We take a look at the language of Molière, as French-speaking culture is celebrated with the "Journée de la Francophonie". France 24's Florence Villeminot takes us through the cultural and linguistic trait which unites more than 270 million people across the globe. And author Anthony Lacoudre tells us why Brits, Australians and Americans actually speak French without realising it, and how English and French enjoy a friendly back and forth when it comes to borrowed vocabulary.
