El propietari arregla l'avaria avui.

El is the masculine singular definite article, equivalent to English the. It shows that we are talking about a specific owner, not just any owner.

• el propietari = the owner
• un propietari = an owner

Because Catalan usually shortens la to l' before a word that begins with a vowel or silent h.

So:

• la + avaria becomes l'avaria

This is called elision. The apostrophe shows that the a of la has been dropped.

Catalan often leaves subject pronouns out because the verb ending already tells you who the subject is.

Here, arregla is the third person singular form, so it already means something like he fixes, she fixes, or it fixes, depending on context.

So Catalan can say:

• El propietari arregla l'avaria avui

without needing an extra pronoun like ell.

Arregla is the present indicative, third person singular, of the verb arreglar.

The infinitive is:

• arreglar = to fix / to repair

Some present-tense forms are:

• arreglo = I fix
• arregles = you fix
• arregla = he/she fixes
• arreglem = we fix
• arreglen = they fix

It can often cover both, depending on context.

Catalan uses the simple present more broadly than English does. So arregla may be understood as:

• fixes
• is fixing

If you want to make the ongoing action more explicit, Catalan can also use:

• està arreglant

So a more explicitly progressive version would be:

• El propietari està arreglant l'avaria avui

But the original sentence is completely natural.

Yes, avui can move. Catalan word order is fairly flexible, especially with time expressions.

All of these are possible:

• El propietari arregla l'avaria avui
• Avui el propietari arregla l'avaria
• El propietari avui arregla l'avaria

Putting avui at the end is very natural and neutral. Moving it to the beginning often gives it a bit more emphasis.

Avaria usually means a fault, breakdown, or malfunction, especially with something mechanical, electrical, or technical.

It is more specific than a general word like problema.

For example, avaria is a good word for:

• a machine fault
• a car breakdown
• an electrical failure
• a plumbing issue

So it often suggests that something is not working properly and needs repair.

You would use the feminine form:

• La propietària arregla l'avaria avui

Changes:

• El becomes La
• propietari becomes propietària

Notice the written accent in propietària.

Yes. You can replace it with the feminine singular direct object pronoun la, which becomes l' before a vowel.

So:

• El propietari arregla l'avaria avui
• El propietari l'arregla avui

Here l' means it, referring to l'avaria.

Yes. Both arreglar and reparar can work.

• arreglar is very common in everyday speech
• reparar can sound a bit more technical or formal

So this is also correct:

• El propietari repara l'avaria avui

But arregla is very natural and common.

A rough pronunciation guide is:

• El propietari arregla l'avaria avui
• el pro-pyə-TA-ri a-RRE-gla la-va-RI-a a-VUI

A few helpful points:

• propietari is stressed on ta
• arregla is stressed on rre
• avaria is stressed on ri
• avui is stressed on the second syllable

The exact pronunciation varies by dialect, but this stress pattern will help a lot.
