The reason I'm asking is because I'm trying to learn Polish. I used to be fluent, but since I always use english, I forgot many words. My mother is Polish and is fluent. I was thinking of starting a plan to make her speak Polish all day every day so I can pick up some words and learn how to talk fluently, and if not fluently, at least enough to hold a conversation. How long do you think it would take for someone to be able to get at a good level? 4 months? 6 months? I already understand everything. It's just when I'm talking, I stop a lot because I don't know the words.. its quite frustrating. I'm definetely not at a beginner level. Maybe intermediate.
