Vull estudiar a casa perquè demà tinc un examen important.

After vull (I want), Catalan uses an infinitive, just like English does in I want to study.

• vull = I want
• estudiar = to study

So:

• Vull estudiar = I want to study

You would not say vull estudio because estudio is a conjugated form (I study), and Catalan does not normally put two conjugated verbs together in this structure.

In Catalan, after verbs like voler (to want), the infinitive usually comes directly after the verb, without a separate word for to.

So:

• Vull estudiar literally looks like I want study
• but it means I want to study

This is very common in Catalan and other Romance languages.

Catalan often leaves out subject pronouns because the verb ending already shows who the subject is.

• vull already means I want
• tinc already means I have

So jo is not necessary.

You can include jo for emphasis, contrast, or clarity:

• Jo vull estudiar a casa = I want to study at home

But in a neutral sentence, leaving it out sounds more natural.

A casa is a very common Catalan expression meaning at home or to home/home depending on context.

In this sentence:

• estudiar a casa = to study at home

Catalan normally uses casa without the article in this expression. It works a bit like a fixed phrase.

Compare:

• Sóc a casa = I’m at home
• Vaig a casa = I’m going home
• Estudio a casa = I study at home

If you say la casa, you are usually talking about a specific house as a physical building, not the general idea of home.

Yes. The exact meaning depends on the verb and the context.

For example:

• Sóc a casa = I’m at home
• Vaig a casa = I’m going home
• Vull estudiar a casa = I want to study at home

So a casa is very flexible, and learners usually understand it best as the normal expression connected with home.

In this sentence, perquè means because, and it is written with a grave accent: è.

• perquè = because

This is important because Catalan has several similar-looking forms:

• perquè = because
• per què = why / for what reason
• per a què = what for / for what purpose

So here:

• Vull estudiar a casa perquè demà tinc un examen important
• I want to study at home because tomorrow I have an important exam

The accented form is the correct one for because.

Demà means tomorrow, and in Catalan adverbs of time are often placed before the main clause they modify.

So:

• perquè demà tinc un examen important = because tomorrow I have an important exam

This word order is very natural in Catalan. You could also hear:

• perquè tinc un examen important demà

Both are possible, but placing demà early in the clause often sounds very natural and helps highlight the time.

Catalan commonly uses tenir (to have) for events or obligations that a person has scheduled, just like English does.

• tinc un examen = I have an exam
• tenim classe = we have class
• té una reunió = he/she has a meeting

So this structure is very normal and idiomatic.

In Catalan, adjectives usually come after the noun.

So:

• un examen important = an important exam

This noun + adjective order is the normal pattern:

• una casa gran = a big house
• un llibre interessant = an interesting book
• un examen important = an important exam

Sometimes adjectives can come before the noun, but that often changes the tone or emphasis. For everyday speech, examen important is the expected order.

Vull is the first person singular form of the verb voler (to want).

Here are a few forms of voler in the present tense:

• vull = I want
• vols = you want
• vol = he/she/it wants
• volem = we want
• voleu = you all want
• volen = they want

So in this sentence:

• Vull estudiar = I want to study

It is an irregular verb, so it is worth memorizing.

Tinc is the first person singular form of tenir (to have).

A few present-tense forms are:

• tinc = I have
• tens = you have
• té = he/she/it has
• tenim = we have
• teniu = you all have
• tenen = they have

So:

• demà tinc un examen important = tomorrow I have an important exam

Like voler, tenir is an important verb to learn early.

Yes, Catalan allows some flexibility in word order, especially with time expressions and subordinate clauses.

For example, these are all possible:

• Vull estudiar a casa perquè demà tinc un examen important.
• Perquè demà tinc un examen important, vull estudiar a casa.
• Demà tinc un examen important, per això vull estudiar a casa.

However, the original version sounds very natural and straightforward.

You could add emphasis in a few ways:

• Jo vull estudiar a casa perquè demà tinc un examen important.
• Vull estudiar a casa, perquè demà tinc un examen molt important.
• És que demà tinc un examen important, i vull estudiar a casa.

Adding jo emphasizes I. Adding molt strengthens important. Changing the structure can make the reason sound more prominent.

The original sentence is neutral and natural, which makes it a very good model for learners.
