Hi ha prou xocolata per a tothom? Sí, n'hi ha, però del pastís no en quedarà gaire.

Hi ha is the standard Catalan way to say there is or there are.

It comes from the verb haver-hi, an existential expression. In this use, it does not mean to have in the normal possession sense.

So:

• Hi ha prou xocolata? = Is there enough chocolate?
• not a structure with ser or estar

The hi is part of this fixed existential construction.

Prou means enough.

So prou xocolata means enough chocolate or sufficient chocolate.

It is different from:

• molt / molta = a lot of
• gaire = much/many, usually in negative or question contexts

So:

• prou xocolata = enough chocolate
• molta xocolata = a lot of chocolate

Those are not exactly the same idea.

After a quantity word like prou, Catalan normally uses the noun directly, without an article.

So you say:

• prou xocolata
• prou aigua
• prou diners

not usually la xocolata in this kind of general quantity expression.

This is very natural in Catalan and works much like English enough chocolate, not enough the chocolate.

Per a tothom means for everyone.

• tothom = everyone / everybody
• per a = for

So Hi ha prou xocolata per a tothom? is literally Is there enough chocolate for everyone?

In formal or careful Catalan, per a is often used to mean for, especially when talking about a destination, recipient, or intended purpose.

So per a tothom = for everyone.

In everyday speech, many speakers often just say per instead of per a, especially in some dialects. So you may also hear:

• per tothom

Both are common, but per a tothom is perfectly standard.

Because Catalan uses en when referring back to an unspecified quantity of something, especially with mass nouns like xocolata.

Here, n' stands for something like of it / some.

So:

• Hi ha xocolata? = Is there chocolate?
• Sí, n'hi ha. = Yes, there is some.

If you say only Sí, that is possible as a short answer. But Sí, n'hi ha is fuller and explicitly refers back to the chocolate.

They do different jobs:

• en → n' before a vowel or mute h; it refers to some of it / of that
• hi → part of the existential structure haver-hi, meaning there is/are

So n'hi ha is roughly:

• there is some (of it)
• literally something like of-it there-is

English does not build the sentence this way, but Catalan very often does.

The pronoun en becomes n' before a word beginning with a vowel or silent h.

Since the next word is hi, it becomes:

• en hi ha → n'hi ha

This is just the normal written form.

You will see the same thing in other cases too, for example:

• N'he vist tres = I’ve seen three of them

Del is the contraction of de + el, so del pastís means of the cake or, in context, as for the cake.

Here it introduces the topic: the speaker shifts from chocolate to cake.

So the structure is roughly:

• But as for the cake, there won’t be much of it left

Starting with del pastís gives it topical emphasis.

That en refers back to pastís as a quantity or part of something.

Catalan often uses en with verbs when talking about:

• some of something
• an amount of something
• what remains of something

So:

• del pastís introduces the topic
• en resumes it inside the clause

This is very common in Catalan. The sentence is literally structured a bit like:

• Of the cake, there won’t remain much of it

That sounds odd in English, but it is natural in Catalan.

Quedarà is the future of quedar, and here it means will remain or will be left.

So:

• no en quedarà gaire = there won’t be much left

This future is used because the speaker is talking about what will be left later, after people have had some.

Here gaire means much.

In standard Catalan, gaire is very commonly used in:

• negative sentences
• questions
• some conditional contexts

So:

• no en quedarà gaire = there won’t be much left

This is very natural Catalan.

By contrast, in a plain affirmative statement, Catalan often prefers molt instead of gaire.

They express different ideas:

• prou = enough
• gaire = much / very much

So:

• Hi ha prou xocolata...? asks whether the amount is sufficient
• No en quedarà gaire says the remaining amount will be small

In other words:

• prou is about adequacy
• gaire is about quantity

That is why both appear in the same sentence without meaning the same thing.

Yes. It is a topicalized word order.

The speaker puts del pastís first to mark the topic, then continues with the clause:

• del pastís = as for the cake
• no en quedarà gaire = there won’t be much left of it

A more direct version could be something like:

• No en quedarà gaire, del pastís

but the original order is very natural if the speaker wants to contrast chocolate and cake:

• enough chocolate, yes
• cake, not much left

So the fronted del pastís helps create that contrast.
