These word lists are from the SCOWL wordlist set:
downloads.sourceforge.net/wordlist/scowl-7.1.tar.gz wordlist.sourceforge.net/scowl-readme wordlist.sourceforge.net/scowl-7.1-readme
The SCOWL word lists are used primarily for spellchecking.
I use just the 10, 20, and 35 lists by default.
The following information appears in the scowl-readme file linked above.
And here is a count on the number of in each spelling category (american + english spelling category):
