexts, like a train or bus departing

They can all relate to leaving, but they are not always used in exactly the same way.

• partir = to depart

  • often more formal or literary
  • can suggest setting off on a journey

• sair = to leave / go out

  • very common in everyday speech
  • can mean leaving a place in general

• ir embora = to go away / leave

  • extremely common in Brazil
  • often used when someone wants to go away from where they are now

Examples:

• Vou sair de casa agora. = I’m leaving the house now.
• Quero ir embora. = I want to go home / I want to leave.
• O trem vai partir às 8. = The train will depart at 8.

So Eu quero partir agora is correct, but Eu quero ir embora agora may sound more natural in many daily situations.

A simple approximate pronunciation for an English speaker is:

eh-ooh KEH-roh par-CHEER ah-GOH-rah

A few notes:

• Eu sounds roughly like eh-ooh said quickly together.
• quero has stress on que: KEH-ro
• In much of Brazil, tir in partir sounds like cheer or teer, depending on accent. A common Brazilian pronunciation is close to par-CHEER.
• agora usually has stress on go: a-GO-ra

The sentence stress usually falls naturally on:

• quero
• partir
• agora

Because querer is the infinitive, and quero is the first-person singular present tense form.

The verb is querer = to want

Present tense:

• eu quero = I want
• você quer = you want
• ele/ela quer = he/she wants
• nós queremos = we want
• vocês querem = you all want
• eles/elas querem = they want

So:

• Eu quero partir agora = I want to leave now

Not:

• Eu querer partir agora — this is incorrect in standard Portuguese.

Yes. Agora usually means now, and it can move around, although some positions sound more natural than others.

Common possibilities:

• Eu quero partir agora.
• Agora eu quero partir.
• Eu agora quero partir. (possible, but less common and often more marked)

The most neutral version is:

• Eu quero partir agora.

If you put agora at the beginning, it can add emphasis, like:

• Now I want to leave.

Yes, especially because of partir.

While the basic meaning is simple, partir can sound:

• more serious
• more dramatic
• more poetic

So depending on tone or context, Eu quero partir agora might feel like:

• I want to depart now
• I want to go now
• even something emotionally intense in a literary context

In ordinary daily conversation, if you just mean I want to leave now, many Brazilians would more naturally say:

• Eu quero sair agora.
• Eu quero ir embora agora.

Yes. Partir can also mean to split, to break, or to divide, depending on context.

For example:

• partir o pão = to break/split the bread
• partir o coração = to break the heart

But in Eu quero partir agora, the meaning is clearly to leave / depart.

This is very common in Portuguese: one verb can have multiple related meanings, and the context tells you which one is intended.

They might, but it is not the most typical casual phrasing.

In everyday Brazilian Portuguese, these are often more natural:

• Eu quero ir embora agora.
• Quero ir embora agora.
• Eu quero sair agora.

Your original sentence is still:

• grammatically correct
• understandable
• natural in some contexts

It just sounds a bit more formal, stylized, or deliberate than the most common everyday alternatives.
