Nemam ulaznicu za poslednju predstavu, ali imam dve ulaznice za sledeću.

In Serbian, the negative form of imati (to have) is usually built as a single word:

• imam = I have
• nemam = I do not have

So Nemam ulaznicu means I don’t have a ticket.

This is very common with a few verbs, where the negative form is written together:

• znam → ne znam
• imam → nemam
• hoću → neću

So here, nemam is simply the normal negative form.

Serbian often leaves out subject pronouns when they are already clear from the verb ending.

• Nemam already means I don’t have
• Imam already means I have

So Ja nemam... is possible, but it sounds more emphatic, like I don’t have... as opposed to someone else.

The version in the sentence is the most natural neutral wording.

Ulaznica means ticket, especially an admission ticket or entry ticket.

It comes from the idea of entry/admission:

• ulaz = entrance, entry
• ulaznica = ticket for entry

So in this sentence:

• ulaznicu = a ticket
• dve ulaznice = two tickets

Because ulaznicu is in the accusative singular, not the dictionary form.

The dictionary form is:

• ulaznica = ticket

But after imam / nemam when the noun is the direct object, you use the accusative:

• Imam ulaznicu = I have a ticket
• Nemam ulaznicu = I don’t have a ticket

Since ulaznica is a feminine noun, its accusative singular ends in -u:

• nominative: ulaznica
• accusative: ulaznicu

Because two changes according to gender in Serbian.

• dva is used with masculine and neuter nouns
• dve is used with feminine nouns

Since ulaznica is feminine, you say:

• dve ulaznice = two tickets

Compare:

• dva filma = two films
• dva pisma = two letters
• dve knjige = two books

After the numbers 2, 3, and 4, Serbian nouns usually appear in a special form that looks like the genitive singular for many feminine nouns.

So:

• jedna ulaznica = one ticket
• dve ulaznice = two tickets
• tri ulaznice = three tickets
• četiri ulaznice = four tickets

That is why you get ulaznice, not ulaznicu.

Predstava usually means show, performance, or play, depending on context.

It can refer to:

• a theater performance
• a staged show
• sometimes a general performance/event

In this sentence, poslednja predstava and sledeća most naturally mean the last performance/show and the next one.

Because it follows the preposition za in the meaning for.

Here:

• ulaznicu za predstavu = a ticket for a performance/show

With this meaning, za takes the accusative, so:

• predstava → predstavu

That is why the sentence says:

• za poslednju predstavu
• za sledeću

Here za means for.

So:

• ulaznica za predstavu = a ticket for a performance
• ulaznice za sledeću = tickets for the next one

This is a very common use of za:

• karta za autobus = ticket for the bus
• poklon za tebe = a gift for you
• mesto za sedenje = a place for sitting / a seat

It can depend on context.

Poslednji / poslednja / poslednje can mean:

• last in a sequence, as in final
• most recent / previous, depending on situation

So poslednju predstavu could mean:

• the last/final performance
• or the previous/most recent performance

If the learner already knows the intended meaning from context, that resolves the ambiguity. On its own, Serbian can allow both readings.

These are adjective forms that agree with predstavu, which is:

• feminine
• singular
• accusative

So the adjective must match that noun.

Dictionary forms:

• poslednja = last
• sledeća = next

Accusative singular feminine:

• poslednju
• sledeću

So:

• za poslednju predstavu = for the last performance
• za sledeću (predstavu) = for the next one

Because Serbian often leaves out a noun when it is obvious from context.

In full, the sentence could say:

• imam dve ulaznice za sledeću predstavu

But since predstavu was already mentioned, Serbian naturally omits it:

• imam dve ulaznice za sledeću

This is like English for the next one, where one stands in for the repeated noun. In Serbian, the adjective itself can carry that meaning when the noun is understood.

Yes, absolutely.

Both are correct:

• imam dve ulaznice za sledeću
• imam dve ulaznice za sledeću predstavu

The version without predstavu is more natural when you want to avoid repeating the same noun.

This is normal Serbian word order.

• ali = but
• nemam = I don’t have
• imam = I have

So the structure is:

• I don’t have X, but I have Y

Serbian word order is fairly flexible, but this version is the most straightforward and natural. You could move words around for emphasis, but the given sentence is the neutral way to say it.

No, that is perfectly natural.

The sentence contrasts:

• I don’t have one ticket for the last performance
• but I do have two tickets for the next one

So the first clause is singular because it refers to a ticket, while the second is plural because it refers to two tickets.

Usually yes. Sledeći means next or following.

Examples:

• sledeći dan = the next day
• sledeća stanica = the next stop
• sledeća predstava = the next performance

In this sentence, za sledeću means for the next one.

Yes. It sounds natural and idiomatic.

A Serbian speaker would easily understand it as something like:

• I don’t have a ticket for the last performance, but I have two tickets for the next one.

It uses very normal vocabulary and grammar:

• nemam / imam
• ulaznica
• za
• poslednji / sledeći
• omission of a repeated noun in the second clause

So it is a good example of everyday Serbian structure.
