A futár köteles kézbesíteni a küldeményt.

Here A means the, not a.

In Hungarian, the definite article has two forms:

• a before a consonant
• az before a vowel

So:

• a futár = the courier
• az autó = the car

Hungarian does not distinguish a and an the way English does. Instead, it distinguishes a and az based on the following sound.

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

So:

• A futár köteles. = The courier is obliged.
• not normally A futár van köteles.

In your sentence, köteles is the predicate adjective, so no van appears:

• A futár köteles kézbesíteni a küldeményt.

But in other persons or tenses, a form of van does appear:

• Köteles vagyok. = I am obliged.
• Köteles volt. = He/she was obliged.

This is a very common feature of Hungarian.

Köteles means obliged, required, or duty-bound. It is stronger and more formal than simply saying someone has to do something.

So:

• A futár köteles kézbesíteni a küldeményt.
  = The courier is obliged/required to deliver the consignment.

This wording often sounds legal, official, or rule-based.

A useful pattern is:

• valaki köteles + infinitive
• someone is obliged to + verb

Example:

• A diák köteles megjelenni. = The student is required to appear.

The ending -ni makes the verb an infinitive, like English to deliver.

So:

• kézbesít = delivers
• kézbesíteni = to deliver

After köteles, Hungarian normally uses the infinitive:

• köteles kézbesíteni = is obliged to deliver

This is similar to English obliged to deliver.

Kézbesíteni means to deliver, especially in the sense of officially bringing mail, parcels, documents, or notices to the recipient.

It is more specific than szállítani:

• kézbesíteni = to deliver to the addressee/recipient
• szállítani = to transport, to ship, to carry

So in a postal/courier context, kézbesíteni is the natural choice.

Because it is the direct object of the verb, so it takes the accusative ending -t.

• küldemény = consignment, item sent, postal item
• küldeményt = the consignment as the object

In this sentence, the courier is delivering something, and that thing is the object:

• kézbesíteni a küldeményt = to deliver the consignment

Hungarian often adds -t to mark the object, although the exact shape of the ending can vary a little depending on the word.

Because the sentence refers to a specific consignment, so Hungarian uses the definite article:

• a küldeményt = the consignment

Without the article, the meaning would be less specific and would sound different in style or meaning.

So here:

• A futár köteles kézbesíteni a küldeményt.
• The courier is obliged to deliver the consignment.

Both the subject and the object are definite here:

• A futár = the courier
• a küldeményt = the consignment

No. Hungarian has no grammatical gender.

So futár can mean:

• male courier
• female courier

The word itself does not tell you the person’s sex. If needed, Hungarian adds extra words to specify that, but normally it just says futár.

This is very different from languages that have masculine/feminine noun forms.

Yes, Hungarian word order is flexible, but this sentence has a very natural, neutral order:

• A futár = topic / what we are talking about
• köteles = main predication
• kézbesíteni a küldeményt = what the courier is obliged to do

So the sentence feels like:

• As for the courier, he/she is obliged to deliver the consignment.

Other word orders are possible, but they change the emphasis. For example, moving a küldeményt earlier could emphasize the consignment.

So this version is a straightforward, neutral statement.

Both can express obligation, but they work differently.

köteles

This means is obliged / is required and is often formal or legal.

• A futár köteles kézbesíteni a küldeményt.
• The courier is obliged to deliver the consignment.

kell

This means must / have to / it is necessary and is more general.

• A futárnak kézbesítenie kell a küldeményt.
• The courier has to deliver the consignment.

So köteles sounds more like an official duty or rule, while kell is the more general way to say something is necessary.

Not exactly.

• csomag = package, parcel
• küldemény = shipment, consignment, postal item, something that has been sent

Küldemény is a broader and often more official word. It can refer to various kinds of sent items, not just a parcel.

So in official or postal language, küldemény is very common.

A rough pronunciation guide is:

• A = short aw
• futár = foo-taar
• köteles = something like kuh-teh-lesh
• kézbesíteni = kayz-beh-see-tee-neh
• a küldeményt = aw kuel-deh-maynyt

A few useful sound notes:

• á is longer than a
• é is like a long ay
• ö and ü are front rounded vowels, which English does not really have
• s is pronounced like English sh
• sz is pronounced like English s

So kézbesíteni and küldeményt may feel a bit unfamiliar at first because of the vowels and consonant combinations.

Normally, A futár means the courier, not a courier.

If Hungarian wanted the indefinite meaning a courier, it would usually say:

• Egy futár köteles kézbesíteni a küldeményt.

So your sentence most naturally means:

• The courier is obliged to deliver the consignment.

That said, in some contexts Hungarian can sound more generic than English, but grammatically a futár is definite.
