A vendéglista teljes.

A is the Hungarian definite article, so here it means the.

Hungarian has two forms of the definite article:

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

Since vendéglista begins with v, which is a consonant, the correct form is a vendéglista.

Compare:

• a könyv = the book
• az asztal = the table

In Hungarian, the verb to be is usually left out in the present tense, third person singular when the sentence says that something is something or is some quality.

So:

• A vendéglista teljes. = The guest list is complete.

There is no separate word for is here, even though English requires it.

But in other persons, Hungarian does use the verb:

• Én fáradt vagyok. = I am tired.
• Te fáradt vagy. = You are tired.

And in past or future tense, van/volt/lesz-type forms appear as needed.

Here, teljes is a predicate adjective, not an adjective directly attached to the noun inside the noun phrase.

So the structure is:

• A vendéglista = the guest list
• teljes = complete

Together: The guest list is complete.

If you put the adjective before the noun, it becomes part of the noun phrase instead:

• a teljes vendéglista = the complete guest list

So there is an important difference:

• A vendéglista teljes. = The guest list is complete.
• A teljes vendéglista... = The complete guest list...

Yes, vendéglista is one compound word.

It is made from:

• vendég = guest
• lista = list

So literally it is guest-list, just like English guest list.

Hungarian often writes compounds as a single word where English may use two words.

It is in the nominative form, which is the basic dictionary form.

There is no special ending on it here because it is the subject of the sentence.

• A vendéglista teljes. = The guest list is complete.

If it were the object of a verb, you would often see the accusative ending -t:

• Látom a vendéglistát. = I see the guest list.

Notice how vendéglista becomes vendéglistát there.

No. Hungarian adjectives do not agree with nouns for gender, because Hungarian has no grammatical gender.

In predicate position, the adjective also does not change for singular/plural in the way learners of some European languages might expect.

So:

• A vendéglista teljes. = The guest list is complete.
• A vendéglisták teljesek. = The guest lists are complete.

In the plural sentence, the adjective can take a plural ending (teljesek) because the subject is plural. But there is still no gender agreement like masculine/feminine/neuter.

Yes, you could.

Hungarian word order is flexible, and moving elements can change the focus or emphasis.

• A vendéglista teljes. is a neutral statement.
• Teljes a vendéglista. can sound more like The guest list is complete with emphasis on complete.

So both are possible, but the version with A vendéglista first is the more straightforward neutral pattern for beginners to learn.

A rough English-friendly guide:

• a = short aw
• vendéglista ≈ VEN-dayg-lee-staw
• teljes ≈ TEHY-yesh

A few helpful points:

• é is a long vowel, roughly like ay in careful pronunciation
• j is pronounced like English y
• s is pronounced like English sh
• sz would be English s, but there is no sz in this sentence

So teljes sounds roughly like tel-yesh, not like English tell-jess.

Teljes often means:

• complete
• full
• entire
• sometimes total

The best translation depends on context.

In A vendéglista teljes, complete is the most natural choice, because a guest list is something that can be unfinished and then complete.

In other contexts:

• teljes név = full name
• teljes nap = whole day / full day
• teljes összeg = full amount / total amount

In normal Hungarian, you would usually say A vendéglista teljes.

The definite article is used because we are talking about a specific guest list, just as English says the guest list.

Leaving out the article would sound unnatural in ordinary standard speech unless you were speaking in a very special style, such as notes, headlines, or highly reduced speech.

So for normal sentence building, learners should treat a vendéglista as the correct form here.

You would say:

• A vendéglista nem teljes.

Here nem means not and usually comes before the word it negates.

So:

• teljes = complete
• nem teljes = not complete

This is a very useful pattern in Hungarian:

• A szoba nagy. = The room is big.
• A szoba nem nagy. = The room is not big.
