How do you say hi my name is Allie in french?

There are a few ways to say "Hi, my name is Allie" in French, depending on the context and formality:

Formal:

* Bonjour, je m'appelle Allie. (This is the most common and formal way to introduce yourself.)

Informal:

* Salut, je m'appelle Allie. (This is a more casual way to say hello.)

* Coucou, je m'appelle Allie. (This is very informal, like saying "Hey" in English.)

You can also use the following:

* Bonjour, je suis Allie. (This is also formal, but emphasizes "I am Allie" rather than "My name is Allie.")

Important Note: In French, it is common to use the formal "vous" when addressing someone you don't know well, even if they are your age. It's best to stick to the formal forms of greeting until you are familiar with the person.
