Formal:
* Bonjour, Maddie. (This is the most common and polite way to greet someone.)
Informal:
* Salut, Maddie. (This is a more casual greeting, similar to "hi" in English.)
* Coucou, Maddie. (This is a very informal greeting, often used between friends.)
If you know Maddie well, you could also use:
* Hey Maddie! (This is a more casual and friendly greeting.)
Important:
* In French, it's important to use the appropriate form of address. If you're unsure, it's always better to be formal.
* French speakers often use the formal "vous" even when addressing someone they know well, especially in a professional setting.
I hope this helps!
