El reemborsament arribarà, per descomptat.

El is the masculine singular definite article in Catalan, equivalent to the in English.

So:

• el reemborsament = the refund

The noun reemborsament is masculine singular, so it takes el.

Other forms of the article are:

• el = masculine singular
• la = feminine singular
• els = masculine plural
• les = feminine plural

For example:

• el reemborsament
• la devolució
• els reemborsaments

Reemborsament is a noun meaning refund or reimbursement.

It comes from the verb reemborsar, meaning to reimburse or to refund.

A useful pattern in Catalan is:

• -ar verb → -ament noun

So:

• reemborsar = to refund / reimburse
• reemborsament = refund / reimbursement

You may also see devolució in Catalan, which can also mean refund, especially in shopping contexts. Depending on context, both can be natural, but reemborsament sounds a bit more formal or administrative.

Arribarà is the 3rd person singular future of the verb arribar, meaning to arrive.

So:

• arribar = to arrive
• arribarà = he/she/it will arrive

In this sentence, the subject is el reemborsament, so arribarà means:

• the refund will arrive

This future form is built from the infinitive plus a future ending:

• arribar
  • -à → arribarà

Some other future forms of arribar:

• arribaré = I will arrive
• arribaràs = you will arrive
• arribarà = he/she/it will arrive
• arribarem = we will arrive
• arribareu = you all will arrive
• arribaran = they will arrive

Catalan often uses arribar with things like money, payments, emails, letters, packages, and refunds in a very natural way.

So El reemborsament arribarà literally means The refund will arrive, and this is a normal Catalan way to express the idea.

Depending on context, Catalan could also say things like:

• Rebràs el reemborsament = You will receive the refund
• El reemborsament es farà aviat = The refund will be processed / made soon

But arribarà sounds completely natural if the idea is that the refund is on its way or will come through.

Per descomptat means of course, certainly, or naturally.

Even though descompte means discount, in the expression per descomptat the meaning is idiomatic. You should learn it as a fixed phrase meaning of course.

So:

• per descomptat = of course

It is very common and useful in conversation.

Similar expressions include:

• és clar = of course / obviously
• naturalment = naturally
• evidentment = evidently / obviously

The commas show that per descomptat is being used as a parenthetical expression, like an aside.

So the structure is:

• El reemborsament arribarà, per descomptat.

This feels like:

• The refund will arrive, of course.

The commas help separate the main statement from the speaker’s comment.

You could also put the phrase in other positions:

• Per descomptat, el reemborsament arribarà.
• El reemborsament, per descomptat, arribarà.

All of these are possible, though the original sentence sounds very natural.

Yes. Catalan allows some flexibility with adverbs and discourse expressions like per descomptat.

For example:

• Per descomptat, el reemborsament arribarà.
• El reemborsament arribarà, per descomptat.

The meaning is basically the same, but the emphasis changes slightly:

• Per descomptat, ... puts the of course idea first
• ..., per descomptat adds it after the main statement, almost like reassurance

In Catalan, the future tense can sometimes express probability or supposition, but in this sentence it is most naturally read as a real future:

• El reemborsament arribarà = The refund will arrive

So here it means the refund is expected to come later.

A probabilistic future would usually depend more on context. For example, in another situation, Serà a casa could mean He’s probably at home. But arribarà here is most naturally just future time.

A rough pronunciation guide for English speakers:

• arribarà ≈ ah-ree-bah-RAH
• reemborsament ≈ ray-um-bur-suh-MENT or reh-em-bur-suh-MENT, depending on accent and speed
• per descomptat ≈ pair dəs-komp-TAT

A few useful notes:

• The final accented à in arribarà tells you the stress falls on the last syllable.
• Catalan r is not the English r. A single r between vowels is usually a tap.
• In normal speech, unstressed vowels may sound more reduced than an English speaker expects.

If you want the most important stress points:

• reemborsament
• arribarà
• descomptat

The accent mark in arribarà shows where the stress goes:

• arri-ba-rà

Without the accent, the word would not follow normal Catalan spelling rules for that pronunciation.

In this case, the accent is important because it marks the future ending -à and helps distinguish the pronunciation clearly.

Many future forms in Catalan have written accents:

• arribarà
• tindrà
• farà
• podrà

So yes, the accent is essential and should be written.

Usually arribarà is the more natural choice here.

Both arribar and venir can sometimes overlap in English as come/arrive, but with something like a refund, arribar fits better:

• El reemborsament arribarà = natural
• El reemborsament vindrà = less natural in this context

Catalan often uses arribar for things that are delivered, received, or processed over time, especially abstract things like payments, refunds, or notices.

You would need to change both the noun and the verb:

• El reemborsament arribarà = The refund will arrive
• Els reemborsaments arribaran = The refunds will arrive

Changes:

• el → els
• reemborsament → reemborsaments
• arribarà → arribaran

So the verb must agree with the subject in number.
