La meva filla està pujant la muntanya amb la meva mare.

Està pujant is the Catalan progressive form, built with estar + gerund. It emphasizes that the action is in progress right now:

• està pujant = is climbing / is going up
• puja = climbs / is climbing / goes up, depending on context

So La meva filla està pujant la muntanya sounds more explicitly like something happening at this moment.

Yes. That is also correct.

Catalan often uses the simple present where English might prefer is climbing. So:

• La meva filla puja la muntanya...
• La meva filla està pujant la muntanya...

Both can work. The version with està pujant puts more focus on the ongoing action.

In Catalan, possessives are usually used together with the definite article:

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

This is different from English, where you normally say just my daughter without the. In Catalan, using the article here is standard.

Because Catalan normally combines:

• the definite article: la
• the possessive: meva
• the noun: filla / mare

So the usual pattern is:

• la meva filla
• la meva mare

It may feel redundant to an English speaker, but it is the normal Catalan structure.

Because filla and mare are feminine singular nouns, and the possessive must agree with them.

Catalan possessives change form:

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

So:

• el meu fill = my son
• la meva filla = my daughter
• la meva mare = my mother

Amb means with.

In this sentence, it shows accompaniment:

• amb la meva mare = with my mother

So the idea is that the daughter is going up the mountain together with the speaker’s mother.

Yes, that is the most natural interpretation.

La meva filla està pujant la muntanya amb la meva mare normally means:

• my daughter is climbing the mountain
• and my mother is with her

In other words, they are going up the mountain together.

Because pujar can take a direct object in Catalan.

So:

• pujar la muntanya = climb / go up the mountain

This is normal Catalan. An English speaker might expect something like go up on the mountain or go up the mountain, but in Catalan the direct-object structure is very common with pujar.

The basic order is:

Subject + verb + object + prepositional phrase

So here:

• La meva filla = subject
• està pujant = verb
• la muntanya = object
• amb la meva mare = prepositional phrase

This is a very normal Catalan sentence order.

Yes, but the original order is the most neutral.

For example, you could say:

• Amb la meva mare, la meva filla està pujant la muntanya.

That puts more emphasis on with my mother. But the original sentence is the most straightforward and natural for a basic statement.

It can cover both ideas, depending on context.

In this sentence, pujant la muntanya could be understood as:

• climbing the mountain
• going up the mountain

If the context is hiking or ascending, both are possible translations. Pujar is broader than English climb, and often simply means go up or ascend.

Two sounds often stand out to English speakers:

• ll in filla
• ny in muntanya

Very roughly:

• filla sounds like FEE-ya in many accents
• muntanya sounds roughly like moon-TAN-ya

The ny sound is like the ny in canyon. The exact pronunciation of ll can vary by dialect, but for a beginner, thinking of it as a y-like sound is often a helpful start.
