A year and a half ago, I took upon myself the task of
   cross-referencing 106,000 English words with themselves, using a
   very large, commonly utilized Thesaurus for source data. (I just
   remember it was MTHESAURUS10 - Moby's Thesaurus?)

   Anyway, I threw it into a database. I linked up all the words
   with all the other words to see if any levels or layers came
   out. And they did. A fascinating pattern. These cross-references
   words-which-mean-each-other "out of context" ended up with 5
   levels and a scan through them all, you can kind of see the
   pattern (maybe).

   First level were "whole"type things.
   Second level were "Opposite"type things.
   Third level were "Confusion/Mixed" type things.
   Fourth level were "Things in Detail" or involved "skipping
   around" of some kind.
   Fifth level were words about things that were barely even there,
   like, "blushingly" and words for surgeries which had removal of
   organs like "castration", where only a vacancy was left
   (although vacancy I believe was a level 2 word)

   Anyhow... While the Who, Where, Why, How, When words were all
   somewhere in 1, 2 or 3... "What" was in level 4.

   I compared it to a list of words that toddlers typically know.
   Their words were all level 1 and 2 words and their only level 3
   word was "icky" and "mommy".

   I published it, but it won't make sense to anyone. Just like
   this post. I need coffee or sleep. Probably sleep
