21,513 20-Letter Anagrams

This series of self-described, self-help books is more than just a collection of collections of word puzzles, in the English language. It is a fun and effective way to progressively assimilate the entire vocabulary of the English language, at your own pace, one word-length at a time, five-letter words (and phrases) on up. The author obsessively digested dozens of English dictionaries into massive lists of words, arranged each of the respective lists into alphabetical order, and then scrambled the spellings multiple times. Each book is dedicated to a single length of word, with thousands and thousands of puzzles up front, and the solutions in back. The solutions are in alphabetical order, which gives away the fact that the solutions to the first anagrams begin with the first letter of the alphabet and the solutions to the last anagrams begin with the last letter of the alphabet. Moreover, one anagram is solved on each page, which practically gives away the solutions to the anagrams immediately before it and immediately after it. It always seemed odd to me that schools do not teach all the one-letter words first, all the two-letter words second, all the three-letter words third, and so forth. It is worth a try.
