La meva companya de feina m'ha enviat un missatge perquè avui arribarà tard.

In Catalan, possessives usually come with the definite article:

• la meva companya
• el meu amic
• les seves claus

So la meva is the normal way to say my with a feminine singular noun.

This is different from English, where you just say my coworker without the.

Companya means female companion / colleague / coworker, and de feina means from work or for work in the sense of work-related.

So la meva companya de feina means:

• my female coworker
• my colleague at work

If the coworker were male, it would be company de feina.

A very similar alternative is companya de treball.

M' is the shortened form of em, the unstressed pronoun meaning to me.

So:

• em ha enviat → m'ha enviat

This shortening happens before a vowel or silent h.

So m'ha enviat un missatge means has sent me a message.

You can think of the structure like this:

• m' = to me
• ha enviat = has sent

Ha enviat is the present perfect:

• ha = has
• enviat = past participle of enviar

So m'ha enviat literally corresponds to has sent me.

In Catalan, this tense is often used for a completed action connected to the present, especially something that happened recently or within the current time frame.

Yes. Missatge is the standard Catalan word for message.

So:

• enviar un missatge = to send a message

Depending on context, it can mean:

• a text message
• a message in an app
• a general message

If you specifically wanted text message, speakers may also say SMS or just rely on context.

Here perquè means because.

The accent matters. Catalan distinguishes between:

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

So in this sentence, perquè introduces the reason:

• She sent me a message because today she’ll arrive late.

This is a very common point of confusion for learners.

Yes. Arribarà is the simple future of arribar:

• arribarà = she/he will arrive

In this sentence, it means she will arrive late later today.

Catalan often uses the future in exactly this kind of situation, where English might also say:

• she will arrive late
• she’ll be late
• sometimes even she’s arriving late today, depending on context

So avui arribarà tard is perfectly natural.

Avui means today, and its position here is very natural.

• perquè avui arribarà tard

Placing avui before the verb helps frame the time first: because today she’ll arrive late.

Other word orders are possible, but this one is especially normal and clear.

Yes, tard here is the adverb late.

So:

• arribar tard = to arrive late

Do not confuse it with tarda, which means afternoon.

Compare:

• arribarà tard = she will arrive late
• a la tarda = in the afternoon

That difference is very important.

Yes, it is very natural.

The structure is:

• La meva companya de feina = subject
• m'ha enviat un missatge = main clause
• perquè avui arribarà tard = reason clause

So Catalan is basically saying:

• My coworker has sent me a message because today she’ll arrive late

This is a very standard and idiomatic sentence.

Yes, in some contexts speakers may use the present:

• avui arriba tard

That can also sound natural, especially in everyday speech when talking about something scheduled or already known.

But arribarà tard is also completely correct and perhaps slightly more explicit about the future result.

So both can work, depending on nuance and speaker preference.

Absolutely. It is a very useful pattern.

You can replace different parts:

• M'ha enviat un correu = She/He sent me an email
• M'ha enviat una foto = She/He sent me a photo
• M'ha enviat això = She/He sent me this

And with other pronouns:

• T'ha enviat un missatge = She/He sent you a message
• Li ha enviat un missatge = She/He sent him/her a message
• Ens ha enviat un missatge = She/He sent us a message

So this sentence is a great model for learning Catalan pronouns and the present perfect.
