A természeti kár jelentős.

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

So A természeti kár jelentős literally looks like The natural damage significant, but it means The natural damage is significant.

You would see an overt verb in other tenses, for example: A kár jelentős volt = The damage was significant.

A is the definite article, so it means the.

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

So:

• a kár = the damage
• az eső = the rain

Unlike English, Hungarian articles do not show gender, because Hungarian has no grammatical gender.

Because the two adjectives have different jobs.

természeti is an attributive adjective: it directly modifies the noun kár, so it stands before the noun:

• természeti kár = natural damage

jelentős is a predicate adjective: it tells you something about the whole subject:

• A természeti kár jelentős = The natural damage is significant

So the structure is roughly:

• A természeti kár = the subject
• jelentős = what is being said about it

Természeti comes from természet = nature.

The ending -i often makes an adjective meaning related to, belonging to, or connected with something.

So természeti means related to nature or of nature.

In this sentence, természeti kár means damage connected with natural forces, such as storms, floods, hail, or earthquakes.

Because természeti and természetes are similar but not the same.

• természeti = related to nature, of the natural world
• természetes = natural in the sense of normal, ordinary, not artificial

So természeti kár is the standard expression for damage caused by nature.

Természetes kár would sound odd, because it could suggest something like damage that is natural/normal, which is not what is meant.

Yes. Kár is often used like English damage, which is frequently treated as an uncountable idea.

So singular kár can refer to damage in general, not just one single countable item.

If you want to talk about multiple separate losses or damages, Hungarian can also use the plural károk.

For example:

• A kár jelentős = The damage is significant
• A károk jelentősek = The damages/losses are significant

Only partly, depending on position.

When an adjective comes before a noun, it does not normally change for plural:

• jelentős kár
• jelentős károk

But when the adjective is the predicate, it often shows plural if the subject is plural:

• A kár jelentős = singular
• A károk jelentősek = plural

So in your sentence, jelentős is singular because kár is singular.

Yes. Hungarian word order is flexible and often reflects focus and information structure, not just grammar.

A természeti kár jelentős is a straightforward, neutral way to say it, with A természeti kár as the topic and jelentős as the comment.

You could also say:

• Jelentős a természeti kár.

That version puts more emphasis on jelentős.

Both are grammatical, but the emphasis is slightly different.

In Hungarian, the main stress is always on the first syllable of each word.

So you stress:

• A
• TERmészeti
• KÁR
• JElentős

A few useful pronunciation points:

• j is like English y
• sz is like English s
• s is like English sh
• á, é, ő are long vowels

So:

• természeti starts with stressed TER-
• jelentős starts with YE-, and the final s sounds like sh

That means jelentős sounds roughly like YE-len-tősh.
