Ściągacz jest zniszczony.

A rough pronunciation guide is:

ŚCIĄ-gacz jest zni-SZCZO-ny

A few sound notes:

• ś is a soft sh sound.
• cią has a soft ć sound plus ą, which is a nasal vowel.
• cz sounds like English ch, but a bit harder.
• jest is pronounced yest.
• zniszczony has szcz, which sounds like a combination of shch.

Polish stress is usually on the second-to-last syllable, so here the stressed syllables are ŚCIĄ- and -SZCZO-.

Ściągacz is masculine singular, because it ends in a consonant and belongs to a masculine noun pattern.

Because of that, the describing word must match it:

• masculine singular: zniszczony
• feminine singular: zniszczona
• neuter singular: zniszczone

So:

• Ściągacz jest zniszczony.
• Maszyna jest zniszczona.
• Urządzenie jest zniszczone.

This is just normal adjective agreement.

In standard Polish, jest is normally used in a sentence like this.

So the natural full sentence is:

Ściągacz jest zniszczony. = The extractor / cheat sheet / etc. is damaged/destroyed.

Leaving out jest is usually not standard in an ordinary sentence. You might see omission in:

• notes
• headlines
• very informal speech
• poetic style

But for a learner, the safe rule is: keep jest.

It is originally a passive participle from the verb zniszczyć (to destroy, to damage, to ruin), but in sentences like this it often works very much like an adjective.

So in practice, you can think of it as meaning:

• destroyed
• damaged
• ruined
• worn out

In Ściągacz jest zniszczony, it describes the state of the object.

A useful contrast:

• Ściągacz jest zniszczony = it is in a destroyed/damaged state
• Ściągacz został zniszczony = it got destroyed / it was destroyed

The second version focuses more on the event.

This is a very common question.

In Polish, after być (to be):

• nouns are often in the instrumental
• adjectives are not; they agree normally with the subject

Compare:

• On jest lekarzem. = He is a doctor.
  (lekarzem is a noun in the instrumental)
• On jest zmęczony. = He is tired.
  (zmęczony is an adjective-like form agreeing with on)

So in your sentence:

• ściągacz = subject
• zniszczony = adjective/participle describing it

That is why you get zniszczony, not zniszczonym.

It is in the nominative singular.

Why? Because it is the subject of the sentence:

Ściągacz jest zniszczony.
= The ściągacz is destroyed/damaged.

The nominative is the basic dictionary form, and that is what you see here.

Yes. Ściągacz can have different meanings depending on context. For example, it can refer to:

• a puller / extractor tool
• a cheat sheet
• sometimes another object connected with pulling or removing

So the grammar of the sentence stays the same, but the exact English translation depends on context.

That is normal in Polish: one noun can have several related meanings.

The given order is the most neutral and natural one.

Polish word order is flexible, so other orders are possible, but they change the emphasis:

• Ściągacz jest zniszczony. = neutral
• Zniszczony jest ściągacz. = emphasizes zniszczony or sounds more literary/contrastive

For most learners, the safest choice is the neutral pattern:

subject + jest + description

It depends on context.

Zniszczony is a broad word and can mean:

• destroyed
• badly damaged
• ruined
• worn out

It often suggests more than a small defect.

Useful comparison:

• uszkodzony = damaged
• zepsuty = broken, not working
• zniszczony = ruined/destroyed/worn out

So if something is scratched or harmed, uszkodzony may fit. If it does not work, zepsuty may fit. If it is really ruined or badly worn, zniszczony is often best.

Yes, very much.

The correct spelling is:

Ściągacz jest zniszczony.

The letters Ś and ą are real Polish letters, not optional decorations. They affect pronunciation and are part of standard spelling.

You may sometimes see people type without diacritics online:

Sciagacz jest zniszczony

But that is nonstandard and should not be copied in careful writing. As a learner, it is best to write the proper Polish characters whenever possible.
