Serviser će završiti dijagnostiku.

Će + infinitive is a standard way to form the future tense in Serbian.

So in Serviser će završiti dijagnostiku,

• će = future auxiliary
• završiti = to finish / complete

Together, će završiti means will finish.

This is very similar to English will finish.

This is about aspect, which is very important in Serbian.

• završiti is perfective: it means to finish, to complete
• završavati is imperfective: it focuses more on the process, repetition, or ongoing action

In this sentence, the idea is that the technician will complete the diagnostic procedure, so završiti is the natural choice.

A learner-friendly way to think about it:

• završiti = finish it
• završavati = be finishing / finish regularly / work on finishing

Because dijagnostiku is in the accusative case, which is used here for the direct object of the verb.

The noun is:

• dijagnostika = nominative singular

But after a transitive verb like završiti (to finish), the thing being finished goes into the accusative:

• završiti dijagnostiku

This is a very common pattern with feminine nouns ending in -a:

• nominative: dijagnostika
• accusative: dijagnostiku

Other examples:

• knjiga → knjigu
• kontrola → kontrolu

Serviser is in the nominative case, because it is the subject of the sentence.

It answers the question who will finish the diagnostics?
Answer: serviser.

Since it is a masculine noun and the subject, the nominative form is used.

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

So serviser can mean:

• a technician
• the technician

And dijagnostiku can mean:

• a diagnostic procedure
• the diagnostics / the diagnostic check

Which one is intended depends on context, not on a separate article word.

This is one of the big differences from English.

Yes. Serbian word order is more flexible than English word order because case endings help show grammatical roles.

The neutral order here is:

• Serviser će završiti dijagnostiku.

But you could also hear:

• Dijagnostiku će završiti serviser.
• Serviser dijagnostiku će završiti. (less neutral, more marked)

These versions still mean roughly the same thing, but the focus changes.

For example:

• Dijagnostiku će završiti serviser can emphasize who will finish it.

So the original sentence is the most straightforward, neutral version.

Because će is a clitic, and clitics in Serbian usually appear near the second position in the sentence.

In a simple sentence like this:

• Serviser = first element
• će = clitic, placed right after it

So:

• Serviser će završiti dijagnostiku.

This second-position behavior is very common with short auxiliary and pronoun forms in Serbian.

Yes, that is also possible in many varieties of Serbian.

There are two common future constructions:

1. će + infinitive

   • Serviser će završiti dijagnostiku.

2. će da + present-tense form

   • Serviser će da završi dijagnostiku.

Both can mean the same thing: The technician will finish the diagnostics.

The version with the infinitive is often taught first and is very standard.
The će da + present structure is also very common in everyday speech.

Yes, often it can be omitted if the context already makes it clear who is being talked about.

For example:

• Završiće dijagnostiku.
• Će završiti dijagnostiku. (much less natural by itself in standard usage; Serbian normally attaches the future ending in forms like *završiće when the subject is omitted)*

More naturally:

• Završiće dijagnostiku. = He/she will finish the diagnostics.

However, keeping Serviser in the sentence makes the subject explicit and removes ambiguity.

In context, yes, it can refer to a diagnostic check, diagnostic procedure, or diagnostics in a service/repair sense.

Words like dijagnostika in Serbian often cover meanings that in English might be expressed in several ways depending on the situation:

• diagnostics
• diagnostic testing
• diagnostic procedure
• inspection / troubleshooting, depending on context

So even if the English translation shown to the learner uses one specific phrase, the Serbian word may be a bit broader in real usage.

Će is pronounced roughly like chyeh, but that English approximation is not perfect.

The important sound is ć, which is a soft sound, different from č.

A rough guide:

• ć = softer, more palatal
• č = harder, like English ch in church

So će is not quite the same as che.

This distinction can be hard for English speakers at first, but it becomes easier with listening practice.

The dictionary forms are:

• serviser = technician / repairman / service technician
• hteti → će = to want; its forms are also used to build the future tense
• završiti = to finish, complete
• dijagnostika = diagnostics / diagnostic procedure

A useful thing to notice is that će comes from the verb hteti, but in this sentence it is functioning as a future auxiliary, not with the full meaning to want.

A very literal breakdown is:

• Serviser = technician (subject, nominative)
• će = will (future auxiliary)
• završiti = finish / complete (perfective infinitive)
• dijagnostiku = diagnostics / diagnostic procedure (direct object, accusative)

So grammatically it is:

subject + future auxiliary + infinitive + direct object

That is why it maps neatly to English The technician will finish the diagnostics.
