La meva mare encara guarda els meus quaderns i alguns resums de l'escola.

Because standard Catalan normally uses the definite article + possessive together:

• la meva mare = my mother
• els meus quaderns = my notebooks

This is one of the most noticeable differences from English. In ordinary Catalan, meva mare or meus quaderns without the article would usually sound incomplete, literary, or limited to special contexts.

So:

• la meva mare is the normal way to say my mother
• els meus quaderns is the normal way to say my notebooks

The possessive has to agree with the noun being possessed, not with the owner.

Here are the forms used in the sentence:

• mare is feminine singular → meva
• quaderns is masculine plural → meus

So:

• la meva mare
• els meus quaderns

Common forms of meu are:

• meu = masculine singular
• meva = feminine singular
• meus = masculine plural
• meves = feminine plural

Here encara means still.

So La meva mare encara guarda... means My mother still keeps...

It shows that the action continues up to now. In other contexts, encara can also mean things like yet or even, but in this sentence still is the natural meaning.

That is a very natural position in Catalan. Adverbs like encara often go before the verb:

• encara guarda = still keeps
• encara viu = still lives
• encara treballa = still works

You may also hear slightly different word orders for emphasis, but encara guarda is the normal, neutral order.

Guarda is the 3rd person singular present indicative of guardar.

• guardar = to keep, to store, to save
• guarda = he/she/it keeps

In this sentence it means she keeps or she still has.

Because Catalan often leaves out subject pronouns, you do not need ella. The verb form guarda already tells you it is he/she.

It can mean all of those depending on context.

In this sentence, guarda suggests something like:

• keeps
• has kept
• stores
• holds on to

So La meva mare encara guarda els meus quaderns... means that she has not thrown them away and still has them.

Because alguns already works as a determiner meaning some.

Compare:

• els meus quaderns = my notebooks
• alguns resums = some summaries

You normally do not add a definite article before alguns in this kind of phrase.

So:

• els meus quaderns = a specific set: my notebooks
• alguns resums = an indefinite quantity: some summaries

Yes, quaderns usually means notebooks or exercise books.

Singular:

• quadern = notebook

Plural:

• quaderns = notebooks

In a school context, quaderns often refers to the notebooks a student wrote in for classwork.

Resums is the plural of resum, which means summary.

In a school context, resums can mean:

• summaries
• outlines
• condensed notes

So alguns resums de l'escola is something like some school summaries/notes.

Here it most naturally means from school or school-related.

So:

• alguns resums de l'escola = some summaries from school / some school summaries

In context, it refers to materials connected with school. English often prefers a looser translation rather than a word-for-word one.

Because the article la becomes l' before a vowel sound.

So:

• la escola → l'escola

This is just normal apostrophe use in Catalan.

And after de, you get:

• de + l'escola = de l'escola

Grammatically, it most directly attaches to alguns resums:

• els meus quaderns i alguns resums de l'escola

So the most immediate reading is:

• my notebooks and some summaries from school

That said, from the real-world meaning, the whole sentence is clearly about old school materials, so listeners may understand the school connection more broadly.

Catalan is a pro-drop language, which means subject pronouns are often omitted when the verb already makes the person clear.

So instead of saying:

• Ella guarda...

Catalan very naturally says:

• Guarda...

In this sentence, guarda already tells us it is he/she in the singular, and la meva mare makes it clear that it is she.
