Al despatx de l'empresa es decideix tot quan una clienta espera resposta.

Al is a contraction of a + el.

• a can mean to, at, or sometimes in, depending on context
• el means the

So al despatx literally looks like to the office, but in Catalan this often works like at/in the office when talking about location.

So:

• al despatx = in/at the office

Despatx usually means office or study.

In this sentence, el despatx de l'empresa means the company office or the office of the company.

A learner should note that despatx is not the main general word for a whole workplace building. It often refers to:

• an office room
• a professional office
• a private office/study

Because empresa is a feminine singular noun, so it normally takes the article la:

• la empresa

But before a vowel sound, la becomes l':

• l'empresa

So:

• de l'empresa = of the company

This is the normal way to say possession or association in Catalan.

Here es makes the verb impersonal or passive-like.

Es decideix tot means something like:

• everything gets decided
• everything is decided
• people decide everything

Catalan often uses es + verb where English might use:

• a passive: is decided
• an indefinite subject: they decide

So es decideix does not mean it decides itself here. It is a common Catalan structure.

Because in this sentence, tot is being treated as a singular idea: everything.

So the verb agrees in the singular:

• tot es decideix
• es decideix tot

Compare:

• Tot es decideix aquí. = Everything is decided here.
• Totes les coses es decideixen aquí. = All the things are decided here.

Since tot is singular, decideix is singular too.

Catalan word order is flexible, and this structure is very natural:

• es decideix tot

It puts the action first and then the thing affected. You could also see:

• tot es decideix

Both are possible, but es decideix tot sounds very natural in context.

Catalan often places nouns, pronouns, or indefinite words after the verb in impersonal/passive-like structures.

Because clienta is the feminine form of client.

• un client = a male client / a client
• una clienta = a female client

The sentence specifically refers to a female client, so una clienta is used.

This is common in Catalan: many nouns referring to people change form for gender.

Catalan often omits the article where English would use an answer or a response.

So:

• espera resposta literally = waits for response
• natural English = is waiting for a response

This article omission is common with abstract nouns or in set expressions.

You may also hear:

• espera una resposta

That is also possible, but espera resposta sounds more general or idiomatic.

Quan means when and introduces a time clause.

So:

• quan una clienta espera resposta = when a female client is waiting for a response

It tells us under what circumstances or at what time everything gets decided.

Yes. In Catalan, the simple present often covers both:

• waits
• is waiting

So una clienta espera resposta can naturally mean:

• a client waits for a response
• a client is waiting for a response

In many everyday sentences, Catalan uses the simple present where English prefers the present continuous.

Yes. The sentence is quite natural:

• Al despatx de l'empresa = location first
• es decideix tot = impersonal/passive-like statement
• quan una clienta espera resposta = time/situation clause

Catalan often starts with a location or setting, especially when establishing context. English can do this too, but Catalan uses it very comfortably.

Yes. Depending on context, it could be rendered as:

• everything is decided
• everything gets decided
• they decide everything

All of these reflect the Catalan es structure. The exact English version depends on style and context, not on a big difference in Catalan meaning.
