Ez műszaki probléma.

In Hungarian, the verb van (is) is usually left out in the present tense, third person when the predicate is a noun or an adjective.

So:

• Ez műszaki probléma. = This is a technical problem.
• literally: This technical problem.

This is completely normal Hungarian.

But in other persons or tenses, the verb appears:

• Én fáradt vagyok. = I am tired.
• Ez probléma volt. = This was a problem.
• Ez probléma lesz. = This will be a problem.

So the missing is is not an omission in the casual sense; it is the standard grammar.

Ez means this.

Here it is being used as a pronoun, standing on its own:

• Ez műszaki probléma. = This is a technical problem.

Compare that with ez a ..., which is used before a noun:

• ez a probléma = this problem

So:

• Ez műszaki probléma. = This is a technical problem.
• Ez a műszaki probléma. = This technical problem / This is the technical problem, depending on context.

That small a makes a big difference.

Hungarian often leaves out egy in sentences like this, especially when something is being classified or identified by type.

So both of these are possible:

• Ez műszaki probléma.
• Ez egy műszaki probléma.

The version without egy can sound a little more like classification:

• This counts as a technical problem.
• This is of the technical-problem kind.

The version with egy is also very natural and may feel a bit more explicit to English speakers:

• Ez egy műszaki probléma. = This is a technical problem.

So if you are learning, it is useful to know that both can be correct, but Hungarian often omits egy where English requires a/an.

Because in Hungarian, attributive adjectives normally come before the noun they describe.

So:

• műszaki probléma = technical problem
• nagy ház = big house
• jó ötlet = good idea

This is the normal order. For learners, the safest pattern is:

adjective + noun

No, not here.

Hungarian adjectives do not change for gender, because Hungarian has no grammatical gender. They also do not agree with the noun the way adjectives do in many Indo-European languages.

So you get:

• műszaki probléma = technical problem
• műszaki problémák = technical problems
• műszaki problémát = a technical problem (object form)

Notice that the adjective műszaki stays the same, while the noun changes.

That is very typical in Hungarian.

Műszaki usually means something like:

• technical
• engineering-related
• mechanical
• related to equipment or technology

The exact English translation depends on context.

So műszaki probléma can mean:

• technical problem
• technical issue
• engineering problem
• mechanical problem

In everyday use, it often refers to a problem involving machinery, equipment, systems, or technical functioning.

Here probléma is in the nominative form, which is the basic dictionary form.

That is because it is not a direct object. It is the predicate noun in a sentence meaning This is a technical problem.

So:

• Ez műszaki probléma. = predicate noun, no accusative ending

But if it were a direct object, you would use the accusative:

• Látok egy műszaki problémát. = I see a technical problem.

There, probléma becomes problémát.

A rough guide:

• Ez ≈ ez in bed, but with a z sound at the end
• műszaki ≈ myoo-sah-kee, but the first vowel is special
• probléma ≈ PRO-blay-maw

A few important pronunciation notes:

• sz in Hungarian is pronounced like English s
• Hungarian stress is normally on the first syllable
• ű is a long vowel that English does not really have

For ű, try saying ee while rounding your lips as if for oo.

So műszaki starts with a sound somewhat like a long rounded ee.

Yes, Hungarian word order is flexible, but different orders create different emphasis.

The neutral, straightforward version is:

• Ez műszaki probléma.

You might also hear:

• Műszaki probléma ez.

That sounds more marked, with stronger focus on műszaki probléma, something like:

• This is a technical problem.

For a learner, the safest default is the original order:

• Ez műszaki probléma.

The plural version is:

• Ezek műszaki problémák. = These are technical problems.

Here:

• ez becomes ezek = these
• probléma becomes problémák = problems

If you want these technical problems as a noun phrase, you would say:

• ezek a műszaki problémák

So compare:

• Ezek műszaki problémák. = These are technical problems.
• Ezek a műszaki problémák. = These technical problems / These are the technical problems, depending on context.

No, they are not the same.

• Ez műszaki probléma. = This is a technical problem.
• Ez a műszaki probléma. can mean this technical problem as a noun phrase, or in context this is the technical problem

The form ez a ... is used directly before a noun:

• ez a könyv = this book
• ez a probléma = this problem

So if you want the sentence meaning This is a technical problem, the original version is correct. If you insert a, you change the structure.
