La mare es desperta tard diumenge perquè dissabte treballa.

In Catalan, it is very common to use the definite article before close family members when you are talking about them, especially when it is already clear whose family member you mean.

So:

• la mare = mother / mum
• el pare = father / dad

This often sounds natural where English would use my mother or my mum.

For example:

• La mare treballa molt. = Mum works a lot.
• El pare arriba tard. = Dad arrives late.

You usually leave out the article when directly addressing the person:

• Mare, vine! = Mum, come here!

Es desperta comes from the reflexive verb despertar-se, which means to wake up.

The es is the reflexive pronoun for he/she/it.

So:

• despertar = to wake someone/something
• despertar-se = to wake up

Compare:

• La mare es desperta tard. = Mother wakes up late.
• La mare desperta el nen. = Mother wakes the child up.

That little es is important, because without it the meaning changes.

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

• treballa = he/she works

Since the subject is still la mare, Catalan does not need to repeat ella.

So:

• dissabte treballa = on Saturday she works

You could say ella treballa, but that usually adds emphasis or contrast:

• Ella treballa, però jo no. = She works, but I don’t.

Because that is the normal position in Catalan here.

• es desperta tard = wakes up late

Catalan often places adverbs like tard after the verb in neutral word order.

This is very natural:

• arriba tard = arrives late
• menja ràpid = eats quickly
• es desperta tard = wakes up late

You can move words around for emphasis, but the version in the sentence is the most straightforward one.

Catalan often does not use a preposition before days of the week when they function as time expressions.

So English:

• on Sunday
• on Saturday

often becomes simply:

• diumenge
• dissabte

That is why you get:

• diumenge = on Sunday
• dissabte treballa = she works on Saturday

This is very normal Catalan.

This is a very good question, because Catalan can be a bit subtle here.

As written, diumenge and dissabte without articles often suggest a specific Sunday and Saturday, depending on context.

If you want to make a habitual meaning clearer, Catalan often uses:

• els diumenges = on Sundays
• els dissabtes = on Saturdays

So if the meaning is habitual, many speakers would say:

• La mare es desperta tard els diumenges perquè els dissabtes treballa.

That makes the repeated pattern much clearer: she wakes up late on Sundays because she works on Saturdays.

Perquè means because.

It is written as one word and has an accent to distinguish it from other similar forms.

Important contrast:

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

Examples:

• Treballa perquè necessita diners. = She works because she needs money.
• Per què treballa dissabte? = Why does she work on Saturday?

So in your sentence, perquè introduces the reason.

Catalan uses the present tense for things like:

• habits
• routines
• general facts
• sometimes near or relevant situations, depending on context

So:

• es desperta
• treballa

can describe a regular pattern:

• She wakes up late on Sunday because she works on Saturday.

If you wanted to talk clearly about a past situation, Catalan would normally use a different tense.

Yes. Catalan word order is flexible, although some versions sound more neutral than others.

The given sentence is perfectly understandable, but you could also say:

• Diumenge la mare es desperta tard perquè dissabte treballa.

Putting diumenge first gives a little more focus to the time.

The basic meaning stays the same, but the emphasis changes slightly. Catalan often moves time expressions to the front when the speaker wants to frame the sentence around when something happens.
