Por mais que chova, a torcida vai cantar.

Por mais que introduces a concession: it shows that one thing will be true despite another.

In this sentence, it means something like:

• no matter how much
• even if
• however much

So Por mais que chova means that the rain does not change what happens next.

A very common pattern is:

• Por mais que + subjunctive, ...

Examples:

• Por mais que eu estude, ainda erro.
• Por mais que ele tente, não consegue.

It is a strong way to say despite that situation, the result stays the same.

Because por mais que normally requires the subjunctive.

• chove = present indicative
• chova = present subjunctive

Portuguese uses the subjunctive after expressions that involve:

• uncertainty
• hypothesis
• concession
• emotion
• doubt

Here, the rain is not being presented as a simple fact. It is part of a concessive idea: even if it rains / no matter how much it rains. That is why chova is used.

With chover, the present subjunctive forms are:

• que chova
• que chova
• que chova
• que chovamos
• que chovais
• que chovam

Since chover is usually impersonal, in real life you mostly see chova.

Because chover is usually an impersonal verb in Portuguese, just like to rain in English when used for weather.

Portuguese does not need a dummy subject like it in it rains.

So:

• Chove muito. = It rains a lot.
• Se chover... = If it rains...
• Por mais que chova... = No matter how much it rains...

There is no word equivalent to English weather it here.

A torcida usually means the fans, the supporters, or the crowd cheering for a team.

It comes from torcer, which in sports contexts means to root for a team.

So:

• torcedor = a male supporter/fan
• torcedora = a female supporter/fan
• torcida = the fan base / the supporters as a group

In Brazilian Portuguese, a torcida is extremely common in sports language.

Examples:

• A torcida chegou cedo ao estádio.
• A torcida apoiou o time o jogo inteiro.

Because a torcida is grammatically singular.

Even though it refers to many people, it is a collective noun, so the verb agrees with the singular noun:

• A torcida vai cantar.

This is similar to English ideas like the crowd is singing in American English.

Other examples:

• A equipe vai treinar amanhã.
• O grupo chegou cedo.
• A multidão começou a gritar.

If you used a plural subject, then the verb would be plural:

• Os torcedores vão cantar.

Vai cantar is the near future / periphrastic future:

• vai = present of ir
• cantar = infinitive

So:

• a torcida vai cantar = the fans are going to sing / will sing

This structure is extremely common in spoken Brazilian Portuguese and often sounds more natural than the simple future.

Compare:

• A torcida vai cantar. = very common in speech
• A torcida cantará. = also correct, but usually more formal or less common in everyday speech

Yes, that would be grammatically correct:

• Por mais que chova, a torcida cantará.

But in Brazilian Portuguese, ir + infinitive is usually more common in everyday language:

• vai cantar
• vai chover
• vamos ver

The simple future (cantará) is often:

• more formal
• more literary
• more common in writing than in casual speech

So vai cantar sounds very natural.

Sometimes yes, but the nuance changes a little.

• Mesmo que chova, a torcida vai cantar.
  = Even if it rains, the fans will sing.

• Por mais que chova, a torcida vai cantar.
  = No matter how much it rains / however much it rains, the fans will sing.

So:

• mesmo que focuses more on even if that happens
• por mais que often adds the idea of regardless of degree/intensity

With chover, that difference is especially noticeable because rain can vary in amount. So por mais que chova strongly suggests even if it rains a lot.

Because the sentence begins with a subordinate concessive clause:

• Por mais que chova, = subordinate clause
• a torcida vai cantar. = main clause

In Portuguese, when this kind of clause comes first, it is normally separated by a comma.

Compare:

• Se chover, ficamos em casa.
• Embora esteja cansado, ele continua.
• Por mais que chova, a torcida vai cantar.

The comma helps show the division between the introductory clause and the main statement.

It can definitely mean the kind of singing/chanting fans do in a stadium.

In sports contexts, cantar often refers not just to singing a song in a musical sense, but to:

• chanting
• singing team songs
• shouting rhythmic support

So a torcida vai cantar sounds very natural in a soccer or stadium context.

Yes. This is a very useful pattern.

Structure:

• Por mais que + subjunctive, ...

Examples:

• Por mais que eu tente, não consigo.
• Por mais que ele fale, ninguém escuta.
• Por mais que estudemos, sempre há mais para aprender.

With adjectives or adverbs, you can also see:

• Por mais difícil que seja...
• Por mais cedo que chegue...

So this is a productive structure, not just a one-off phrase.

Very often, yes, but the best English translation depends on context.

Possible translations include:

• no matter how much
• however much
• even though
• even if

The core idea is usually concession: something remains true despite another factor.

In this sentence, because chover naturally suggests amount/intensity, no matter how much it rains is a very natural fit.

The original sentence already sounds natural. But depending on the situation, Brazilians might also say:

• Mesmo se chover, a torcida vai cantar.
• Mesmo com chuva, a torcida vai cantar.
• Pode chover à vontade, a torcida vai cantar.
• Chova o quanto chover, a torcida vai cantar.

These versions vary in style and emphasis, but the original is perfectly good and idiomatic, especially in a dramatic or emphatic context.
