La parada de metro és a prop, així que les convidades no arribaran tard.

In Catalan, when one noun describes another, you very often link them with de.

So:

• parada de metro = metro stop
• literally, stop of metro

This is much more natural in Catalan than stacking nouns the way English often does.

A few similar examples:

• estació de tren = train station
• taula de fusta = wooden table
• sabates de cuir = leather shoes

So la parada de metro is the normal Catalan structure.

The noun parada is feminine, so it takes the feminine singular article la.

• la parada = the stop

A lot of Catalan nouns ending in -a are feminine, and parada follows that common pattern.

Compare:

• la parada
• la casa
• la porta

But remember: endings help, though they are not a perfect rule for every word in the language.

A prop means near, nearby, or close.

In this sentence:

• és a prop = is nearby / is close

It is a fixed expression. You should learn it as a chunk:

• a prop = near
• a prop de = near / close to

Examples:

• L’escola és a prop. = The school is nearby.
• L’escola és a prop de casa. = The school is near home.

So in your sentence, La parada de metro és a prop means the metro stop is close by.

És is the 3rd person singular of the verb ser:

• és = is

The accent matters because it distinguishes it from es, which is a pronoun.

Compare:

• és = is
• es = himself/herself/itself, or part of a pronominal/passive structure

Example:

• La parada és a prop. = The stop is nearby.
• Es diu Marta. = She is called Marta.

So the accent is not optional here.

Yes, in this sentence així que means so or therefore.

• La parada de metro és a prop, així que...
• The metro stop is nearby, so...

It links a cause and a result.

You can think of it as:

• because this is true, the following result makes sense

Other connectors you may also see are:

• per això = for that reason / that’s why
• doncs = so / then / well, then

But així que is a very natural choice here.

Grammatically, convidades is the feminine plural form of convidat/convidada.

• la convidada = the invited woman / female guest
• les convidades = the invited women / female guests

So yes, taken literally, les convidades refers to a group of women.

If the group were masculine or mixed, standard Catalan would usually use:

• els convidats

Depending on context, a speaker may choose the feminine intentionally if the group is female or for stylistic/social reasons. But the basic grammar point is:

• les
  • feminine plural noun
• convidades = feminine plural adjective/noun form

It functions like a noun here, even though it comes from a participle/adjectival form.

Literally, it means something like:

• the invited ones
• more naturally: the guests

So in this sentence:

• les convidades = the invited women / the female guests

Catalan often uses article + adjective/participle this way, just like English can sometimes say the rich, the injured, etc.

Because in Catalan, standard negation puts no directly before the conjugated verb.

So:

• arribaran = they will arrive
• no arribaran = they will not arrive

This is the normal pattern:

• No ve. = He/She isn’t coming.
• No ho sé. = I don’t know it / I don’t know.
• No arribaran tard. = They won’t arrive late.

For an English speaker, this is important because Catalan does not usually build negation with a separate helping verb like do.

Arribaran is the future tense, 3rd person plural, of arribar:

• arribar = to arrive
• arribaran = they will arrive

The sentence says:

• les convidades no arribaran tard
• the guests won’t arrive late

The future in Catalan is often formed by adding endings directly to the infinitive:

• arribaré = I will arrive
• arribaràs = you will arrive
• arribarà = he/she will arrive
• arribarem = we will arrive
• arribareu = you all will arrive
• arribaran = they will arrive

Yes, sometimes Catalan can use the present to talk about the near future, just like English can.

For example:

• Les convidades no arriben tard.

Depending on context, that could mean something like The guests aren’t arriving late or The guests won’t be late.

But no arribaran tard is clearer and more explicitly future-oriented. It strongly matches won’t arrive late.

Because tard here is an adverb, meaning late.

• arribar tard = to arrive late

It does not change for gender or number.

Examples:

• Arribo tard. = I arrive late / I’m late.
• Arriben tard. = They arrive late.
• Les convidades no arribaran tard. = The guests won’t arrive late.

Do not confuse it with tarda, which is a noun meaning afternoon.

• la tarda = the afternoon

So:

• tard = late
• tarda = afternoon

Catalan word order is fairly flexible, though the version in your sentence is the most neutral.

Neutral order:

• les convidades no arribaran tard

You can sometimes place the subject after the verb, especially for emphasis or style:

• No arribaran tard, les convidades.

But that sounds more marked, not the basic everyday order.

For learners, the safest default is:

• subject + no + verb + other elements

So the sentence as given is the most straightforward way to say it.

A good learner-friendly approximation is:

• així ≈ eye-SHEE

A few notes:

• the x in així sounds like sh
• the stress is on the last syllable because of the accent: -sí

So:

• així → eye-SHEE

And in així que, you would say something like:

• eye-SHEE kuh

Yes. A prop can appear in two common ways:

1. a prop = nearby
2. a prop de + noun/place = near / close to something

Examples:

• La parada és a prop. = The stop is nearby.
• La parada és a prop de l’hotel. = The stop is near the hotel.

In your sentence, there is no specific reference point after it, so just a prop is enough.

Not in this sentence, because the subject is singular:

• La parada = singular
• so the verb must be singular: és

If the subject were plural, then you would use estan:

• Les parades són a prop. = The stops are nearby.

Also note that with a prop, Catalan normally uses ser here:

• és a prop
• són a prop

So for this sentence, és a prop is correct.
