A karc fontos szempont a vevőnek.

Hungarian often omits the verb to be in the present tense, third person.

So:

• A karc fontos szempont a vevőnek.
• literally: The scratch important consideration for the buyer.
• natural English: The scratch is an important consideration for the buyer.

This happens very often in Hungarian:

• A ház nagy. = The house is big.
• Ő tanár. = He/She is a teacher.

But the verb does appear in other persons:

• Én tanár vagyok. = I am a teacher.
• Te tanár vagy. = You are a teacher.

So in your sentence, the missing is is completely normal.

The ending -nek is the dative ending. It often means something like:

• to
• for
• sometimes for someone / in someone’s view / to someone

So:

• vevő = buyer
• vevőnek = to the buyer / for the buyer

In this sentence, a vevőnek means something like for the buyer or from the buyer’s point of view.

This is a very common Hungarian pattern:

• fontos valakinek = important to someone
• draga valakinek = dear to someone
• világos valakinek = clear to someone

Examples:

• Ez fontos nekem. = This is important to me.
• Ez világos a diáknak. = This is clear to the student.

So a vevőnek is not possession here. It marks the person for whom something is important.

Because Hungarian often uses the definite article when talking about a specific person or a contextually known person.

• vevőnek = to a buyer / for a buyer
• a vevőnek = to the buyer / for the buyer

Whether English would use the, a, or even no article at all depends on context, but Hungarian often prefers the article when the noun is understood as definite or identifiable in the situation.

For example, in a sales context, a vevő may simply mean the buyer/customer currently being discussed.

So:

• A karc fontos szempont a vevőnek. = The scratch is an important consideration for the buyer.

If you removed the article, it would sound more like a more general statement about buyers in general, depending on context.

Because a karc is being treated as a definite noun: the scratch.

• karc = scratch
• a karc = the scratch

Hungarian uses articles somewhat differently from English, but in this sentence the speaker is probably referring to a specific scratch that both speaker and listener know about.

For example, imagine people discussing the condition of a used car or a product. Then a karc naturally means that scratch / the scratch.

If you said:

• Karc fontos szempont...

that would sound unnatural here.

Hungarian has two forms of the definite article:

• a
• az

Which one you use depends on the sound that follows:

• a before a consonant
• az before a vowel

So:

• a karc because karc starts with k
• a vevőnek because vevőnek starts with v

Compare:

• a ház = the house
• az autó = the car
• az ember = the person
• a bolt = the shop

It works a lot like a/an in English, except Hungarian uses it with the definite article.

Szempont means aspect, point of view, consideration, or factor, depending on context.

In this sentence, fontos szempont means:

• an important factor
• an important consideration
• an important aspect

So the structure is basically:

• A karc = the scratch
• fontos szempont = an important factor/consideration
• a vevőnek = for the buyer

Very literally:

• The scratch [is an] important consideration for the buyer.

This is a useful noun to learn, because Hungarian uses it a lot in practical speech:

• Ez fontos szempont. = This is an important consideration.
• Anyagi szempontból... = From a financial point of view...

In this sentence:

• A karc is the subject
• fontos szempont is the predicate noun phrase
• a vevőnek is a dative complement

So the basic structure is:

• A karc
  • fontos szempont
    • a vevőnek
• The scratch
  • is an important consideration
    • for the buyer

This kind of sentence is very common in Hungarian, especially with omitted is.

You can think of it as:

• X fontos Y valakinek
• X is an important Y to/for someone

Here:

• X = a karc
• Y = szempont
• valakinek = a vevőnek

Yes. Hungarian word order is quite flexible, and changing it often changes the focus or emphasis, not just the basic meaning.

The original:

• A karc fontos szempont a vevőnek.

This is a fairly neutral way to present the information.

But you could also say:

• A vevőnek fontos szempont a karc.
  • This puts more attention on for the buyer
• Fontos szempont a vevőnek a karc.
  • This can sound more like The scratch is an important consideration for the buyer

All of these are possible in the right context, but they do not feel exactly identical in emphasis.

For learners, the original sentence is a good neutral model.

Not exactly, though they overlap.

vevő most literally means:

• buyer
• purchaser

It focuses on the person as someone who buys something.

By contrast, customer is often:

• vásárló = shopper, purchaser
• ügyfél = client/customer, especially for services
• sometimes vevő, depending on context

So in your sentence, a vevőnek is best understood as for the buyer.

That makes sense if people are evaluating a product and considering what matters to the person who might buy it.

Yes, it could be plural, but singular is natural here.

• fontos szempont = an important consideration / factor
• fontos szempontok = important considerations / factors

The singular works because the sentence is saying that the scratch counts as one important factor among the things the buyer considers.

If you made it plural, you would need a different structure, for example:

• A karc fontos szempont a vevőnek. = The scratch is an important consideration for the buyer.

But if you wanted plural, you would usually need to change more of the sentence, because the scratch itself is just one thing, not several considerations.

So singular is the natural choice here.

karc is pronounced roughly like:

• kaarts in English-style approximation

A few useful points:

• a in Hungarian is a short vowel, somewhat like the o in British hot, though exact pronunciation depends on accent comparisons
• r is rolled or tapped
• c in Hungarian is pronounced ts

So:

• karc sounds approximately like karts or kahts, but with a clear ts sound at the end

That final c = ts is very important in Hungarian:

• c = ts
• cs = ch

So:

• karc = roughly karts
• not like English kark

Hungarian has two versions of this suffix:

• -nak
• -nek

Which one you choose depends on vowel harmony.

Very roughly:

• words with back vowels usually take -nak
• words with front vowels usually take -nek

The word vevő has front vowels, so it takes:

• vevő + nek = vevőnek

Compare:

• fiú → fiúnak
• tanár → tanárnak
• nő → nőnek
• vevő → vevőnek

This is a core pattern in Hungarian grammar, and you will see it with many suffixes.

Yes, that is possible in some contexts:

• A karc fontos szempont a vevő számára.

This means something like:

• The scratch is an important consideration for the buyer
• The scratch is an important factor from the buyer’s point of view

Both a vevőnek and a vevő számára can work, but they are not always identical in tone.

• a vevőnek is shorter and very natural
• a vevő számára can sound a bit more formal or explicit

In everyday Hungarian, the dative with -nek/-nak is very common after adjectives like fontos.
