A kép homályos.

A is the definite article, so it means the.

Hungarian has two forms of the definite article:

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

Since kép starts with k, you say a kép.

Examples:

• a kép = the picture
• az alma = the apple

In Hungarian, the verb to be is usually omitted in the present tense, third person singular when the predicate is a noun or an adjective.

So:

• A kép homályos. = The picture is blurry.

Hungarian does not normally say A kép homályos van here.

But in other tenses, the verb appears:

• A kép homályos volt. = The picture was blurry.
• A kép homályos lesz. = The picture will be blurry.

Because here homályos is the predicate adjective: it tells you something about the picture.

So:

• A kép homályos. = The picture is blurry.

If you want blurry picture as a noun phrase, the adjective goes before the noun:

• egy homályos kép = a blurry picture

So the difference is:

• homályos kép = blurry picture
• A kép homályos. = The picture is blurry.

In modern standard Hungarian, ly is pronounced the same as j, roughly like the y in yes.

So homályos is pronounced approximately:

• HO-maa-yosh

A few useful pronunciation points:

• á is a long vowel
• ly sounds like y
• s sounds like sh in Hungarian

So homályos sounds roughly like ho-MAA-yosh, with the stress on the first syllable of the word.

A rough English-friendly pronunciation is:

• A kép homályos → uh kayp HO-maa-yosh

More exactly:

• a = a short open vowel
• kép = long é, roughly kayp
• homályos = HO-maa-yosh

Also, Hungarian normally stresses the first syllable of each word.

Besides blurry, homályos can also mean things like:

• fuzzy
• hazy
• unclear
• sometimes even vague in a more abstract sense

So it can describe something visually unclear, but in other contexts it can also mean that something is not clear in meaning or detail.

Yes. That is also natural Hungarian.

Both are correct, but the emphasis changes:

• A kép homályos. = neutral statement
• Homályos a kép. = puts more focus on blurry

English often translates both the same way, but Hungarian word order often helps show what is being emphasized.

You use nem:

• A kép nem homályos. = The picture is not blurry.

In Hungarian, nem usually comes right before the part it negates.

Then you make both the noun and the predicate adjective plural:

• A képek homályosak. = The pictures are blurry.

Here:

• kép → képek = picture → pictures
• homályos → homályosak = plural predicate adjective

But notice this important contrast:

• homályos képek = blurry pictures
  (adjective before the noun, no plural ending on the adjective)
• A képek homályosak. = The pictures are blurry
  (predicate adjective, so it takes a plural ending)
