A hirdetésben az ingatlan drága.

Because -ban / -ben is the Hungarian suffix meaning in or inside.

• hirdetés = advertisement, ad
• hirdetésben = in the advertisement

Hungarian often uses suffixes where English uses separate words like in, on, to, from, etc.

Here the suffix is -ben, not -ban, because of vowel harmony:

• words with front vowels usually take -ben
• words with back vowels usually take -ban

Since hirdetés contains front vowels, -ben is used.

The first A is the definite article, meaning the.

So:

• a hirdetésben = in the advertisement

Hungarian has two forms of the definite article:

• a
• az

They both mean the. Which one is used depends on the sound that follows.

Hungarian chooses the form of the based on the next word:

• a before a word starting with a consonant
• az before a word starting with a vowel

So:

• a hirdetésben because hirdetésben starts with h
• az ingatlan because ingatlan starts with i

This is similar to English a vs an, but in Hungarian it applies to the definite article the, not the indefinite article.

In Hungarian, the verb to be is often omitted in the present tense, third person when connecting a subject to a noun or adjective.

So:

• az ingatlan drága literally looks like the property expensive
• but it means the property is expensive

This omission is completely normal.

Compare:

• Én fáradt vagyok. = I am tired.
• Te fáradt vagy. = You are tired.
• Ő fáradt. = He/She is tired.

In the third person singular, Hungarian usually leaves out van in this type of sentence.

Az ingatlan is the subject of the sentence.

• ingatlan = property, real estate
• az ingatlan = the property

The sentence says something about that property: namely, that it is drága.

So the structure is basically:

• A hirdetésben = in the advertisement
• az ingatlan = the property
• drága = expensive

Because in this sentence drága is not directly modifying the noun like an expensive property. Instead, it is the predicate adjective:

• az ingatlan drága = the property is expensive

Compare these two:

• drága ingatlan = expensive property
• az ingatlan drága = the property is expensive

So position matters.

Not completely. Hungarian word order is fairly flexible and often reflects focus or emphasis.

This version is natural if you want to set the scene first:

• A hirdetésben az ingatlan drága.
• In the advertisement, the property is expensive.

You could also say:

• Az ingatlan drága a hirdetésben.

That can be grammatical too, but it may sound different in emphasis, and the original sentence is usually the more neutral way to present the location/context first.

So the word order is not random, but it is more flexible than in English.

Ingatlan is a broad word meaning real estate or property.

Depending on context, it can refer to:

• a house
• an apartment
• land
• property in general

So in a sentence like this, az ingatlan is best understood as the property.

In theory, drága can mean both expensive and dear/beloved, depending on context.

But here, with ingatlan meaning property, the natural meaning is clearly expensive.

Examples:

• drága könyv = an expensive book
• drága barátom = my dear friend

So context tells you which meaning is intended.

Because Hungarian is an agglutinative language: it often adds endings directly to nouns instead of using separate prepositions.

English:

• in the advertisement

Hungarian:

• a hirdetésben

The in idea is built into the noun through the suffix -ben.

This is one of the big structural differences between English and Hungarian.

It is talking about the advertisement as the context of the statement, not the physical location of the property.

So A hirdetésben az ingatlan drága means something like:

• In the advertisement, the property is expensive
• According to the advertisement, the property is expensive

It does not mean the property is physically inside the advertisement, of course. Hungarian often uses location forms like this for textual or informational context too.
