La porta està trencada, però crec que la podem arreglar avui.

La means the, and porta means door.

In Catalan, nouns usually need an article just as they often do in English. So:

• la porta = the door

Also, porta is a feminine singular noun, so it takes la.

Compare:

• el llibre = the book
• la porta = the door

Catalan often uses estar for a state or condition, especially when something is the result of a change.

So:

• està trencada = is broken / is in a broken state

That sounds natural here because the door is currently in that condition.

Using ser (és) would usually sound less natural in this context. For a learner, a helpful rule is:

• ser = identity, essential characteristic
• estar = condition, state, location

Here the door is not being defined as “a broken kind of door”; it is simply currently broken, so està trencada is the expected choice.

Because trencada agrees with porta, which is feminine singular.

Catalan adjectives and past participle-based adjectives often agree in gender and number with the noun they describe.

Here are the forms:

• trencat = masculine singular
• trencada = feminine singular
• trencats = masculine plural
• trencades = feminine plural

So:

• el vidre està trencat = the glass is broken
• la porta està trencada = the door is broken
• les portes estan trencades = the doors are broken

Here, trencada means broken.

It comes from the verb trencar, meaning to break.

In this sentence, trencada works like an adjective describing the condition of the door.

Examples:

• He trencat el got = I broke the glass
• El got està trencat = The glass is broken

So trencada is related to the action of breaking, but in the sentence it describes the result: the door is in a broken state.

Because Catalan usually uses que to introduce a subordinate clause after verbs like think, believe, say, etc.

So:

• crec que... = I think that...

English often allows you to omit that:

• I think (that) we can fix it

Catalan normally keeps que:

• crec que la podem arreglar

So for learners, it is safest to think:

• crec que = I think that

This la is not the. It is a direct object pronoun meaning it, referring back to la porta.

So:

• La porta està trencada = The door is broken
• la podem arreglar = we can fix it

Because porta is feminine singular, the pronoun is la.

Useful object pronouns include:

• el = him / it (masculine singular)
• la = her / it (feminine singular)
• els = them (masculine plural or mixed)
• les = them (feminine plural)

Yes. In Catalan, object pronouns often go before a conjugated verb, so:

• la podem arreglar = we can fix it

But with an infinitive, Catalan also often allows the pronoun to attach to the infinitive:

• podem arreglar-la

Both are correct and natural.

So these are both possible:

• crec que la podem arreglar avui
• crec que podem arreglar-la avui

For an English speaker, this can feel unusual because English keeps it after the verb, but Catalan clitic pronouns often move before the conjugated verb or attach to an infinitive.

Podem means we can.

It comes from the verb poder, meaning to be able to / can.

Present tense:

• jo puc = I can
• tu pots = you can
• ell/ella pot = he/she can
• nosaltres podem = we can
• vosaltres podeu = you all can
• ells/elles poden = they can

So:

• podem = we can
• poden = they can

The speaker says crec que la podem arreglar because the subject is we.

Arreglar means to fix, to repair, or to sort out, depending on context.

In this sentence:

• arreglar la porta = to fix the door

It is a very common everyday verb. In some contexts, reparar is also possible and can sound a bit more formal or technical.

For example:

• Hem d’arreglar la porta = We need to fix the door
• Han reparat la màquina = They repaired the machine

So arreglar is a natural, common choice here.

Però means but, and it is written with a grave accent: ò.

You simply need to learn this spelling. The accent helps indicate pronunciation and distinguishes the word correctly in standard written Catalan.

So:

• però = but

Do not write pero in standard Catalan.

Because Catalan often places time expressions like avui (today) at the end, especially in neutral word order.

So:

• la podem arreglar avui = we can fix it today

That said, Catalan is fairly flexible, and you could also say:

• avui la podem arreglar
• crec que avui la podem arreglar

Moving avui changes the emphasis slightly:

• avui la podem arreglar emphasizes today
• la podem arreglar avui sounds neutral and natural

The sentence has two parts joined by però (but):

1. La porta està trencada

   • La porta = the door
   • està = is
   • trencada = broken

2. però crec que la podem arreglar avui

   • però = but
   • crec = I think
   • que = that
   • la = it
   • podem = we can
   • arreglar = fix
   • avui = today

So the structure is roughly:

• Statement 1: The door is broken
• Connector: but
• Statement 2: I think that we can fix it today

A simple learner-friendly pronunciation guide is:

la POR-ta es-TA tren-KA-da, pe-RO KREK ke la po-DEM a-rre-GLAR a-VUI

A few notes:

• ll does not appear here, so that common Catalan sound is not an issue in this sentence.
• r in però, crec, and arreglar may sound stronger or tapped depending on position and speaker.
• avui is roughly like ah-VOO-ee.
• crec is pronounced with a final k sound.

This is only an approximation, but it can help you say the sentence more confidently.
