Kuda ideš poslije posla?

Kuda is used with movement. It means something like where to / which way.

So:

• gdje = where (location, being somewhere)
• kuda = where to / which way (movement)

That is why Kuda ideš? works for Where are you going?

A closely related word is kamo, which also asks about destination. In everyday speech, kuda ideš? and kamo ideš? can both be used, although kuda can sometimes suggest the route or direction a bit more.

Ideš is the 2nd person singular present tense of ići, which means to go.

So:

• ja idem = I go / I am going
• ti ideš = you go / you are going
• on/ona/ono ide = he/she/it goes

In this sentence, ideš tells you the subject is you (singular).

Croatian often uses the present tense for actions that are happening soon or are planned, especially when the time is already clear from context.

Because the sentence says poslije posla (after work), Croatian naturally uses ideš.

So Kuda ideš poslije posla? can mean:

• Where are you going after work?
• depending on context, sometimes also Where do you go after work?

Usually the situation tells you whether it is about today’s plan or a habit.

Croatian usually leaves out subject pronouns when they are not needed.

The verb ending already shows who the subject is:

• ideš = you go / you are going

So ti is unnecessary here.

You could add ti only for emphasis or contrast, for example: A ti, kuda ideš poslije posla?
= And you, where are you going after work?

Because poslije requires the genitive case.

The basic form of the noun is:

• posao = work, job

But after poslije, it changes to the genitive singular:

• posla

So:

• posao = work
• poslije posla = after work

This is a very common pattern in Croatian: certain prepositions require specific cases.

It is not completely unpredictable, but it does involve a stem change that learners need to get used to.

The nominative form is posao, but in other forms the -ao disappears:

• posao = nominative
• posla = genitive
• poslu = dative/locative
• poslom = instrumental

So yes, it is a noun you should learn as a pattern rather than trying to guess every form from English.

Yes. Nakon posla is also correct and means the same thing: after work.

So both of these work:

• Kuda ideš poslije posla?
• Kuda ideš nakon posla?

In many situations, poslije sounds more everyday and conversational, while nakon can sound a little more neutral or formal, but both are normal Croatian.

It is informal singular because of ideš.

You would say this to:

• one friend
• one colleague you address informally
• one family member

If you want the formal form, or if you are speaking to more than one person, use idete:

Kuda idete poslije posla?

Yes. Croatian word order is more flexible than English word order.

The most neutral version is:

Kuda ideš poslije posla?

But you could also hear:

Poslije posla kuda ideš?

That version puts more emphasis on after work.

Even when the order changes, the case endings and verb form usually keep the meaning clear.

Yes. Kud is a shorter, very common conversational form of kuda.

So these are both natural:

• Kuda ideš poslije posla?
• Kud ideš poslije posla?

The shorter form is very common in speech. The longer form may sound a bit more careful or standard.

In real life, it can be either, depending on context.

Literally, kuda can point toward which way / by what route. But in everyday conversation, people often use it simply to ask where someone is going.

So if someone says:

Kuda ideš poslije posla?

they will often just mean:

Where are you going after work?

If the route really matters, the surrounding conversation usually makes that clear.
