Poništite pogrešno pitanje.

Poništite is the imperative form of the verb poništiti. In other words, it is a command: cancel, invalidate, annul, or undo.

So the sentence is giving an instruction to do something to pogrešno pitanje.

The ending -te is used for:

• a command to more than one person
• a polite/formal command to one person

So Poništite can mean:

• Cancel ... when speaking politely to one person
• Cancel ... when speaking to several people

If you were speaking informally to just one person, you would usually say Poništi.

Yes. The form poništite can also be the 2nd person plural present form of poništiti.

However, in a short standalone sentence like this, especially as an instruction, it is naturally understood as an imperative.

This is very common in Croatian: the form itself can match another tense, but the context makes the meaning clear.

Because pitanje is a neuter noun, and adjectives in Croatian must agree with the noun in gender, number, and case.

The adjective pogrešan changes like this in the singular:

• masculine: pogrešan
• feminine: pogrešna
• neuter: pogrešno

Since pitanje is neuter, the correct form is pogrešno pitanje.

Here it is an adjective, because it describes the noun pitanje.

So:

• pogrešno pitanje = wrong/incorrect question

But pogrešno can also be an adverb in other sentences, for example:

• Pogrešno ste odgovorili. = You answered incorrectly.

So the word itself can have different jobs, but in this sentence it is clearly an adjective.

It is in the accusative singular, because it is the direct object of the verb poništite.

You are canceling what?
→ pogrešno pitanje

A useful thing to know is that many neuter singular nouns in Croatian have the same form in the nominative and accusative. So pitanje looks unchanged, even though it is functioning as the object.

Because Croatian has no articles like a, an, or the.

So pogrešno pitanje can mean:

• a wrong question
• the wrong question

The exact meaning depends on the situation and context.

This is something English speakers often have to get used to, because English requires an article much more often than Croatian does.

No, Croatian word order is fairly flexible.

Poništite pogrešno pitanje is a natural, neutral way to give the instruction. But other word orders are possible, especially for emphasis.

For example:

• Poništite pogrešno pitanje = neutral instruction
• Pogrešno pitanje poništite = more marked; extra emphasis on the wrong question

So the given order is normal, but not the only possible one.

Poništiti has the sense of making something invalid, void, or canceled.

Depending on context, Croatian might also use other verbs, such as:

• izbrisati / obrisati = delete, erase
• ukloniti = remove
• otkazati = cancel

So poništiti is not the only possible verb in all situations. It is especially suitable when something is being formally canceled, nullified, or invalidated.

Poništiti is a perfective verb. That means it presents the action as a completed whole.

That fits this sentence well, because the instruction is about doing one complete action: cancel the question.

In Croatian, perfective verbs are very common in commands when the speaker wants the action to be completed. An imperfective form would sound more like repeated, ongoing, or habitual action, which is usually not what is meant here.

A few sounds may stand out for English speakers:

• š sounds like sh in ship
• nj sounds roughly like ny in canyon
• č / ć do not appear here, so you do not need to worry about them in this sentence

So roughly:

• poništite ≈ po-NISH-ti-te
• pogrešno ≈ po-GRESH-no
• pitanje ≈ PI-ta-nye

These are only rough English approximations, but they help with the main sounds. The most important thing is to pronounce š as sh and nj as ny.
