Pristupna lozinka nije u servisnom izveštaju.

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

So:

• Pristupna lozinka can mean the access password or an access password
• u servisnom izveštaju can mean in the service report or in a service report

Which one is meant depends on context. In your sentence, English would most naturally use the: The access password is not in the service report.

Literally, it means something like access password.

• pristup = access
• pristupna = access-related / for access
• lozinka = password

So pristupna lozinka is the normal way to say access password or simply password used for access/login.

Because pristupna has to agree with lozinka.

In Serbian, adjectives change form to match the noun in:

• gender
• number
• case

Here:

• lozinka is feminine singular
• so the adjective must also be feminine singular
• therefore: pristupna lozinka

Compare:

• pristupni kod = access code (kod is masculine)
• pristupno ime = access name / login name (ime is neuter)
• pristupna lozinka = access password (lozinka is feminine)

The base form is lozinka, and yes, it is the standard Serbian word for password.

It comes from lozinka, a noun meaning a secret word or password. In modern usage, it is the normal word for digital passwords too.

You may also sometimes hear šifra in some contexts, but lozinka is usually the most direct and standard translation of password.

Because the negative form of je is a single word: nije.

This comes from the verb biti = to be.

Present tense, 3rd person singular:

• je = is
• nije = is not

So:

• Lozinka je u izveštaju. = The password is in the report.
• Lozinka nije u izveštaju. = The password is not in the report.

This is just how Serbian forms the negative here: not as two separate words, but as one.

Because after u meaning in, Serbian usually uses the locative case when talking about location.

Here the phrase means in the service report, so we need the locative:

• dictionary form: servisni izveštaj
• locative singular: u servisnom izveštaju

Both words change:

• servisni → servisnom
• izveštaj → izveštaju

So the pattern is:

• u + locative = in / at / on (location)

Examples:

• u gradu = in the city
• u školi = at school / in the school
• u izveštaju = in the report

Izveštaju is the locative singular form of the noun izveštaj.

• dictionary form (nominative singular): izveštaj = report
• locative singular: izveštaju = in/on/about the report, depending on the preposition

In this sentence:

• u izveštaju = in the report

So if you look up the word in a dictionary, you would look for izveštaj, not izveštaju.

Because adjectives must match the noun they describe in case, number, and gender.

The noun is:

• izveštaj — masculine singular

After u in the meaning in, it goes into the locative singular:

• izveštaj → izveštaju

The adjective must match that:

• servisni → servisnom

So:

• servisni izveštaj = service report
• u servisnom izveštaju = in the service report

This kind of agreement is a very important part of Serbian grammar.

Yes. Serbian word order is more flexible than English word order.

The neutral order here is:

• Pristupna lozinka nije u servisnom izveštaju.

But you could also hear:

• U servisnom izveštaju nije pristupna lozinka.
• Nije u servisnom izveštaju pristupna lozinka.

These alternatives are possible, but they sound more marked and may shift emphasis.

The original sentence is the most natural if you are simply stating a fact:

• topic: Pristupna lozinka
• comment: nije u servisnom izveštaju

Usually yes, in context.

• servisni = service / maintenance-related
• izveštaj = report

So servisni izveštaj can mean:

• service report
• maintenance report
• technician’s report

The exact English wording depends on the situation. If this is about IT or equipment repair, service report is a very natural translation.

A simple pronunciation guide:

• Pristupna ≈ PREE-stoop-na
• lozinka ≈ lo-ZEEN-ka
• nije ≈ NEE-ye
• u ≈ oo
• servisnom ≈ SEHR-vees-nom
• izveštaju ≈ eez-VEHSH-ta-yoo

A few helpful notes:

• j in Serbian is pronounced like English y in yes
• ž sounds like the s in measure
• š sounds like sh

So izveštaju has a y sound in the last part: -taju.

That is a dialect/standard-variant difference.

You may see:

• izveštaj — Ekavian
• izvještaj — Ijekavian

Both are standard, depending on the regional variety of Serbian.

So these are both possible:

• u servisnom izveštaju
• u servisnom izvještaju

They mean the same thing. If your learning materials use one variety, it is best to stay consistent with that variety.

Yes, possibly.

The preposition u most directly means in, but English sometimes prefers on with documents, forms, lists, and reports.

So depending on context, both of these can work in English:

• The access password is not in the service report.
• The access password is not on the service report.

The Serbian sentence itself is still perfectly natural. The difference is mostly about what sounds most idiomatic in English for that kind of document.
