No parque, a criança entrou na casinha e depois foi para o balanço.

No parque means in the park.

Portuguese often allows a place expression to come first to set the scene, just like English can do with In the park, .... It gives the sentence a natural storytelling feel.

So:

• No parque, a criança entrou na casinha...
• literally: In the park, the child entered the little house...

You could also say:

• A criança entrou na casinha no parque...

But that changes the focus a little and sounds less like scene-setting.

Because no is a contraction:

• em + o = no

And parque here uses the masculine singular article o:

• o parque = the park
• em o parque becomes no parque

This kind of contraction is extremely common in Portuguese:

• em + a = na
• em + os = nos
• em + as = nas

So in this sentence:

• no parque = in the park
• na casinha = in the little house

Here a is the definite article, meaning the.

• a criança = the child

Even if English might sometimes say a child in a similar sentence, Portuguese often uses the definite article when referring to a specific person or thing already understood in the context.

Also, criança is grammatically feminine, so it takes a, even if the child could be a boy or a girl.

• a criança = grammatically feminine noun
• this does not necessarily mean the child is female

Because grammatical gender and real-world gender are not always the same thing.

In Portuguese, criança is a feminine noun, so it takes feminine agreement:

• a criança
• a criança pequena
• a criança entrou

But it can refer to:

• a girl
• a boy
• a child of unspecified gender

This is very common in Portuguese. The noun has a grammatical gender, even when the person referred to could be male or female.

Casinha is the diminutive form of casa.

• casa = house
• casinha = little house, small house, little playhouse

The ending -inha often adds the idea of:

• small size
• affection
• cuteness
• sometimes informality

In this sentence, casinha probably refers to a small play structure in a park, not a regular full-size house.

So entrou na casinha most likely means the child went into the little playhouse.

Yes. In Portuguese, entrar normally uses the preposition em when you say where someone entered.

• entrar em = to go into, to enter

Because em + a = na, you get:

• entrou na casinha = entered the little house / went into the little house

This is different from English, where enter can take a direct object:

• English: entered the house
• Portuguese: entrou na casa

So for learners, it helps to remember:

• entrar em algum lugar
• not usually entrar algum lugar

Foi para o balanço means the child went to the swing.

Here para shows direction or destination:

• ir para = to go to, to head toward

So:

• foi para o balanço = went to the swing

A few comparisons:

• foi para o balanço = went toward the swing / went over to the swing
• foi no balanço would sound less natural here if you mean movement toward it
• foi ao balanço is possible in some contexts, but para o balanço is very natural in Brazilian Portuguese when talking about heading to that place or object

Also, this phrase usually means the child went over to the swing area or to use the swing. It does not automatically mean the child got on it. If you wanted to be more explicit, you could say:

• foi brincar no balanço
• subiu no balanço
• sentou no balanço

In this context, balanço means swing, like the playground swing.

The word balanço can have other meanings in Portuguese depending on context, such as:

• swaying
• balance
• rocking motion
• financial balance sheet

But in a sentence about a child in a park, o balanço is naturally understood as the swing.

Both entrou and foi are in the preterite tense, which is used for completed actions in the past.

• entrou = entered / went in
• foi = went

This tense is very common for telling a sequence of events:

• first the child entered the little house
• then the child went to the swing

That is why it fits well with depois:

• entrou ... e depois foi ...
• entered ... and then went ...

If you are learning past tenses, this is a classic example of the preterite for finished actions in a story.

Depois means afterward, then, or later.

It shows the order of events:

1. a criança entrou na casinha
2. depois foi para o balanço

So it helps the listener understand that one action happened after the other.

In this sentence, depois is placed between the two actions very naturally:

• ... entrou na casinha e depois foi para o balanço

You could also see it in other positions, such as:

• Depois, a criança foi para o balanço
• A criança entrou na casinha; depois, foi para o balanço

In Portuguese, nouns often appear with articles much more often than in English.

So para o balanço is the normal way to say to the swing.

Without the article, para balanço, the phrase would sound incomplete or unnatural in this context.

This is something English speakers often need to get used to:

• Portuguese frequently uses articles where English may not focus on them as much
• especially with concrete nouns like places and objects

So here the natural form is:

• o balanço
• para o balanço

Not exactly. Foi para o balanço most directly means went to the swing or went over to the swing.

It suggests movement toward that place or object, but it does not clearly state that the child sat on it or started swinging.

If you wanted to say that more specifically, Portuguese might use:

• foi brincar no balanço = went to play on the swing
• sentou no balanço = sat on the swing
• subiu no balanço = got onto the swing

So the original sentence leaves that detail open.

The comma is natural and helpful because No parque is an introductory location phrase.

• No parque, a criança entrou na casinha...

It separates the scene-setting part from the main clause.

In informal writing, some people might omit it, but using the comma is standard and clear here. It is especially common when a sentence begins with a short phrase of time or place:

• Na escola, os alunos estudaram.
• De manhã, ela saiu cedo.
• No parque, a criança entrou na casinha.
