A parkolási engedély díjmentes.

In Hungarian, the verb van (to be) is usually left out in the present tense, third person when the sentence links a subject to a noun or adjective.

So:

• A parkolási engedély díjmentes. = The parking permit is free of charge.

But in the past or future, or with I/you/we, Hungarian normally uses the verb:

• A parkolási engedély díjmentes volt. = The parking permit was free of charge.
• Én fáradt vagyok. = I am tired.

So the missing is is completely normal here.

Parkolási means something like related to parking or parking-.

It comes from:

• parkol = to park
• parkolás = parking (the act/process of parking)
• parkolási = parking / related to parking

The -i ending often turns a noun into an adjective meaning connected with or belonging to something.

So:

• parkolás = parking
• parkolási engedély = parking permit

This is very common in Hungarian:

• tanulás = studying
• tanulási lehetőség = study opportunity / opportunity for learning

Because Hungarian usually prefers an adjectival form here.

• parkolás is a noun: parking
• parkolási is an adjective-like form: parking / related to parking

So parkolási engedély is the natural way to say parking permit.

Using parkolás engedély would sound wrong in standard Hungarian. The relationship between the two words needs to be marked, and -i does that here.

Engedély means permit, license, or authorization, depending on context.

In this sentence, it means permit:

• parkolási engedély = parking permit

You may also see it in other combinations:

• építési engedély = building permit
• munkavállalási engedély = work permit

So engedély is a useful formal word for something officially allowed.

Díjmentes literally means without fee or free of charge.

It is made of:

• díj = fee, charge
• mentes = free from, exempt from

So:

• díjmentes = exempt from payment / no fee required

This word is a bit more formal or official than everyday ingyenes.

For example:

• A szolgáltatás ingyenes. = The service is free.
• A parkolási engedély díjmentes. = The parking permit is free of charge.

In official notices, díjmentes is very common.

Yes, often you could, but the tone is a little different.

• ingyenes = free, gratis
• díjmentes = free of charge, fee-exempt

Ingyenes is more everyday and general. Díjmentes sounds more official, administrative, or bureaucratic.

So:

• A parkolási engedély ingyenes.
  This is understandable and natural.
• A parkolási engedély díjmentes.
  This sounds more like something you would read on a sign, form, or official notice.

Hungarian has two forms of the definite article:

• a
• az

Which one is used depends on the sound that follows:

• a before a consonant
• az before a vowel

Here the next word is parkolási, which starts with p, a consonant, so we use:

• a parkolási engedély

Compare:

• az engedély = the permit
• a parkolási engedély = the parking permit

Hungarian often uses the definite article where English might leave it out, especially in full sentence style.

So:

• A parkolási engedély díjmentes.

is a complete, natural Hungarian sentence meaning The parking permit is free of charge.

On signs and notices, Hungarian can also sometimes drop articles in shorter label-style wording, but this full version with a is perfectly normal and probably the most straightforward standard sentence.

The subject is:

• A parkolási engedély = the parking permit

The predicate adjective (the word describing it) is:

• díjmentes = free of charge

So the structure is:

• [subject] + [adjective]

Even though English uses is, Hungarian simply puts the subject and adjective next to each other in this kind of present-tense sentence.

Yes. Hungarian word order is flexible, and changing it often changes the focus or emphasis.

Neutral statement:

• A parkolási engedély díjmentes.
  = The parking permit is free of charge.

With emphasis on free of charge:

• Díjmentes a parkolási engedély.

This version draws more attention to the fact that it is free.

So both are possible, but the original sentence is a neutral, standard way to say it.

Yes, it sounds fairly formal or administrative, mainly because of díjmentes and engedély.

It sounds like something you might see:

• on a notice
• on a municipal website
• on an application form
• in official information

A more casual everyday sentence might use ingyenes instead:

• A parkolási engedély ingyenes.

But the original sentence is very natural in official contexts.

A rough pronunciation guide:

• parkolási ≈ PAR-ko-laa-shee
• díjmentes ≈ DEEY-men-tesh

A few helpful points:

• á is a long a sound
• í is a long ee sound
• s in Hungarian sounds like English sh
• j usually sounds like English y

So:

• parkolási: the final -si sounds like shee
• díj sounds roughly like deey

Also, Hungarian stress is almost always on the first syllable:

• PARkolási
• DÍJmentes

Yes, díjmentes is an adjective.

Here it stays in its basic form because it is describing a singular subject in a simple present-tense sentence.

Hungarian adjectives do not change the way adjectives do in many Indo-European languages. They do not have different forms for masculine/feminine, and they usually do not agree in number in this position.

So:

• A parkolási engedély díjmentes. = The parking permit is free of charge.
• A parkolási engedélyek díjmentesek. = The parking permits are free of charge.

Notice that in plural predicate position, the adjective often takes a plural ending too:

• díjmentes → díjmentesek

So the form can change for plural predicative use, but there is no gender agreement.

It is a very typical informational statement.

Hungarian often uses short, direct sentences like this in public or official language:

• A belépés ingyenes. = Entry is free.
• A regisztráció kötelező. = Registration is mandatory.
• A parkolási engedély díjmentes. = The parking permit is free of charge.

So this sentence is a good example of a practical, real-world Hungarian structure.
