A felső polc üres.

A is the Hungarian definite article, so here it means the.

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

So:

• a felső polc = the top shelf
• but az asztal = the table

Since felső starts with f, a consonant, the correct form is a.

In this sentence, Hungarian leaves out the verb to be in the present tense, third person singular.

So:

• A felső polc üres.
  literally: The top shelf empty.
  natural English: The top shelf is empty.

This is completely normal in Hungarian.

Compare:

• Én üres vagyok. = I am empty.
• Te üres vagy. = You are empty.
• A polc üres. = The shelf is empty.
  → no van here

But in other tenses, the verb appears:

• A polc üres volt. = The shelf was empty.

Because felső and üres are doing different jobs in the sentence.

1. felső is an attributive adjective

It directly describes the noun as part of the noun phrase:

• a felső polc = the upper/top shelf

In Hungarian, adjectives normally come before the noun in this use.

2. üres is a predicate adjective

It tells you something about the shelf:

• A felső polc üres. = The top shelf is empty.

So it comes in the predicate position, after the noun phrase.

A useful contrast:

• az üres polc = the empty shelf
• A polc üres. = The shelf is empty.

Felső means upper or top.

So a felső polc can mean:

• the upper shelf
• the top shelf

The best English translation depends on context.

It contrasts with words like:

• alsó = lower / bottom
• középső = middle

Examples:

• a felső polc = the top shelf
• az alsó polc = the bottom shelf

A rough pronunciation guide:

• felső ≈ fel-shuh
• üres ≈ something like ew-resh, but with Hungarian ü, which is not exactly like English ew

A few important sound notes:

• s in Hungarian is pronounced sh
• sz is pronounced s
• ő is a long rounded vowel
• ü is a rounded front vowel, similar to German ü if you know it

So:

• felső → the s sounds like sh
• üres → the s also sounds like sh

Also, Hungarian stress is usually on the first syllable:

• FEL-ső
• Ü-res

Yes. Üres a felső polc is also correct.

Both sentences mean basically the same thing:

• A felső polc üres.
• Üres a felső polc.

The difference is mostly about focus or emphasis.

Neutral statement

• A felső polc üres.
  = The top shelf is empty.

More emphasis on empty

• Üres a felső polc.
  = The top shelf is empty / It’s the top shelf that’s empty

Hungarian word order is flexible, but it often reflects what part of the sentence is most important.

Here, polc is singular: shelf.

So:

• polc = shelf
• polcok = shelves

Examples:

• A polc üres. = The shelf is empty.
• A polcok üresek. = The shelves are empty.

Notice that in the plural sentence, the adjective also becomes plural:

• üres → üresek

In Hungarian, attributive adjectives usually do not agree with the noun the way they do in some other languages.

So you say:

• a felső polc = the upper shelf
• a felső polcok = the upper shelves

The adjective felső stays the same.

This is normal in Hungarian. The noun carries the plural marking, not the adjective.

Yes, but not in this sentence.

Here it stays as üres because the subject is singular:

• A felső polc üres. = The top shelf is empty.

With a plural subject, the predicate adjective is often plural too:

• A felső polcok üresek. = The top shelves are empty.

So:

• singular: üres
• plural: üresek

This is something learners often notice because Hungarian adjectives behave differently depending on whether they are:

• before a noun: usually no plural marking
• used as the predicate: plural marking can appear

Yes. A felső polc refers to a specific shelf: the top shelf.

If you wanted an indefinite version, you would use egy:

• Egy felső polc üres. = A top shelf is empty. / One upper shelf is empty.

But in many real situations, a felső polc is more natural because speakers often mean a particular shelf that both people can identify.

Usually felső polc means upper shelf or top shelf, not just any shelf that happens to be high.

If you want to describe physical height more directly, other wording may be used depending on context. But felső mainly expresses relative position within a set:

• upper vs lower
• top vs bottom

So if there are several shelves, a felső polc is the one above the others.
