A l'octubre, quan comença la tardor, la meva mare guarda la roba d'estiu.

In Catalan, months are often introduced with a in time expressions, where English uses in. Also, month names normally take the definite article: el gener, el març, l'abril, l'octubre.

So:

• a + l'octubre = in October

Because octubre begins with a vowel, the article is l', giving A l'octubre.

That part is an inserted time clause: when autumn begins. The commas show it is extra information placed between the opening time phrase and the main clause.

Structure:

• A l'octubre = time setting
• quan comença la tardor = extra time-related clause
• la meva mare guarda la roba d'estiu = main statement

The commas help the sentence read naturally and make the structure clear.

Quan means when. It introduces a subordinate clause of time.

So:

• quan comença la tardor = when autumn begins

It works much like English when in a sentence such as When autumn begins, my mother puts away the summer clothes.

Catalan often uses the present tense for things that happen regularly or are generally true. This sentence describes a habitual seasonal action, not one single event happening right now.

So comença means begins in a general, recurring sense:

• quan comença la tardor = when autumn begins / when autumn starts

This is very natural in Catalan.

The ç keeps the s sound before a, o, or u.

Without it, c before a would sound like k. So:

• comença is pronounced with an s sound
• the spelling comes from the verb començar = to begin

This is a normal spelling pattern in Catalan.

Catalan usually uses the definite article with a possessive:

• la meva mare = my mother
• el meu pare = my father

This is different from English, which normally uses only my without the. In standard Catalan, the article is usually expected in neutral statements like this one.

The possessive has to agree with the noun it goes with.

• mare is feminine singular
• so the possessive must also be feminine singular: meva

Compare:

• la meva mare = my mother
• el meu pare = my father

So meva matches mare.

The basic verb guardar can mean to keep, to store, to put away, or to save, depending on context.

In this sentence, the most natural meaning is:

• puts away
• stores

So la meva mare guarda la roba d'estiu means she puts the summer clothes away for the season.

In Catalan, roba is usually a singular collective noun meaning clothing or clothes.

So:

• la roba = clothes / clothing

Even though English often uses the plural clothes, Catalan normally uses singular roba for the general idea.

Here d'estiu means summer in the sense of summer clothes: clothes for the summer season.

Two things are happening:

1. de becomes d' before a vowel:

   • de estiu → d'estiu

2. No article is used because this is a general category:

   • roba d'estiu = summer clothes

If you said de l'estiu, it would sound more like of the summer, referring to a specific summer rather than the general type of clothes.

Yes. Catalan has some flexibility in word order, especially with time expressions.

This sentence begins with the time phrase for emphasis or scene-setting:

• A l'octubre, quan comença la tardor, ...

You could also say:

• La meva mare guarda la roba d'estiu a l'octubre, quan comença la tardor.

Both are understandable, but the original version sounds very natural because it starts by placing the action in time.
