Nemam sitniš za autobus, pa ću platiti karticom.

Nemam means I do not have.

It comes from the verb imati = to have:

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

By contrast, nisam comes from biti = to be, and means I am not.

So:

• Nemam sitniš = I don’t have change
• Nisam umoran = I am not tired

English uses do not have, but Croatian simply negates the verb itself.

Sitniš means small change, loose change, or coins/small money.

In this sentence, Nemam sitniš za autobus means you do not have the small cash needed for the bus.

A few useful related words:

• novac = money
• sitniš = loose change / small change
• kusur = change you get back after paying

So:

• Nemam novac = I don’t have money
• Nemam sitniš = I don’t have small change
• Nemam kusur would usually sound odd unless you mean returned change in a specific context

Yes, literally it means for the bus, but in context it really means for the bus fare or to pay for the bus ride.

Croatian often uses za + accusative to express purpose or what something is intended for.

So:

• novac za kartu = money for a ticket
• sitniš za autobus = change for the bus

This is a natural, everyday way to say it. The speaker does not mean they want to buy a whole bus; the meaning is understood from context.

Also, Croatian has no articles, so autobus can mean the bus or a bus, depending on context.

Here pa means something like:

• so
• and so
• therefore
• in that case

In this sentence:

• Nemam sitniš za autobus, pa ću platiti karticom.
• I don’t have change for the bus, so I’ll pay by card.

It connects the first idea to the consequence in a very natural spoken way.

It is extremely common in Croatian conversation.

Compare:

• Nemam vremena, pa idem kasnije. = I don’t have time, so I’m going later.
• Pada kiša, pa ostajemo doma. = It’s raining, so we’re staying home.

Yes. Ću platiti is the future tense.

Croatian often forms the future with:

• a short form of htjeti = to want
• plus the infinitive

For I will, the clitic is ću.

So:

• platiti = to pay
• ću platiti = I will pay

Full pattern:

• ja ću platiti = I will pay

In your sentence, the subject ja is omitted because Croatian usually leaves out subject pronouns when the verb already shows the person clearly.

This is about aspect, which is very important in Croatian.

• platiti = perfective → to pay, as a completed action
• plaćati = imperfective → to be paying / to pay repeatedly or habitually

In this sentence, the speaker means one complete future action:

• I’ll pay by card.

That is why platiti is the natural choice.

Compare:

• Platit ću karticom. = I’ll pay by card.
• Plaćam karticom. = I pay by card / I am paying by card.
• Obično plaćam karticom. = I usually pay by card.

So platiti fits because the action is a single completed payment.

Because after verbs like platiti Croatian often uses the instrumental case to show the means or instrument used.

• kartica = card
• karticom = with/by card

So:

• platiti karticom = to pay by card

This is similar to English by card, but Croatian does it with a case ending rather than a preposition.

Other examples:

• pisati olovkom = to write with a pencil
• ići vlakom = to go by train
• otvoriti ključem = to open with a key

So the ending -om here marks the instrumental singular.

Because Croatian often drops subject pronouns when they are already clear from the verb form.

In this sentence:

• nemam already means I don’t have
• ću platiti already means I will pay

So ja is not necessary.

You could say:

• Ja nemam sitniš za autobus, pa ću platiti karticom.

But adding ja usually gives extra emphasis, something like:

• I don’t have change...

Croatian does this all the time, unlike English.

Because ću is a clitic, a short unstressed word that usually goes in second position in its clause.

In pa ću platiti karticom, the word pa comes first, and the clitic ću comes right after it.

That word order is very natural in Croatian:

• pa ću platiti = so I will pay

Clitics such as ću, sam, si, je, se often follow this second-position rule.

For example:

• Danas ću doći. = I will come today.
• Ako bude vremena, doći ću. = If there is time, I will come.

So pa ću is exactly what you would expect.

Yes. Both are correct, but the word order changes slightly depending on style and sentence structure.

You can say:

• Platit ću karticom.
• Ću platiti karticom is generally not used at the start by itself.
• In this sentence, after pa, the normal form is pa ću platiti karticom.

Croatian future tense allows two common patterns:

• ću + infinitive
• infinitive stem + ću in some positions

With platiti, that gives:

• ja ću platiti
• platit ću

Both mean I will pay, but in your sentence pa ću platiti karticom is the most natural phrasing.

It sounds natural and everyday.

Everything in it is common spoken Croatian:

• Nemam... = very everyday
• sitniš = common conversational word
• pa = very natural connector in speech
• platiti karticom = standard modern expression

So this is the kind of sentence you could really hear or use in daily life, especially in situations involving transport, shops, or tickets.
