Here are some other ways to say hello, depending on the situation:
* "Dzień dobry" (pronounced "DZHEN-dob-ree") - Good day, used for formal greetings.
* "Dobry wieczór" (pronounced "dob-ree VYEH-choor") - Good evening, used for formal greetings in the evening.
* "Witam" (pronounced "VEE-tam") - A more formal greeting, meaning "I greet you".
* "Witaj" (pronounced "VEE-tai") - A slightly less formal greeting, meaning "Welcome".
Remember that Polish pronunciation can be tricky, so it's a good idea to listen to a native speaker to get the correct intonation.
