A kormányablak ma nyitva van.

Literally, kormány means government and ablak means window, so the compound literally looks like government window.

But in modern Hungarian, kormányablak is the name of a government customer service office, where people handle official paperwork. So in real use, it means something like:

• government service office
• government help desk
• one-stop administrative office

So the sentence is not about a physical window in a building. It is about the office being open.

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

Here:

• kormány = government
• ablak = window

Together they form one established compound: kormányablak.

This is very common in Hungarian. English often uses separate words where Hungarian prefers a single compound.

Hungarian has two forms of the definite article:

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

Since kormányablak begins with k, a consonant, the correct article is a:

• a kormányablak

If the next word began with a vowel, you would use az instead.

In Hungarian, the definite article is used very naturally when talking about a specific, identifiable thing.

So A kormányablak ma nyitva van most naturally means:

• The government office is open today

It can refer to:

• the specific office already known from context, or
• the local office that both speaker and listener can identify

Hungarian often uses the definite article in places where English might or might not, depending on context.

Ma means today.

It is a time adverb, and here it tells you when the office is open:

• A kormányablak ma nyitva van.
• The government office is open today.

It has no ending here; ma is simply the basic form of the word.

This is one of the most important things in the sentence.

Nyitva van is a very common Hungarian structure meaning is open in the sense of being in an open state.

• nyitva = open, in an open state
• van = is

So together:

• nyitva van = is open

This pattern is extremely common:

• Az ajtó nyitva van. = The door is open.
• A bolt nyitva van. = The shop is open.
• Az iroda zárva van. = The office is closed.

So learners should treat nyitva van almost as a fixed expression.

That is a very common and very good question.

Hungarian often omits the present-tense forms of to be in sentences like:

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

But in expressions like nyitva van, zárva van, rendben van, the verb van is normally kept.

So:

• A kormányablak ma nyitva van. = correct
• A kormányablak ma nyitva. = usually not the normal full form here

That is because nyitva is not behaving like a simple adjective in the same way as nagy. It is part of a state expression.

For businesses, offices, doors, shops, and similar things, Hungarian usually uses nyitva for the state open.

So:

• A bolt nyitva van. = The shop is open.
• Az ajtó nyitva van. = The door is open.

Nyitott exists too, but it is not the normal choice here. It often feels more like:

• opened
• open-minded / receptive in some contexts
• or an adjective describing something as open in a broader sense

For a store or office being open for business, nyitva van is the standard expression.

Yes, you can say:

• A kormányablak ma nyitva van.
• Ma a kormányablak nyitva van.

Both are natural.

The difference is mainly emphasis and information structure:

• A kormányablak ma nyitva van.
  Neutral; the topic is the government office, and you add that today it is open.

• Ma a kormányablak nyitva van.
  Puts today first, so it sounds more like As for today, the government office is open.

Hungarian word order is flexible, but the different orders usually signal different emphasis rather than random variation.

Yes, it can.

Even without extra words, ma can sometimes suggest a contrast depending on context:

• A kormányablak ma nyitva van.
• The government office is open today.

In the right situation, this may imply:

• maybe it is usually closed today
• maybe it was closed yesterday
• maybe someone was unsure whether it would be open

The sentence itself does not force that contrast, but context can make it feel that way.

You would normally say:

• A kormányablak ma nincs nyitva.
• The government office is not open today.

Notice that van changes to nincs in the negative.

Another very common way is:

• A kormányablak ma zárva van.
• The government office is closed today.

Both are possible, but zárva van is often the more natural way to say the office is closed.

A rough pronunciation guide is:

• kormányablak ≈ KOHR-maany-awb-lawk

A few useful points:

• á is a long vowel, somewhat like the vowel in father
• ny sounds like the ny in canyon
• stress in Hungarian is always on the first syllable, so: KÓR-mány-ablak

A more careful breakdown:

• kór
• mány
• ab
• lak

Yes. It is completely natural and idiomatic.

It is short, clear, and typical of the kind of sentence you would see or hear in practical contexts, such as:

• asking about office hours
• checking whether a government office is open
• reading a notice or website

So as a learner, this is a very useful model sentence:

• A hely ma nyitva van. = The place is open today.
• Az iroda ma zárva van. = The office is closed today.
• A bolt hétfőn nyitva van. = The shop is open on Monday.
