Dim je jak.

Dim means smoke.

It is a masculine noun in Serbian.

Je means is.

It is the 3rd person singular form of the verb biti (to be), so:

• Dim je jak. = The smoke is strong.

In Serbian, this short form je is very common in everyday sentences.

Serbian does not have articles like a or the.

So dim can mean:

• smoke
• the smoke
• sometimes even a smoke, depending on context

You understand which one is meant from the situation, not from an article.

Because jak has to agree with dim.

In Serbian, adjectives change form to match the noun’s:

• gender
• number
• case

Here, dim is:

• masculine
• singular
• nominative

So the adjective is also masculine singular nominative: jak

Compare:

• jak dim = strong smoke (masculine)
• jaka kafa = strong coffee (feminine)
• jako svetlo = strong/bright light (neuter)

Yes, jak literally means strong, but in English you may translate it differently depending on context.

With smoke, jak usually means something like:

• strong
• intense
• heavy
• pungent

So Dim je jak could mean the smoke is strong in smell or effect, not that it is physically muscular, of course.

This sentence is using predicate adjective structure:

• Dim = subject
• je = is
• jak = adjective describing the subject

So this is like English:

• The smoke is strong.

If the adjective comes directly before the noun, that usually makes a noun phrase:

• jak dim = strong smoke

So:

• Dim je jak. = The smoke is strong.
• Jak dim = strong smoke

Yes, Serbian word order is more flexible than English, but not every version sounds equally neutral.

The most neutral form here is:

• Dim je jak.

You may also hear:

• Jak je dim.

This can sound more marked, like emphasizing jak.

However, the short form je normally takes the second position in the sentence or clause, so that affects word order.

A simple English-friendly guide:

• Dim ≈ deem
• je ≈ yeh
• jak ≈ yahk

So the whole sentence sounds roughly like:

• deem yeh yahk

A few notes:

• j in Serbian is pronounced like English y in yes
• a is usually like a in father
• Serbian pronunciation is generally quite phonetic

Yes. Dim je jak is present tense:

• is

If you wanted the past or future, Serbian would change the form:

• Dim je bio jak. = The smoke was strong.
• Dim će biti jak. = The smoke will be strong.

You make it negative by changing je to nije:

• Dim nije jak. = The smoke is not strong.

This is a very common pattern:

• je = is
• nije = is not

Yes, dim is a masculine noun.

That is why it takes masculine adjective forms like:

• jak
• gust
• beo

For example:

• Dim je gust. = The smoke is thick.
• Dim je beo. = The smoke is white.

Not exactly.

Jak usually means strong/intense, not specifically thick.

If you want to say The smoke is thick, Serbian would more naturally use:

• Dim je gust.

So:

• Dim je jak. = The smoke is strong / intense
• Dim je gust. = The smoke is thick

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

The basic dictionary form of the noun is also nominative:

• dim

Since the sentence means Smoke is strong / The smoke is strong, dim is the thing being described, so nominative is the expected case.
