Someone was asking on the English language site, what is meant by “cream of the crop?” . An answerer speculated, that the origin might be French.
If I asked, “How do you say ‘cream of the crop’?” in French on this site, would that be considered a "duplicate" question? Of course, the answer would be in French, which might make it a non-duplicate. And while I “suspect” the origin might be French, I'm not really sure.
