A médica, a quem eu vou ligar amanhã, pediu-me para descansar.

Because ligar meaning to phone / to call normally takes the preposition a in standard Portuguese: ligar a alguém.

So when that person becomes a relative pronoun, the a must stay:

• a médica
• a quem eu vou ligar amanhã

For people, quem is the normal relative pronoun after a preposition here. So a quem means something like whom or the person I’m going to call.

They are different words with different jobs:

• A médica: this A is the feminine singular definite article, meaning the
• a quem: this a is a preposition, required by ligar a alguém

So even though they look the same, they are not doing the same thing.

Because that part is a non-restrictive relative clause. It gives extra information about a médica, but it is not needed to identify her.

So the structure is:

• main idea: A médica pediu-me para descansar
• extra inserted information: a quem eu vou ligar amanhã

In English, this works like:

• The doctor, whom I’m going to call tomorrow, asked me to rest.

If you removed the commas, it would sound more like you were identifying which doctor you mean, rather than just adding extra information.

Ir + infinitive is a very common way to talk about the future in Portuguese, especially in everyday speech.

So:

• vou ligar amanhã = I’m going to call tomorrow

You could also say ligarei amanhã, but that sounds more formal, more written, or simply less conversational.

Yes. Portuguese often drops subject pronouns when the verb ending already makes the subject clear.

So this is also perfectly natural:

• A médica, a quem vou ligar amanhã, pediu-me para descansar.

Keeping eu is not wrong; it just gives a little more emphasis or clarity.

In European Portuguese, unstressed object pronouns often come after the verb in affirmative main clauses. This is called enclisis.

So:

• pediu-me = asked me
• disse-me = told me
• deu-me = gave me

That is why pediu-me is the normal European Portuguese form here.

In Brazilian Portuguese, me pediu would be much more common.

Because in standard Portuguese spelling, when a clitic pronoun is attached after the verb, it is written with a hyphen.

So:

• pediu-me
• disse-lhe
• deu-nos

The hyphen shows that the pronoun is attached to the verb.

It is you / me, not the doctor.

The key part is pediu-me para descansar:

• me = the person being asked
• descansar = the action that person should do

So the meaning is:

• The doctor asked me to rest

An equivalent fuller version would be:

• A médica pediu que eu descansasse

That makes it even clearer that I am the one who should rest.

Because Portuguese often uses this pattern:

• pedir + object + para + infinitive

So:

• pediu-me para descansar = asked me to rest

This is a very common and natural structure.

A fuller alternative is:

• pediu que eu descansasse

Both are correct, but pediu-me para descansar is very natural and efficient.

Yes, à qual is grammatically possible here, because médica is feminine singular and the verb requires a.

So you could say:

• A médica, à qual vou ligar amanhã, pediu-me para descansar.

However, with people, a quem is usually the more natural choice. à qual tends to sound heavier, more formal, or more bureaucratic.

Yes. Médica is the feminine form, so it normally refers to a female doctor.

• a médica = the female doctor
• o médico = the male doctor

The article and noun agree in gender:

• a médica
• o médico
