Koji tip poruke želiš?

Koji means which or what kind of, depending on context.

In this sentence, koji agrees with tip, which is a masculine singular noun. That is why the form is koji.

Some related forms are:

• koji = masculine singular
• koja = feminine singular
• koje = neuter singular

So Koji tip poruke želiš? literally works like Which type of message do you want?

Because Croatian often expresses type of something by using:

• a noun
• followed by another noun in the genitive case

So:

• tip = type
• poruka = message
• poruke = of message / of a message in the genitive singular

That means tip poruke literally means type of message.

This is a very common pattern in Croatian:

• čaša vode = glass of water
• boja auta = color of the car
• vrsta hrane = kind of food

Here, poruke is genitive singular, not plural.

The base noun is:

• poruka = message

Its genitive singular form is:

• poruke = of a message

This can be confusing because poruke is also the nominative plural form, meaning messages. But in this sentence, after tip, it is understood as genitive singular because the structure is type of message.

Želiš means you want.

It comes from the verb željeti = to want.

Here it is:

• 2nd person singular
• present tense

So:

• želim = I want
• želiš = you want
• želi = he/she/it wants

Because Croatian verb endings already show the subject, the pronoun ti (you) is usually not needed.

Croatian usually leaves out subject pronouns when they are already clear from the verb form.

So želiš already tells you the subject is you (singular, informal).

That means:

• Koji tip poruke želiš? and
• Koji tip poruke ti želiš?

both mean roughly the same thing, but the version without ti is more neutral and more common.

Adding ti can give extra emphasis, like Which type of message do you want?

Yes, Croatian word order is fairly flexible, but this version is the most natural and neutral.

The sentence starts with the question phrase:

• Koji tip poruke = what/which type of message

and then the verb:

• želiš = do you want

This is normal for information questions.

Other word orders are possible, but they may sound marked or emphasize something different. For example:

• Koji želiš tip poruke? = also possible, with slightly different focus
• Želiš koji tip poruke? = less neutral, more conversational or marked depending on context

For a learner, Koji tip poruke želiš? is the safest standard version.

In English, both are often possible.

Literally, koji is closer to which, but in natural English, what type of message do you want? may sound more normal in many situations.

So:

• literal translation: Which type of message do you want?
• natural translation: What type of message do you want?

Croatian koji often covers territory that English can express with either which or what.

A rough pronunciation guide for an English speaker is:

• Koji ≈ KO-yi
• tip ≈ teep
• poruke ≈ po-ROO-keh
• želiš ≈ ZHEH-leesh

A few helpful sound notes:

• j in Croatian is like English y in yes
• ž sounds like the s in measure
• š sounds like English sh
• Croatian vowels are usually clear and consistent:
  • a as in father
  • e as in bet (but cleaner)
  • i as in machine
  • o as in more without the glide
  • u as in rule

It is informal singular, because of želiš.

Croatian distinguishes between:

• informal singular: talking to one person you know well
• formal or plural: talking politely or to more than one person

So:

• Koji tip poruke želiš? = informal singular
• Koji tip poruke želite? = formal singular or plural

If you are speaking politely to one person, use želite.

You probably could in some contexts, but it would not mean exactly the same thing.

• koji asks which one
• kakav asks what kind / what sort

So:

• Koji tip poruke želiš? = Which type of message do you want?
• Kakav tip poruke želiš? = more like What kind of message type do you want?

Because the noun tip already means type, koji tip is usually the more natural choice here. Using kakav with tip can feel a bit repetitive in meaning.
