How do you address a widowed Italian woman?

In Italian, a widowed woman is often addressed as "signora," which translates to "Mrs." or "madam." If you know her name, you can say "Signora [Last Name]." In more formal contexts, you might refer to her as "Signora" followed by her first name or full name. It’s also respectful to acknowledge her status by using her last name with a gentle tone, depending on the situation.
