What's the difference between formal and informal in Italian?"}, {"role": "assistant", "content": "In Italian, the formal way of speaking is used when addressing people you don't know well, or to show respect, such as when speaking to someone who is older or in a position of authority. The informal way of speaking is used with friends, family, and people you're familiar with. Using the correct form is important in Italian culture, as it shows respect and politeness."}]
