Rashod je neočekivan.

Je is the 3rd person singular present tense of biti (to be), so it means is.

So the structure is:

• Rashod = subject
• je = is
• neočekivan = adjective/predicate adjective

Serbian normally uses je in this kind of sentence, unlike Russian, where the present-tense to be is often omitted. In standard Serbian, Rashod neočekivan would sound incomplete or nonstandard in ordinary usage.

Because it agrees with rashod.

In Serbian, adjectives must match the noun in:

• gender
• number
• case

Rashod is:

• masculine
• singular
• nominative

So the adjective also appears as neočekivan.

Compare:

• Rashod je neočekivan. → masculine singular
• Isplata je neočekivana. → feminine singular
• Kašnjenje je neočekivano. → neuter singular
• Troškovi su neočekivani. → masculine plural

It is in the nominative case because it is the subject of the sentence.

The adjective neočekivan is also in the nominative because it is linked to the subject through je.

So this is a basic subject + to be + adjective sentence.

Rashod is a somewhat formal or financial/accounting word. It usually means:

• expense
• expenditure
• outflow
• cost item in a financial sense

It is often used in business, accounting, administration, and economics.

Learners should know that in everyday speech, people may more often use words like:

• trošak = cost/expense
• troškovi = costs/expenses

So rashod is correct, but it sounds more technical or formal than some everyday alternatives.

It is an adjective, but it is clearly related to the verb očekivati (to expect).

Breakdown:

• očekivati = to expect
• očekivan = expected
• neočekivan = unexpected

The prefix ne- makes it negative, just like un- or not in English.

So neočekivan literally means something like not expected.

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

The neutral order here is:

• Rashod je neočekivan.

But you could also say:

• Neočekivan je rashod.

That version puts more focus or emphasis on neočekivan.

Very roughly:

• Rashod je neočekivan. = neutral statement
• Neočekivan je rashod. = It is the expense that is unexpected / stronger emphasis on unexpected

Both are grammatical, but the first one is the most straightforward for learners.

Because Serbian has no articles.

English says:

• The expense is unexpected
• An expense is unexpected

Serbian does not have separate words for a/an/the. Context tells you whether something is definite or indefinite.

So Rashod je neočekivan can correspond to English with or without an article, depending on context.

A learner will often want help with these sounds:

• š = sh as in shoe
• č = ch as in church
• j = y as in yes

A rough pronunciation guide:

• Rashod ≈ RA-shod
• je ≈ ye
• neočekivan ≈ ne-o-CHE-ki-van

A few notes:

• Serbian spelling is quite phonetic, so words are usually pronounced as written.
• je is short and unstressed in normal speech.
• neočekivan has four clear parts: ne-o-če-ki-van.

Sometimes yes, but unexpected is the more direct and accurate meaning.

• neočekivan = unexpected
• iznenađujuć / iznenađujuće = surprising

In many contexts, something unexpected is also surprising, but they are not exactly the same idea.

So for this sentence, unexpected is the safest choice.

It is natural, but it sounds somewhat formal, especially because of rashod.

This kind of sentence fits well in:

• business language
• accounting
• reports
• official explanations

In casual conversation, people might be more likely to say something using trošak or troškovi, depending on the context.

So the grammar is completely normal, but the vocabulary leans a bit toward formal/financial Serbian.

Yes. Serbian can be written in both Latin and Cyrillic script.

The Cyrillic version is:

Расход је неочекиван.

Letter by letter:

• Rashod → Расход
• je → је
• neočekivan → неочекиван

Both scripts are standard in Serbian.

In financial language, the usual opposite is prihod.

• rashod = expense / expenditure
• prihod = income / revenue

So a learner may notice this useful contrast:

• Prihod je visok. = The income/revenue is high.
• Rashod je neočekivan. = The expense is unexpected.

This pair is especially common in accounting and business Serbian.
