Why aren’t there words with triple consecutive letters

Question

We have words with 2 consecutive letters like book, deep, wall, etc. Why aren’t there words with 3 consecutive letters, let’s say boook, deeep, etc. Why is 2 the maximum?

Answer 1

Because three letters doesn’t really convey any more information than two (and even the second is often redundant). For a word to be spelled with three copies of the same letter, people would need to consistently write it that way, which means there would need to be some benefit to doing it over just doing two. There never has been.
