Eu concordo com você, mas quero ouvir a opinião da Ana também.

Because concordar normally takes com when you say you agree with someone or something.

• concordo com você = I agree with you
• concordo com isso = I agree with that

You can also see other patterns, such as:

• concordo que... = I agree that...
• concordo em... = I agree to/on... in some contexts

But in this sentence, com você is the standard choice.

Yes. In Portuguese, subject pronouns are often omitted because the verb ending already shows the subject.

So both are natural:

• Eu concordo com você...
• Concordo com você...

Keeping eu can add a little emphasis, contrast, or clarity.

Yes, concordo contigo is correct. It also means I agree with you.

In Brazilian Portuguese, though, com você is usually the most neutral and widely usable form. Contigo may sound more tied to regions or situations where tu is more common.

So for a learner, concordo com você is a very safe, natural choice.

After querer and many other verbs, the next verb stays in the infinitive.

So:

• quero ouvir = I want to hear
• quero falar = I want to speak
• quero entender = I want to understand

This works much like English want to + verb.

In everyday Brazilian Portuguese, they are often very close in meaning, and many people use them almost interchangeably.

A common rough distinction is:

• ouvir = to hear / to listen
• escutar = to listen, sometimes with a sense of more active attention

So in this sentence, quero ouvir a opinião da Ana is completely natural. You could also hear quero escutar a opinião da Ana, but ouvir is very common.

Because a opinião da Ana refers to a specific opinion: Ana’s opinion.

Portuguese uses definite articles more often than English, especially with specific nouns. So:

• quero ouvir a opinião da Ana = I want to hear Ana’s opinion

Without the article, the phrase would sound less natural here.

Da is a contraction of:

• de + a = da

So:

• a opinião da Ana literally corresponds to the opinion of Ana
• naturally in English: Ana’s opinion

Portuguese very often contracts prepositions with articles like this:

• de + o = do
• de + a = da
• em + a = na
• a + o = ao

In many varieties of Brazilian Portuguese, people often use a definite article before a person’s first name:

• a Ana
• o João

So de + a Ana becomes da Ana.

This is very common and natural in Brazil, especially in speech. In some regions or styles, you may also see de Ana without the article. Both exist, but da Ana sounds very normal in Brazilian Portuguese.

Yes, também can move, but its position affects the emphasis.

In this sentence:

• quero ouvir a opinião da Ana também

the idea is I want to hear Ana’s opinion too / as well.

If you move it:

• Eu também concordo com você... = I also agree with you
• mas também quero ouvir... = but I also want to hear...

So the final também is natural because it highlights the extra opinion being added.

No. This is a very common confusion.

• mas = but
• mais = more

So here:

• Eu concordo com você, mas... = I agree with you, but...

They are pronounced differently too, although learners often mix them up at first.

They mainly help show stress and pronunciation.

• opinião: the stressed part is the final -ão
• também: the stressed part is -bém

A few useful notes:

• ã in opinião is nasal
• final -ão is a very common Brazilian Portuguese ending
• final -ém in também is also stressed and nasalized

So the accents are not optional spelling marks; they are part of the correct written form and help guide pronunciation.

Yes, this sentence is very natural in Brazilian Portuguese.

Eu concordo com você, mas quero ouvir a opinião da Ana também.

It sounds conversational, clear, and idiomatic. A speaker might make small changes depending on tone or emphasis, for example:

• Concordo com você, mas também quero ouvir a opinião da Ana.
• Concordo com você, mas quero ouvir o que a Ana acha também.

But your original sentence already sounds like something a native speaker could naturally say.
