Roming je skup.

A simple approximation is:

ROH-ming yeh skoop

More precisely:

• Roming → ROH-ming
• je → yeh
• skup → skoop

A few pronunciation notes:

• Serbian j is pronounced like English y in yes
• u is pronounced like oo in food
• r is usually trilled or tapped, not like a typical English r

Yes. Roming is the Serbian form of English roaming, especially in the mobile-phone/telecom sense.

Serbian often adapts international words to its own spelling and pronunciation, so roaming becomes roming.

In everyday usage, you may also see the English spelling roaming, especially in ads, websites, or technical contexts, but roming is a normal Serbianized form.

Je means is.

It is the 3rd person singular present-tense form of the verb biti (to be).

So:

• Roming = roaming
• je = is
• skup = expensive

This is a very common Serbian sentence pattern:

noun + je + adjective

For example:

• Telefon je nov. = The phone is new.
• Hotel je skup. = The hotel is expensive.

Because skup agrees in gender and number with the noun it refers to.

Roming is treated as a masculine singular noun, so the adjective also takes the masculine singular form:

• masculine: skup
• feminine: skupa
• neuter: skupo
• plural masculine: skupi
• plural feminine/neuter: skupe

So:

• Roming je skup. = Roaming is expensive.
• Usluga je skupa. = The service is expensive.
• More je skupo. = The sea/coast vacation is expensive.
  (depending on context and the noun)

A lot of Serbian nouns ending in a consonant are masculine, and roming ends in -g, so it is treated as masculine.

This is not a perfect rule for every noun, but it is a very strong and useful pattern:

• nouns ending in a consonant are often masculine
• many nouns ending in -a are feminine
• many nouns ending in -o or -e are neuter

So an English speaker can often correctly guess that roming is masculine.

Because Serbian has no articles like English a/an/the.

So Roming je skup can mean:

• Roaming is expensive
• The roaming is expensive
  depending on context, though the first is the more natural translation here.

English speakers often look for the, but Serbian usually expresses definiteness through context rather than articles.

Yes, Serbian word order is more flexible than English, but the most neutral version here is:

Roming je skup.

You could also say:

Skup je roming.

That version is possible, but it sounds more marked or emphatic, as if you are stressing expensive.

For learners, the safest default is: subject + je + adjective

Normally, no. In standard Serbian, you usually keep je in this kind of sentence.

So:

• correct: Roming je skup.
• not standard here: Roming skup.

Serbian sometimes omits forms of to be in certain styles, headlines, or very informal speech, but as a learner, you should include je.

In this sentence, yes: skup means expensive.

But the word can have other uses depending on context. Serbian words often have more than one meaning, and learners may also notice related forms.

For everyday learning, the important thing here is:

• skup = expensive

Examples:

• Auto je skup. = The car is expensive.
• Stan je skup. = The apartment is expensive.

You add nije (is not):

Roming nije skup. = Roaming is not expensive.

This is very useful:

• je = is
• nije = is not

So you can build many simple sentences this way:

• Telefon je skup. = The phone is expensive.
• Telefon nije skup. = The phone is not expensive.

A very common way is:

Da li je roming skup? = Is roaming expensive?

Another common spoken pattern is:

Je li roming skup?

Both are used, but Da li je... is especially clear and learner-friendly.

So you can think of the three basic versions like this:

• Roming je skup. = Roaming is expensive.
• Roming nije skup. = Roaming is not expensive.
• Da li je roming skup? = Is roaming expensive?

Yes. In Serbian, as in English, the first word of a sentence is capitalized.

So here it is Roming because it starts the sentence.

If it appeared in the middle of a sentence, it would normally be lowercase:

• Mislim da je roming skup. = I think roaming is expensive.

Yes, it is natural and easy to understand.

That said, in real life people may also say slightly longer versions such as:

• Roming je veoma skup. = Roaming is very expensive.
• Mobilni roming je skup. = Mobile roaming is expensive.
• Roming u inostranstvu je skup. = Roaming abroad is expensive.

But Roming je skup. is a perfectly normal short sentence for practice and everyday use.
