There is some math involved. Words have certain patterns and proportions and a lot of it is learning the mathematical nature of words. The rest is just having a sense for words.

You slowly learn what's good and what's bad. I really started to stay away from using obscure facts that I thought other people would know. There are things you know that no one else in the world knows and you have to realize that.
