Az internetkapcsolat gyors.

Hungarian has two forms of the definite article:

• a
• az

The choice depends on the sound that follows.

• Use a before a word beginning with a consonant sound
• Use az before a word beginning with a vowel sound

Since internetkapcsolat begins with i, Hungarian uses az:

• az internetkapcsolat

This is similar to the difference between a and an in English, although Hungarian uses this rule only for the definite article.

Internetkapcsolat is a compound noun:

• internet = internet
• kapcsolat = connection, contact, link

So internetkapcsolat literally means internet connection.

Hungarian very often forms new nouns by combining words into one single long word. This is completely normal and very common.

In this sentence, gyors is not directly describing the noun inside a noun phrase like the fast internet connection. Instead, it is part of the sentence predicate:

• Az internetkapcsolat gyors.
• The internet connection is fast.

So the structure is:

• Az internetkapcsolat = the internet connection
• gyors = fast

This is like saying X is Y.

If you wanted to say the fast internet connection, with the adjective directly attached to the noun, Hungarian would normally put the adjective before the noun:

• a gyors internetkapcsolat = the fast internet connection

So:

• Az internetkapcsolat gyors. = The internet connection is fast.
• A gyors internetkapcsolat = the fast internet connection.

Hungarian often leaves out van (is) in the third person singular present tense when the sentence simply identifies or describes something.

So Hungarian says:

• Az internetkapcsolat gyors.

Literally, this looks like:

• The internet connection fast.

But it means:

• The internet connection is fast.

This omission is normal in Hungarian.

Compare:

• Én gyors vagyok. = I am fast.
• Te gyors vagy. = You are fast.
• Az internetkapcsolat gyors. = The internet connection is fast.

In the third person singular present, the copula is usually omitted in sentences like this.

Yes, gyors is an adjective meaning fast or quick.

In this sentence, it does not change form. Hungarian adjectives do not agree with the noun in gender, and Hungarian has no grammatical gender like masculine/feminine/neuter.

So gyors stays the same:

• gyors internetkapcsolat = fast internet connection
• Az internetkapcsolat gyors. = The internet connection is fast.

Hungarian adjectives are often quite stable in form compared with languages that have gender or extensive adjective agreement.

No. In this sentence, internetkapcsolat is in the basic dictionary form with the definite article:

• az internetkapcsolat

There is no visible case ending because it is the subject of the sentence.

Hungarian uses many case endings, but here none is needed.

In many Hungarian compounds, the parts are simply placed together without major changes:

• internet
  • kapcsolat → internetkapcsolat

This is very typical. Hungarian likes compact compound nouns, often where English would prefer two separate words.

So although English says internet connection, Hungarian commonly writes it as one word: internetkapcsolat.

A simple pronunciation guide is:

• Az ≈ awz
• internetkapcsolat ≈ IN-tehr-neht-kap-cho-lat
• gyors ≈ roughly dyorsh

A few useful pronunciation notes:

• Hungarian stress is usually on the first syllable of each word.
• gy is a special Hungarian sound, somewhat like a soft d+y sound.
• cs is pronounced like ch in church.
• s by itself is pronounced like English sh.
• sz would be English s, but it does not appear here.

So the main stresses are:

• AZ
• INternetkapcsolat
• GYORS

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

The neutral sentence is:

• Az internetkapcsolat gyors.

This simply states a fact: The internet connection is fast.

You might also see other orders in special contexts, but for a beginner, this neutral order is the safest and most useful one to learn first.

It can mean both fast and quick, depending on context.

Examples:

• gyors autó = fast car
• gyors válasz = quick answer
• gyors internetkapcsolat = fast internet connection

So in your sentence, gyors naturally means fast.

Yes, but it means something slightly different:

• Ez az internetkapcsolat gyors. = This internet connection is fast.

Here, ez means this.

That sentence is more specific and points to a particular connection. The original sentence:

• Az internetkapcsolat gyors.

is more simply The internet connection is fast.

Not always. The article depends on whether the noun is definite or indefinite, just as in English.

Here:

• Az internetkapcsolat gyors. = The internet connection is fast.

If you wanted an internet connection is fast or a fast internet connection, the structure would be different depending on the exact meaning.

So the article az is here because the noun is being treated as definite: the internet connection.
