A megye nagy.

In Hungarian, a is the definite article meaning the before most consonants.

So:

• a megye = the county

Hungarian has two forms of the:

• a before most consonants
• az before vowels

Since megye starts with m, it takes a, not az.

Megye means county. It is an administrative region.

In modern Hungarian, it usually refers to a county-level division of the country. Depending on context, you may also see it in official names of places.

Because in this sentence, nagy is not directly modifying the noun inside a noun phrase. It is the predicate adjective.

Compare:

• a nagy megye = the big county
  Here, nagy comes before the noun because it directly describes megye inside the noun phrase.

• a megye nagy = the county is big
  Here, nagy comes after the noun because it is the main description in the sentence.

So Hungarian often works like this:

• adjective before noun = big county
• adjective after noun = the county is big

In Hungarian, the verb to be is often omitted in the third person singular and plural in the present tense.

So:

• A megye nagy. literally looks like The county big.
• but it means The county is big.

This is completely normal Hungarian.

Compare:

• én nagy vagyok = I am big
• te nagy vagy = you are big
• a megye nagy = the county is big
  no separate word for is

No. Those are not correct.

In a simple present-tense sentence like this, Hungarian does not use van for is in the third person when describing something with a noun or adjective.

Correct:

• A megye nagy. = The county is big.

Incorrect:

• A megye nagy van.
• A megye van nagy.

You do use van in other situations, especially for existence or location:

• Itt van. = It is here.
• A megyehatár itt van. = The county border is here.

A rough guide is:

• megye ≈ MEH-dyeh, but with a softer middle sound than English dy

More specifically:

• me sounds like meh
• gy is a special Hungarian consonant, somewhat like the d in British-style during for some speakers, or a softened dy
• final e is pronounced, not silent

So megye is two syllables: me-gye.

gy is a single Hungarian consonant, not a g plus y.

It is pronounced with the tongue close to the hard palate, and English does not have an exact equivalent. A useful approximation is a soft dy sound.

Examples:

• gyerek = child
• megye = county

So when reading megye, do not pronounce it like meg-yay or meg-yee. Think more like meh-dyeh, but softer and smoother.

No. Hungarian does not have grammatical gender like masculine, feminine, and neuter.

So nagy stays the same regardless of what it describes.

Examples:

• a megye nagy = the county is big
• a ház nagy = the house is big
• a város nagy = the city is big

The adjective does not change for gender.

Not in this kind of sentence.

Hungarian adjectives usually do not agree in number when used predicatively.

So:

• A megye nagy. = The county is big.
• A megyék nagyok. = The counties are big.

Notice something important:

• singular predicate adjective: nagy
• plural predicate adjective: nagyok

So in predicate position, Hungarian often does mark plural. But it still does not behave like full adjective agreement in the way some Indo-European languages do.

Also compare attributive use:

• nagy megye = big county
• nagy megyék = big counties

Here the adjective stays nagy before the noun.

The plural is megyék.

So:

• megye = county
• megyék = counties

With the article:

• a megye = the county
• a megyék = the counties

And a full sentence:

• A megyék nagyok. = The counties are big.

Yes, but word order in Hungarian often affects focus and emphasis.

The neutral sentence is:

• A megye nagy. = The county is big.

You might also see:

• Nagy a megye.

This still means roughly The county is big, but it gives more emphasis to big, almost like:

• The county is big
• or Big is the county, in a marked or contrastive sense

So the basic learner-friendly version is A megye nagy., but Hungarian word order is more flexible than English.

Because az is used before vowel sounds, while megye begins with a consonant.

So:

• a megye ✅
• az megye ❌

Examples:

• a ház = the house
• az iskola = the school

Yes. It is a complete, grammatical, natural Hungarian sentence.

It has:

• A megye = the subject, the county
• nagy = the predicate adjective, big

And in the present tense, third person, Hungarian does not need to say is explicitly here.

So this is a normal full sentence, not a fragment.
