A műszaki vizsga holnap lesz a vizsgaállomáson.

In everyday Hungarian, műszaki vizsga usually means a vehicle’s technical inspection or roadworthiness test, not a school-style exam.

Literally:

• műszaki = technical
• vizsga = exam / test / inspection

So the phrase is a fixed everyday expression for the inspection a car must pass.

A is the Hungarian definite article, meaning the.

So:

• A műszaki vizsga = The technical inspection
• a vizsgaállomáson = at the inspection station

Hungarian uses the definite article very regularly before specific nouns, including places. English does this too here: the inspection, the inspection station.

They both mean the.

The choice depends on the next sound:

• a before a consonant sound
• az before a vowel sound

Examples:

• a műszaki vizsga
• a vizsgaállomás
• az autó
• az állomás

Since both műszaki and vizsgaállomáson begin with consonant sounds, the form is a.

Here holnap is an adverb meaning tomorrow.

Time adverbs like this usually appear without an article:

• ma = today
• holnap = tomorrow
• tegnap = yesterday

So holnap simply tells you when something happens. It does not need a case ending in this sentence.

Lesz is the future form of van (to be), so here it means will be or will take place.

That is why:

• A műszaki vizsga holnap lesz... = The inspection will be tomorrow...

However, Hungarian often uses the present tense for scheduled future events if the time is already clear. So in everyday speech, A műszaki vizsga holnap van a vizsgaállomáson can also sound natural.

Very roughly:

• lesz = explicitly future
• van
  • holnap = also possible, often more conversational

The ending -on is a location suffix. Here it means on / at.

So:

• vizsgaállomás = inspection station
• vizsgaállomáson = at the inspection station

This suffix belongs to the set:

• -on
• -en
• -ön
• -n

Which one you use depends on the word.

Important: in English, on sounds very physical, but in Hungarian this ending is often just the normal way to say at certain places.

Because Hungarian place expressions are often idiomatic: different nouns prefer different location endings.

For some places, Hungarian uses -ban/-ben (in), but for others it naturally uses -on/-en/-ön/-n.

With állomás and compounds built on it, -on is normal:

• az állomáson = at the station
• a vizsgaállomáson = at the inspection station

So this is something you mostly learn as part of the noun’s usual pattern.

Because Hungarian adjectives do not agree with the noun the way they do in many Indo-European languages.

Before a noun, the adjective usually stays unchanged:

• műszaki vizsga
• műszaki vizsgán
• műszaki vizsgák

Notice that the noun changes, but műszaki stays the same.

This is very different from languages where adjectives change for gender, number, or case.

Yes. Hungarian forms compounds very freely, and this is one of them.

It breaks down like this:

• vizsga = exam / inspection
• állomás = station
• vizsgaállomás = inspection station
• vizsgaállomáson = at the inspection station

So first you get the compound noun, and then you add the case ending.

Yes, Hungarian word order is flexible. It depends a lot on what is already known and what is being highlighted.

In this sentence:

• A műszaki vizsga is the topic: what we are talking about
• holnap comes before the verb and is relatively prominent
• a vizsgaállomáson comes later as location information

Other orders are possible, for example:

• Holnap lesz a műszaki vizsga a vizsgaállomáson.
• A műszaki vizsga a vizsgaállomáson lesz holnap.

These are not identical in emphasis. Hungarian often uses word order to show what is most important or contrastive.

A few useful pronunciation points:

• ű in műszaki is a long front rounded vowel, similar to a long German ü
• sz is pronounced like English s
• s by itself is pronounced like English sh
• zs is pronounced like the sound in measure

So:

• műszaki has sz = s
• vizsga contains zs, so it sounds roughly like vizh-ga

Also, Hungarian stress is very regular: it normally falls on the first syllable of each word.

Both ideas fit.

In Hungarian, lesz often literally means will be, but with events it can naturally be understood as will happen or will take place.

So in this sentence, lesz does not only describe location. It can also suggest that the inspection is an event scheduled for tomorrow at that place.
