I think of it like, you know when you're trying to think of a word, and you can't think of it, but you still know the feeling you're trying to portray? Like if you couldn't think of "dangerous" to describe walking close to a cliff. You would still have all the feelings, but not the word. Now imagine that's everything, all the time.
