Really excellent, we "lol'd" a lot here
I loved in particular the part about Shakespeare, it remembered me an episode of "Les deux minutes du peuple" by François Pérusse, about "
l'Académie française". (in French, sorry)
Languages' evolution is very fascinating, whatever the language.
I remember I learned once that a "Flirt" (used in French) comes from "flirting", which comes from an old French expression "Compter-fleurette" (pronounce "count-ay-flore-ate"

) =)
