Eu vou embora agora.

Yes. In Brazilian Portuguese, the subject pronoun is often optional because the verb already shows the person.

• Eu vou embora agora = I’m leaving now
• Vou embora agora = same meaning

Including eu can add emphasis, clarity, or contrast, for example:

• Eu vou embora agora, mas ele fica.
  I’m leaving now, but he’s staying.

In everyday speech, Vou embora agora is very common.

Vou is the 1st person singular present tense of ir (to go).

So:

• eu vou = I go / I am going

In this sentence, it works naturally as I’m leaving or I’m going now. Portuguese often uses the simple present for something happening right now or in the near future.

Because ir embora is a very common fixed expression meaning to go away / to leave.

So:

• ir = to go
• embora = part of the expression
• ir embora = to leave

Portuguese does also have sair, which can mean to leave / to go out, but ir embora is extremely common when you mean leaving a place and going away.

For example:

• Vou embora. = I’m leaving.
• Vou sair. = I’m going out / I’m leaving
  depending on context

Yes, but it depends on context.

In vou embora, embora is part of the expression ir embora = to leave.

But embora can also appear as a conjunction meaning something like although / even though in more formal Portuguese:

• Embora esteja cansado, vou trabalhar.
  Although I’m tired, I’m going to work.

So learners often get confused because embora has more than one use. In your sentence, it is definitely the leaving expression.

Yes, agora means now, and its position is flexible.

All of these are possible:

• Eu vou embora agora.
• Agora eu vou embora.
• Eu agora vou embora.

The most natural version in everyday speech is often:

• Eu vou embora agora.

Putting agora first can give it a little more emphasis:

• Agora eu vou embora.
  = Now I’m leaving.

They are very close, but there is a slight difference in feel.

• Eu vou embora agora = I’m leaving now
• Estou indo embora agora = I’m on my way out now / I’m in the process of leaving now

Vou embora is very common and natural. Estou indo embora emphasizes the action as ongoing.

In many situations, either one works.

These are related, but not identical.

• Eu vou embora agora = I’m leaving now
  Focus: going away from where you are

• Eu saio agora = I leave now / I’m heading out now
  This can sound a little more literal or situational

• Eu vou sair agora = I’m going to go out now / I’m about to leave now
  This can suggest going out, stepping out, or leaving soon

In many daily situations, vou embora agora is the most idiomatic way to say I’m leaving now.

Yes. It can be used in many situations where you are announcing that you are leaving.

For example:

• leaving someone’s house
• leaving work
• ending a visit
• ending an in-person conversation

For a phone call or online conversation, people may also use other expressions depending on the situation, such as:

• Tenho que ir agora. = I have to go now.
• Vou desligar. = I’m going to hang up.
• Vou sair. = I’m heading out.

But vou embora agora is absolutely normal when you are physically leaving a place.

It is neutral and very natural. It works well in everyday Brazilian Portuguese.

It is not especially formal, but it is not rude either. Tone and context matter more than the words themselves.

You can make it softer or more polite by adding something like:

• Eu vou embora agora, tá?
• Acho que vou embora agora.
• Vou indo, pessoal.

These can sound friendlier depending on the situation.

In standard Brazilian Portuguese, no. The normal expression is simply:

• Eu vou embora agora

You may occasionally see older or more literary forms like vou-me embora, especially in European Portuguese or in songs, poetry, or fixed expressions, but that is not the normal everyday Brazilian pattern.

So for modern Brazilian Portuguese, stick with:

• vou embora

A rough breakdown is:

• Eu = I
• vou = go / am going
• embora = part of go away / leave
• agora = now

So literally it is something like:

• I go away now

But in natural English, that becomes:

• I’m leaving now

In careful speech, roughly:

• eu sounds something like eh-oo said quickly together
• vou sounds roughly like voh with a glide at the end
• embora sounds like em-BO-ra
• agora sounds like a-GO-ra

In natural Brazilian speech, words connect smoothly, so it may sound more like one flowing phrase than four separate words.

A few useful pronunciation notes:

• vou and embora may connect smoothly
• the r in agora depends on accent, but in most Brazilian accents this internal r is a light tapped sound
• stress falls on:
  • vou
  • bo in embora
  • go in agora

Dropping it is often more natural.

• Vou embora agora. sounds very normal.
• Eu vou embora agora. also sounds normal, but with a bit more explicitness or emphasis.

Brazilian Portuguese uses subject pronouns more often than European Portuguese, but they are still frequently omitted when the meaning is clear.

Very simply:

Question

• Você vai embora agora? = Are you leaving now?
• Você vai embora agora mesmo? = Are you leaving right now?

Negative

• Eu não vou embora agora. = I’m not leaving now.
• Eu não vou embora ainda. = I’m not leaving yet.

The negative marker não goes before the verb:

• não vou

It is used in both, and the basic meaning is the same.

• Eu vou embora agora is understandable everywhere Portuguese is spoken.

The biggest differences would be pronunciation and some style preferences, not the grammar of this sentence itself.

In Brazil, ir embora is extremely common in everyday speech.
