Kedvező döntést várunk.

Because the verb already shows the subject.

várunk = we wait / we are waiting / we expect / we are awaiting

The ending -unk tells you the subject is we. Hungarian often leaves subject pronouns out unless they are needed for emphasis or contrast.

So:

• Várunk. = We are waiting / expecting.
• Mi várunk. = We are waiting. (with extra emphasis on we)

It marks the direct object. This is the accusative case in Hungarian.

• döntés = decision
• döntést = decision as the thing being awaited/expected

So in Kedvező döntést várunk, the thing being awaited is a favorable decision.

A useful comparison:

• döntés = decision
• döntést = a decision / decision (as object)

Hungarian marks the object directly on the noun, instead of relying only on word order.

This is a very common Hungarian question, because Hungarian has two verb conjugations here: indefinite and definite.

In this sentence, the object is indefinite / non-specific:

• kedvező döntést = a favorable decision / favorable decision

So the verb uses the indefinite conjugation:

• várunk = we expect / await

If the object were definite, you would usually use várjuk instead:

• A döntést várjuk. = We are awaiting the decision.
• A kedvező döntést várjuk. = We are awaiting the favorable decision.

So the difference is not about tense, but about whether the object is definite or indefinite.

Hungarian often leaves out the article when the object is indefinite and not specially emphasized.

So:

• Kedvező döntést várunk. = We are awaiting a favorable decision.

This is perfectly natural.

You could also say:

• Egy kedvező döntést várunk.

But egy adds more of the feeling of one / a certain favorable decision. In many contexts, it is less neutral than leaving the article out.

So the version without egy is often the most natural choice.

Because Hungarian vár takes a direct object.

In English, you often say:

• wait for a decision

But in Hungarian, you simply say:

• döntést vár

Literally, Hungarian treats decision as the direct object of wait/expect/await.

So:

• döntést várunk = we await a decision
• not something like várunk egy döntésre in this meaning

That is why the noun gets the accusative -t.

Formally, it is present tense, but Hungarian often uses the present tense for a situation with future meaning, especially when the context makes it clear.

So Kedvező döntést várunk can naturally mean something like:

• We are awaiting a favorable decision.
• We expect a favorable decision.

It does not need a special future form to sound natural.

This is very common in Hungarian. The present tense often covers both present and near-future meanings.

No. In Hungarian, an adjective before a noun usually does not agree with the noun in case or number.

So:

• kedvező döntés = favorable decision
• kedvező döntést = favorable decision (as object)

Only the noun gets the accusative ending here:

• kedvező stays the same
• döntés becomes döntést

This is normal in Hungarian attributive adjective + noun combinations.

It is an adjective modifying döntést.

Hungarian adjectives usually come before the noun they describe:

• kedvező döntés = favorable decision
• jó eredmény = good result
• fontos kérdés = important question

So kedvező simply describes what kind of decision is being awaited.

Yes, Hungarian word order is flexible, but changing it usually changes the emphasis rather than the basic meaning.

Kedvező döntést várunk is natural and highlights the thing being awaited: a favorable decision.

If you move things around, the sentence may sound different in focus:

• Mi kedvező döntést várunk. = We are awaiting a favorable decision.
  (emphasis on we)

• Kedvező döntést várunk, nem halasztást. = We are awaiting a favorable decision, not a postponement.
  (strong contrast)

So the original order is not random: it helps show what the sentence is focusing on.

It is singular.

• döntés = decision
• döntést = decision (singular accusative)

If it were plural, you would have a different form, for example:

• döntéseket = decisions (plural accusative)

So this sentence refers to a favorable decision or favorable decision in the singular, depending on context.
