Where does $user->language info come from ?

[Doc]

Hello,

I'm wondering how that variable is filled up ?

$user->language

Language

User language, applicable only if LanguageSupport installed.

It says 'fr' for me, and it's the default language I chose for the website I'm building, is it taken from here ?

Thanks

It's the language choosen for that user in the backend. For non logged-in users it's the language of the guest user.

OK... I didn't know the guest user was associated with a language. I've just checked in the admin and it's 'fr', mystery solved, thanks !
