Köszönjük a barátunknak a segítséget.

A useful breakdown is:

• köszön-jük = thank
  • we with the definite verb ending
• a = the
• barát-unk-nak = friend
  • our
    • to/for
• a = the
• segítség-et = help
  • accusative marker

So the sentence is built as:

We-thank + to-our-friend + the-help

That structure is more natural in Hungarian than copying the English pattern exactly.

Because Hungarian has two main conjugation patterns for many verbs:

• indefinite conjugation
• definite conjugation

Here, the direct object is a segítséget, which is a definite object, so the verb uses the definite 1st person plural form:

• köszönünk = we thank / we say hello, with no definite direct object
• köszönjük = we thank it / the specific thing

So köszönjük is used because a segítséget is specific and definite.

This is one of the biggest differences from English.

In English, you say thank our friend and the person is the direct object.

In Hungarian, with this structure, the person is treated as an indirect object and gets the dative ending:

• -nak / -nek = to / for

So:

• barátunknak = to our friend
• a segítséget = the thing being thanked for, the direct object

In other words, Hungarian is using something closer to thank to our friend the help in structure, even though that is not natural English.

It has three parts:

• barát = friend
• -unk = our
• -nak = to/for

So:

• barátunk = our friend
• barátunknak = to/for our friend

This kind of stacking is very normal in Hungarian. A noun can take both a possessive ending and a case ending.

Because Hungarian can still use the definite article with possessed nouns.

So a barátunk is perfectly normal and means our friend as a specific, identifiable person.

English usually does not say the our friend, but Hungarian does allow:

• a barátunk = our friend
• a házunk = our house

The article is not redundant in Hungarian; it is part of how definite noun phrases are commonly formed.

The important case ending here is -t, which marks the accusative case, the direct object.

But Hungarian often inserts a linking vowel before -t when the word would otherwise be awkward to pronounce.

So:

• base noun: segítség
• accusative: segítség + et
• result: segítséget

The vowel is e because the word has front vowels, so it follows vowel harmony.

So the key idea is:

• -t = accusative
• -e- = linking vowel for pronunciation and harmony

Because each definite noun phrase gets its own article.

Here you have two separate noun phrases:

• a barátunknak
• a segítséget

Both are definite, so both take a.

Hungarian does not usually share one article across two separate nouns the way learners sometimes expect.

No, Hungarian word order is quite flexible, but different orders can change focus or emphasis.

This sentence order is a normal, natural one:

• Köszönjük a barátunknak a segítséget.

It presents the event in a straightforward way.

If you move parts around, the sentence can still be grammatical, but the emphasis changes. For example, putting a barátunknak earlier can highlight our friend, and putting a segítséget earlier can highlight the help.

So the order is not random, but it is also not as rigid as English word order.

It is singular.

• barát = friend
• barátunk = our friend

So barátunknak means to our friend, singular.

If you wanted to our friends, you would need a plural form, for example:

• barátainknak = to our friends

So the -unk ending does not mean the noun itself is plural. It only shows that the possessor is we / our.

Yes. köszön can also mean greet or say hello depending on the structure.

For example:

• Köszönünk a barátunknak. can mean We greet our friend or We say hello to our friend.

But in your sentence, because there is also a segítséget, the meaning is clearly about thanking.

So the extra object helps remove ambiguity:

• köszön valakinek = greet someone / say hello to someone
• köszön valakinek valamit = thank someone for something
