Vull saber el sentit.

Vull is the 1st person singular present form of the verb voler, which means to want.

So:

• vull = I want
• vols = you want
• vol = he/she/it wants

It is an irregular verb, so you cannot always predict its forms from the infinitive.

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

So:

• Vull saber el sentit. = I want to know the meaning/sense.
• Jo vull saber el sentit. also works, but jo adds emphasis, contrast, or clarity.

A native speaker would usually leave jo out unless there is a reason to stress I.

After voler (to want), Catalan normally uses another verb in the infinitive directly after it.

So:

• vull saber = I want to know
• vull menjar = I want to eat
• vull anar = I want to go

There is no extra word like to in English.

This is a very common question.

In Catalan:

• saber = to know a fact, a piece of information, or how to do something
• conèixer = to know a person, place, or be familiar with something

Since el sentit is information or meaning, saber fits better.

Compare:

• Sé la resposta. = I know the answer.
• Conec aquesta ciutat. = I know this city.

Sentit is a noun that can mean several related things, depending on context:

• sense
• meaning
• direction
• purpose
• point

In this sentence, it means something like the sense or the meaning.

It comes from the verb sentir (to feel, to hear, depending on context), but as a noun sentit has its own range of meanings.

El is the masculine singular definite article, meaning the.

So:

• el sentit = the sense / the meaning

Catalan uses definite articles in many places where English may or may not use the. Here it sounds like a specific meaning/sense, not just meaning in general.

Also, sentit is a masculine noun, so it takes el.

Yes. Vull saber el sentit follows a very normal pattern:

• Vull = main verb
• saber = infinitive
• el sentit = object

This is a natural basic order in Catalan.

You could change the order for emphasis in some contexts, but this version is the neutral one.

A rough pronunciation guide is:

• Vull ≈ bool or booy, depending on dialect
• saber ≈ suh-BEHR
• el ≈ uhl
• sentit ≈ sen-TEET

A few useful notes:

• In most Catalan accents, v is pronounced like b
• The ll sound can vary by dialect:
  • in some places it sounds like a soft ly
  • in others it sounds closer to y
• sentit is stressed on the last syllable

Not always. The sentence is grammatical, but the most natural wording depends on what kind of meaning you mean.

For example:

• Vull saber què vol dir. = I want to know what it means.
• Vull saber què significa. = I want to know what it means.
• Vull entendre el sentit. = I want to understand the sense/point.

So Vull saber el sentit is possible, but in many real situations a speaker might choose a more specific expression.
