A munkavállaló felelős a nehéz feladatért.

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

So:

• A munkavállaló felelős. = The employee is responsible.
• literally, it looks more like The employee responsible.

This is completely normal Hungarian.

But van can appear in other situations, for example:

• past: A munkavállaló felelős volt... = The employee was responsible...
• future: A munkavállaló felelős lesz... = The employee will be responsible...

Munkavállaló means employee.

It is built from smaller parts:

• munka = work
• vállal = to undertake, to accept
• -ó = a participle ending that can make a person-word

So the word is roughly someone who undertakes work, which developed into employee.

It is a very normal word, especially in formal, legal, HR, or workplace contexts. In everyday speech, you may also see:

• dolgozó = worker, employee
• alkalmazott = employee

Yes. In this sentence, both instances of a mean the.

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

So here:

• a munkavállaló = the employee
• a nehéz feladatért = for the difficult task

Both use a because:

• munkavállaló starts with m
• nehéz starts with n

If the next word started with a vowel, you would use az, for example:

• az alkalmazott = the employee

No. Felelős is an adjective meaning responsible.

In this sentence, it works as the predicate adjective:

• A munkavállaló felelős... = The employee is responsible...

There is a related verb, felel, but it is not the same thing. Hungarian often uses an adjective where English also uses an adjective, and in the present-tense third person it does not need an explicit is.

So this sentence is not built around a main verb like is responsible in English; instead, it is built around the adjective felelős.

The ending -ért is a suffix meaning roughly for.

So:

• feladat = task
• feladatért = for the task

Hungarian often uses suffixes where English uses prepositions. Instead of putting a separate word before the noun, Hungarian very often attaches the meaning to the noun itself.

With felelős, this is the normal pattern:

• felelős valamiért = responsible for something

So:

• a nehéz feladatért = for the difficult task

Not exactly. -ért often corresponds to English for, but the exact meaning depends on the context.

For example, it can be used for:

• responsibility: felelős valamiért = responsible for something
• thanks: Köszönöm a segítséget. / Köszönet a segítségért. = thanks for the help
• exchange: tíz euróért = for ten euros
• purpose/benefit in some contexts: érted = for you, on your behalf

In your sentence, the meaning is specifically the one required by felelős:

• felelős a feladatért = responsible for the task

So the important thing for learners is to remember the pattern felelős + -ért.

Because in Hungarian, when an adjective comes before a noun, the noun usually carries the case ending, not the adjective.

So:

• nehéz feladat = difficult task
• nehéz feladatért = for a/the difficult task

The adjective nehéz stays unchanged.

This is very common in Hungarian. The same thing happens with plural too:

• nehéz feladatok = difficult tasks
• nehéz feladatokért = for difficult tasks

The main noun is the word that gets the grammatical marking.

Because the article belongs to the whole noun phrase, and nehéz feladatért is one noun phrase.

Hungarian places the article at the front of the whole phrase:

• a nehéz feladatért

That corresponds to English:

• for the difficult task

So the structure is not:

• for + the + task

  but more like:

• the difficult task + for-suffix

Hungarian builds the phrase differently from English, but the meaning is the same.

Yes, this is a normal, neutral word order:

• A munkavállaló felelős a nehéz feladatért.

Very roughly, it is:

• subject: A munkavállaló
• predicate: felelős
• complement: a nehéz feladatért

But Hungarian word order is more flexible than English word order. It often changes to show emphasis or focus.

For example:

• A nehéz feladatért a munkavállaló felelős.

This puts more emphasis on the employee as the one responsible for the difficult task.

So yes, the order can change, but the original sentence is a good neutral version.

Because a is the definite article, so the sentence is talking about a specific difficult task:

• a nehéz feladatért = for the difficult task

If you wanted for a difficult task, you would say:

• egy nehéz feladatért

So the difference is:

• a = the
• egy = a/an

Hungarian uses this distinction much like English does, although articles are sometimes used a little differently depending on context.

Yes, they matter a lot. In Hungarian, accent marks are not optional spelling marks; they show real vowel differences.

For example:

• a and á are different vowels
• o and ó are different
• ö and ő are different

So you should learn the words with the correct accents:

• munkavállaló
• felelős
• nehéz

Also, Hungarian stress normally falls on the first syllable of the word, so the stress pattern is much more regular than in English.
