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

In Portuguese, definite articles like o, a, os, as are used more often than in English.

So A professora literally looks like the teacher, but in many contexts Portuguese uses the article where English would simply say the teacher or even just treat it as a normal subject.

For example:

• A professora chegou. = The teacher arrived.
• Professora, posso entrar? = Teacher, may I come in?

In your sentence, A professora is just the normal way to say the teacher.

Pediu is the preterite form of pedir and means asked or requested.

It refers to a completed action in the past:

• A professora pediu... = The teacher asked...

Compare:

• pede = asks / is asking
• pedia = was asking / used to ask
• pediu = asked

So this sentence is talking about one specific request that happened in the past.

After pedir, Portuguese often uses para + infinitive to say that someone asked for an action to be done.

So:

• pediu para compartilhar = asked to share

The verb after para stays in the infinitive:

• compartilhar = to share

This structure is very common:

• Ela pediu para sair. = She asked to leave.
• Ele pediu para esperar. = He asked to wait.

You cannot say pediu compartilha here, because after pediu you need either:

• para + infinitive, or
• a clause with que and a conjugated verb

For example:

• A professora pediu para compartilhar o link.
• A professora pediu que compartilhassem o link.

Both are possible, but pedir para + infinitive is very common and usually feels simpler.

Here para does not mean a physical destination like to in go to school. It is introducing the action that was requested.

So in:

• pediu para compartilhar

para is part of the pattern pedir para + infinitive, which means:

• to ask someone to do something
• to ask for something to be done

A good way to understand it is:

• pediu para compartilhar = asked for the link to be shared / asked someone to share the link

Exactly — Portuguese often leaves that implicit when context makes it clear.

A professora pediu para compartilhar o link... means:

• The teacher asked [someone] to share the link...

But the sentence does not explicitly say who that person is. It could be:

• the listener
• the speaker
• the class
• a group chat admin
• some other understood person

If Portuguese wanted to make it explicit, it could say:

• A professora me pediu para compartilhar o link... = The teacher asked me to share the link...
• A professora pediu para eu compartilhar o link... = The teacher asked for me to share the link...

Without that extra information, the doer is understood from context.

Because it is an infinitive after para.

In Portuguese, after many expressions like para, sem, antes de, and after verbs like pedir para, the next verb often appears in the infinitive form:

• compartilhar = to share
• fazer = to do
• estudar = to study

So:

• pediu para compartilhar = asked to share
• pediu para estudar = asked to study

The conjugated verb in the sentence is pediu. The second verb stays unconjugated.

Link is a borrowed word from English, and in Brazilian Portuguese it is normally treated as a masculine noun:

• o link
• um link
• os links

Many borrowed words get assigned a grammatical gender, and sometimes that gender becomes fixed by usage rather than strict logic. In modern Brazilian Portuguese, link is usually masculine.

So:

• compartilhar o link = share the link

This is a very common point of confusion.

With compartilhar, Portuguese often uses com for the person you share something with:

• compartilhar algo com alguém = to share something with someone

So:

• compartilhar o link com as outras alunas = share the link with the other female students

This matches English pretty closely:

• share the link with the others

You may also hear:

• compartilhar o link para alguém in some contexts, especially in speech or tech-related situations

But the most standard and natural pattern here is:

• compartilhar + thing + com + person

Because alunas is the feminine plural form of student.

• aluno = male student / student
• aluna = female student
• alunos = male students or mixed group
• alunas = all-female group

So as outras alunas means:

• the other female students

This tells you that the group being referred to is female.

Outras means other in the plural feminine form, agreeing with alunas.

Agreement:

• outro aluno = another / other male student
• outra aluna = another / other female student
• outros alunos = other male students / other students
• outras alunas = other female students

So:

• as outras alunas = the other female students

It implies there is some reference group already understood, and the link should be shared with the rest of them.

Yes. That is a very natural English rendering.

Portuguese often allows a slightly less explicit structure than English. Because the sentence does not name the person who should do the sharing, the meaning can be expressed in English in a few ways:

• The teacher asked to share the link with the other female students.
  This is closer to the Portuguese structure, but in English it can sound a bit awkward or ambiguous.
• The teacher asked someone to share the link with the other female students.
• The teacher asked that the link be shared with the other female students.

All of these capture the idea well.

Yes. That is another correct way to express the same general idea.

Compare:

• A professora pediu para compartilhar o link...
• A professora pediu que compartilhassem o link...

The second version uses:

• que
• a conjugated verb in the subjunctive

That structure can sound a bit more formal or more explicit in some contexts. In everyday Brazilian Portuguese, pedir para + infinitive is extremely common and often feels more straightforward.

The given order is very natural:

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

But Portuguese does allow some flexibility. For example:

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

This is grammatical, but it sounds less natural in most everyday contexts. Usually, Portuguese prefers to keep:

• the thing being shared first: o link
• then the person/people receiving it: com as outras alunas

So the original sentence is the most natural choice for normal speech and writing.
