Finalmente chegamos.

Portuguese often drops subject pronouns when the verb ending already shows who the subject is.

In chegamos, the ending -amos tells you the subject is we (nós). So:

• Finalmente chegamos. = We finally arrived.
• Finalmente nós chegamos. = also possible, but nós is usually unnecessary unless you want emphasis or contrast.

This is very common in Brazilian Portuguese.

Here, chegamos is most naturally understood as the preterite: we arrived.

So in this sentence:

• Finalmente chegamos. = We finally arrived.

A very important detail: for -ar verbs, the nós form in the present and the preterite is often the same in spelling:

• chegamos = we arrive
• chegamos = we arrived

Context tells you which one it is. With finalmente, the past meaning is the most likely one.

The infinitive is chegar, meaning to arrive.

A few useful forms are:

• eu chego = I arrive
• você chega = you arrive
• nós chegamos = we arrive / we arrived
• eles chegam = they arrive

In your sentence, chegamos comes from chegar.

Usually, yes. Finalmente often matches English finally very closely.

In this sentence, it adds the idea that something took time, effort, or delay:

• Finalmente chegamos. = We finally arrived.

That said, finalmente can sound a little more formal or narrative in some contexts. In everyday speech, Brazilians may also use words like:

• enfim
• por fim
• até que enfim

But finalmente is completely correct and natural.

Yes, you can, but Finalmente chegamos is the more natural order for this kind of sentence.

Compare:

• Finalmente chegamos. = the adverb is highlighted first; very natural
• Chegamos finalmente. = also possible, but sounds a bit more literary or stylistically marked

Putting finalmente first is a very common way to emphasize the feeling of relief or completion.

Because Portuguese normally uses chegar for arrive / get there.

So:

• chegar = to arrive
• ir = to go
• vir = to come

If you say:

• Finalmente chegamos. = We finally arrived.

But:

• Finalmente fomos. would mean We finally went, not we finally arrived

So chegar is the right verb when the focus is the endpoint of the trip.

A simple English-friendly approximation is:

fee-nahl-MEN-chee sheh-GAH-moos

A few pronunciation notes:

• finalmente
  
  • the stress is on men: final-MEN-te
• ch in chegamos sounds like sh
• g before a is a hard g, like in go
• the stress in chegamos is on ga: che-GA-mos

A more accurate Brazilian pronunciation would be roughly:

fee-naw-MEN-tchee sheh-GAH-moos

The exact sound varies a bit by region.

Usually, no comma is necessary in a short sentence like this:

• Finalmente chegamos.

But you may also see:

• Finalmente, chegamos.

That comma adds a small pause and can make the sentence feel a little more dramatic or deliberate. In everyday writing, the version without the comma is very common.

Yes, grammatically that is correct. But most of the time, native speakers would simply say:

• Finalmente chegamos.

Adding nós can sound more emphatic, especially if you are contrasting we with someone else:

• Eles não chegaram, mas nós chegamos. = They didn’t arrive, but we did.

So in a neutral sentence, leaving out nós is more natural.
