Az ügyintéző letiltja a bankkártyát.

Hungarian has two forms of the definite article:

• a before a consonant sound
• az before a vowel sound

Since ügyintéző starts with a vowel sound, the correct form is az ügyintéző.

Compare:

• az ügyintéző
• a bankkártya

Ügyintéző is a common word for a person who handles administrative matters, paperwork, customer cases, or official business.

Depending on context, it can be translated as:

• clerk
• administrator
• case officer
• customer service representative
• official

So it is not just any employee; it usually suggests someone whose job is to process or handle an issue.

Because it is the direct object of the verb, and Hungarian marks direct objects with the accusative ending -t.

• base form: bankkártya
• object form: bankkártyát

Also notice this common change:

• final -a often becomes long -á- before certain suffixes

So:

• bankkártya → bankkártyát

This is very common in Hungarian:

• szoba → szobát
• kutya → kutyát

The verb here is letiltja, from letilt.

The prefix le- changes the meaning of the verb. On its own, tilt is related to forbidding or prohibiting, but letilt often means something like:

• block
• disable
• deactivate
• bar access to

With things like bank cards, accounts, phones, or services, letilt is a very natural verb.

So letiltja a bankkártyát means that the card is being blocked or deactivated.

Because Hungarian verbs have two kinds of conjugation:

• indefinite
• definite

Here the object is specific and definite: a bankkártyát = the bank card.
When the object is definite, Hungarian normally uses the definite conjugation.

That is why we get:

• letiltja = he/she blocks it

Compare:

• Az ügyintéző letilt egy bankkártyát.
  The clerk blocks a bank card.
  → indefinite object → letilt

• Az ügyintéző letiltja a bankkártyát.
  The clerk blocks the bank card.
  → definite object → letiltja

Letiltja is:

• third person singular
• present tense
• definite conjugation

So it means he/she blocks it or the clerk blocks it.

In context, Hungarian present tense can also sometimes refer to a near future action, especially if the situation makes that clear. So depending on context, it might also be understood as something like will block.

Yes, but Hungarian word order is more flexible than English word order.

Az ügyintéző letiltja a bankkártyát is a neutral sentence. It presents the action in a straightforward way.

Hungarian word order often reflects topic and focus, not just grammar. So other orders are possible, but they change emphasis.

For example:

• A bankkártyát az ügyintéző tiltja le.
  This can put more focus on who is blocking it.

• Az ügyintéző a bankkártyát tiltja le.
  This can emphasize the bank card as the thing being blocked.

Also, with verbal prefixes like le-, the prefix often stays attached in neutral statements, but it can move away from the verb when something else is focused.

Yes. In the neutral form, the verbal prefix usually stays directly before the verb:

• letiltja

But in Hungarian, prefixes can separate from the verb in certain situations, especially with:

• focus
• negation
• some question patterns

For example:

• Az ügyintéző nem tiltja le a bankkártyát.
  The clerk does not block the bank card.

Here le- moves away because of negation.

So in your sentence, letiltja is the normal neutral arrangement.

A few useful pronunciation points:

• Stress in Hungarian is always on the first syllable of the word.
• So you get:
  • AZ ügyintéző
  • BANKkártyát
  • LEtiltja

Some specific sounds:

• ü is a rounded front vowel, somewhat like the German ü
• gy is a soft consonant, roughly like the dy sound in British duke for many speakers
• é is a long vowel, roughly like ay in say, but pure and steady
• ő is a long rounded vowel, again similar to German or Turkish front rounded vowels

A rough learner-friendly pronunciation guide might be:

• az ügyintéző ≈ az üdyin-tay-ző
• bankkártyát ≈ bank-kaar-tyaat
• letiltja ≈ leh-til-tya

That is only approximate, but it helps as a starting point.

Not necessarily. Bankkártya is a general everyday word for a bank card. Depending on context, it may refer to:

• a debit card
• a credit card
• sometimes just a payment card linked to a bank account

If Hungarian needs to be more specific, speakers can use more precise terms, but bankkártya is often enough in normal conversation.
