A kép éles.

In Hungarian, the verb to be is usually left out in the third person singular and third person plural when talking about something in the present tense.

So:

• A kép éles. = The picture is sharp.
• literally: The picture sharp.

But in other persons, Hungarian does use the verb:

• Éles vagyok. = I am sharp
• Éles vagy. = You are sharp

And in the past or future, van / volt / lesz etc. can appear as needed.

A is the Hungarian definite article, meaning the.

So:

• a kép = the picture / the image

Hungarian has two forms of the:

• a
• az

Which one is used depends mainly on the following sound:

• a kép because kép starts with a consonant
• az alma = the apple because alma starts with a vowel

It can mean several related things depending on context:

• picture
• image
• sometimes photo, though fotó is also very common for photo

So A kép éles could naturally mean:

• The picture is sharp
• The image is sharp
• in the right context, The photo is sharp

Éles most often means sharp.

Depending on context, that can refer to different kinds of sharpness:

• a sharp image or clear picture
• a sharp knife
• a sharp sound
• even a sharp mind in some contexts

In A kép éles, it means the image is visually sharp / in focus / clear.

That is the normal position in a simple Hungarian sentence like this:

• A kép = the subject
• éles = the predicate adjective

So the structure is basically:

• The picture sharp

Hungarian often puts descriptive words after the noun when they are part of the sentence predicate:

• A ház nagy. = The house is big.
• A leves meleg. = The soup is hot.

But when the adjective directly modifies the noun inside a noun phrase, it comes before the noun:

• az éles kép = the sharp picture

So compare:

• A kép éles. = The picture is sharp.
• Az éles kép = the sharp picture

No. Hungarian adjectives do not agree with nouns the way they do in many European languages.

That means éles stays the same:

• A kép éles. = The picture is sharp.
• A képek élesek. = The pictures are sharp.

In the plural predicate, you often see -k on the adjective:

• élesek = sharp (plural predicate form)

But there is no grammatical gender in Hungarian, so nothing changes for masculine/feminine/neuter, because Hungarian does not have those categories.

A simple approximate pronunciation is:

• a kayp ay-lesh

A bit more carefully:

• a = short aw / uh
• kép = like cape, but shorter and without the English glide
• éles = roughly AY-lesh

A few useful notes:

• é is a long vowel, roughly like ay in say
• s in Hungarian is pronounced sh
• stress is always on the first syllable of each word:
  • A KÉP É-les

Because Hungarian spelling works differently from English.

In Hungarian:

• s = sh
• sz = s

So:

• éles sounds like ay-lesh
• szép sounds like sayp and means beautiful

This is one of the first spelling patterns learners usually need to get used to.

Yes. Ez a kép éles means:

• This picture is sharp.

Here:

• ez = this
• a kép = the picture
• éles = sharp

So the original sentence A kép éles is a simple neutral statement, while Ez a kép éles points to a specific picture more explicitly.

You add nem before the adjective:

• A kép nem éles. = The picture is not sharp.

This is the normal way to negate this kind of sentence in Hungarian.

That would be:

• A képek élesek.

Here:

• kép = picture
• képek = pictures
• éles = sharp
• élesek = sharp (used here with a plural subject)

And the verb are is still omitted in the present tense third person, just like is was omitted in A kép éles.
