Eu quero revisar o texto antes da reunião.

Yes, you often can leave it out.

Portuguese is a pro-drop language, which means the subject pronoun is often omitted when the verb already makes the subject clear. So:

• Eu quero revisar o texto antes da reunião.
• Quero revisar o texto antes da reunião.

Both are natural.

Including Eu can add:

• emphasis
• contrast
• clarity

For example, Eu quero revisar o texto, mas ele quer enviar agora emphasizes I.

After querer when you mean to want to do something, the next verb stays in the infinitive.

So:

• quero revisar = I want to review
• quero ler = I want to read
• quero sair = I want to leave

You do not conjugate the second verb here:

• correct: quero revisar
• incorrect: quero reviso

This is the same pattern as English want to + verb.

Quero is the first-person singular present tense of querer:

• eu quero = I want

A few forms of querer in the present:

• eu quero
• você quer
• ele/ela quer
• nós queremos
• vocês querem
• eles/elas querem

So in this sentence, quero matches Eu.

Here, revisar means to review, to revise, or to check over a text.

For example, revisar o texto usually suggests:

• checking for mistakes
• improving wording
• proofreading
• making corrections

Rever can also mean to review, but it is broader and often means:

• to see again
• to reconsider
• to rewatch
• to review in a more general sense

So for editing or checking a document, revisar o texto is very natural.

Portuguese uses definite articles much more often than English.

So o texto literally means the text, and in many contexts Portuguese prefers the article where English might not stress it as much.

Examples:

• Li o relatório. = I read the report.
• Preciso enviar o e-mail. = I need to send the email.
• Vou revisar o texto. = I’m going to review the text.

Leaving out the article here would usually sound less natural unless the structure changed.

Because de + a contracts into da in Portuguese.

So:

• de + a = da
• de + o = do
• em + a = na
• em + o = no

In this sentence:

• antes de a reunião becomes antes da reunião

This contraction is required in normal Portuguese.

Antes normally needs the preposition de when it is followed by something.

So:

• antes da reunião = before the meeting
• antes do almoço = before lunch
• antes de sair = before leaving

You can think of the full structure as:

• antes de + noun
• antes de + infinitive

Examples:

• antes da aula
• antes de estudar

Antes da reunião means before the meeting — a specific meeting, or one understood from context.

Antes de reunião is not the normal phrasing in this sentence.

If you are talking about a particular meeting, Portuguese wants the article:

• antes da reunião

Without the article, it would usually sound incomplete or unnatural here.

Mostly yes. The structure is very straightforward:

• Eu = subject
• quero = main conjugated verb
• revisar = infinitive
• o texto = object
• antes da reunião = time expression

So the pattern is:

Subject + want + infinitive + object + time phrase

That is very close to English: I want to review the text before the meeting.

Yes, absolutely. That is very common and natural in Brazil.

In everyday speech, Brazilians often omit Eu when the meaning is clear:

• Quero revisar o texto antes da reunião.

If you include Eu, it may sound:

• slightly more explicit
• more emphatic
• useful for contrast

Both versions are correct.

The written sentence is already natural. In speech, a Brazilian might say:

• Quero revisar o texto antes da reunião.

Depending on context, people might also choose:

• Quero dar uma revisada no texto antes da reunião.
• Quero rever o texto antes da reunião.

These alternatives are a bit more conversational, but the original sentence is perfectly normal and clear.

Reunião is roughly pronounced like heh-oo-nee-OWN in Brazilian Portuguese, though English spelling cannot capture it exactly.

A few helpful points:

• the r at the beginning of a word in Brazilian Portuguese often sounds like an h sound
• ão is a nasal ending, very common in Portuguese
• the stress is on the last syllable: reu-ni-ÃO

So the hardest part for many English speakers is the nasal ão sound.

Not exactly. They are related, but not the same.

• revisar o texto = review/check the text
• corrigir o texto = correct the text

Revisar is broader: you look over the text for possible problems. Corrigir focuses more on fixing errors.

So if your intention is look over the text before the meeting, revisar is the better choice.

It is neutral. It works well in:

• everyday speech
• work situations
• email
• professional conversation

Nothing in it is especially formal or especially casual. It is a standard, natural sentence in Brazilian Portuguese.

Texto usually refers to written content, but depending on context it can mean:

• a text
• a draft
• written copy
• the wording/content of a document

If you specifically mean a report, document, or file, Portuguese might use a more specific word:

• documento = document
• relatório = report
• rascunho = draft

But o texto is very natural if the focus is on the written content itself.
