No verão, minha filha gosta de fazer vitamina de morango no liquidificador.

Because no is the normal contraction of em + o.

• em = in
• o = the
• em o → no

So no verão literally means in the summer.

This kind of contraction is extremely common in Portuguese:

• na escola = em + a
• nos Estados Unidos = em + os
• nas férias = em + as

Yes. Verão is a masculine noun, so it takes o in the singular:

• o verão
• no verão

Other seasons are:

• a primavera
• o outono
• o inverno

So the article changes with the noun’s gender.

The comma separates an introductory time phrase from the rest of the sentence.

So:

• No verão, minha filha gosta...

is like saying:

• In the summer, my daughter likes...

In Portuguese, this comma is very natural and common. In a short sentence, you may sometimes see it omitted, but using it here is perfectly standard.

Both are possible in Brazilian Portuguese.

• minha filha
• a minha filha

In Brazil, possessives often appear with or without the article.
So both can mean my daughter.

Very generally:

• minha filha sounds simple and natural
• a minha filha can sound a little more specific or just reflect personal/regional style

In this sentence, minha filha is completely normal.

Because the subject is already clearly stated: minha filha.

Portuguese usually does not repeat the subject with a pronoun unless there is a reason, such as emphasis or contrast.

So:

• Minha filha gosta... = normal
• Minha filha, ela gosta... = possible in speech for emphasis, but not needed here

Because the verb gostar normally requires the preposition de.

The pattern is:

• gostar de + noun
• gostar de + infinitive

Examples:

• Ela gosta de morango.
• Ela gosta de cozinhar.
• Ela gosta de fazer vitamina.

So gosta de fazer means likes to make.

You should learn gostar together with de, because that is the standard structure.

Fazer means to make, and it is very commonly used for preparing food and drinks.

So:

• fazer vitamina
• fazer café
• fazer almoço

In this sentence, fazer vitamina de morango means to make a strawberry smoothie/shake.

You could also hear preparar vitamina, but fazer is more everyday and very natural.

Not in this sentence.

In Brazilian Portuguese, vitamina can mean:

1. vitamin in the nutritional sense
2. a blended fruit drink, often made with milk

Here, because of de morango and no liquidificador, it clearly means the drink.

So this is a classic case where a familiar-looking word does not mean exactly what an English speaker might first expect.

It is close, but not always exactly the same in cultural meaning.

In Brazil, vitamina often suggests:

• fruit
• milk
• a blender

So it can be closer to a fruit shake or milk-based smoothie.

English translations like strawberry smoothie are usually fine, but the Portuguese word carries its own Brazilian food context.

Because after de, Portuguese often uses a bare noun to show:

• flavor
• ingredient
• type

So:

• suco de laranja = orange juice
• bolo de chocolate = chocolate cake
• sorvete de baunilha = vanilla ice cream
• vitamina de morango = strawberry smoothie/shake

You do not need de o morango or do morango here.

Not necessarily. Here morango is naming the flavor/type, not counting actual strawberries.

So singular is the normal form:

• vitamina de morango
• sorvete de morango
• geleia de morango

This does not mean only one strawberry is used. It just means strawberry as a category or flavor.

Literally, it means in the blender.

Portuguese often uses this kind of phrase to show where something is prepared, and it naturally implies the tool being used.

So:

• fazer vitamina no liquidificador = make a smoothie in the blender

You might also hear:

• com o liquidificador = with the blender

The difference is subtle:

• no liquidificador focuses on the container/appliance
• com o liquidificador focuses on the instrument used

Both can work, but no liquidificador sounds very natural here.

Yes. Portuguese allows some flexibility.

For example:

• No verão, minha filha gosta de fazer vitamina de morango no liquidificador.
• Minha filha gosta de fazer vitamina de morango no liquidificador no verão.

Both are grammatical.

The version with No verão first puts the seasonal context upfront, a bit like saying In the summer, ... in English.

The tricky part is lh.

In Brazilian Portuguese, lh is a palatal sound, roughly like the lli in some pronunciations of million, though not exactly the same.

So filha is approximately:

• FEE-lya

Not:

• FILL-ha
• FEE-la

This lh sound also appears in:

• trabalho
• mulher
• velho

Yes, it sounds natural.

It uses very common everyday structures:

• No verão for time
• minha filha for possession
• gosta de + infinitive
• fazer vitamina
• no liquidificador

A Brazilian speaker would understand it immediately, and it sounds like normal spoken/written Portuguese.
