With French, I’ve gotten pretty good and speaking and reading it.
But for the life of me, I cannot pick it up when someone is speaking it. Especially now since French use a lot of slang, not to mention their silly habit of using “Verlan” to reverse words, like “Cimer” for “Merci”.
Yes, I’ve read about Verlan. And in my experience, native French speakers take delight in frustrating native English speakers who dare to try to converse in French! LOL!
