Az ideiglenes parkolási engedély érvényes.

Az is the Hungarian definite article, equivalent to the.

Hungarian has two forms of the definite article:

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

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

• az ideiglenes... = the temporary...

This is similar to how English uses a and an, but Hungarian does it with the definite article instead.

The subject is:

• Az ideiglenes parkolási engedély = the temporary parking permit

The predicate is:

• érvényes = valid

So the structure is basically:

• [Subject] + [predicate adjective]
• The temporary parking permit + valid

In natural English, we supply is, but Hungarian does not always need an explicit verb here.

It is omitted.

In Hungarian, in the present tense, third person singular and third person plural, the verb lenni (to be) is usually left out when it links a subject to a noun or adjective.

So:

• Az engedély érvényes. = The permit is valid.
• literally: The permit valid.

But in other persons, Hungarian does use forms of to be:

• Én boldog vagyok. = I am happy.
• Te boldog vagy. = You are happy.

So this omission is normal and very common.

It is an adjective.

• érvényes = valid, in force, effective

In this sentence, it works as a predicate adjective:

• Az ideiglenes parkolási engedély érvényes.
• The temporary parking permit is valid.

So even though English uses is valid, Hungarian simply uses the adjective by itself in this kind of sentence.

Because Hungarian adjectives and many noun modifiers normally come before the noun.

Here:

• ideiglenes = temporary
• parkolási = parking
• engedély = permit

So the noun phrase is built like this:

• ideiglenes modifies the whole phrase parkolási engedély
• parkolási directly modifies engedély

That gives:

• ideiglenes parkolási engedély = temporary parking permit

This is very similar to English word order, where modifiers also usually come before the noun.

Parkolási means something like related to parking or for parking.

It comes from the verb:

• parkol = to park

From that, Hungarian can form a noun/adjectival stem referring to the activity:

• parkolás = parking
• parkolási = parking / related to parking

So:

• parkolási engedély = parking permit

This -ási / -ési pattern is very common in Hungarian for forming words connected to an action:

• fizet = to pay
• fizetés = payment / salary
• fizetési mód = method of payment

Because Hungarian adjectives do not agree with nouns the way adjectives do in many Indo-European languages.

There is:

• no masculine/feminine/neuter agreement
• no singular/plural agreement in this position
• no special adjective ending here

So:

• ideiglenes engedély = temporary permit
• ideiglenes engedélyek = temporary permits

Notice that ideiglenes stays the same.

This is much simpler than in languages where adjectives have to match the noun in gender, number, or case.

No. Hungarian does not have grammatical gender.

So engedély is not masculine, feminine, or neuter. The same is true for nouns in general.

This means:

• adjectives do not change for gender
• articles do not change for gender
• pronouns like he/she are not built into the noun system the way they are in many European languages

That is one reason Hungarian noun phrases can feel comparatively straightforward.

Because the sentence is in a basic, unmarked form.

• Az ideiglenes parkolási engedély is the subject
• érvényes is the predicate adjective

Hungarian dictionary forms are often used when a noun is the subject, and the subject does not need a special ending. You can think of this as the nominative, though Hungarian usually treats it as the base form with no ending.

So:

• engedély is just the plain noun form
• there is no accusative, dative, etc. needed here

This word order is the most neutral and natural way to say it:

• Az ideiglenes parkolási engedély érvényes.

Hungarian word order is fairly flexible, but changes often affect focus, emphasis, or topic.

For example, this sentence as given simply states a fact:

• The temporary parking permit is valid.

If you changed the order, it could sound marked, contrastive, or context-dependent. So for learners, this version is the safest neutral model.

A few useful pronunciation points:

• Hungarian stress is always on the first syllable
• written vowels with accents are pronounced clearly and distinctly

Approximate pronunciation:

• érvényes ≈ AIR-vay-nyesh
• ideiglenes ≈ EE-deh-eeg-leh-nesh
• engedély ≈ EN-gheh-day
• parkolási ≈ PAR-ko-laa-shee

A few sound notes:

• é is a long vowel, somewhat like ay in careful pronunciation
• ny is like the ny in Spanish señor or the ni in onion
• s in Hungarian sounds like English sh
• sz sounds like English s

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