Yeah, I have a little bit of an issue with word retrieval, as in I know the idea of what I want to say, but sometimes can't retrieve the right word from my brain to say it. I find that I also ask people to repeat things they have said even if I heard them perfectly fine the first time. I have no idea why I do this. I can write and read perfectly fine. My theory for myself is that I have something wrong with the language center in my brain.
