Estic preocupada perquè encara no trobo la solució.

In Catalan, temporary states are usually expressed with estar, not ser.

• estic preocupada = I am worried
• sóc... is more for identity, inherent characteristics, profession, origin, etc.

So estic preocupada means the speaker is in a worried state right now. Using sóc preocupada would sound more like I am a worried/anxious person by nature, which is not the intended meaning here.

Because the adjective agrees with the speaker’s gender.

• preocupat = masculine singular
• preocupada = feminine singular

So if a woman is speaking, she says estic preocupada.
If a man is speaking, he says estic preocupat.

This agreement is very common in Catalan adjectives and past participles used adjectivally.

Here perquè means because.

So:

• Estic preocupada perquè... = I’m worried because...

A common learner issue is confusing perquè with similar-looking forms:

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

In this sentence, it clearly introduces the reason, so perquè = because.

Encara no means not yet.

So:

• encara no trobo la solució = I still haven’t found the solution / I haven’t found the solution yet

Word by word:

• encara = still, yet
• no = not

Together, they often express that something has not happened up to now.

Examples:

• Encara no ha arribat. = He/She hasn’t arrived yet.
• Encara no ho sé. = I still don’t know it / I don’t know yet.

Yes — trobar usually means to find, and here trobo means I find.

• trobar = infinitive, to find
• trobo = 1st person singular present, I find

In this sentence, trobar la solució means to find the solution, not to think/opine.

Catalan trobar can also mean to consider / to think, depending on context:

• Trobo que tens raó. = I think you’re right.

But in trobo la solució, the meaning is clearly find.

Yes, in this sentence the definite article la is required:

• la solució = the solution

Catalan uses articles very regularly with nouns, often more consistently than English learners expect.

Here, solució is a specific noun phrase, so la is natural and necessary.
Without the article — trobo solució — it would sound incorrect in standard Catalan.

Also note:

• solució is feminine, so the article is la
• masculine would be el

In Catalan, the normal negative particle no goes directly before the verb:

• no trobo = I do not find / I’m not finding

So:

• encara no trobo la solució

This is standard Catalan word order.
English uses do not find, but Catalan does not need an extra auxiliary like do.

More examples:

• No ho entenc. = I don’t understand it.
• No vull marxar. = I don’t want to leave.

Both are in the present indicative.

• estic = I am
• trobo = I find

Even though English often says I haven’t found the solution yet, Catalan can naturally use the present here:

• encara no trobo la solució

This often conveys a current ongoing situation: up to now, I’m still not finding it.

Catalan could also use other structures in some contexts, but this present-tense version is completely natural.

The original word order is very natural:

• Estic preocupada perquè encara no trobo la solució.

It starts with the main idea (I’m worried) and then gives the reason.

You could rearrange parts of the sentence, but the meaning or emphasis would change. For example:

• Encara no trobo la solució, per això estic preocupada.
  = I still haven’t found the solution, so I’m worried.

Your version:

• Encara no trobo la solució perquè estic preocupada

would more likely mean I still can’t find the solution because I’m worried, which changes the logic. It suggests the worry is the cause of not finding the solution, not the result of it.

So the original sentence is the best way to express I’m worried because I still haven’t found the solution.

A simple pronunciation guide:

• perquè ≈ per-KEH
• solució ≈ soo-loo-see-O

A few details:

• The accent in perquè shows the stress falls on the last syllable: -què
• The accent in solució shows the stress falls on the last syllable: -ció

Very roughly:

• Estic preocupada perquè encara no trobo la solució
• ≈ es-TEEK preh-oh-koo-PAH-dah per-KEH en-KAH-rah no TROH-boh lah soo-loo-see-O

Pronunciation varies somewhat across Catalan dialects, but this is a useful learner-friendly approximation.

Yes. Depending on context, a natural English translation could be:

• I still haven’t found the solution
• I still can’t find the solution
• I haven’t found the solution yet

Catalan present tense often overlaps with several possible English renderings. The exact best translation depends on whether you want to emphasize:

• the result up to now (haven’t found yet), or
• the ongoing difficulty (can’t find)

All of those can fit the Catalan sentence well.

Yes, in many contexts you could.

• preocupada = worried, concerned
• amoïnada = worried, troubled, bothered

So:

• Estic preocupada...
• Estic amoïnada...

Both are possible, though preocupada is very transparent for English speakers and very common.
Depending on region and tone, amoïnada can sound a bit more emotional or idiomatic, while preocupada is straightforward and widely understood.

Here is a helpful breakdown:

• Estic → from estar = to be
• preocupada → from preocupar / preocupat-preocupada = worried / concerned
• perquè = because
• encara = still / yet
• no = not
• trobo → from trobar = to find
• la = the (feminine singular)
• solució = solution

This kind of breakdown is useful because Catalan verbs change form a lot, and recognizing the infinitive helps you learn patterns.
