A szivárgás itt van.

A is the definite article, so it means the.

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

Since szivárgás starts with sz, which is a consonant sound, the correct form is a szivárgás.

Szivárgás is a noun meaning leak, leakage, or seepage, depending on context.

It is related to the verb szivárog, which means to leak or to seep.

So in this sentence, a szivárgás means the leak or the leakage.

That is a very common question, because Hungarian does often omit the verb to be in the present tense.

For example:

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

But when you are talking about location or existence, Hungarian normally keeps van:

• A ház itt van. = The house is here.
• A könyv az asztalon van. = The book is on the table.

So A szivárgás itt van correctly includes van because the sentence says where something is.

Itt means here.

It refers to a location near the speaker.

A useful comparison:

• itt = here
• ott = there

And if you want direction rather than location:

• ide = to here
• innen = from here

So itt van means is here.

Hungarian word order is flexible, and it often shows topic and emphasis rather than following a fixed English-style pattern.

In A szivárgás itt van:

• A szivárgás is the topic: the leak
• itt van is what is being said about it: is here

So this is a natural way to say The leak is here.

If you change the order to Itt van a szivárgás, the meaning is similar, but the location here gets more attention, something like Here is the leak or The leak is here with stronger emphasis on here.

Yes, you can.

Both are possible, but they are not identical in emphasis:

• A szivárgás itt van. = neutral statement about the leak; the leak is here
• Itt van a szivárgás. = stronger focus on the location; the leak is here / here is the leak

So the difference is mainly about what you want to highlight.

No. Van is the 3rd person singular form of lenni, to be, but it is used in several related ways.

It can mean:

• is
• exists
• there is

For example:

• A szivárgás itt van. = The leak is here.
• Itt van egy probléma. = There is a problem here.

So in Hungarian, van covers several uses that English often separates.

A rough pronunciation guide is:

aw SEE-vaar-gaash itt vawn

A few important points:

• sz is pronounced like English s, not z
• Hungarian s by itself sounds like English sh
• á is a long vowel, somewhat like the a in father, but longer
• tt is pronounced as a clearly long t
• stress in Hungarian normally falls on the first syllable of each word

So:

• A
• SZI-vár-gás
• ITT
• van

It is singular.

So A szivárgás itt van refers to one leak or one instance of leakage.

The plural would be szivárgások.

Usually, no, not in normal neutral speech.

If you mean the leak, Hungarian normally uses the definite article:

• A szivárgás itt van.

Without a, the sentence sounds unusual, incomplete, or specially marked unless it appears in a very specific context such as a note, headline, or stylized speech.

So for ordinary usage, a szivárgás is the expected form.
