What is the anwser to De quelle nationalité es-tu?

The answer to "De quelle nationalité es-tu?" depends on who you are asking. It's a question asking "What is your nationality?"

To answer correctly, you need to provide your own nationality. For example:

* Je suis français. (I am French.)

* Je suis américaine. (I am American.)

* Je suis canadienne. (I am Canadian.)

So, you need to replace the example with your actual nationality.
