What is arrivederci?

"Arrivederci" is an Italian word commonly used as a farewell expression, similar to "goodbye" in English. It is more formal than "ciao," which can mean both "hello" and "goodbye." The term "arrivederci" is derived from the phrase "a rivederci," which translates to "until we see each other again" or "until we meet again." It is often used when parting ways with someone, with the implication that you hope or expect to see them again in the future.
