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

There’s only so many sounds a person can reasonably make and we already have enough symbols and other symbol combinations to be covered. Between those two things it’s very easy to avoid three letters in a row and I would imagine convention was to avoid that for readability. How would you pronounce those words? There’s probably a more efficient way to spell them.
