Canon in this context has two main meanings:
* Official: "You are official," "You are recognized," or "You are legitimate." This is used to acknowledge something or someone as part of an established group, system, or narrative.
* Fanfiction: In fan communities, particularly for media like movies, TV shows, or books, "canon" refers to the original storyline, characters, and events as created by the original creators. So, "tu es canon" could mean that the person is considered an official part of the fictional world, like a character or event.
Example:
* Official: If someone is officially appointed to a position, you could say "Tu es canon maintenant" (You are officially appointed now).
* Fanfiction: If someone writes a story that closely follows the established plot of a TV show, a fan might say, "Ton histoire est canon" (Your story is canon).
The specific meaning of "tu es canon" depends on the context. If you're unsure, it's always best to ask for clarification.
