Por mais que o árbitro apite, a torcida continua cantando.

Por mais que is a fixed expression that introduces a contrast, often like no matter how much, however much, or even if.

In this sentence, it sets up the idea that one thing happens despite another:

• Por mais que o árbitro apite... = No matter how much the referee blows the whistle...

It is very commonly used to show that an effort, action, or circumstance does not change the result in the main clause.

A few similar examples:

• Por mais que eu estude, ainda erro isso.
  = No matter how much I study, I still get this wrong.

• Por mais que chova, eles vão sair.
  = Even if it rains a lot, they are going out.

Because por mais que normally triggers the subjunctive.

The verb apitar would be:

• apita = present indicative
• apite = present subjunctive

Since the phrase expresses concession or uncertainty rather than a simple factual statement, Portuguese uses the subjunctive:

• Por mais que o árbitro apite...

This is one of the most useful patterns to remember:

• por mais que + subjunctive

More examples:

• Por mais que ele tente, não consegue.
• Por mais que vocês estudem, ainda terão dúvidas.

The subjunctive here shows that the clause is not just stating a plain fact. It presents something as a condition, concession, or repeated possibility that does not affect the result.

So the structure is:

• Por mais que + subjunctive = no matter how / even if / however much

The important idea is not whether the referee whistles once, twice, or many times. The point is that his action does not stop the crowd.

That is why the sentence contrasts:

• o árbitro apite → the referee may whistle, keeps whistling, whistles as much as he wants
• a torcida continua cantando → the crowd keeps singing anyway

Portuguese uses definite articles much more often than English.

So where English often says:

• the referee
• or sometimes just referee in a general sports context

Portuguese naturally says:

• o árbitro

This is normal and does not necessarily mean a very specific dramatic emphasis. It is just standard Portuguese usage.

You will see this a lot with professions and roles:

• O professor explicou tudo.
• A médica chegou cedo.
• O motorista parou o carro.

Literally, apitar means to blow a whistle or to whistle.

With a referee, it specifically refers to the act of using the whistle during a game:

• O árbitro apita. = The referee blows the whistle.

In sports contexts, it can also sometimes extend to the idea of refereeing or calling fouls, depending on context. But in this sentence, the most immediate image is that the referee is repeatedly blowing the whistle to interrupt or control play, while the crowd keeps singing.

Because the two clauses do different jobs.

1. Por mais que o árbitro apite
   This is a concessive clause, so it uses the subjunctive.

2. a torcida continua cantando
   This is the main statement, so it uses the indicative.

So:

• apite = part of the concession
• continua = the actual result or main fact being asserted

This contrast is very common in Portuguese:

• Embora ele estude, não aprende.
• Mesmo que chova, vamos sair.
• Por mais que eu explique, ela não entende.

In each case, the subordinate clause tends to take the subjunctive, while the main clause stays in the indicative.

Torcida usually means the fans, the supporters, or the crowd of supporters, especially in sports.

In Brazilian Portuguese, it is a very common football word.

Examples:

• A torcida cantou o jogo inteiro.
  = The fans sang the whole game.

• A torcida do Flamengo
  = Flamengo’s supporters / fan base

Although it refers to many people, torcida is grammatically singular, because it is a collective noun, similar to the crowd in English.

That is why the sentence says:

• a torcida continua not
• a torcida continuam

Because Portuguese often uses continuar + gerund to express keep doing something or continue doing something.

So:

• continua cantando = keeps singing / continues singing

This is very natural in Brazilian Portuguese.

Other examples:

• Ele continua falando.
  = He keeps talking.

• Estamos continuando a trabalhar.
  = We are continuing to work.

In Brazil, continuar + gerund is especially common in everyday speech.

Yes, grammatically that is possible:

• a torcida continua a cantar

But there is a usage difference.

In Brazilian Portuguese, continuar + gerund is very common and sounds natural in everyday speech:

• continua cantando

In European Portuguese, continuar a + infinitive is usually more common:

• continua a cantar

So for Brazilian Portuguese, the original sentence sounds very natural.

Because torcida is a collective noun. It refers to a group as a single unit.

Just like in English:

• The crowd is singing.
• The audience is cheering.

Portuguese does the same:

• A torcida continua cantando.

If you wanted to focus on the individual fans rather than the group as a unit, you might say:

• Os torcedores continuam cantando.
  = The supporters keep singing.

So both are possible, but they frame the group differently:

• a torcida = the crowd/fan base as one unit
• os torcedores = the individual supporters

In this concessive pattern, yes, usually.

When por mais que means no matter how much / however much, it is normally followed by the subjunctive:

• Por mais que eu tente...
• Por mais que ela fale...
• Por mais que eles estudem...

This is the pattern learners should remember.

There may be rare edge cases in very specific contexts, but as a practical rule for learning Brazilian Portuguese, you can safely treat it as:

• por mais que + subjunctive

In this sentence, it is best understood as repeated or ongoing action, not just a single whistle.

That happens because of the expression por mais que, which often implies however much or no matter how many times.

So the idea is:

• the referee may whistle again and again
• but the crowd keeps singing anyway

Even though apite is just a simple verb form, the overall expression gives it that broader repeated sense.

Yes. Portuguese is fairly flexible here.

The original order is:

• Por mais que o árbitro apite, a torcida continua cantando.

You could also say:

• A torcida continua cantando, por mais que o árbitro apite.

That keeps the same basic meaning, but the focus changes slightly:

• original order: starts with the contrast
• changed order: starts with the main fact

The original version feels very natural and elegant because it presents the obstacle first and then the unaffected result.

Árbitro has the stress on the first syllable:

• ÁR-bi-tro

The accent mark on á shows that stress clearly.

This matters because Portuguese stress is not always predictable just from spelling, so the accent helps you pronounce it correctly.

Also note that in Brazilian Portuguese, the r sound and unstressed vowels may vary somewhat by region, but the main stress stays the same:

• ÁR-bi-tro

A very useful way to see it is:

• Por mais que + subject + subjunctive, main clause in the indicative

So this sentence breaks down as:

• Por mais que = concessive expression
• o árbitro = subject of the subordinate clause
• apite = present subjunctive
• a torcida = subject of the main clause
• continua cantando = main verb phrase

You can reuse this model with many verbs:

• Por mais que eu explique, ele não entende.
• Por mais que eles insistam, não vou mudar de ideia.
• Por mais que você corra, não vai chegar a tempo.

It is a very high-value structure for sounding natural in Portuguese.
