Depois que a água ferver na chaleira, eu vou desligar o fogão e levar a frigideira para a pia.

Because after depois que, when the action is in the future, Portuguese normally uses the future subjunctive.

• Depois que a água ferver = after the water boils
• Depois que a água ferve would sound wrong here for standard Portuguese

This is a very common pattern:

• Quando eu chegar, te ligo. = When I arrive, I’ll call you.
• Se ele puder, ele vem. = If he can, he’ll come.

So ferver here is not the infinitive in function, even though it looks the same. It is the future subjunctive form of ferver.

Depois que means after when it introduces a full clause with a verb:

• Depois que a água ferver = after the water boils

Depois de is used before a noun or an infinitive:

• Depois da aula = after class
• Depois de comer = after eating

So in this sentence, because you have a subject + verb (a água ferver), depois que is the natural choice.

It looks the same, but here it is functioning as the future subjunctive, not just the plain infinitive.

That happens with many verbs in Portuguese because some future subjunctive forms are identical to the infinitive:

• fazer → quando eu fizer
• chegar → quando eu chegar
• ferver → quando a água ferver

So the form is the same in spelling, but the grammar role is different.

Because in this sentence, the water is the thing doing the action of boiling.

• A água ferver = the water boils

The verb ferver can be used in two ways:

1. Intransitive: something boils

   • A água ferveu. = The water boiled.

2. Transitive: someone boils something

   • Eu fervi a água. = I boiled the water.

Here, the sentence is talking about the moment when the water reaches boiling point by itself, so a água ferver is the right structure.

Na is a contraction of em + a:

• em a chaleira → na chaleira

So:

• na chaleira = in the kettle

This kind of contraction is extremely common in Portuguese:

• no fogão = on/in the stove (em + o)
• na pia = in/on the sink (em + a)
• do carro = of/from the car (de + o)

Ir + infinitive is very common in everyday Brazilian Portuguese to talk about the future.

• eu vou desligar = I’m going to turn off / I will turn off
• desligarei = I will turn off

Both are grammatically correct, but eu vou desligar sounds much more natural in normal conversation.

The same is true for levar here:

• eu vou desligar o fogão e levar a frigideira...

In very formal writing, you might see the simple future more often, but in speech, vou + infinitive is the default for many speakers.

Because one vou can apply to both infinitives when they are linked by e:

• eu vou desligar o fogão e levar a frigideira...

This means:

• I’m going to turn off the stove and take the frying pan to the sink.

Repeating it is possible, but usually unnecessary:

• Eu vou desligar o fogão e vou levar a frigideira para a pia.

That version is also correct, but a little less compact.

Fogão usually means stove or cooker in Brazilian Portuguese.

In this sentence, desligar o fogão means to turn off the stove / the heat source.

Depending on context, English might translate it as:

• stove
• burner
• cooktop

The exact English word depends on the situation, but fogão is the normal household word in Portuguese.

Because para a pia shows movement toward a destination:

• levar a frigideira para a pia = take the frying pan to the sink

If you said na pia, that would emphasize location:

• A frigideira está na pia. = The frying pan is in the sink / at the sink.

So:

• para a pia = to the sink
• na pia = in/at the sink

These are all everyday kitchen words:

• chaleira = kettle
• frigideira = frying pan / skillet
• pia = sink

A learner might confuse frigideira with panela, but they are not the same:

• frigideira = frying pan / skillet
• panela = pot / saucepan

So this sentence specifically says frying pan, not just any pan.

Because Depois que a água ferver na chaleira is an introductory subordinate clause.

Portuguese usually separates that kind of clause with a comma when it comes first:

• Depois que a água ferver na chaleira, eu vou desligar o fogão...

If the order were reversed, the comma might disappear more easily:

• Eu vou desligar o fogão depois que a água ferver na chaleira.

So the comma helps mark the pause and structure of the sentence.

Yes, but the meaning changes a little.

• Quando a água ferver = when the water boils
• Depois que a água ferver = after the water boils

In many real situations, they may feel quite close, but depois que is more clearly after that event has happened.

So if you want to stress sequence, depois que is better.

Because those nouns are feminine in Portuguese, so they normally take the feminine singular article a.

• a água
• a chaleira
• a frigideira
• a pia

A small detail: água is feminine, even though in some cases it can combine with forms that look unusual because of pronunciation. But grammatically, it is still feminine:

• a água fria = the cold water

So the articles in the sentence are consistent with noun gender.

Not strictly. Portuguese often drops subject pronouns when the meaning is clear.

So both are possible:

• Eu vou desligar o fogão e levar a frigideira para a pia.
• Vou desligar o fogão e levar a frigideira para a pia.

The version with eu can sound a little more explicit or emphatic. In everyday Brazilian Portuguese, including eu is very common, even when it is not required.

Usually levar means take, in the sense of moving something away from where you are now toward another place.

• levar a frigideira para a pia = take the frying pan to the sink

Its common opposite is trazer:

• trazer = bring

So in this sentence, levar is the natural verb because the frying pan is being moved to another location.
