Logo de manhã, eu abro as cortinas e bebo chá.

It means early in the morning or first thing in the morning.

Here, logo adds the idea of immediacy: not just in the morning, but right at the start of the morning.

So the feeling is:

• de manhã = in the morning
• logo de manhã = first thing in the morning / early in the morning

It is related, yes.

On its own, logo often means soon or right away depending on context. In logo de manhã, it does not mean soon in a future sense. It means something more like as soon as it is morning or right at the start of the morning.

So in this sentence, logo gives emphasis to the time expression.

Because de manhã is the most common everyday way to say in the morning.

In European Portuguese, de manhã is very natural and frequent. Pela manhã is possible, but it can sound a bit less direct or less everyday in many contexts.

Also, logo de manhã is a very natural fixed expression, so pela manhã would not fit as well here.

Because Logo de manhã is an introductory time phrase placed before the main part of the sentence.

The comma helps mark a natural pause:

Logo de manhã, eu abro as cortinas e bebo chá.

It is similar to English: In the morning, I open the curtains and drink tea.

In some informal writing, people might leave the comma out, especially with short introductory phrases, but with the comma it looks neat and natural.

No, it is not necessary.

Portuguese often leaves out subject pronouns because the verb ending already shows who the subject is.

So both of these are natural:

• Logo de manhã, eu abro as cortinas e bebo chá.
• Logo de manhã, abro as cortinas e bebo chá.

Including eu can add:

• emphasis
• clarity
• contrast

For example, if you wanted to stress I do this, not someone else, eu is useful.

They are the 1st person singular present tense forms of:

• abrir → abro
• beber → bebo

Because the subject is eu, the verbs must match I:

• eu abro = I open
• eu bebo = I drink

This is the normal present indicative tense.

In this sentence, it most naturally describes a habit or routine.

So it means something like:

• First thing in the morning, I open the curtains and drink tea.
• Early in the morning, I usually open the curtains and drink tea.

Portuguese, like English, often uses the simple present for regular actions.

Because Portuguese usually uses the definite article when talking about specific things that are understood from the context.

Here, as cortinas means the curtains — the ones in the room or house.

So:

• abro as cortinas = I open the curtains

If you said just abro cortinas, it would sound unnatural in this context.

Because chá is being used as an unspecified substance or drink, like tea in English.

So:

• bebo chá = I drink tea

This is general, not specific.

Compare:

• bebo chá = I drink tea
• bebo um chá = I drink a tea / I have a cup of tea
• bebo o chá = I drink the tea

So no article is normal here.

Yes, you could.

Both are possible:

• bebo chá
• tomo chá

The difference is slight:

• beber focuses more literally on the act of drinking
• tomar is also very common for having a drink

In European Portuguese, bebo chá is completely natural, and so is tomo chá in many situations.

Because the same subject continues for both verbs.

So:

• eu abro as cortinas e bebo chá

means:

• I open the curtains and drink tea

Portuguese does not need to repeat eu unless there is a special reason, such as emphasis or contrast.

Repeating it would sound heavier:

• eu abro as cortinas e eu bebo chá

That is grammatical, but normally unnecessary.

Yes.

For example, you could say:

• Eu abro as cortinas e bebo chá logo de manhã.

That is grammatical, but it changes the emphasis slightly.

Starting with Logo de manhã highlights the time:

• First thing in the morning...

Putting it later makes the time feel less prominent.

So the original version is natural if you want to emphasize when this happens.

In European Portuguese, manhã has a nasal sound at the end.

A useful approximation is:

• ma-NYÃ

A few key points:

• nh sounds like the ny in canyon
• the final ã is nasal, so it is not a plain a sound

And:

• chá sounds roughly like sha

So:

• de manhã ≈ d(ə) ma-NYÃ
• chá ≈ sha

The exact European Portuguese pronunciation is difficult to represent perfectly in English spelling, but those approximations are a good start.
