Kto jest winny?

A natural pronunciation is roughly:

kto yest VIN-nih?

A bit more precisely:

• kto = kto (the k and t are both pronounced)
• jest = yest
• winny = VEEN-nih

Notes:

• w in Polish sounds like English v
• j sounds like English y
• y is a short vowel that does not exist exactly in English; nih is only an approximation
• Stress falls on the second-to-last syllable: WIN-ny

Word by word:

• kto = who
• jest = is
• winny = guilty / at fault / to blame

So the structure is very close to English:

Who + is + guilty?

Jest is the 3rd person singular form of być (to be), so it means is.

In standard Polish, Kto jest winny? is the normal full sentence.

You may sometimes hear the shortened Kto winny?, especially in casual speech, headlines, or dramatic contexts, but that is elliptical. For learners, the safe standard form is:

Kto jest winny?

Because winny agrees with kto, and kto takes masculine singular agreement in Polish.

So even if you are asking about a woman, the question still stays:

Kto jest winny?

This is a grammatical default, not a statement about the real person’s sex.

But in the answer, the adjective changes to match the actual person:

• Anna jest winna. = Anna is guilty.
• Jan jest winny. = Jan is guilty.
• Dziecko jest winne. = The child is guilty / at fault.

Here kto is in the nominative case, because it is the subject of the sentence:

Kto jest winny? = Who is guilty?

You would see other forms in other functions, for example:

• Kogo widzisz? = Whom do you see?
• Komu ufasz? = Whom do you trust?

But in this sentence, kto is the subject, so nominative is correct.

Winny is in the nominative singular masculine form.

After być (to be), Polish often uses the nominative with predicate nouns and adjectives in basic identifying/describing sentences:

• On jest zmęczony. = He is tired.
• To jest trudne. = This is difficult.
• Kto jest winny? = Who is guilty?

So winny matches the grammatical form required by kto.

No. Winny can mean:

• guilty in a legal or moral sense
• at fault
• to blame
• sometimes responsible for something negative

So Kto jest winny? can be used:

• in a courtroom-type context
• after an argument
• after a mistake or accident
• in a figurative sense

For example, it could mean either:

• Who is guilty?
• Who is to blame? depending on context.

The normal and most natural order is:

Kto jest winny?

Polish word order is often flexible, but with a simple question like this, putting kto first is the standard choice.

Other orders are possible only in special contexts, usually for emphasis, contrast, or stylistic effect, but they are not what a learner should start with.

So the best version to remember is:

Kto jest winny?

Some natural answers are:

• Jan jest winny. = Jan is guilty.
• To Jan jest winny. = It’s Jan who is guilty.
• Anna jest winna. = Anna is guilty.
• Nie wiem, kto jest winny. = I don’t know who is guilty.
• Nikt nie jest winny. = No one is guilty.
• Wszyscy są winni. = Everyone is guilty.

Notice how winny changes:

• winny for masculine singular
• winna for feminine singular
• winni for masculine personal plural
• winne or winni, depending on the group

It can be either, depending on context.

If the situation is about crime, law, or moral responsibility, guilty is a good translation.

If the situation is about fault in a mistake, argument, or bad outcome, to blame may sound more natural in English.

So:

• legal context: Who is guilty?
• everyday blame context: Who is to blame?

Both fit Kto jest winny?

Yes.

• wina = guilt / fault / blame
• winny = guilty / at fault

They are directly related in meaning.

Examples:

• To nie moja wina. = It’s not my fault.
• On jest winny. = He is guilty / at fault.

A small warning: wino means wine, which looks similar but is a different word.

Normally kto is used for people.

So Kto jest winny? asks which person is guilty or at fault.

If you are asking about a thing or cause rather than a person, Polish would usually use a different structure, for example:

• Co jest przyczyną? = What is the cause?
• Co za to odpowiada? = What is responsible for that?

So with kto, you are basically expecting a human answer.
