A nevezés nyitva van.

Here nevezés means registration, entry, or sign-up, depending on context.

It is especially common with:

• competitions
• races
• tournaments
• contests
• events where you enter as a participant

So A nevezés nyitva van. is a natural way to say Registration is open or Entries are open.

Be careful: the verb behind it, nevez(ni), can also relate to naming/calling in other contexts, so the noun nevezés does not always mean registration. In this sentence, though, that is clearly the intended meaning.

It comes from the verb nevezni and the noun-forming suffix -és.

A very common Hungarian pattern is:

• verb stem + -ás / -és → action noun

So:

• nevezni → nevezés

This often works like English -ing or nouns like registration, application, opening, depending on the word.

A is the definite article, meaning the.

Hungarian often uses the definite article in places where English does not. In this sentence, a nevezés refers to the specific registration process for the event being discussed, so using the article is natural.

Without the article, Nevezés nyitva van would sound unnatural in standard Hungarian.

Hungarian has two forms of the definite article:

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

Since nevezés begins with n, a consonant, the correct form is a nevezés.

Examples:

• a bolt = the shop
• az iskola = the school

Literally, it means something like is in an open state.

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

So the whole sentence is literally close to:

The registration is open.

This is the normal Hungarian way to say that something is currently open and available.

Nyitva is a -va/-ve form, often called an adverbial participle in grammar explanations.

It comes from the verb nyitni (to open).

So:

• nyitni = to open
• nyitva = opened / being in an open state

This form is very common in Hungarian when describing a resulting state:

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

That is a very common question.

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

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

But nyitva is not behaving like a simple ordinary adjective here. It is this -va/-ve state form, and with that form Hungarian normally keeps van:

• Az ajtó nyitva van.
• A bolt zárva van.
• A nevezés nyitva van.

So in this sentence, van is required in standard Hungarian.

Both can relate to open, but they are not used in exactly the same way.

nyitva van

• usually means something is currently open
• often used for doors, shops, offices, registration, applications, etc.
• emphasizes the state

nyitott

• is a more ordinary adjective meaning open
• can describe something in a more general or descriptive way
• can also mean open-minded, receptive, not closed off, depending on context

For something like Registration is open, nyitva van is the most natural everyday phrasing.

Yes, absolutely.

Both are grammatical:

• A nevezés nyitva van.
• Nyitva van a nevezés.

The difference is mainly emphasis.

• A nevezés nyitva van. = neutral statement; topic first
• Nyitva van a nevezés. = puts more attention on open

Hungarian word order is flexible and often reflects what is being emphasized or presented as new information.

No. Hungarian has several words that can correspond to English registration, depending on the situation.

Common ones include:

• nevezés = entry/registration, especially for competitions and events
• jelentkezés = application, sign-up
• regisztráció = registration, especially formal or technical contexts

So A nevezés nyitva van. is especially suitable when talking about entering an event, race, contest, or similar activity.

Yes, it sounds natural.

It is a normal, standard way to say that registration or entry is currently open. You would see or hear similar sentences on:

• event websites
• race announcements
• competition pages
• posters
• online forms

It is short, clear, and idiomatic.
