A könyvtáros itt van.

A is the definite article, so it means the.

So a könyvtáros = the librarian.

Hungarian has two forms of the definite article:

• a before most consonant sounds
• az before vowel sounds

For example:

• a könyvtáros = the librarian
• az orvos = the doctor

Because a könyvtáros means the librarian, a specific librarian.

If you wanted to say a librarian in the indefinite sense, you would say:

• egy könyvtáros

So the contrast is:

• a könyvtáros = the librarian
• egy könyvtáros = a librarian

Könyvtáros means librarian.

It is related to könyvtár, which means library. So this is a useful word family:

• könyv = book
• könyvtár = library
• könyvtáros = librarian

A rough English-friendly guide is:

KÖNYV-taa-rosh

A few important sounds:

• ö is a rounded vowel, somewhat like the vowel in French peu or German schön
• ny is like the ny in canyon
• á is a long a, like a longer open vowel
• final s in Hungarian is pronounced like English sh

So könyvtáros ends with a sh sound, not an s sound.

Itt means here.

It is a common adverb of place. Compare:

• itt = here
• ott = there

So:

• A könyvtáros itt van. = The librarian is here.
• A könyvtáros ott van. = The librarian is there.

That is a very common and very good question.

In Hungarian, the present tense of to be is often omitted in the 3rd person singular when linking a subject to a noun or adjective:

• A könyvtáros fáradt. = The librarian is tired.
• A könyvtáros okos. = The librarian is smart.

But with adverbs of place like itt and ott, Hungarian normally keeps van:

• A könyvtáros itt van. = The librarian is here.
• A könyvtáros ott van. = The librarian is there.

So this sentence needs van.

No, not in standard Hungarian.

With location words like itt and ott, you normally need van in the 3rd person singular.

So the natural form is:

• A könyvtáros itt van.

Not:

• A könyvtáros itt

Van is the 3rd person singular present form of the verb lenni, which means to be.

So here it means is:

• van = is

Some useful related forms are:

• vagyok = I am
• vagy = you are
• van = he/she/it is
• vagyunk = we are
• vagytok = you are plural
• vannak = they are

Hungarian does not mark grammatical gender in nouns the way many European languages do.

So könyvtáros can mean:

• a male librarian
• a female librarian

The sentence itself does not tell you the gender. You would only know from context.

This is one major difference from English, where he and she are different. Hungarian uses ő for both he and she.

Yes. Hungarian word order is flexible, and different orders can change the focus or emphasis.

The neutral sentence is:

• A könyvtáros itt van.

You can also say:

• Itt van a könyvtáros.

This still means roughly The librarian is here or Here is the librarian, but it puts more attention on here or on the librarian’s presence at this location.

So both are possible, but they are not always identical in emphasis.

Because Hungarian nouns usually have no special nominative ending for the basic subject form.

So könyvtáros by itself can serve as the subject:

• A könyvtáros itt van.

Many meanings that English expresses with word order or prepositions are shown in Hungarian with case endings, but the plain subject form often has no ending.

This sentence is singular:

• A könyvtáros itt van. = The librarian is here.

The plural would be:

• A könyvtárosok itt vannak. = The librarians are here.

Notice both parts change:

• könyvtáros → könyvtárosok
• van → vannak

Yes, very common.

You can use the same pattern with many nouns:

• Anya itt van. = Mom is here.
• A tanár itt van. = The teacher is here.
• Péter itt van. = Péter is here.

So this sentence is a good model for talking about someone’s presence in a place.
