"in heavily accented French, the adopted language of the Romanian aristocracy"

Whilst Romania was seeking and gaining independence during the 19th Century, it looked to France as a model of Enlightenment values and revolutionary zeal.  Romanian and French are both daughter languages of Latin, and France's rich, modern, intellectual culture appealed greatly to a country determined to make itself free and strong.  It used to be said that "ce qui n'est pas clair, n'est pas Français" - what is not clear, is not French - and it seems Romania concurred; French not only became adopted by the aristocracy, but entered the everyday parlance of ordinary people.  It is estimated that 39% of the Romanian language is now borrowed from French.  It is still a very popular second language to learn and is widely spoken.  Romania is also a member of Francophonie.
