Eu vou verificar a tradução.

Yes. In Brazilian Portuguese, subject pronouns are often optional because the verb form already shows the subject.

• Eu vou verificar a tradução. = I am going to check the translation.
• Vou verificar a tradução. = Am going to check the translation.

Including eu can:

• add emphasis,
• make the subject extra clear,
• create contrast, as in Eu vou verificar, mas ele não.

In everyday speech, leaving eu out is very common.

This is a very common Portuguese future construction:

• vou = I go / I am going
• verificar = to check / to verify

Together, vou verificar literally means something like I am going to check.

This is parallel to English be going to + verb:

• I am going to check
• Eu vou verificar

Portuguese uses this structure a lot in everyday speech instead of the simple future form.

Yes. Verificarei a tradução is the simple future form and also means I will check the translation.

Compare:

• Eu vou verificar a tradução. → very common in spoken Brazilian Portuguese
• Verificarei a tradução. → correct, but often sounds more formal, written, or less conversational

In Brazil, ir + infinitive is usually the more natural everyday choice.

Both can mean to check, but there is a slight difference in feel.

• verificar is a more standard, neutral, and often slightly more formal verb
• checar is very common too, especially in modern speech, and feels a bit more informal or influenced by English

So:

• Vou verificar a tradução sounds very natural and standard
• Vou checar a tradução also sounds natural in many contexts

If you want the safest all-purpose choice, verificar is excellent.

Portuguese often uses definite articles more than English does.

• a tradução = the translation

In this sentence, it sounds like a specific translation is being checked, so a is natural.

Saying just Vou verificar tradução would usually sound incomplete or unnatural here. You would normally want:

• Vou verificar a tradução.

The normal word order is:

• Eu = subject
• vou verificar = verb phrase
• a tradução = object

So:

• Eu vou verificar a tradução.

This is the most neutral and natural order.

You can move things around in Portuguese for emphasis, but that is less basic and often more context-dependent. For a learner, the standard order is the best one to use.

In Brazilian Portuguese, vou is pronounced roughly like voh with a slight w glide at the end, something close to voh-oo said quickly.

A rough English approximation is:

• voh or vohw

Important points:

• the ou here does not sound like English ow in cow
• it is more like a closed o sound with a light glide

So vou verificar sounds roughly like:

• voh veh-ree-fee-KAR

That is only an approximation, but it helps.

In Brazilian Portuguese, verificar is roughly:

• veh-ree-fee-KAR

Stress is on the last syllable:

• veri-fi-CAR

A few pronunciation notes:

• r at the beginning of a word or as rr is usually a stronger sound in Brazilian Portuguese, but here the r in verificar is inside the word
• the final r in Brazil is often pronounced like an h-like sound, depending on the region

So the end may sound closer to:

• kah or
• kar/h

depending on accent.

Yes, tradução is feminine, which is why it uses a:

• a tradução

Many nouns ending in -ção are feminine in Portuguese:

• a tradução = the translation
• a informação = the information
• a explicação = the explanation

This is a very useful pattern to remember.

Yes. Verificar can mean both check and verify, depending on context.

Examples:

• Vou verificar a tradução. → I’m going to check the translation.
• Precisamos verificar os dados. → We need to verify the data.

In many real situations, English check is the most natural translation, even if verify is also possible.

Yes, absolutely. It sounds natural and correct.

A Brazilian might also say similar versions such as:

• Vou verificar a tradução.
• Vou checar a tradução.
• Deixa eu verificar a tradução. = Let me check the translation.
• Eu vou dar uma olhada na tradução. = I’m going to take a look at the translation.

Your original sentence is perfectly normal and natural, especially in neutral or slightly careful speech.
