czy

Reported Yes-Or-No Questions

Level 3

In Polish, reported (indirect) questions that expect a 'yes' or 'no' answer are introduced by the particle czy. It is always preceded by a comma.

How It Works

When you want to report a question like 'Are you hungry?' or 'Will he come?', you use a subordinate clause starting with czy.

1. The Role of 'Czy'
In this context, czy acts as a complementizer. While it is often optional in direct spoken questions (where intonation does the work), it is obligatory in reported questions. It translates to both 'if' and 'whether' in English.

2. Punctuation
Polish orthography is strict: you must place a comma before the czy that introduces the reported question. For example: Nie wiem, czy...

3. Word Order and Tense
Polish is simpler than English in two ways here:

  • No Inversion: You keep the standard declarative word order within the czy clause.
  • No Tense Backshift: If the original question was in the present tense, the reported question stays in the present tense, even if the main verb (like 'asked') is in the past.

4. 'Czy' vs. 'Jeśli'
A common mistake for English speakers is using jeśli (if) to report a question. In Polish, jeśli is only for conditions (e.g., 'If it rains, I'll stay home'). For inquiries, always use czy.

  1. Nie wiem, czy on ma czas.

    I don't know if he has time.

    Word by Word: Not I-know, whether he has time.

    Notice the comma before 'czy' and the standard word order following it.

  2. Zapytał, czy jestem głodny.

    He asked if I am hungry.

    Word by Word: He-asked, whether I-am hungry.

    In Polish, we use the present tense 'jestem' because the original question was 'Are you hungry?'. We do not shift it to the past tense.

  3. Zastanawiam się, czy to prawda.

    I wonder if that is true.

    Word by Word: I-wonder myself, whether that truth.

    The verb 'zastanawiać się' (to wonder) is frequently followed by a 'czy' clause.

  4. Powiedz mi, czy pójdziesz do kina.

    Tell me whether you will go to the cinema.

    Word by Word: Tell me, whether you-will-go to cinema.

    The future tense is preserved in the reported question.

  5. Nie pamiętam, czy zamknąłem drzwi.

    I don't remember if I locked the door.

    Word by Word: Not I-remember, whether I-locked door.

    Here, 'czy' introduces a question about a past action.

Common Mistakes

  • Using 'jeśli' instead of 'czy' for reported questions.

    Nie wiem, jeśli on przyjdzie.
    Nie wiem, czy on przyjdzie.

    'Jeśli' is for conditional 'if' (if X happens, then Y). For questions and uncertainty, 'czy' is the only correct choice.

  • Omitting the comma before 'czy'.

    Zapytała czy lubię kawę.
    Zapytała, czy lubię kawę.

    In Polish, subordinate clauses starting with 'czy' must be separated from the main clause by a comma.

  • Backshifting the tense when the question was about now.

    Different MeaningZapytał, czy byłem zmęczony.
    Zapytał, czy jestem zmęczony.

    'Zapytał, czy byłem zmęczony' is a good sentence, but it asks whether you were tired at some earlier time. If the question was 'Are you tired?', Polish keeps the present tense: 'Zapytał, czy jestem zmęczony.'
