Odjavna špica traje kratko.

It refers to the end credits or closing credits of a film, show, or video.

• špica is commonly used for the credits sequence
• odjavna means something like closing, sign-off, or at the end

So odjavna špica is the part at the end, not the opening credits.

Because špica is a feminine singular noun, and the adjective has to agree with it.

So:

• odjavna = feminine singular
• špica = feminine singular

In Croatian, adjectives change their form to match the noun in gender, number, and case.

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

The sentence structure is basically:

• Odjavna špica = the subject
• traje = lasts
• kratko = briefly / for a short time

So odjavna špica is the thing doing the action of lasting.

Traje means lasts or continues for some time.

It is the:

• 3rd person singular
• present tense
• form of the verb trajati = to last

So:

• Film traje dva sata. = The film lasts two hours.
• Pauza traje kratko. = The break lasts a short time.

Because kratko is being used as an adverb, not as an adjective.

Here it modifies the verb traje:

• traje kratko = lasts briefly / does not last long

If you used kratka, that would be an adjective describing the noun:

• Odjavna špica je kratka. = The end credits are short.

So the difference is:

• traje kratko = lasts a short time
• je kratka = is short

Both can be natural, but they are built differently.

Yes. In this sentence, kratko functions adverbially.

A helpful way to think of it is:

• adjective: kratak / kratka / kratko = short
• adverbial use: kratko = shortly / for a short time

Croatian often uses the neuter form in this kind of adverb-like role.

Yes, definitely.

That version means almost the same thing, but the grammar is different:

• Odjavna špica traje kratko. = The end credits last a short time.
• Odjavna špica je kratka. = The end credits are short.

The first focuses on duration with the verb trajati. The second uses biti + adjective to describe the credits.

Because Croatian does not have articles like the or a/an.

So odjavna špica can mean:

• the end credits
• end credits
• sometimes even an end-credit sequence

The exact meaning depends on context.

No, Croatian word order is fairly flexible.

The neutral order here is:

• Odjavna špica traje kratko.

But other orders are possible, for example:

• Kratko traje odjavna špica.
• Odjavna špica kratko traje.

These alternatives may sound more marked or stylistic, depending on context. The original version is a very normal, straightforward order.

No, trajati is normally intransitive.

It does not take a direct object here. Instead, it describes how long something lasts.

Examples:

• Sastanak traje dugo. = The meeting lasts a long time.
• Predstava traje dva sata. = The performance lasts two hours.

So in your sentence, kratko is not an object. It tells us about the duration.

Yes. That is exactly the same pattern.

For example:

• Odjavna špica traje kratko. = The end credits do not last long.
• Odjavna špica traje dugo. = The end credits last a long time.

This is a very useful structure:

• X traje kratko
• X traje dugo
• X traje pet minuta

Not necessarily. Croatian can use a few expressions depending on context and style.

For example, learners may also encounter:

• završna špica = ending/final credits
• odjavna špica = closing credits

Both can be natural. The exact preference may vary by speaker or context.

Špica is pronounced approximately like shpee-tsa.

A few useful points:

• š sounds like sh in ship
• c sounds like ts in cats

And traje is approximately TRAH-yeh, with j pronounced like y in yes.

The pattern is:

[subject] + traje + [duration expression / adverb]

So here:

• Odjavna špica = subject
• traje = lasts
• kratko = briefly / for a short time

You can build many similar sentences:

• Reklama traje kratko. = The commercial is short / lasts a short time.
• Sastanak traje dugo. = The meeting lasts a long time.
• Film traje dva sata. = The film lasts two hours.
