Internet veza je jaka.

Because veza is a feminine noun in Serbian, and adjectives must agree with the noun in gender, number, and case.

• veza = feminine singular
• so the adjective must also be feminine singular: jaka

Compare:

• jak signal = a strong signal (signal is masculine)
• jaka veza = a strong connection (veza is feminine)
• jako svetlo = a strong/bright light (svetlo is neuter)

So jaka is the correct form here.

Je is the 3rd person singular form of the verb biti (to be).

So in this sentence:

• Internet veza = internet connection
• je = is
• jaka = strong

Serbian uses je much like English uses is.

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

So where English says:

• The internet connection is strong

Serbian simply says:

• Internet veza je jaka.

Whether it means an internet connection, the internet connection, or internet connection(s) depends on context.

Yes, it is a very natural and common expression meaning internet connection.

In Serbian, it is normal to put two nouns together like this, where the first noun functions a bit like a descriptor:

• internet veza = internet connection
• telefon broj is less standard; usually broj telefona
• wifi mreža = Wi‑Fi network

You may also hear:

• veza sa internetom = connection to the internet
• internetska veza = internet connection

But internet veza is perfectly natural in everyday speech.

Here internet is being used as a modifying noun before veza, and in this kind of expression it often stays in its basic form.

So:

• internet veza = internet connection

This is similar to how Serbian sometimes uses borrowed or technical nouns in front of another noun without changing them.

However, in other sentence patterns, internet can change by case:

• na internetu = on the internet
• sa interneta = from the internet

So the word can decline, but in internet veza it stays in its base form.

Yes. Internetska veza je jaka is also correct.

There is a small style difference:

• internet veza sounds very common and everyday
• internetska veza sounds a bit more adjective-based, sometimes slightly more formal or standard-written

Both are understandable and correct.

Literally, jaka means strong, but in this context it can also suggest:

• strong
• good
• stable
• reliable

So even if the direct translation is strong, the intended meaning may be closer to:

• The internet connection is good
• The internet connection is strong/stable

This is common in Serbian: physical words like jak can be used more broadly.

Yes, Serbian word order is more flexible than English, though some orders sound more natural than others.

The most neutral order is:

• Internet veza je jaka.

You could also hear:

• Jaka je internet veza. — puts more focus on jaka
• Internet veza jaka je. — possible, but less natural in ordinary speech

So while Serbian allows flexibility, the original sentence is the most straightforward and standard.

A simple approximate pronunciation for an English speaker is:

• Internet → IN-tehr-net
• veza → VEH-zah
• je → yeh
• jaka → YAH-kah

A rough full pronunciation: IN-tehr-net VEH-zah yeh YAH-kah

A few useful notes:

• j in Serbian is pronounced like English y in yes
• z is like English z
• vowels are usually clear and short: a, e, i, o, u

The sentence is in the nominative because Internet veza is the subject, and jaka is the predicate adjective agreeing with it.

Breakdown:

• internet veza = nominative singular
• je = verb
• jaka = feminine singular nominative

That is why the adjective appears as jaka, not in some other case form.

Usually, in standard Serbian, no—you keep je in this kind of present-tense sentence.

So:

• Internet veza je jaka. = correct
• Internet veza jaka. = not standard as a full normal sentence

In headlines, notes, or very informal speech, people sometimes drop forms of to be, but for learners, it is best to use je here.

Not always. Veza is a broad word and can mean several things depending on context, such as:

• connection
• link
• relationship
• tie
• contact

Examples:

• telefonska veza = telephone connection
• veza između dve tačke = a connection between two points
• ljubavna veza = romantic relationship

So in internet veza, context makes it clear that veza means connection.

Sometimes, but the meaning changes a little.

• Internet veza = the internet connection itself
• Signal je jak. = the signal is strong

So signal refers more to reception or signal strength, while veza refers to the connection as a whole.

For example:

• Wi‑Fi signal je jak, ali internet veza je spora. = The Wi‑Fi signal is strong, but the internet connection is slow.

So they are related, but not identical.
