Vull tornar a trucar a la secretària demà.

Catalan often drops subject pronouns when they are not needed, because the verb ending usually already shows who the subject is.

• vull = I want
• jo vull = I want / I, personally, want

So Vull tornar a trucar... is the normal, natural way to say it. You would add jo only for emphasis, contrast, or clarity.

Example:

• Jo vull trucar, però ell no. = I want to call, but he doesn’t.

Because voler is an irregular verb.

Its first-person singular present form is:

• jo vull = I want

Some other present-tense forms are:

• tu vols
• ell/ella vol
• nosaltres volem
• vosaltres voleu
• ells/elles volen

So vull is just the normal irregular I form of voler.

Tornar a + infinitive means to do something again.

So:

• tornar a trucar = to call again

This is a very common Catalan structure.

Examples:

• Tornar a començar = to start again
• Tornar a veure = to see again
• Tornar a intentar-ho = to try it again

Without a, tornar usually means to return / to come back.

Compare:

• Torno demà. = I’m coming back tomorrow.
• Torno a trucar demà. = I’m calling again tomorrow.

They do two different jobs.

1. tornar a + infinitive
   Here, a belongs to the structure meaning again:

   • tornar a trucar = to call again

2. trucar a algú
   Here, a is required by the verb trucar when you say who you are calling:

   • trucar a la secretària = to call the secretary

So the sentence has:

• one a after tornar
• another a after trucar

That is completely normal.

Because in Catalan, trucar normally takes a before the person you call.

So:

• trucar a algú = to call someone

Examples:

• Truco a la Maria.
• Has trucat al metge?
• Vull trucar a la secretària.

This is different from English, where we usually say call someone without a preposition.

Yes. Since trucar a algú uses an indirect object-style pronoun, you normally use li for to him / to her / to you (formal).

So you can say:

• Li vull tornar a trucar demà.
• Vull tornar a trucar-li demà.

Both mean I want to call her again tomorrow.

A very important point for English speakers:

• You do not normally use la here
• because trucar takes a algú, so Catalan uses li

Catalan word order is fairly flexible, especially with time expressions like demà.

Your sentence:

• Vull tornar a trucar a la secretària demà.

Other possible orders:

• Demà vull tornar a trucar a la secretària.
• Vull demà tornar a trucar a la secretària.
  This is possible, though a bit less neutral in many contexts.

The most natural position often depends on what you want to emphasize:

• Demà at the beginning highlights the time
• demà at the end sounds very natural and neutral

No. Demà can appear in different places.

Common options:

• Demà truco a la secretària.
• Truco a la secretària demà.
• Demà vull tornar a trucar-hi.

Catalan allows this kind of movement more freely than English in many cases. The meaning usually stays the same, but the focus changes slightly.

Because secretària is a feminine singular noun, so it takes the feminine singular article la.

• la secretària = the secretary

Masculine equivalent:

• el secretari = the male secretary

The ending -a often signals feminine nouns, though not always.

The accent mark in secretària shows the stressed syllable.

It is pronounced roughly like:

• se-cre-TÀ-ri-a

Without the accent, Catalan stress rules would suggest a different pronunciation. So the written accent helps show the correct stress.

A broad pronunciation guide is:

• Vull tornar a trucar a la secretària demà
• roughly: bool tor-NAR a troo-KAR a la sek-re-TA-ree-a de-MA

A few notes:

• vull sounds roughly like bool with a Catalan ll
• trucar has stress on the last syllable: tru-CAR
• secretària is stressed on tà
• demà is stressed on the last syllable: de-MÀ

Depending on the variety of Catalan, pronunciation details can vary.

Yes, in many contexts tornar a trucar can correspond to English call again or call back.

Examples:

• Et tornaré a trucar més tard. = I’ll call you back / I’ll call you again later.
• Vull tornar a trucar a la secretària. = I want to call the secretary again.

If the context is returning a phone call, English often says call back, while Catalan still commonly uses tornar a trucar.

Yes, that is possible, but it sounds a bit more marked or literary than the more neutral:

• Vull tornar a trucar a la secretària demà.
• Demà vull tornar a trucar a la secretària.

Placing demà between tornar and a trucar is not the most straightforward option for a learner. It is better to use one of the more common word orders above.

It breaks down like this:

• Vull = I want
• tornar a trucar = to call again
• a la secretària = the secretary
• demà = tomorrow

So the grammar pattern is:

• [conjugated verb] + [infinitive expression] + [object/complement] + [time expression]

More specifically:

• Vull
  • tornar a trucar
    • a la secretària
      • demà

This is a very common and useful Catalan sentence pattern.
