Vostè vol que li ompli el got d'aigua?

Vostè is the formal singular word for you in Catalan. It is used in polite situations, for example with customers, strangers, older people, or in professional/service settings.

So this sentence sounds polite, like something a waiter, server, or shop assistant might say.

With vostè, Catalan uses third-person singular grammar, not second-person singular grammar.

Because vostè takes third-person singular verb forms.

So:

• tu vols = informal you want
• vostè vol = formal singular you want
• vostès volen = formal plural you want

Even though vostè means you, grammatically it behaves like he/she.

Here que introduces a subordinate clause: that I fill the glass for you.

Catalan often uses this pattern:

voler que + subjunctive

when one person wants someone else to do something.

So:

• Vostè vol omplir el got d'aigua? = Do you want to fill the glass of water?
• Vostè vol que li ompli el got d'aigua? = Do you want me to fill the glass for you?

The first means you would do the filling.
The second means I would do the filling.

Because after vol que, Catalan normally uses the subjunctive.

So ompli is the present subjunctive form of omplir.

Compare:

• omplo = I fill / I am filling (indicative)
• omple = he/she fills, or fill! to one person (indicative / imperative)
• ompli = that I fill / that he or she fill (subjunctive)

In this sentence, the meaning is:

Vostè vol que (jo) li ompli...
= Do you want me to fill...?

The person doing the filling is the speaker: I.

Catalan often leaves out subject pronouns when they are clear from the verb or context. So jo is understood, not stated.

You could say:

Vostè vol que jo li ompli el got d'aigua?

but that is usually unnecessary unless you want to emphasize I.

Li is an indirect object pronoun. Here it means to you, in the formal singular sense.

So the structure is roughly:

• li = to you
• ompli = I fill
• el got d'aigua = the glass of water

A very literal breakdown would be something like:

Do you want that I fill the glass of water for you?

In natural English, that becomes Do you want me to fill your glass with water? or similar.

Because the sentence uses vostè, Catalan also uses the corresponding polite pronoun li.

Yes. Li can mean:

• to him
• to her
• to you (formal singular)

In this sentence, because the person addressed is vostè, li is understood as to you.

This is normal in Catalan: formal you uses the same grammatical forms as third person.

Catalan often uses the definite article where English would use a possessive like your.

Since li already shows who is affected, el got naturally means your glass in context.

So Catalan prefers something like:

li ompli el got

rather than always saying:

li ompli el seu got

Using el seu got is possible, but often less natural unless you need to stress ownership or avoid confusion.

D'aigua comes from de + aigua.

Catalan drops the final e of de before a vowel, so:

• de aigua → d'aigua

Literally, got d'aigua means glass of water.

In context, after omplir, English often says fill the glass with water, while Catalan can still use got d'aigua naturally.

Yes, this is normal.

Catalan yes/no questions often use the same word order as statements. The fact that it is a question is shown by:

• intonation in speech
• the question mark in writing

So Vostè vol que li ompli el got d'aigua? is a perfectly normal way to ask this.

Yes. Catalan often drops subject pronouns when the meaning is clear.

So you could simply say:

Vol que li ompli el got d'aigua?

That sounds very natural. Including vostè makes the sentence a little more explicit, and can sound slightly more formal or emphatic.

The informal singular version would normally be:

Vols que t'ompli el got d'aigua?

Changes:

• vostè → implied tu
• vol → vols
• li → t' / et

So the main difference is that formal address uses third-person forms, while informal tu uses normal second-person forms.
