Thread creep, but so be it.

On the subject of "yes", "oui" etc.

There is a section of southern France called the Languedoc. This goes back to the language of that area, which was a major division of Medieval French. That area of France had a higher cultural significance or status than the northern part, was what you might call "the high culture" of France of the time. (Now, finally getting to the subject) The word for "yes" in that language was "oc", whereas the rest of France said "oui". The languages were referred to respectively as "la langue d
oc" and "la langue d'oui". After the violent suppression of the Albigensian heresy, that part of France never really recovered, and the language pretty much went by the wayside, but the name of the province still recalls what they once said for "yes".
