La meva mare diu que la carnisseria que és prop de l'estació té carn i ous.

In Catalan, it is very common to use the definite article with family members and possessives:

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

This is different from English, which normally does not use the in phrases like my mother.

So:

• la meva mare diu... literally looks like the my mother says...
• but the natural English meaning is simply my mother says...

This article is especially common in standard Catalan with singular family nouns.

diu means says, from the verb dir = to say.

que here means that and introduces the content of what is being said:

• La meva mare diu que...
• My mother says that...

In English, that is often optional:

• My mother says the butcher’s shop...
• My mother says that the butcher’s shop...

In Catalan, que is normally kept.

They do two different jobs.

1. diu que
   Here que means that and introduces a clause:

   • My mother says that...

2. la carnisseria que és prop de l'estació
   Here que is a relative pronoun, meaning that/which:

   • the butcher’s shop that is near the station

So the sentence has:

• one que = that after diu
• one que = that/which after carnisseria

carnisseria means butcher’s shop or butcher shop.

It comes from:

• carn = meat
• carnisser / carnissera = butcher
• carnisseria = butcher’s shop

So la carnisseria is the place where meat is sold.

Because it describes which butcher’s shop we are talking about.

• la carnisseria = the butcher’s shop
• que és prop de l'estació = that is near the station

Together:

• la carnisseria que és prop de l'estació
• the butcher’s shop that is near the station

This relative clause directly modifies la carnisseria, not la meva mare.

prop de means near or close to.

Examples:

• prop de l'estació = near the station
• prop de casa = near home

A useful thing to remember is that prop normally goes with de before the noun:

• prop de l'escola
• prop del mercat

You may also see a prop de, which is also very common:

• és a prop de l'estació = it is near the station

Because Catalan usually contracts or elides the article before a vowel.

• la estació becomes l'estació
• so de + l'estació = de l'estació

This is similar to how Catalan writes:

• l'escola
• l'home
• l'amiga

So:

• prop de l'estació = near the station

Because estació is a feminine noun in Catalan, so it takes feminine articles:

• l'estació
• una estació
• aquesta estació

You simply have to learn the gender of nouns as part of the word. In this case:

• estació = feminine

té is the he/she/it form of tenir (to have):

• jo tinc = I have
• tu tens = you have
• ell/ella té = he/she/it has

The accent is important because it distinguishes té from te.

Here:

• la carnisseria ... té carn i ous
• the butcher’s shop ... has meat and eggs

In Catalan, when talking about things in a general or indefinite way, nouns often appear without an article.

So:

• té carn i ous = it has meat and eggs

This sounds natural in Catalan. English does something similar here too:

• we say it has meat and eggs, not usually it has the meat and the eggs

If the sentence were referring to specific meat or specific eggs, the wording might be different.

ous is plural.

• ou = egg
• ous = eggs

So:

• carn i ous = meat and eggs

A learner may notice that ou becomes ous, not something like ousos or another pattern. It is just the normal plural form of this noun.

Because of the structure of the sentence.

The main subject of the embedded clause is:

• la carnisseria ... té carn i ous

The part que és prop de l'estació is just extra information describing la carnisseria.

So the structure is:

• La meva mare diu
• [que [la carnisseria [que és prop de l'estació]] té carn i ous]

That means:

• the butcher’s shop is near the station
• and the butcher’s shop has meat and eggs

Not:

• the station has meat and eggs

Yes, you may hear both, depending on style and context.

• és prop de = is near
• està prop de = also is near

In many real-life contexts, estar is very common for location:

• La carnisseria està prop de l'estació

But és prop de is also understandable and acceptable in many contexts. For a learner, the key point is that prop de means near, whether the verb used is és or està.

Not quite. A close word-for-word breakdown is:

• La meva mare = the my mother
• diu = says
• que = that
• la carnisseria = the butcher’s shop
• que = that/which
• és prop de = is near
• l'estació = the station
• té = has
• carn i ous = meat and eggs

Natural English:

• My mother says that the butcher’s shop near the station has meat and eggs.

So the meaning matches well, but the grammar is not identical in every detail.
