Az iskolai uszoda nyitva van.

Az is the definite article, meaning the.

Hungarian has two forms of the definite article:

• a before most consonant sounds
• az before vowel sounds

Since iskolai begins with a vowel sound, Hungarian uses az:

• az iskolai uszoda = the school swimming pool

So this is not a special word with a special meaning here; it is just the normal definite article.

Iskola means school as a noun.

The form iskolai is an adjective meaning something like:

• school
• school-related
• belonging to the school

The suffix -i often turns a noun into an adjective.

So:

• iskola = school
• iskolai uszoda = school swimming pool / the swimming pool of the school

This is very common in Hungarian:

• város = city

• városi = city / urban

• ország = country
• országi = national / of a country

Here, iskolai describes uszoda.

Uszoda means swimming pool or swimming facility.

In many contexts, it refers not just to the water itself, but to the whole pool building or public swimming place.

So az iskolai uszoda is most naturally understood as:

• the school swimming pool
• the school pool
• sometimes the school swimming facility

Nyitva van is a very common Hungarian way to express the state is open.

It is made of:

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

Together:

• nyitva van = is open

This pattern is very common in Hungarian for states:

• zárva van = is closed
• kinyitva van = is opened / has been opened
• becsukva van = is shut

So in this sentence:

• Az iskolai uszoda nyitva van. = The school swimming pool is open.

That is a very good question.

In Hungarian, the verb van is often omitted in the present tense in the 3rd person when the predicate is a noun or adjective:

• A ház nagy. = The house is big.
• Péter tanár. = Peter is a teacher.

But with forms like nyitva, zárva, bezárva, elromolva, Hungarian commonly uses van:

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

So nyitva van is the normal full form here.

In casual speech, people may sometimes shorten it, but for learners, nyitva van is the standard form to remember.

It behaves a bit differently from a basic adjective.

For learning purposes, it is easiest to think of nyitva as a state form meaning open. It is commonly used with van:

• nyitva van = is open
• zárva van = is closed

This is slightly different from ordinary adjectives like:

• nagy = big
• szép = beautiful

So although in English we simply say open, in Hungarian the usual expression is the set phrase nyitva van.

This is the most neutral, straightforward word order:

• Az iskolai uszoda = the topic / what we are talking about
• nyitva van = the comment / what is being said about it

So it simply means:

• The school pool is open.

Hungarian word order can change for emphasis. For example:

• Nyitva van az iskolai uszoda.

This still means the same thing, but it may sound more like:

• The school pool is open
• or The school pool is indeed open

The original sentence is the plain neutral version.

Because the whole phrase is one noun phrase:

• az = the
• iskolai = school
• uszoda = swimming pool

So az belongs to the entire phrase iskolai uszoda.

Hungarian does not need an article before both words. It works like English:

• the school pool
• not the school the pool

Yes. That is a very natural English translation.

Iskolai uszoda can often be understood as:

• school swimming pool
• the school’s swimming pool
• the swimming pool belonging to the school

The exact English phrasing depends on context, but the Hungarian sentence itself is perfectly natural.

A rough pronunciation guide for an English speaker is:

• az ≈ awz
• iskolai ≈ EESH-ko-law-ee
• uszoda ≈ OO-so-daw
• nyitva ≈ NYEE-tvaw
• van ≈ vawn

A few important points:

• s in Hungarian is pronounced like English sh
• sz in Hungarian is pronounced like English s
• ny is like the ny in canyon
• stress is always on the first syllable of each word

So the sentence is stressed roughly like this:

• AZ ISkolai USZoda NYITva van

Uszoda is in the nominative singular, which is the basic dictionary form.

There is no special case ending here because it is the subject of the sentence:

• Az iskolai uszoda = the school swimming pool

If it were in another role, it might take a case ending:

• az iskolai uszodában = in the school swimming pool
• az iskolai uszodát = the school swimming pool (object)

But in your sentence, it is just the subject.

Yes, and this is a useful distinction.

In many everyday situations:

• nyitva van means is open as a state
• nyitott can mean open, but often feels more adjective-like

For example:

• A bolt nyitva van. = The shop is open.
• A kapu nyitott. = The gate is open.

But for shops, offices, pools, and opening hours, nyitva van is especially common and natural.

So in this sentence, nyitva van is exactly what learners should expect.

Yes, very often.

Examples:

• A bolt nyitva van. = The shop is open.
• Az ajtó nyitva van. = The door is open.
• A könyvtár nyitva van. = The library is open.
• A múzeum zárva van. = The museum is closed.

So nyitva van / zárva van is a very common pattern worth learning as a chunk.
