Imaš li nekakav plan za večeras?

Imaš is the 2nd person singular present tense of imati = to have.

So here:

• imaš = you have

In this sentence, it is used in the everyday sense of Do you have... ?, meaning:

• Do you have some kind of plan for tonight?
• more naturally in English: Do you have any plans for tonight?

Croatian often uses imati in the same kinds of situations where English uses to have.

Li is a question particle. It helps turn the sentence into a yes/no question.

So:

• Imaš nekakav plan za večeras. = You have some kind of plan for tonight.
• Imaš li nekakav plan za večeras? = Do you have some kind of plan for tonight?

This is a very common pattern in Croatian:

• Radiš li sutra? = Are you working tomorrow?
• Znaš li to? = Do you know that?
• Možeš li doći? = Can you come?

A useful thing to remember: li usually comes right after the first stressed word, and in this sentence that word is imaš.

Yes. Da li imaš... ? is also used to ask yes/no questions.

So both are possible:

• Imaš li nekakav plan za večeras?
• Da li imaš nekakav plan za večeras?

However, many learners are taught that verb + li is the more standard and often more elegant written form:

• Imaš li...?

while da li is also very common in speech.

So if you want a solid general pattern, Imaš li...? is an excellent one to learn.

Because Croatian usually does not need subject pronouns when the verb already shows who the subject is.

• imaš already means you have
• so ti = you is unnecessary unless you want emphasis

Compare:

• Imaš li nekakav plan za večeras? = normal, neutral
• Ti imaš li nekakav plan za večeras? = unusual in most normal contexts
• Imaš li ti nekakav plan za večeras? = possible if you want emphasis, contrast, or a specific tone

In everyday Croatian, leaving out the pronoun is completely normal.

Nekakav means something like:

• some kind of
• some sort of
• sometimes just any kind of

So nekakav plan literally suggests:

• some kind of plan
• any sort of plan

It is similar to neki, but not exactly the same.

• neki plan = some plan
• nekakav plan = some kind of plan / any sort of plan

In this sentence, nekakav can give a slightly casual, loose feeling, as if the speaker means:

• Do you have anything in mind for tonight?
• Do you have any sort of plan for tonight?

So it sounds a bit less formal and a bit more conversational than a plain neki plan.

Good question. Croatian often uses the singular where English naturally prefers the plural.

So:

• nekakav plan literally = some kind of plan
• but natural English translation is often any plans

This is completely normal. Croatian is not forced to match English number word-for-word.

So even though the Croatian says plan singular, the most natural English meaning may be:

• Do you have any plans for tonight?

not necessarily:

• Do you have some kind of plan for tonight?

Both are possible translations depending on tone.

Plan is in the accusative singular, but because plan is an inanimate masculine noun, its accusative form is the same as its nominative form.

So:

• nominative: plan
• accusative: plan

Why accusative? Because it is the direct object of imaš:

• You have what?
• plan

That makes it the object, so accusative is expected.

Za večeras means:

• for tonight
• literally: for this evening

Breakdown:

• za = for
• večeras = this evening / tonight

So:

• plan za večeras = a plan for tonight

This is a very common use of za in Croatian when talking about something intended for a time or occasion:

• Što imaš za sutra? = What do you have for tomorrow?
• Plan za vikend = a plan for the weekend
• Nešto za večeru = something for dinner

Večeras is best understood as an adverbial time expression meaning:

• tonight
• this evening

It is not behaving like a normal noun here.

Compare:

• večer = evening (noun)
• večeras = tonight / this evening (time expression)

Examples:

• Dolazim večeras. = I’m coming tonight.
• Što radiš večeras? = What are you doing tonight?

In your sentence, za večeras means for tonight.

It is informal, because imaš is the singular you form, used with:

• friends
• family
• peers
• people you know well
• children

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

• Imate li nekakav plan za večeras?

That can mean either:

• Do you have any plans for tonight? addressing one person formally
• Do you all have any plans for tonight? addressing more than one person

So:

• imaš = informal singular you
• imate = formal singular or plural you

Yes, you can. But the nuance changes a little.

• Imaš li nekakav plan za večeras? = Do you have any sort of plan for tonight?
• Imaš li plan za večeras? = Do you have a plan for tonight?

The version with nekakav sounds a bit more open-ended, casual, and flexible. It can suggest:

• Do you have anything in mind?

Without nekakav, the sentence can sound slightly more direct, as if the speaker is asking whether there is a specific plan.

Both are correct.

Yes. Kakav plan and nekakav plan can both appear in similar contexts.

• Imaš li kakav plan za večeras?
• Imaš li nekakav plan za večeras?

Both can mean something like:

• Do you have any kind of plan for tonight?

The exact nuance depends on region, style, and speaker preference. In many everyday situations, both sound natural. A learner should mainly understand that kakav and nekakav in these kinds of questions often do not always mean a very literal what kind of; they can function more loosely like any kind of.

A very literal translation is:

• Do you have some kind of plan for tonight?

But in natural English, people would more often say:

• Do you have any plans for tonight?
• Do you have anything planned for tonight?
• Got any plans for tonight? (very casual)

So if you are trying to understand the Croatian naturally, think of it as an everyday question about whether someone already has arrangements for the evening.

A simple learner-friendly pronunciation guide would be:

• Imaš li nekakav plan za večeras?
• approximately: EE-mash lee NE-ka-kav plan za ve-CHE-ras

A few helpful notes:

• š sounds like sh in ship
• č sounds like ch in church
• c in Croatian is usually ts
• r is rolled or tapped

The exact stress can vary a little by region, but for a learner the most important thing is to pronounce the sounds clearly and keep li unstressed.

A few natural answers are:

• Nemam. = I don’t.
• Nemam nikakav plan. = I don’t have any plan.
• Nemam ništa u planu za večeras. = I don’t have anything planned for tonight.
• Ne još. = Not yet.

And a positive answer could be:

• Imam. = I do.
• Imam plan. = I have a plan.
• Da, idem van. = Yes, I’m going out.

So this sentence is a very normal conversation starter.
