Hi folks,

I'm trying to add a "translate" link to [[:ro:Template:Ill-wd]] (which indicates a subject by it's wikidata id) and I need to determine the original language. Is there a way to determine if the current user prefers/knows some languages except the wiki's own language? I know I can use the interface language, but for the vast majority of users that's identical to the content language.

I vaguely remember that Content Translation asked be at some point about what languages it should use to provide suggestions, but I can't find that setting now. Does it still exist and is it available somehow from outside CX?

Are there any other data sources I can use (and which don't ruin caching, either)?

Thanks,
