Ela colocou a mão na cabeça e ficou quieta por um minuto.

This is very common in Portuguese, especially with body parts.

Instead of using a possessive like sua mão or sua cabeça, Portuguese often uses:

• the definite article
  • body part
• and lets the context show whose body part it is

So:

• Ela colocou a mão na cabeça
  literally looks like She put the hand on the head,
  but naturally means She put her hand on her head.

Using sua here is possible, but it often sounds less natural unless you really need to emphasize ownership or avoid confusion.

Na is a contraction of:

• em = in/on/at
• a = the

So:

• em + a = na

Therefore:

• na cabeça = on the head / in the head, depending on context

In this sentence, the natural meaning is on her head.

Portuguese uses em in many places where English might choose on, in, or at, so you should not expect a one-to-one match with English prepositions.

Both are in the pretérito perfeito in Brazilian Portuguese, which usually corresponds to the simple past in English.

• colocou = she put
• ficou = she became / she stayed / she was

In this sentence, the actions are understood as completed events in the past:

• She put her hand on her head
• and then she stayed/became quiet for a minute

Because ficar is often followed by an adjective, not an adverb.

• ficou quieta = she became/stayed quiet

Here, quieta describes ela, so it is an adjective.

Compare:

• Ela falou calmamente. = She spoke calmly.
  
  • calmamente is an adverb modifying the verb falou
• Ela ficou calma. = She became/stayed calm.
  
  • calma is an adjective describing ela

So ficou quieta is the normal structure.

Because adjectives in Portuguese usually agree with the noun or pronoun they describe.

Here, quieta describes ela, which is feminine singular.

So:

• ele ficou quieto
• ela ficou quieta

This kind of agreement is very important in Portuguese.

It can suggest either one, depending on context.

Ficar + adjective often means:

• to become
• to get
• to stay/remain

So ficou quieta could be understood as:

• she became quiet
• she stayed quiet
• she fell silent

In this sentence, because of por um minuto, the idea of remaining quiet for a minute is especially strong.

Yes, both are possible.

• por um minuto = for a minute
• durante um minuto = for one minute / during one minute

In everyday Brazilian Portuguese, por um minuto is very natural for duration.

Durante um minuto is also correct, but it can sound a bit more formal or a bit more explicit.

So in normal speech, por um minuto is usually the more natural choice here.

It can be literal, but it also often suggests a recognizable gesture.

Literally, it means:

• to put one’s hand on one’s head

Depending on the situation, that gesture may express things like:

• worry
• surprise
• stress
• disbelief
• tiredness

So the sentence may be describing both a physical action and an emotional reaction, even if the words themselves are literal.

Yes, very often.

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

So you could say:

• Colocou a mão na cabeça e ficou quieta por um minuto.

If the context already makes it clear that the subject is she, this is perfectly natural.

However, keeping ela can help:

• introduce the subject
• add emphasis
• avoid ambiguity

E simply means and.

It links two actions done by the same person:

• Ela colocou a mão na cabeça
• e ficou quieta por um minuto

This is very normal Portuguese sentence structure: one subject, two past actions, connected by e.

It can cover more than one of those ideas, depending on context.

Quieto/quieta in Portuguese can mean:

• quiet
• silent
• still
• calm

In this sentence, ficou quieta por um minuto most naturally means something like:

• she stayed quiet for a minute
• she fell silent for a minute

But if the broader context is about movement, it could also suggest she stayed still.

Because that version sounds much less natural in ordinary Portuguese.

Portuguese prefers the simpler structure with articles for body parts:

• colocou a mão na cabeça

Using sua twice sounds heavy and unnecessary unless you need to clarify whose hand or whose head you mean.

So for a native speaker, the original sentence is the more natural everyday phrasing.

A helpful breakdown is:

• Ela = she
• colocou = put
• a mão = the hand / her hand
• na cabeça = on the head / on her head
• e = and
• ficou = became / stayed
• quieta = quiet
• por um minuto = for a minute

So the sentence is built as:

subject + past action + body-part phrase + and + past action + adjective + duration

That pattern is very common in Portuguese storytelling and narration.
