When they first met and were dating, what language did they speak with each other? German? I presume he switched to Swedish as she learned it, yes?
English. He can't speak german, despite his mother was german. She always spoke (very bad) swedish with her children, at least in public. It was said CG didn't allow her to speak german with the children, but I don't know if this is true. Fact is, the children can hardly speak german. It's ridiculous if you see WA for example.
I seem to remember Vic making a speech in German years and years ago (I think its in the "speech" section of the Royal website) and someone singing a birthday song to her in German and she understood. Whether her proficiency was helped by schooling or learning in her adult life idk.
I do find it cute that Daniel was/is learning Portuguese. It must have been hard for Silvia to not share her heritage with her children in terms of language, so being able to help Daniel with his Portuguese must be a nice blessing. I know Vic can speak French too.
Was it German or French that Chris and Madde spoke when they were in public while dating? I've never heard CP speak another language bar Swedish and English (I think?), but I was wondering whether his dyslexia would impact on learning other languages? I really don't know this, so if anyone could offer more information, I would be happy to learn!
