Here are some other options, depending on the context:
* "Dzień dobry" (pronounced "DZEN DO-bree") - "Good day" - Formal, used when addressing someone you don't know well or in a professional setting.
* "Witam" (pronounced "VEE-tam") - "Greetings" - A more formal way to say hello.
* "Witaj" (pronounced "VEE-tay") - "Welcome" - More personal than "Witam," often used when greeting someone you know well.
You can also use "Siema" (pronounced "SEE-ma") - It's a very casual, informal greeting, similar to "Hey."
Remember, it's always best to use the most appropriate greeting for the situation.
