1 Here is a description of the source and licensing for the three word
2 lists included in the wordgame package:
6 This file contains the OWL2+LWL lexicon as contained in Michael
7 Thelen's excellent zyzzyva program, available under the GPL from
8 http://www.zyzzyva.net/
10 Michael has the following to say about the lexicon:
12 Zyzzyva's OWL2+LWL lexicon is 100% accurate as verified by the
13 metrics available on the NSA Dictionary Committee's
14 website[*]. Zyzzyva has been used successfully as a Word Judge at
15 many North American SCRABBLE® tournaments, including BAT,
16 Oregon TILE, and the 2006 U.S. SCRABBLE® Open!

20 The relevant information from the dictionary committee website is as
23 If you're not sure you have the correct version of the digital
24 file, here are some statistics you can check. There are
25 currently 101 2-letter words, 1015 3, 4030 4, 8938 5, 15788 6,
26 24029 7, 29766 8, 29150 9, 22326 10, 16165 11, 11417 12, 7750
27 13, 5059 14 and 3157 15. The master file lists all words in
28 lower case in alphabetical order, one per line, with each line
29 terminated by a Unix line break. It is 1763167 bytes long and
30 has BSD checksum ('cksum -o 1') 12722, System V checkum
31 ('cksum -o 2') 24638, 32-bit CRC ('cksum -o 3') 2022312244,
32 ISO/IEC 8802-3:1989 checksum ('cksum') 427611949 and MD5
33 checksum dfd408f47cc1a324eb0ab5577910e4e3.
35 I (Carl Worth) have verified the contents of words.txt as included
36 in the wordgame package with resepct to the word counts listed
37 above as well as the MD5 checksum.
41 I created this file from both words.txt and 2of12inf.txt (described
42 below). It consists of words which appear in OWL2+LWL but that do
43 not appear in 2of12inf.txt. Note that this list does not include
44 the 1083 2-15 letter words that appear in 2of12inf.txt but not in
45 OWL2+LWL nor does it contain the 832 words in 2of12inf.txt that
46 have more than 15 letters.
48 For the purposes of generating obscure.txt, the plurals of
49 uncountable nouns marked with % are considered as included in
50 2of12inf.txt, (that is, they are not considered obscure).
54 This word list is the result of an attempt to create a list of
55 common English words suitable for use in a word game. The list is
56 the result of efforts by Kevin Atkinson and Alan Beale. The list
57 was obtained as part of the 12dicts package from:
