Petite réflexion de Gabriel Wyner sur ce que veut dire "parler couramment une langue" : savoir parler une langue couramment, ce n'est pas tout connaître, mais être capable d'utiliser ce qu'on connaît pour exprimer ce qu'on a envie de dire.
"Fluency in speech is not the ability to know every word and grammatical formation in a language; it's the ability to use whatever words and grammar you know to say whatever's on your mind. When you go to a pharmacy and ask for "That thing you swallow to make your head not have so much pain," or "The medicine that makes my nose stop dripping water" – THAT is fluency. As soon as you can deftly dance around the words you don't know, you are effectively fluent in your target language." Gabriel Wyner
