I was going to snarkily make a point about that figure only making sense in the context of grammatical english text, with the example of a randomly chosen 7 letter word being one of 32,909 options. log(32,909) is about 15. Which is of course 1.5 bits per character, and that's generously assuming that a person will actually randomly pick from all those potential options. So sorry for what I almost commented, but now I have to wonder why the entropy of a word on its own is so close to the entropy of a word in a sentence. Am I missing something? Is it just coincidence?
