Želim prenos broja.

Because broja is the genitive singular form of broj.

In Serbian, when one noun is closely connected to another noun, the second noun is often put in the genitive case. Here:

• prenos = transfer
• broja = of the number

So prenos broja literally means transfer of the number.

This is very natural in Serbian. English often uses of or a noun used like an adjective, but Serbian usually marks that relationship with case endings.

Prenos is in the accusative singular, because it is the direct object of želim.

• želim = I want
• I want what?
• prenos broja

For masculine inanimate nouns like prenos, the accusative looks the same as the nominative, so the form does not change.

Here is the structure:

• Želim = I want
• prenos = transfer
• broja = of the number

So grammatically, the sentence is:

• Želim
  • direct object
• The direct object is the noun phrase prenos broja

A very literal breakdown would be:

• I want
• a/the transfer
• of the number

Serbian does not have articles like English a and the.

So a noun like prenos can mean:

• a transfer
• the transfer
• just transfer in a general sense

The exact meaning depends on the situation. In a real conversation, especially at a mobile provider, Želim prenos broja is understood naturally without any article.

Yes, it is natural, especially in formal or service-related contexts, such as speaking to a mobile phone provider.

It sounds a bit like a service request, which fits the situation well. Serbian often uses noun phrases like this in practical, official, or business contexts.

A more verbal version is also common:

• Želim da prenesem broj. = I want to transfer the number.

Both are correct, but Želim prenos broja sounds slightly more like a formal request for the service itself.

Yes, absolutely.

That version uses a verb instead of the noun prenos:

• Želim da prenesem broj.
• literally: I want to transfer the number.

Compare the two:

• Želim prenos broja. = I want number transfer / I want the transfer of the number.
• Želim da prenesem broj. = I want to transfer the number.

The second version may feel more straightforward to an English speaker because it matches the English structure more closely. The first version is a bit more compact and service-oriented.

A rough pronunciation guide is:

• Želim ≈ ZHEH-leem
• prenos ≈ PREH-nos
• broja ≈ BROH-ya

A few important sounds:

• Ž sounds like the s in measure
• j sounds like English y
• r in Serbian is usually rolled or tapped
• lj in Želim is a single soft sound, similar to the lli in some pronunciations of million, though not exactly the same

So the whole sentence is approximately:

ZHEH-leem PREH-nos BROH-ya

The order Želim prenos broja is the most neutral and natural here.

Serbian word order is more flexible than English because cases show grammatical relationships, but word order still affects style and emphasis.

The normal pattern here is:

• verb first: Želim
• object after it: prenos broja

You could move things around in some contexts, but it would usually sound marked, poetic, or focused in a special way. For a normal request, Želim prenos broja is the best choice.

Želim is generally more polite and appropriate in this kind of situation.

• Želim = I want / I would like
• Hoću = I want / I will

In many contexts, hoću sounds more direct, stronger, or less polite. At a shop, office, or customer-service desk, želim is usually better.

So if you are making a request, Želim prenos broja sounds more courteous than Hoću prenos broja.

By itself, broj just means number, but in the right context it is very commonly understood as phone number.

Because prenos broja is a standard expression in telecom contexts, people will normally understand it as phone number transfer or number portability.

If you want to be extra explicit, you could say:

• Želim prenos telefonskog broja.

But in many real-life situations, simply prenos broja is enough.
