Ten egzemplarz jest niedostępny.

Egzemplarz means copy, individual экземпляр/item, or specimen, depending on context.

In this sentence, it most often means:

• this copy — for example, a copy of a book, magazine, document, or product unit

So Ten egzemplarz jest niedostępny is something like:

• This copy is unavailable
• This item is unavailable

It is a fairly formal or neutral word. In everyday speech, the exact noun might change depending on the thing being discussed.

Because egzemplarz is a masculine singular noun.

In Polish, this changes to match the gender of the noun:

• ten = masculine
• ta = feminine
• to = neuter

So:

• ten egzemplarz = this copy/item
• ta książka = this book
• to okno = this window

Since egzemplarz is masculine, ten is the correct form.

Usually, yes. A noun ending in a consonant is very often masculine in Polish, and egzemplarz follows that common pattern.

So learners often recognize it as masculine from its ending:

• egzemplarz
• not egzemplarza or egzemplarzo

That helps explain why both ten and niedostępny are in masculine singular form.

Niedostępny is the adjective meaning unavailable, not accessible, or sometimes inaccessible, depending on context.

It agrees with egzemplarz, so it must also be:

• masculine
• singular

That is why you get:

• ten egzemplarz
• jest niedostępny

If the noun changed gender, the adjective would change too:

• ta książka jest niedostępna = this book is unavailable
• to miejsce jest niedostępne = this place is inaccessible/unavailable

Yes. That is exactly how it works.

• dostępny = available / accessible
• niedostępny = unavailable / inaccessible

The prefix nie- is the normal way to negate many adjectives in Polish.

A very common pair is:

• możliwy = possible
• niemożliwy = impossible

So niedostępny is a very natural formation.

Jest is the 3rd person singular of być (to be) and means is.

In this sentence:

• Ten egzemplarz jest niedostępny = This copy is unavailable

In standard full sentences, jest is completely normal and expected.

Polish sometimes drops to be in very informal contexts, headlines, labels, or notes, for example:

• Egzemplarz niedostępny

That can appear on websites, in catalog systems, or in short notices. But as a full normal sentence, jest is correct and natural.

Yes, it is natural, especially in contexts like:

• a library catalog
• a bookstore website
• a product listing
• an archive or database
• a formal notice

It sounds a bit more neutral or formal than very conversational speech because of the noun egzemplarz. In everyday conversation, people might use a more specific noun instead, such as:

• Ta książka jest niedostępna = This book is unavailable
• Ten produkt jest niedostępny = This product is unavailable

But your sentence is absolutely correct and natural.

It is in the nominative singular.

Why?

Because egzemplarz is the subject of the sentence:

• Ten egzemplarz = the thing being talked about

And after być (to be), the adjective niedostępny is also in the nominative here, agreeing with the subject.

So the structure is:

• Ten egzemplarz — nominative singular masculine
• jest
• niedostępny — nominative singular masculine adjective

A rough guide for an English speaker:

• Ten ≈ ten (but with a more pure e vowel)
• egzemplarz ≈ eg-zem-plaʂ
• jest ≈ yest
• niedostępny ≈ nye-do-stem-pnih

A few useful pronunciation notes:

• j in Polish sounds like English y
  • jest ≈ yest
• rz often sounds like zh or sh-like depending on surroundings; in egzemplarz it ends up sounding close to sh
• ni before a vowel often gives a ny sound
  • nie ≈ nye
• ę is nasal, but in real speech before certain consonants it often sounds closer to em/en
  • so dostępny may sound roughly like dostempny

A more phonetic approximation: ten eg-ZEM-plaʂ yest nye-dos-TEMP-nih

Because here niedostępny is not directly modifying the noun inside the noun phrase. It is part of the predicate after jest.

Compare:

1. Ten egzemplarz jest niedostępny.
   = This copy is unavailable.

2. Ten niedostępny egzemplarz...
   = This unavailable copy...

In sentence 1, the adjective comes after jest because it is saying something about the subject.

In sentence 2, the adjective comes before the noun because it directly describes it inside the noun phrase.

Yes. Niedostępny can mean either:

• unavailable
• inaccessible
• not accessible

The exact meaning depends on context.

For egzemplarz, the most likely meaning is unavailable:

• a copy is not available for borrowing, purchase, or use

For places or areas, it more naturally means inaccessible:

• Ten obszar jest niedostępny = This area is inaccessible

So the noun helps determine the most natural English translation.

The plural would be:

• Te egzemplarze są niedostępne.
• These copies are unavailable.

Notice the changes:

• ten → te
• egzemplarz → egzemplarze
• jest → są
• niedostępny → niedostępne

This is a good example of how several words in Polish change together to match number.

The demonstrative and adjective must agree with the noun.

Examples:

• Ta książka jest niedostępna.
  = This book is unavailable.
  (książka is feminine)

• To wydanie jest niedostępne.
  = This edition is unavailable.
  (wydanie is neuter)

So the pattern is:

• masculine: ten ... jest niedostępny
• feminine: ta ... jest niedostępna
• neuter: to ... jest niedostępne

Yes, Polish word order is more flexible than English, though some orders sound more neutral than others.

The most neutral version is:

• Ten egzemplarz jest niedostępny.

You could also hear:

• Niedostępny jest ten egzemplarz.
• Ten egzemplarz niedostępny jest. — grammatically possible, but much less natural in normal speech

Changing word order usually changes emphasis, not the basic meaning.

For learners, the original order is the safest and most natural one to use.

Sometimes, yes, but it depends on the situation.

It is especially common in:

• libraries
• bookstores
• publishing
• museums
• official inventories
• online catalogs

In casual daily conversation, a speaker may prefer a more specific noun:

• Ta książka jest niedostępna = This book is unavailable
• Ten produkt jest niedostępny = This product is unavailable
• Ta sztuka jest niedostępna = This piece/item is unavailable

So egzemplarz is correct and useful, but it sounds a bit more specific to cataloging, books, documents, or individual units.

The main tricky points are:

1. Gender agreement
   English this does not change for gender, but Polish does:

   • ten / ta / to

2. Adjective agreement
   English unavailable stays the same, but Polish changes it:

   • niedostępny / niedostępna / niedostępne

3. Formal vocabulary
   Egzemplarz is not the most basic everyday noun, so learners may not immediately recognize it.

4. Pronunciation
   Words like egzemplarz and niedostępny contain sounds and clusters that are less familiar to English speakers.

Grammatically, though, it is a very useful model sentence: demonstrative + noun + jest + adjective.
