Words are such a central part to the power of your books. And these are words that are both familiar and unfamiliar but there's obviously been a real joy in creating them. Do you actually compile lists of words? No, no. They just come to you when you need them. When I need them, I either make them up or find them there. It's easier than getting up off my chair and going and finding things out. So that's why I don't write realism because it's so much of a bother to go and pester people and ask them questions.
