Ako želiš saznati točno vrijeme sastanka, javi mi se poslije ručka.

Želiš is the 2nd person singular form of željeti (to want), so it matches you:

• ja želim = I want
• ti želiš = you want
• on/ona želi = he/she wants

So Ako želiš... means If you want...

If you were speaking formally to one person, you would usually say:

• Ako želite...

because Croatian uses the plural/formal form for polite address.

Saznati means to find out / to learn (a piece of information).

It is different from znati, which means to know.

So:

• znati = to know
• saznati = to find out, come to know

In this sentence, Ako želiš saznati... is literally If you want to find out...

This is very natural Croatian. You would not usually use znati here, because the idea is not already knowing, but getting the information.

Because it follows želiš (you want).

Croatian often uses:

• željeti + infinitive

So:

• želim jesti = I want to eat
• želiš doći = you want to come
• želiš saznati = you want to find out

This works much like English want to + verb.

Vrijeme is in the accusative singular, because it is the direct object of saznati (find out).

However, vrijeme is a neuter noun whose nominative and accusative singular look the same:

• vrijeme = nominative singular
• vrijeme = accusative singular

So the form does not change, even though the function does.

In the phrase:

• saznati točno vrijeme sastanka

the thing you want to find out is the exact time of the meeting.

Because vrijeme is a neuter noun.

The adjective must agree with the noun in gender, number, and case:

• točan = masculine
• točna = feminine
• točno = neuter

So:

• točan sastanak = an exact/correct meeting? (not very natural semantically, but grammatically masculine)
• točna informacija = exact/correct information
• točno vrijeme = exact time

Sastanka is the genitive singular of sastanak (meeting).

The phrase vrijeme sastanka literally means:

• time of the meeting

This is a very common Croatian structure: one noun followed by another noun in the genitive to show possession or relation.

Examples:

• vrata kuće = the door of the house / the house door
• ime grada = the name of the city
• vrijeme sastanka = the time of the meeting

So sastanka answers the question whose/which time? → the meeting’s time.

Javi mi se means get in touch with me / contact me / let me know.

It comes from the verb javiti se, which is a very common reflexive expression meaning things like:

• to call/contact someone
• to report back
• to get in touch
• to make oneself heard

The parts are:

• javi = imperative (contact / let know)
• mi = to me
• se = reflexive particle

So literally it is something like:

• contact yourself to me

But you should not translate it word-for-word. As a whole, javi mi se is simply the natural Croatian way to say:

• contact me
• get back to me
• let me know

depending on context.

Because Croatian clitic pronouns usually follow a specific word order.

Both mi and se are clitics, and Croatian has fairly strict rules about where they go. In this kind of sentence, the natural order is:

• javi mi se

not:

• javi se mi

So this is something you should learn as a fixed pattern:

• javi mi se = contact me
• javio mi se = he contacted me
• hoćeš li mi se javiti? = will you contact me?

The short answer is: mi se is the correct clitic sequence here.

Yes. Javi is the 2nd person singular imperative of javiti (se).

So it is directed at one person informally:

• javi mi se = contact me / get in touch with me

If you wanted the formal or plural version, you would say:

• javite mi se

So the whole sentence is informal because it uses:

• želiš
• javi

both addressed to ti.

After poslije, Croatian uses the genitive.

So:

• ručak = lunch
• ručka = genitive singular

That is why you get:

• poslije ručka = after lunch

Other examples:

• poslije škole = after school
• poslije posla = after work
• poslije sastanka = after the meeting

Yes. Poslije ručka and nakon ručka both mean after lunch.

Both take the genitive.

Very roughly:

• poslije is extremely common in everyday speech
• nakon can sound a bit more neutral or slightly more formal in some contexts

In this sentence, both are fine:

• javi mi se poslije ručka
• javi mi se nakon ručka

Because Croatian often uses the present tense after ako (if) when talking about a future possibility.

So:

• Ako želiš, javi mi se.
• literally: If you want, contact me.

This is normal Croatian. English often behaves similarly:

• If you want to find out..., contact me later.

Croatian does not need a future form here. The present is enough because the conditional meaning is already clear from ako.

Yes, to some extent. Croatian word order is flexible, although some versions sound more natural than others.

The original sentence is very natural:

• Ako želiš saznati točno vrijeme sastanka, javi mi se poslije ručka.

You could also say:

• Javi mi se poslije ručka ako želiš saznati točno vrijeme sastanka.

This changes the emphasis slightly, but the meaning stays the same.

What you usually should not change carelessly is the internal clitic order in javi mi se.

It is informal, because it uses ti forms:

• želiš
• javi

To make it formal or plural, you would say:

• Ako želite saznati točno vrijeme sastanka, javite mi se poslije ručka.

So:

• želiš / javi = informal singular
• želite / javite = formal singular or plural

Because Croatian has no articles like English a/an/the.

So Croatian simply says:

• vrijeme sastanka
• poslije ručka

and the listener understands from context whether it means:

• the time of the meeting
• after lunch
• after the lunch

In this sentence, the context naturally gives the definite meaning in English:

• the exact time of the meeting
• after lunch
