In this lesson, students learned about the usage of formal and informal language in Italian. The formal form, known as “forma di cortesia,” involves using the third person singular and is employed to show respect or when interacting with unfamiliar individuals, marked by phrases like “dare del Lei.” Conversely, the informal form, or “dare del tu,” uses the second person singular and is suitable for friends or family, illustrated by relaxed greetings and exchanges such as “Ciao Mario, come stai?” which means “Hi Mario, how are you?” in English.
