Az előzetes terv kész.

In Hungarian, the verb to be is often left out in the present tense when the sentence is simply saying that something is something.

So:

• Az előzetes terv kész. = The preliminary plan is ready.

This is completely normal in Hungarian.

But the verb van can appear in other situations, for example:

• A terv kész volt. = The plan was ready.
• A terv kész lesz. = The plan will be ready.

So in the present tense, third person, Hungarian often has no visible verb where English uses is/are.

Az is the definite article, meaning the.

So:

• az = the

Hungarian has two forms of the definite article:

• a
• az

The choice depends on the sound at the beginning of the next word:

• a before most consonant sounds
• az before vowel sounds

Here the next word is előzetes, which begins with a vowel sound, so Hungarian uses az:

• az előzetes terv

Előzetes is an adjective. Here it means something like:

• preliminary
• initial
• prior
• sometimes advance

In this sentence it describes terv:

• előzetes terv = preliminary plan

It comes from előzetes as a standard adjective meaning something done beforehand or existing in advance.

In Hungarian, adjectives normally come before the noun they describe, just as they usually do in English.

So:

• előzetes terv = preliminary plan
• jó ötlet = good idea
• nagy ház = big house

That part is quite familiar for English speakers.

Terv means plan.

In this sentence it is in its basic dictionary form, because it is the subject of the sentence:

• terv = plan

Hungarian nouns do not have grammatical gender, so terv is not masculine, feminine, or neuter. It is simply a noun.

Also, unlike in English, Hungarian does not use a separate word like is here, so terv stays unchanged.

Here kész means ready or finished, depending on context.

In this sentence:

• A/az ... kész. = The ... is ready.

So:

• Az előzetes terv kész. = The preliminary plan is ready.

A useful thing to know is that kész is often used predicatively, meaning it appears after the noun and describes its state:

• A vacsora kész. = Dinner is ready.
• A munka kész. = The work is finished.

Hungarian adjectives do not agree with nouns the way they do in many European languages.

That means the adjective usually stays the same regardless of:

• gender
• number
• case

So:

• kész terv would not be a normal phrase for ready plan, but in predicate position:
• A terv kész. = The plan is ready.
• A tervek készek. = The plans are ready.

One important detail: when the adjective itself is effectively standing as the predicate for a plural subject, it can take the plural marker:

• A terv kész.
• A tervek készek.

So adjectives do not behave like English exactly, but they also do not have full agreement like in some other languages.

Yes, Hungarian word order is flexible, but changes usually affect focus, emphasis, or topic.

The neutral sentence is:

• Az előzetes terv kész.

This simply states the fact.

Other word orders may be possible in context, but they would usually sound marked or emphasize something:

• Kész az előzetes terv. = roughly The preliminary plan is ready / Ready is the preliminary plan, with more focus on ready

A learner should treat Az előzetes terv kész. as the normal, straightforward version.

A rough pronunciation guide is:

• Az ≈ ahz
• előzetes ≈ eh-luh-zeh-tesh
• terv ≈ tehrv
• kész ≈ kayss

A few useful pronunciation notes:

• é is a long vowel, roughly like the vowel in say, but pure and steady
• ő is a long front rounded vowel, which English does not really have
• sz is pronounced like English s
• s by itself in Hungarian is pronounced like English sh
• z is like English z

So kész has sz, which sounds like s, not z.

Yes. It is a fully complete and natural Hungarian sentence.

Its structure is:

• Az előzetes terv = the subject, the preliminary plan
• kész = the predicate adjective, ready

Even though there is no visible word for is, Hungarian grammar still treats this as a complete sentence.

Possibly, depending on context.

• előzetes terv can mean preliminary plan, initial plan, or sometimes something close to draft plan
• kész can mean ready or finished

So the exact English translation depends on the situation.

For example:

• if someone has completed preparing the plan, The preliminary plan is ready is natural
• if the emphasis is that work on it has been completed, The draft plan is finished may also fit

So the Hungarian sentence is short, but it can map to slightly different English versions depending on context.
