Demà hem d'acabar l'informe perquè una clienta el vol llegir abans de la reunió.

Hem d'acabar is the Catalan way to say we have to finish or we must finish.

It is built like this:

• hem = we have
• de = to
• acabar = finish

So the pattern is:

haver + de + infinitive = to have to do something

Examples:

• He de marxar = I have to leave
• Has d'estudiar = You have to study
• Hem d'acabar = We have to finish

In this sentence, hem is the 1st person plural form of haver.

This is because de becomes d' before a word beginning with a vowel.

So:

• de + acabar → d'acabar

This is very common in Catalan and works much like elision in French.

More examples:

• d'anar
• d'estudiar
• d'obrir

It is just a spelling and pronunciation change for smoother speech; the meaning stays the same.

The masculine singular definite article is normally el, but before a vowel it usually becomes l'.

So:

• el informe → l'informe

This is the same article, just in its elided form.

Examples:

• el llibre = the book
• l'informe = the report
• l'home = the man

So l'informe simply means the report.

That el is a direct object pronoun meaning it.

It refers back to l'informe:

• l'informe = the report
• el = it

So:

• una clienta el vol llegir = a client wants to read it

Catalan often uses object pronouns where English uses it, him, her, them, etc.

Here the pronoun is masculine singular because informe is masculine singular.

In Catalan, object pronouns usually go before a conjugated verb.

So:

• el vol llegir = literally, it wants to read

This sounds strange in English word-for-word, but in Catalan it means:

• wants to read it

With a verb + infinitive structure, the object pronoun can often go:

1. before the conjugated verb
   
   • el vol llegir

and sometimes also

2. attached to the infinitive
   
   • vol llegir-lo

Both can be correct, but el vol llegir is very natural and common.

Yes, that is also possible.

Both of these can mean a client wants to read it:

• una clienta el vol llegir
• una clienta vol llegir-lo

The difference is mainly one of placement of the object pronoun:

• el vol llegir → pronoun before the conjugated verb
• vol llegir-lo → pronoun attached to the infinitive

Both are normal Catalan. In many contexts, speakers may prefer one or the other stylistically, but both are grammatical.

Here perquè means because.

So this part:

• perquè una clienta el vol llegir
  means
• because a client wants to read it

This is a very common word, but learners often confuse it with similar forms:

• perquè = because
• per què = why / for what
• el perquè = the reason

Examples:

• No vinc perquè estic cansat = I'm not coming because I'm tired
• Per què no vens? = Why aren't you coming?

In your sentence, it introduces the reason, so perquè is the correct form.

Yes. Clienta is the feminine form, so it means a female client.

• un client = a male client / a client
• una clienta = a female client

Catalan nouns often show gender clearly, and the article must match:

• un with masculine nouns
• una with feminine nouns

So una clienta tells you explicitly that the client is female.

Because la reunió is a noun phrase, not a full clause.

Catalan uses:

• abans de + noun / infinitive
• abans que + clause

So here:

• abans de la reunió = before the meeting

Examples:

• abans de dinar = before lunch / before eating
• abans de la reunió = before the meeting
• abans que arribi = before he/she arrives

Since la reunió is a noun, de is the right choice.

Catalan word order is fairly flexible, although some orders sound more natural than others.

Demà at the beginning is very natural because it sets the time right away:

• Demà hem d'acabar l'informe...

You could also hear:

• Hem d'acabar l'informe demà...

Both are possible, but the emphasis changes slightly:

• Demà... emphasizes tomorrow
• Hem d'acabar l'informe demà... sounds a bit more neutral or places the time later

Starting with Demà is very common when the speaker wants to frame the whole sentence in time from the start.

Reunió means meeting and it is a feminine noun.

So:

• una reunió = a meeting
• la reunió = the meeting

That is why the sentence says:

• abans de la reunió = before the meeting

The ending -ió often appears in feminine nouns in Catalan, though learners should still learn noun gender individually when needed.

A careful pronunciation guide would be roughly:

Demà hem d'acabar l'informe perquè una clienta el vol llegir abans de la reunió

Approximate pronunciation: deh-MA em da-ka-BAR lin-FOR-muh per-KE oo-nuh kli-EN-tuh ul VOL luh-ZHIR uh-BANS duh luh ray-oo-nee-O

A few useful points:

• Demà is stressed on the last syllable: de-MÀ
• d'acabar is said smoothly, almost as one unit
• l'informe also links smoothly
• perquè is stressed on the last syllable: per-QUÈ
• llegir has the ll sound typical of Catalan; depending on accent, it may sound a bit like ly or a softer j/y sound
• reunió is stressed on the last syllable: re-u-ni-Ó

Exact pronunciation varies by dialect, but these stress patterns are important in all varieties.
