Questions & Answers about Masz może jakąś chusteczkę? Od rana kicham i trochę kaszlę.
Both are possible.
- Masz może jakąś chusteczkę? = very natural in everyday speech
- Czy masz może jakąś chusteczkę? = also correct, a bit more explicit as a yes/no question
In Polish, you can often make a yes/no question with just intonation, without adding a separate word like English do.
So Masz...? is simply Do you have...?
Here może does not literally mean maybe in the full English sense. It is a softening particle.
Masz może jakąś chusteczkę? means something like:
- Do you maybe have a tissue?
- Do you happen to have a tissue?
- Would you by any chance have a tissue?
It makes the request sound less direct and more polite/casual.
