Potrošač će osporiti zaduženje.

• Potrošač = consumer
• će = the future-tense auxiliary, roughly will
• osporiti = to dispute, to challenge, to contest
• zaduženje = charge, debt, liability, depending on context

So the sentence literally looks like:

Consumer will dispute charge/debt.

Će is part of the Serbian future tense.

The basic pattern is:

subject + forms of hteti + infinitive

Here:

• potrošač = subject
• će = will for he/she/it
• osporiti = infinitive verb

So:

• ja ću osporiti = I will dispute
• ti ćeš osporiti = you will dispute
• on/ona će osporiti = he/she will dispute

In your sentence, potrošač is third person singular, so će is the correct form.

In Serbian, the future can often appear in two slightly different ways:

1. će + infinitive
2. clitic future attached to the verb form in some contexts

With a normal full subject before the verb, Potrošač će osporiti is the standard and very natural form.

So this is completely normal:

• Potrošač će osporiti zaduženje.

You may also see future constructions written differently in other sentence types, but for learners, this pattern is the safest one to recognize first.

This is an aspect question.

• osporiti = perfective
• osporavati = imperfective

In this sentence, osporiti is used because the action is seen as a single complete act in the future: the consumer will file or make the dispute.

Very roughly:

• osporiti = to dispute successfully / as one complete action
• osporavati = to be disputing / to dispute repeatedly or over time

After future auxiliary forms, Serbian very often uses the perfective verb when talking about a completed future event.

Zaduženje is the direct object of the verb osporiti, so it is in the accusative case.

However, zaduženje is a neuter singular noun, and for many neuter singular nouns:

• nominative = accusative

So:

• nominative: zaduženje
• accusative: zaduženje

That is why the form does not change.

It depends on context.

Zaduženje can mean things like:

• debt
• charge
• liability
• amount owed
• sometimes even an assigned responsibility in other contexts

In a consumer or banking context, it often means:

• a charge on an account
• a debit
• an amount the customer is being held responsible for

So if this sentence comes from banking, billing, or card disputes, The consumer will dispute the charge is often the most natural translation.

Yes, potrošač is grammatically masculine singular.

In Serbian, masculine forms are often used in a generic sense, especially in formal, legal, or administrative language. So potrošač can mean:

• a male consumer specifically, or
• a consumer in general

If someone wanted to specify a female consumer, they might use potrošačica, but in official language potrošač is often used generically.

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

The neutral order here is:

Potrošač će osporiti zaduženje.

But depending on emphasis, you could also see:

• Zaduženje će potrošač osporiti.
• Potrošač zaduženje će osporiti.

Those alternatives are more marked and depend on style or emphasis. For most learners, the original sentence is the best basic pattern to follow.

A rough English-friendly guide:

• Potrošač ≈ po-TRO-shach
• će ≈ something like cheh, but with a softer ć sound
• osporiti ≈ o-spo-REE-tee
• zaduženje ≈ za-DOO-zhe-nye

A few important sounds:

• š = sh as in shoe
• ž = zh as in measure
• č = ch as in church
• ć = a softer sound than č, often approximated by English ty/ch but softer
• nj = like ny in canyon

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

So potrošač can mean:

• a consumer
• the consumer

And zaduženje can mean:

• a charge
• the charge

The exact meaning depends on context. That is why one Serbian sentence can correspond to more than one natural English version.

Yes, it sounds fairly formal or administrative, especially because of the words potrošač, osporiti, and zaduženje.

It would fit well in contexts like:

• consumer protection
• banking
• billing disputes
• legal or official notices

In everyday conversation, a speaker might choose simpler wording depending on the exact situation, but this sentence is perfectly normal in formal Serbian.
