Ez egy ismert régiség.

In Hungarian, the verb van (to be) is usually left out in the present tense when the subject is third person and the sentence is equational or descriptive.

So:

• Ez egy ismert régiség. = This is a well-known antique.
• literally, Hungarian says something like This a well-known antique.

This omission happens very often:

• Ő tanár. = He/She is a teacher.
• Az ház nagy. = That house is big.

But in other persons, the verb appears:

• Én tanár vagyok. = I am a teacher.
• Te tanár vagy. = You are a teacher.

So the lack of is here is completely normal Hungarian grammar.

Ez means this.

It is the near demonstrative, used for something close to the speaker, just like English this. Its counterpart is:

• ez = this
• az = that

In Ez egy ismert régiség, ez is the subject: this.

You will also often see ez in phrases like:

• ez a könyv = this book

That is slightly different from the sentence here. In your sentence, ez stands alone as this.

Egy usually means one, but it is also the indefinite article a/an.

So here:

• egy ismert régiség = a well-known antique

This is very similar to English:

• one book / a book
• Hungarian: egy könyv

Whether egy means one or just a/an depends on context and stress. In your sentence, it is simply the article a/an, not the number one.

Ismert is an adjective here, meaning known, well-known, or famous, depending on context.

So:

• ismert ember = a well-known person
• ismert hely = a known/well-known place
• ismert régiség = a well-known antique

A useful thing for English speakers: Hungarian adjectives do not change for singular/plural, gender, or case in basic noun phrases the way they do in many European languages.

So:

• ismert régiség
• ismert régiségek

The adjective stays ismert.

Régiség literally comes from the idea of oldness or something old, and it can mean:

• antique
• antiquity
• old artifact
• sometimes curio or old object

In many everyday contexts, régiség is a good translation for antique.

However, depending on context, it can sometimes sound a little broader than English antique. For example, it can refer to an old object of historical or collectible value, not just furniture-shop antiques.

So in this sentence, antique is a very natural translation.

In Hungarian, adjectives normally come before the noun, just like in English.

So:

• ismert régiség = well-known antique
• régi ház = old house
• szép könyv = beautiful book

This is one of the easier parts for English speakers, because the order is familiar.

Yes. Hungarian word order is quite flexible, and changes in word order often affect focus or emphasis rather than basic meaning.

The neutral sentence is:

• Ez egy ismert régiség.

But you could also say:

• Egy ismert régiség ez.

That version puts more emphasis on what it is. It can sound a bit like:

• This is a well-known antique
• or even It’s a well-known antique, this one

So the original order is the most straightforward, neutral choice.

A rough pronunciation guide is:

• Ez ≈ ez
• egy ≈ something like edj or ejgy
• ismert ≈ ish-mert
• régiség ≈ ray-ghee-shayg

A few useful pronunciation notes:

• s in Hungarian sounds like English sh
• sz sounds like English s
• gy is a soft consonant somewhat like the dy in British duke for some speakers, though not exactly
• é is a long vowel, somewhat like ay in say, but pure and steady

So régiség has both long é vowels, which should be held a bit longer than a short e.

Yes, very much. In Hungarian, accent marks are not optional spelling decorations; they show different vowels.

For example:

• e and é are different vowels
• i and í are different
• o / ó, ö / ő, u / ú, ü / ű are also distinct

So régiség must be written with the accents. They affect both pronunciation and correct spelling.

For learners, it is best to treat accented vowels as full separate vowels, not as minor variations.

Yes, it would be possible, but the nuance is a little different.

• ismert = known, well-known
• híres = famous

So:

• Ez egy ismert régiség. = This is a well-known antique.
• Ez egy híres régiség. = This is a famous antique.

Híres is usually stronger. Ismert can be a bit more neutral and broader.

So the original sentence suggests something recognized or known, but not necessarily extremely famous.
