Yes, we’ve been to Montreal and Quebec City, her French was still useful though. I learned Spanish from a Cuban nun in high school, which was difficult, and encounter mostly Mexican speakers here in So Cal, who tend to speak with a thick regional accent. But I once had an Ecuadorean nanny for my kids and her Spanish was so pure and clear, I could understand everything she said! There are definitely some word differences between Spanish from Spain and from the Americas, just as there are word differences between British English and American English. And apparently even in a small country like Korea there’s a “Seoul accent”.
I highly recommend watching a lot of shows in the language you want to learn, with English subtitles. This accidental immersion in Korean that I stumbled into watching kdramas is really helping me learn, and I realize it is what was missing from my previous language learning.
