A készpénzfelvétel itt van.

A is the Hungarian definite article, like the in English.

So:

• a készpénzfelvétel = the cash withdrawal

Hungarian has two forms of the:

• a before most consonant sounds
• az before vowel sounds

Here it is a, because készpénzfelvétel begins with a consonant sound.

Hungarian very often forms compound nouns by writing them as a single word.

Here, készpénzfelvétel is made up of:

• készpénz = cash
• felvétel = taking, withdrawal

So together it means cash withdrawal.

This is very normal in Hungarian. What would be several words in English is often one compound word in Hungarian.

Itt means here, and van is the 3rd person singular form of lenni = to be.

So:

• itt van = is here

In this sentence, van works just like is in English.

Structure:

• A készpénzfelvétel = the cash withdrawal
• itt van = is here

So grammatically, it is essentially:

• The cash withdrawal is here.

Because the subject, a készpénzfelvétel, is singular.

Even though the word is long, it is still just one singular noun. So Hungarian uses:

• van = is

If the subject were plural, you would use vannak:

• A bankautomaták itt vannak. = The ATMs are here.

Because it is the subject of the sentence, and Hungarian subjects are usually in the basic dictionary form, called the nominative. Hungarian does not normally mark the nominative with a special ending.

So:

• készpénzfelvétel has no case ending here because it is simply the thing being talked about

If it had another function, it might get an ending. For example:

• készpénzfelvételt = cash withdrawal (as a direct object)

Hungarian word order is flexible, but it is strongly connected to focus and emphasis.

• itt van is the most neutral way to say is here
• van itt is possible in some contexts, but it usually sounds marked or tied to a special emphasis

In A készpénzfelvétel itt van, the location here is simply being stated, so itt van is natural.

Hungarian often puts important information before the verb, and in this sentence itt naturally comes before van.

Yes. That is also grammatical, but the emphasis changes.

Compare:

• A készpénzfelvétel itt van.
  This starts with the cash withdrawal as the topic, then says where it is.

• Itt van a készpénzfelvétel.
  This puts more attention on here first, as if answering Where is the cash withdrawal?

Both can be correct. The difference is mainly one of information structure and emphasis, not basic meaning.

No. They are related, but they do different jobs.

• itt = here (location, being in a place)
• ide = to here (movement toward a place)

So in this sentence you need itt, because the sentence describes location, not motion.

Examples:

• Itt van. = It is here.
• Ide jön. = He/She/It comes here.

It is grammatical, but whether it sounds natural depends on the context.

It can work in a context like:

• pointing out a menu option
• showing where a function is on a screen
• indicating where something labeled cash withdrawal is

In everyday speech, if someone were talking about an ATM function, they might also say something more specific, depending on the situation.

So the sentence is not wrong, but it may sound a bit context-dependent or slightly interface-like if taken by itself.

A helpful approximate breakdown is:

• kész
  • pénz
    • fel
      • vé
        • tel

A few useful points:

• Hungarian stress is normally on the first syllable of the whole word: KÉSZpénzfelvétel
• é is a long vowel, somewhat like the vowel in say, but pure and longer
• sz is pronounced like English s
• z is pronounced like English z

So:

• kész sounds roughly like kays
• pénz roughly like paynz
• felvétel roughly like fel-vay-tel

That is only an approximation, but it can help at first.

It can do both, depending on context.

Most literally, itt van means is here or is present here. But in real use, it can also imply that something is available here, found here, or located here.

So if this sentence appears on a website, app, or machine interface, it may mean something closer to:

• Cash withdrawal is here
• You can find the cash withdrawal option here

The exact nuance comes from the situation, not just the grammar.

Not here.

In Hungarian, the verb to be is often omitted in the present tense with he/she/it or they, but only in sentences where you are linking a subject to a noun or adjective:

• A ház nagy. = The house is big.
• Ő tanár. = He/She is a teacher.

But when you express location, Hungarian normally keeps van:

• A könyv az asztalon van. = The book is on the table.
• A készpénzfelvétel itt van. = The cash withdrawal is here.

So you cannot normally drop van in this sentence.
