Egyetlen frissítőpont van.

Hungarian leaves out van in the 3rd person present only in simple sentences like A víz hideg = The water is cold or Ez egy könyv = This is a book.

But Egyetlen frissítőpont van is an existential sentence: it means that something exists / is available. In that type of sentence, van is normally required.

So here van means something like there is / exists.

Hungarian does not use a dummy subject like English there in this kind of sentence. The idea of there is / there exists is expressed mainly by van and by the sentence structure.

So the sentence is more literally like:

Only one refreshment point exists.

Not every English word has a direct Hungarian counterpart.

egyetlen is stronger than plain egy.

It usually means:

• a single
• only one
• one and only

So egyetlen frissítőpont van does not just say that there is one refreshment point; it emphasizes that there is only one.

Because egyetlen is already acting as the determiner of the noun. It fills the same slot where you might otherwise have egy.

So:

• egy frissítőpont = a refreshment point
• egyetlen frissítőpont = a single / only one refreshment point

You would not normally add another article before it.

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

Here:

• frissítő = refreshment / something refreshing
• pont = point

Together, frissítőpont means refreshment point, refreshment station, or something similar depending on context.

English often writes such combinations as two words, but Hungarian frequently uses one word.

After egyetlen, the noun is singular.

More generally, Hungarian usually keeps the noun in the singular after numbers as well:

• egy frissítőpont = one refreshment point
• két frissítőpont = two refreshment points

So this is normal Hungarian grammar. English uses the plural after numbers greater than one, but Hungarian usually does not.

In Hungarian, the position right before the verb is often the focus position. That means the speaker is highlighting that part of the sentence.

By putting egyetlen frissítőpont before van, the sentence strongly emphasizes the idea only one refreshment point.

So the sentence is not just stating existence; it is also stressing the number.

Yes. Csak egy frissítőpont van is very natural and very close in meaning.

The difference is mostly one of style and emphasis:

• csak egy = straightforward only one
• egyetlen = a single / only one, often a bit more compact or emphatic

In many contexts, they can be translated the same way.
