Questions & Answers about Czy masz już umówioną wizytę u dentysty?
Czy is a question particle. It signals that the sentence is a yes/no question.
So:
- Masz już umówioną wizytę u dentysty. = You already have a dentist appointment arranged.
- Czy masz już umówioną wizytę u dentysty? = Do you already have a dentist appointment arranged?
Unlike English, Polish does not need an auxiliary like do to form this kind of question. You can often ask the same question just by using intonation:
- Masz już umówioną wizytę u dentysty?
That is also natural in speech.
Masz is the 2nd person singular form of mieć (to have), so it means you have.
- mam = I have
- masz = you have
- ma = he/she/it has
The sentence literally uses the idea Do you have an appointment arranged already?, not Are you arranged an appointment.
So:
- Czy masz... ? = Do you have... ?
