Webb6 sep. 2024 · Shannon calculated that the entropy of the English language is 2.62 bits per letter (or 2.62 yes-or-no questions), far less than the 4.7 you’d need if each letter appeared randomly. Put another way, patterns reduce uncertainty, which makes it possible to communicate a lot using relatively little information.
