Em janeiro, eu quero viajar com minha família.

In Portuguese, em is the normal preposition used for months, years, and many time expressions.

• em janeiro = in January
• em 2026 = in 2026
• em julho = in July

So Em janeiro is the natural way to say In January.

Yes. Portuguese often drops the subject pronoun when the verb already makes the subject clear.

• eu quero = I want
• quero by itself already shows I want

So both are correct:

• Em janeiro, eu quero viajar com minha família.
• Em janeiro, quero viajar com minha família.

Including eu can add emphasis or clarity.

After a verb like querer (to want), Portuguese normally uses the infinitive of the next verb.

• quero viajar = I want to travel
• quero comer = I want to eat
• quero descansar = I want to rest

So viajar stays in the infinitive form because it follows quero.

Viajar means to travel. It is a regular -ar verb.

Examples:

• Eu quero viajar. = I want to travel.
• Nós vamos viajar. = We are going to travel.
• Ela gosta de viajar. = She likes to travel.

Com means with, and minha família means my family.

So:

• com minha família = with my family

This is a very direct structure:

• viajar com amigos = travel with friends
• sair com a família = go out with the family

Both are possible in Brazilian Portuguese.

• minha família
• a minha família

In Brazil, people often use the definite article before a possessive, but they also often leave it out. The version without the article sounds completely natural here.

So both of these work:

• viajar com minha família
• viajar com a minha família

The accent shows the stressed syllable:

• fa-MÍ-li-a

Without the accent, the pronunciation rules would suggest a different stress pattern. The accent helps show the correct pronunciation and stress.

In Portuguese, months of the year are not capitalized, unlike in English.

So you write:

• janeiro
• fevereiro
• março

The same is true for days of the week:

• segunda-feira
• terça-feira

Yes. Portuguese allows some flexibility with word order, especially for time expressions.

All of these are natural:

• Em janeiro, eu quero viajar com minha família.
• Eu quero viajar com minha família em janeiro.
• Eu quero, em janeiro, viajar com minha família. (less common in everyday speech)

The first two are the most natural.

They express different ideas:

• quero viajar = I want to travel
• vou viajar = I am going to travel / I will travel

So in your sentence, quero viajar expresses a desire or intention, not a fixed future plan.

Compare:

• Em janeiro, eu quero viajar com minha família. = In January, I want to travel with my family.
• Em janeiro, eu vou viajar com minha família. = In January, I’m going to travel with my family.

A rough English-friendly pronunciation is:

eng zhah-NEI-roh, eh-oo KEH-roh vyah-ZHAR kong MEE-nyah fah-MEE-lyah

A few important points:

• j in janeiro sounds like the s in measure
• qu in quero sounds like k
• viajar has stress on the last syllable: via-JAR
• nh in minha is like the ny sound in canyon
• lh in família is like a soft ly sound

Brazilian pronunciation varies by region, but this is a good general guide.

It is singular.

• família = family
• famílias = families

Even though a family contains multiple people, the noun itself is singular, just like in English:

• my family is...
• minha família é...

Not in the same structure.

Pra is a common spoken form of para, but this sentence does not need para before viajar. After quero, you simply use the infinitive:

• quero viajar ✅
• quero pra viajar ❌

You would use para/pra in other kinds of sentences, for example:

• Estou economizando para viajar. = I’m saving money to travel.

It is neutral and natural. It works well in everyday speech and writing.

Nothing in it is especially formal or especially casual:

• Em janeiro = standard
• eu quero viajar = standard
• com minha família = standard

In casual speech, a Brazilian speaker might drop eu:

• Em janeiro, quero viajar com minha família.

But your original sentence is perfectly normal.
