Rok pozajmice je važan.

Here rok means term, period, or deadline, depending on context.

So Rok pozajmice je važan most naturally means something like:

• The loan period is important
• The borrowing term is important
• in some contexts, The due date matters

In Serbian, rok is a very common word for a time limit or fixed period.

Because pozajmice is in the genitive singular.

The base noun is:

• pozajmica = loan

After a noun like rok (term/period/deadline), Serbian often uses another noun in the genitive to show of what:

• rok pozajmice = the term of the loan / the loan period

This is similar to English structures like:

• the end of the book
• the price of the car

So:

• pozajmica = nominative singular
• pozajmice = genitive singular

Rok is in the nominative singular because it is the subject of the sentence.

The structure is:

• Rok pozajmice = the subject
• je = is
• važan = important

So literally:

• The loan term
  • is
    • important

Because važan agrees with rok, which is a masculine singular noun.

In Serbian, adjectives must agree with the noun they describe in gender, number, and usually case.

Here:

• rok = masculine singular
• so the adjective must also be masculine singular: važan

Compare:

• rok je važan = the term is important
• pozajmica je važna = the loan is important
• pravilo je važno = the rule is important

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

So:

• je = is

In this sentence:

• Rok pozajmice je važan = The loan period is important

Serbian often uses forms of biti just like English uses am/is/are.

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

The neutral, standard version is:

• Rok pozajmice je važan.

But you may also see:

• Važan je rok pozajmice.

That version puts more focus on važan (important), almost like:

• What is important is the loan period.

Even though the word order can change, the original sentence is the most straightforward one for learners.

Serbian has no articles like a/an/the.

So rok pozajmice can mean:

• the loan period
• a loan period

The exact meaning depends on context.

In many simple example sentences, English will often translate it with the because that sounds more natural:

• Rok pozajmice je važan. = The loan period is important.

Not exactly, though they can overlap.

• pozajmica = a loan or something borrowed; often a general word
• zajam = loan, often more formal or financial
• kredit = credit or a bank loan

So rok pozajmice sounds natural for a borrowing period, especially in everyday or library-style contexts. In a banking context, other words might also be used depending on what kind of loan is meant.

A simple pronunciation guide is:

• Rok = roughly roke
• pozajmice = po-zai-mee-tseh
• je = yeh
• važan = VAH-zhan

A few helpful notes:

• j in Serbian sounds like English y
• ž sounds like the s in measure
• c usually sounds like ts

So je važan sounds roughly like yeh VAH-zhan.

Sometimes yes, but only if the context supports that meaning.

Because rok can refer to a time limit, deadline, or term, the best translation depends on what kind of pozajmica is being discussed.

Possible translations include:

• The loan period is important
• The term of the loan is important
• The due date is important if the focus is on the deadline

Without context, loan period/term is usually the safest general translation.

It follows a very common Serbian pattern:

• [noun phrase in nominative] + je + [adjective]

Here that gives:

• Rok pozajmice = noun phrase / subject
• je = is
• važan = adjective

So the pattern is:

• The X is Y

This is a very useful model for making your own sentences, for example:

• Plan je dobar. = The plan is good.
• Datum je važan. = The date is important.
• Rok isporuke je kratak. = The delivery deadline is short.
