Što se tiče rominga, želim internet dodatak.

Što se tiče is a very common expression meaning as for, regarding, or when it comes to.

So in this sentence, Što se tiče rominga introduces the topic:

• As for roaming...
• Regarding roaming...
• When it comes to roaming...

It is a fixed phrase, so learners should try to remember it as one unit.

Because što se tiče is followed by the genitive case.

So:

• base form: roming
• after što se tiče: rominga

This is one of the most useful things to remember about the phrase:

• što se tiče + genitive

More examples:

• Što se tiče cene... = As for the price...
• Što se tiče interneta... = As for the internet...
• Što se tiče putovanja... = As for the trip...

In this expression, standard usage is što se tiče, not šta se tiče.

Even though learners often know both što and šta as forms related to what, this phrase is fixed as:

• što se tiče

So it is best to learn it exactly that way. In everyday speech, you may hear variation in some regions, but for standard Serbian, što se tiče is the safe and correct choice.

Se is the reflexive particle. The verb here is ticati se, which means to concern, to relate to, or to touch upon.

So:

• ticati se nečega = to concern something / to relate to something

In practice, though, learners usually meet it most often in the fixed phrase:

• što se tiče + genitive

You do not need to translate it word-for-word every time. It is better to understand the whole phrase naturally as as for / regarding.

In this context, internet dodatak means an internet add-on, usually an extra mobile data package.

In telecom language, dodatak is something extra added to your plan. So internet dodatak is not just the internet in general, but an additional package for internet/data use.

Depending on the provider, similar expressions might be:

• internet dodatak
• dodatak za internet
• internet paket
• data dodatak

But in the sentence you gave, internet dodatak is understood as an extra data/internet package.

Because Serbian does not have articles like English a/an/the.

So:

• želim internet dodatak can mean I want an internet add-on or I want the internet add-on, depending on context.

Serbian usually leaves that information to context, word order, or other words if needed.

This is normal, and English speakers often need time to get used to it.

Želim is grammatically correct and clear: I want.

However, in real-life service situations, Serbian often sounds more natural or polite with softer phrasing, for example:

• Želeo/želela bih internet dodatak. = I would like an internet add-on.
• Hteo/hteIa bih internet dodatak. = I would like / I’d want an internet add-on.

So:

• Želim internet dodatak = direct, understandable
• Želeo bih... / Želela bih... = more polite/natural in many situations

Still, the original sentence is perfectly understandable.

The comma separates the introductory topic phrase from the main statement.

Structure:

• Što se tiče rominga, = As for roaming,
• želim internet dodatak. = I want an internet add-on.

This is similar to English punctuation in sentences like:

• As for roaming, I want a data add-on.

So the comma helps show that the first part sets the topic, and the second part gives the main message.

Yes, Serbian word order is fairly flexible, but the original order is natural and clear.

Your sentence:

• Što se tiče rominga, želim internet dodatak.

This works well because it first sets the topic (roaming) and then states what the speaker wants.

You could also say things in other ways depending on emphasis, but not every rearrangement sounds equally natural. For learners, the original sentence is a good model.

A simple pronunciation guide:

• Što ≈ shto
• se ≈ seh
• tiče ≈ TEE-cheh
• rominga ≈ ROH-min-ga
• želim ≈ ZHEH-leem
• internet ≈ een-tehr-NET
• dodatak ≈ doh-DAH-tak

A few useful sound notes:

• š sounds like sh in shoe
• č sounds like ch in church
• ž sounds like the s in measure

So a rough full version would be:

Shto se TEE-cheh ROH-min-ga, ZHEH-leem een-tehr-NET doh-DAH-tak.

Yes. It is a borrowed word from English roaming, adapted to Serbian spelling as roming.

This is very common in technology and telecom vocabulary. Serbian often adapts international words so they fit Serbian spelling and grammar.

That is why it can also take Serbian case endings:

• roming
• rominga
• romingu

So even though it originally comes from English, in Serbian it behaves like a regular noun.
