A kárszakértő felméri a viharkárt.

A is the Hungarian definite article, equivalent to the.

It appears twice because both kárszakértő and viharkárt are specific:

• A kárszakértő = the claims adjuster / the damage expert
• a viharkárt = the storm damage

Hungarian uses:

• a before a consonant sound
• az before a vowel sound

So here it is a both times because kárszakértő and viharkárt both begin with consonant sounds.

Kárszakértő is a compound noun:

• kár = damage, loss
• szakértő = expert, specialist

So literally it means damage expert. In real-world usage, it often corresponds to claims adjuster or damage assessor, especially in insurance contexts.

Felméri means assesses, surveys, or evaluates.

Its dictionary form is felmér = to assess / to survey.

In this sentence, it means that the expert is examining the damage and determining its extent.

Because Hungarian verbs change depending on whether they take a definite object.

Here the object is a viharkárt = the storm damage, which is definite, so the verb uses the definite conjugation.

• felmér = he/she assesses something indefinite, or just assesses
• felméri = he/she assesses it / the specific thing

So:

• A kárszakértő felmér egy kárt. = The expert assesses a damage/loss.
• A kárszakértő felméri a kárt. = The expert assesses the damage.

Because viharkárt is the direct object of the sentence, and Hungarian usually marks the direct object with -t.

• viharkár = storm damage
• viharkárt = storm damage (as the object)

So the -t here is the accusative ending.

This is one of the most important Hungarian case endings to learn.

It is another compound noun:

• vihar = storm
• kár = damage

So viharkár literally means storm damage.

Hungarian forms many everyday nouns this way by combining two words into one compound.

Because fel- is a verbal prefix, and in a neutral statement it is usually attached directly to the verb.

So:

• felméri = assesses

But Hungarian prefixes can separate in some sentence types, especially with:

• negation
• focus
• certain word orders

For example:

• Nem méri fel a viharkárt. = He/She does not assess the storm damage.
• A viharkárt méri fel. = It is the storm damage that he/she assesses.

So in your sentence, the joined form felméri is the normal neutral one.

This is a very normal, neutral Hungarian word order:

A kárszakértő felméri a viharkárt.
= The damage expert assesses the storm damage.

It is basically:

• subject
• verb
• object

Hungarian word order is more flexible than English, but changes in order often change focus or emphasis, not just style.

So this sentence sounds like a plain factual statement, with no special contrast.

The special marks matter in Hungarian, because vowel length and quality can change the word.

Useful parts here:

• á = a long vowel, roughly like a longer open a
• é = a long ay-like vowel
• ő = a long rounded front vowel, with no exact English equivalent
• í = a long ee sound

So:

• kár has a long á
• szakértő has é and ő
• felméri has é and í

In Hungarian, these are not optional spelling details; they are full parts of the word.

In this sentence, the noun changes for the object case, but the article does not.

So you get:

• a viharkár = the storm damage
• a viharkárt = the storm damage (object)

Notice that a stays the same, while viharkár takes -t.

This is different from some other languages where the article also changes. In Hungarian, the case ending normally goes on the noun itself.
