La meva germana ha de lliurar els apunts a una amiga que està malalta.

In Catalan, possessives are very often used together with the definite article. So la meva germana is the normal way to say my sister.

• la = the
• meva = my
• germana = sister

This is different from English, where you do not say the my sister.

A few family words can sometimes appear without the article in certain contexts, but for learners, article + possessive + noun is the safest and most natural pattern:

• el meu amic = my friend
• la seva mare = his/her mother
• els nostres llibres = our books

Ha de + infinitive is a very common Catalan structure meaning has to, must, or is supposed to.

Here:

• ha = has
• de = to / of in form, but part of the obligation structure here
• lliurar = deliver / hand in / give over

So ha de lliurar means has to deliver or has to hand over.

Similar examples:

• He de marxar. = I have to leave.
• Has d’estudiar. = You have to study.
• Han de venir. = They have to come.

In standard Catalan, obligation is normally expressed with haver de + infinitive:

• he de
• has de
• ha de
• hem de
• heu de
• han de

So ha de lliurar is the standard way to say she has to deliver.

You may sometimes hear other structures in speech, but haver de is the one learners should know and use confidently.

Lliurar can mean to deliver, to hand over, or to hand in, depending on context.

In this sentence, it most naturally means something like:

• to deliver
• to hand over
• to give

Because the object is els apunts and the recipient is una amiga, the idea is that the sister is giving the notes to a friend.

It is a little more formal or specific than just donar in some contexts. Compare:

• donar = to give
• lliurar = to hand over / deliver
• entregar = to deliver / hand in

All can overlap somewhat, but lliurar is perfectly natural here.

Els apunts means the notes, usually class notes or written notes from studying.

• apunt = note
• apunts = notes
• els = the, masculine plural

In Catalan, as in English, notes is often plural when talking about study notes:

• els apunts de classe = class notes
• prendre apunts = to take notes

So lliurar els apunts means to give/deliver the notes.

The preposition a here means to.

So:

• lliurar els apunts a una amiga = to deliver the notes to a friend

Catalan uses a before the recipient of an action, much like English uses to:

• Dono el llibre a la Maria. = I give the book to Maria.
• Explico això a l’alumne. = I explain this to the student.

So una amiga is the person receiving the notes.

In normal interpretation, que està malalta describes una amiga.

So the structure is:

• a una amiga = to a friend
• que està malalta = who is ill

Together:

• a una amiga que està malalta = to a friend who is ill

This is the most natural reading because the relative clause que està malalta comes right after una amiga, so it attaches to that noun.

Grammatically, both germana and amiga are feminine singular, so form alone does not completely disambiguate it. But in ordinary usage, the clause most naturally refers to the nearest suitable noun: amiga.

Catalan, like Spanish, often distinguishes between ser and estar.

Here, estar malalta means to be ill/sick, understood as a state or condition:

• està malalta = she is ill

Using estar is natural because sickness is treated as a temporary or current condition.

So:

• La noia està malalta. = The girl is sick.
• Avui estic malalt. = Today I am sick.

A learner should strongly associate estar + malalt/malalta with to be sick.

Because malalta agrees with a feminine singular noun.

Here it refers to una amiga:

• amic = male friend
• amiga = female friend

So the adjective must also be feminine singular:

• amic malalt = sick male friend
• amiga malalta = sick female friend

Catalan adjectives often change form to match gender and number:

• malalt = masculine singular
• malalta = feminine singular
• malalts = masculine plural
• malaltes = feminine plural

Que is the relative pronoun who, that, or which, depending on context.

In this sentence:

• una amiga que està malalta = a friend who is ill

So que links the noun amiga to extra information about her.

Very common examples:

• la noia que canta = the girl who is singing
• el llibre que llegeixo = the book that I am reading
• els alumnes que estudien = the students who study

The sentence follows a very normal Catalan order:

La meva germana / ha de lliurar / els apunts / a una amiga / que està malalta

That is:

1. Subject: La meva germana
2. Verb phrase: ha de lliurar
3. Direct object: els apunts
4. Indirect object / recipient: a una amiga
5. Relative clause: que està malalta

So the structure is essentially:

My sister + has to deliver + the notes + to a friend + who is ill

This word order is very natural and neutral in Catalan.

Yes. Catalan often replaces direct objects with pronouns.

Since els apunts is masculine plural, the direct object pronoun is els.

So:

• La meva germana ha de lliurar els apunts a una amiga. can become
• La meva germana els ha de lliurar a una amiga.

That means:

• My sister has to deliver them to a friend.

This is useful to know because object pronouns are very common in Catalan, and they often appear before the conjugated verb:

• els ha de lliurar

Even if the meaning is already known, a learner may notice that Catalan often maps onto English a little differently. Natural English translations could be:

• My sister has to give her notes to a friend who is sick.
• My sister has to deliver the notes to a friend who is ill.
• My sister has to hand over the notes to a sick friend.

The Catalan sentence is slightly more explicit in structure, but it is completely natural Catalan.
