A professora nos pediu para compartilhar o link com as outras alunas.

Here nos means us—more precisely, to us in the structure of the sentence.

With pedir, Portuguese often works like this:

• pedir algo a alguém = to ask something of someone

So in A professora nos pediu para compartilhar..., the teacher asked us to do something.

A useful thing to remember: even though English says asked us, Portuguese often treats that us more like an indirect object with pedir.

In Brazilian Portuguese, putting object pronouns before the verb is very common and natural in everyday language:

• nos pediu

The version after the verb:

• pediu-nos

is grammatically possible, but it sounds more formal, more written, or more European Portuguese in style.

So for Brazilian Portuguese learners, nos pediu is the form you will hear much more often.

Because pedir para + infinitive is a very common way to say to ask someone to do something.

So:

• pedir para compartilhar
• literally: ask to share
• natural meaning: ask someone to share

You normally would not say pediu compartilhar here. The para is part of the standard pattern.

Yes. That is also correct.

There are two common patterns:

• pedir para + infinitive
• pedir que + subjunctive

So these are both possible:

• A professora nos pediu para compartilhar o link...
• A professora nos pediu que compartilhássemos o link...

The version with para + infinitive is usually more common in everyday Brazilian Portuguese.
The version with que + subjunctive can sound a bit more formal or more explicitly structured.

Both can be correct.

You can say:

• nos pediu para compartilhar o link
• nos pediu para compartilharmos o link

The first version, with the plain infinitive compartilhar, is extremely common and natural.

The second version uses the personal infinitive (compartilharmos), which makes the subject more explicit: we/us are the ones who will share.

Since nos already tells you who was asked, the simple infinitive compartilhar is enough and very common.

Because in Brazilian Portuguese, link is normally treated as a masculine noun:

• o link
• os links

This is just the established usage. Loanwords in Portuguese get grammatical gender, and with link, masculine is the standard choice.

So learners should simply memorize:

• o link

Because compartilhar commonly follows this pattern:

• compartilhar algo com alguém = to share something with someone

So in this sentence:

• o link = the thing being shared
• com as outras alunas = the people receiving it

Here com does not mean the speaker is doing the action together with them. It marks who the link is being shared with.

Outras means other and agrees with alunas in gender and number.

So:

• outras alunas = other female students

It suggests a contrast with some group already in the context. For example, it may imply:

• us and the other students
• these students and the rest
• some students already mentioned, plus other ones

Without outras, com as alunas would be more general and less specific.

Because the sentence is referring to a female group of students.

In Portuguese, articles and adjectives must agree with the noun:

• as outras alunas

Everything is feminine plural:

• as = feminine plural article
• outras = feminine plural adjective
• alunas = feminine plural noun

If the group were all male, or mixed in the traditional grammatical system, you would usually see:

• os outros alunos

Because Portuguese normally uses the definite article with a specific person or role being referred to:

• A professora = the teacher

That is very normal.

Compare:

• A professora nos pediu... = talking about the teacher
• Professora, posso entrar? = directly addressing her

So when you are referring to a specific teacher, A professora is exactly what you would expect.

Because com normally does not contract with definite articles in modern standard Portuguese.

So you say:

• com as outras alunas
• com o professor
• com a turma

This is different from other common contractions such as:

• de + o = do
• em + a = na
• a + as = às

So com as staying separate is completely normal.
