What does ciao mean in Italian?

"Ciao" in Italian means hello or goodbye. It's a very versatile greeting that can be used in both formal and informal settings.

Here are some examples:

* Ciao, come stai? (Hello, how are you?)

* Ciao, mi chiamo Marco. (Hello, my name is Marco.)

* Ciao, a presto! (Goodbye, see you soon!)

* Ciao, è stato un piacere incontrarti. (Goodbye, it was nice meeting you.)

It's important to note that "ciao" is considered informal. In more formal situations, it's better to use "buongiorno" (good morning), "buonasera" (good evening), or "arrivederci" (goodbye).
