When greeting locals in Florence, you can use the most common Italian greetings. In the morning, say "Buongiorno", which means "Good morning". From late morning to evening, say "Buonasera," which translates to "Good evening." Use "Ciao" as a casual greeting for both "Hello" and "Goodbye." To show respect in a more formal situation, greet the person by their title, such as "Signore" for men or "Signora" for women, followed by their last name. A warm smile and friendly demeanor will be appreciated in any case.
